# Lisa Badum

Lisa Hildegard Badum (born 2 October 1983 in Forchheim) is a German politician of Alliance 90/[The Greens](/organizations/the-greens) from Upper Franconia in Bavaria. She has been a member of the Bundestag since 24 October 2017, associated with the Bamberg constituency, and was returned at the 2025 federal election on place 5 of the Bavarian Green state list. In the 21st Bundestag she is the parliamentary group's spokesperson for climate policy.

She studied political science at the University of Bamberg, including an Erasmus year in Thessaloniki in 2006–2007, and was a student senator in 2005–2006. Before entering parliament she worked from 2010 to 2013 as a research assistant in the Fürth constituency office of Green member Uwe Kekeritz, and from 2012 to 2017 in the citizen-energy department of Naturstrom AG. She has sat on the Forchheim district council since 2008.

In the 19th electoral term she was the Greens' climate-policy spokesperson and a full member of the environment committee. In the 20th term she was the group's lead member on the Committee on Climate Action and Energy, chaired the Subcommittee on International Climate and Energy Policy and the German–Greek Parliamentary Group, and headed the Bundestag delegation to the conferences of the parties to the [United Nations Framework Convention on Climate Change](/facts/united-nations-framework-convention-on-climate-change). From 2021 to 2024 she was president of the Association of German–Greek Societies, and since 2022 she has been a vice-president of the German–Israeli Society.

Her legislative work has centred on an earlier coal exit, wind power in Bavaria, and the social design of climate policy, positions she has carried into opposition after the 2025 election. In constituency 235 Bamberg in 2025 she received 20,762 first votes (13.4 percent), behind [Thomas Silberhorn](/people/thomas-silberhorn) of the [Christian Social Union in Bavaria](/organizations/christian-social-union-in-bavaria) (39.4 percent), who kept the direct mandate; Green second votes in the constituency were 12.6 percent. In the 21st Bundestag she is a full member of the Committee on the Environment, Climate Protection, Nature Conservation and Nuclear Safety, a deputy member of the Budget Committee, and deputy chair of the German–Greek Parliamentary Group.

## Early life and education

### Childhood and schooling

Lisa Hildegard Badum was born on 2 October 1983 in Forchheim, in Upper Franconia, Bavaria. The Bavarian returning officer's register of nominations for the Bundestag election of 23 February 2025 records that full name, with 1983 as the year of birth, Forchheim as both place of birth and residence, and member of the Bundestag as the occupation. She told the Nordbayerischer Kurier in 2017 that she had lived in Forchheim since birth. Bundestag biographies for the 19th and 20th electoral terms, which the parliament notes rest on members' own information, describe her as Roman Catholic and unmarried; the biography for the 21st term still lists her as unmarried.

She attended the Anna-Grundschule in Forchheim and then the Ehrenbürg-Gymnasium, where a 2021 profile on nordbayern.de reported that she was already involved in women's rights and equality. The 19th-term Bundestag biography states that she passed the Abitur there in 2003, and she told the Kurier that her advanced courses were social studies (Sozialkunde) and history. A profile on nordbayern.de of 12 September 2013 reported that at twelve she still wanted to become a writer or a housewife.

She has dated a political turn to the age of fourteen, when a book about female genital mutilation among African women left her, she told the Kurier, shaken that people were mutilated only because they were women. The 2013 profile reported that she soon afterwards founded the Forchheim group of the women's-rights organization Terre des Femmes and that, at sixteen, she stood in the pedestrian zone with a poster showing the practice. The Kurier instead described her as joining the organization and collecting donations there, and quoted her view that being a feminist and arguing for equal rights was, for her, the most natural thing in the world. The 19th-term Bundestag biography lists Terre des Femmes among her memberships.

### University of Bamberg

From 2003 to 2010 Badum studied political science at the Otto-Friedrich-Universität Bamberg, the University of Bamberg. A curriculum vitae on her website describes the completed qualification as a Diplom in political science (Diplom-Politikwissenschaften).

In 2006–07 she spent an Erasmus Programme year in Thessaloniki, Greece. The 20th-term biography calls the stay a period of study abroad; nordbayern.de describes two semesters, and the 2013 profile a year lived in the city. None of those accounts names the host institution. From 2005 to 2006 she was a student senator at Bamberg. She has written that in that role she campaigned against tuition fees and for gender mainstreaming.

She was active in the university's Green student group. She told the Kurier that an internship at the Bamberg daily Fränkischer Tag produced a report on why so many young women stayed away from politics, and that a further internship with Ursula Sowa, then the Bamberg member of the Bundestag for Alliance 90/The Greens, led her to join the party in 2005. She described Sowa as attentive to people, idealistic and credible, and the Greens as the party which, through its gender quota, pursued equality of women and men the most consistently. The 2021 nordbayern.de profile likewise dates party membership to 2005, during the degree, and completion of the degree to 2010.

## Career before the Bundestag

### Constituency staff

From 2010 to 2013 Badum was a *wissenschaftliche Mitarbeiterin*, a graduate-level aide, in the Fürth constituency office of Uwe Kekeritz, a member of the Bundestag for Alliance 90/The Greens. Kekeritz held constituency 243, Fürth, on the Bavarian state list. A profile from the [Heinrich Böll Foundation](/organizations/heinrich-boll-foundation) described him as a Bundestag member since 2009 and as the Green group's spokesperson on development policy.

The post overlapped a private-sector job. On 12 September 2013, while Badum was a Green candidate, nordbayern.de reported that she spent three days a week on public relations for Naturstrom AG and two days supporting Kekeritz in Fürth. Biographies she later gave the Bundestag do not use the same start date for the company work. The 19th-term text said she had been in Naturstrom's citizen-energy department since 2013; the 20th-term text dated that job from 2012 to 2017 and kept 2010 to 2013 for the Fürth office. The 21st-term biography mentions only the Naturstrom years.

### Citizen energy

Naturstrom AG, registered in Düsseldorf, employed her from 2012 to 2017 in its *Abteilung Bürgerenergie*. The Bundestag's register of disclosable interests records that pre-membership employment with a right to return to the post. Its 2015 annual report named her as an employee based in Forchheim and as a board member of Bürgerenergie Bayern e.V.

Citizen energy — local ownership of renewable projects, often through energy cooperatives — was then being reshaped by statute. Feed-in payments under the Renewable Energy Sources Act had encouraged new cooperatives during the Energiewende. A survey by the Deutscher Genossenschafts- und Raiffeisenverband, covering cooperatives founded since 2006, counted 129 new energy cooperatives in 2013 and 54 in 2014. Chair Eckhard Ott attributed the fall mainly to the 2014 amendment, including auctions he said favoured larger firms. Those cooperatives had invested €1.67 billion and installed 933 megawatts.

Bavaria added the 10H rule: a wind turbine had to stand at least ten times its height from the nearest settlement, more than two kilometres once machines passed 200 metres, or lose its privileged status outside built-up areas and require a municipal zoning plan. Citing the Fachagentur Windenergie an Land, Bayerischer Rundfunk reported that applications averaged 22.1 turbines a month from January 2010 to the agency's 4 February 2014 cut-off, and 2.6 a month from March 2014 to March 2021.

Bürgerenergie Bayern e.V., based in Pfaffenhofen an der Ilm, says it was founded in April 2014 to promote a decentralised energy transition, a citizen-owned energy industry, and environmental and climate protection, and that it speaks for about 250 Bavarian citizen-energy cooperatives — about a quarter of those in Germany — plus municipal utilities. Its chair, Markus Käser, later said twelve cooperatives had founded it in response to 10H. Badum has sat on the board since 2014. The Bundestag lists the post as honorary, and the association assigns her the seat for Upper Franconia. In 2015, when Naturstrom counted 22 member companies, a subsidiary began selling a Bavaria-wide regional green-electricity tariff with the network, marketed locally by those companies.

## Local politics and party offices

### Forchheim district council

Badum has been an honorary member of the district council (Kreistag) of the Forchheim district since 2008, according to her Bundestag biography for the 19th electoral term. The unpaid seat is still listed in her disclosures for the 21st term. Those biographies state that the entries rest on information supplied by the member.

*The Forchheim district council at its first session after the 2026 municipal election, including the swearing-in of members.*

In the March 2014 municipal election, Alliance 90/The Greens gained one seat and held six of 60, three of them filled by women. Badum was already deputy chair of the Green group. In March 2012 that group, chaired by Karl Waldmann, adopted two motions: one requiring collectively agreed wages in district contracts for building and services, and one for the district to start buying fair-trade goods for its events. Badum said low pay, temporary-agency rates and mini-jobs would later return as a cost to taxpayers through basic income support.

Energy sites came up in the same period. In June 2012 a majority of the [Free Voters](/organizations/free-voters), the Social Democratic Party and the Greens, 26 votes to 23, approved an update of the regional plan that retained wind-priority areas, including land in the Franconian Switzerland nature park. Waldmann argued for turbines at Oberngrub inside the park. The Christian Social Union had wanted those areas removed, citing tourism and the landscape, and voted against the update. In 2014 the Energie- und Klima-Allianz Forchheim reported that the council had passed, by 29 votes to 25, a resolution the alliance had sent to every group in May against Bavaria’s planned “10-H” rule, which would have kept a turbine about ten times its height—roughly 2,000 metres—from housing.

Council parties also sit on the district Jobcenter advisory board, with employers, trade unions and welfare associations. In January 2015 the board elected Badum chair and Peter Ehmann of the welfare associations deputy chair. She said the district then had more than 400 refugees, that moving them into work should be a focus even though permission to work still depended on residence status, and that jobs for single parents should be another priority.

In February 2021 she and the Green group called for a half-hourly Wiesenttalbahn, a restored passing loop at Kirchehrenbach, covered bicycle stands and buses timed to the trains.

She was re-elected in 2020. A gallery of the new 60-member council published on 18 March 2020 places her among 11 Green members. The state statistical report on the elections of 8 March 2026 records that previous Green result as 18.2 percent and 11 seats. In 2026 the Greens received 13.4 percent and eight seats, six of them held by women; turnout was 71.8 percent, and Badum was again among the Green members. At a sitting reported on 1 October 2026, during debate on a budget freeze and a building scheme, she asked whether only one electric-vehicle charging point was planned for a teachers’ car park.

### Offices in the Bavarian Greens

Badum has written that she joined the Greens in 2005 through the Green university group at the University of Bamberg, and in particular through Ursula Sowa, then the Bundestag member for Bamberg. The Bundestag record notes that she was a student senator at the university in 2005 and 2006.

Her biography for the 19th term listed membership of the extended state executive of the Bavarian Greens from 2012. The archived biography for the 20th term dates the later posts: spokesperson of the state women’s working group (Landesarbeitskreis Frauen) from 2014 to 2018, and, from 2016 to 2018, spokesperson of the state energy working group (Landesarbeitskreis Energie) and of the party in Upper Franconia.

On 22 October 2016 the Upper Franconia Greens’ autumn assembly in Kulmbach elected her the district’s lead candidate for the 2017 Bundestag election. District spokesperson Christine Schoerner spoke in that role, and the account of the meeting described Badum as already speaking for the state energy and women’s bodies.

In the Forchheim district association, a members’ meeting reported on 7 June 2026 enlarged the executive from five seats to nine. The association named Badum and Barbara Poneleit as its spokespersons and Martin Distler as chair of the Green group on the district council, and it reported a membership rise of about 30 percent since January 2024.

## Bundestag elections

In elections to the Bundestag, each voter has two votes. The first vote (*Erststimme*) is cast for a candidate in a constituency; the second vote (*Zweitstimme*), cast for a party's state list, decides how many seats that party receives, and list candidates are seated in the order of the list. Since the election of 23 February 2025, a party candidate who finishes first in a constituency receives that seat only if the party's second votes cover it.

Lisa Badum of Alliance 90/The Greens, who lives in Forchheim, contested the Bamberg constituency in Upper Franconia, Bavaria, at the federal elections of 2009, 2013, 2017, 2021 and 2025. The constituency was number 236 through 2021 and number 235 in 2025. The Federal Returning Officer's boundary lists for 2017 and 2025 name the same area: the independent city of Bamberg and specified municipalities in the districts of Bamberg and Forchheim. She did not win the direct seat at any of these elections. She entered the Bundestag in 2017 from the Bavarian Green state list and was returned from that list in 2021 and 2025.

### Candidacies in 2009 and 2013

On 27 September 2009 Badum was the Green candidate in constituency 236 and was placed 15th on the party's Bavarian list. The constituency election committee reported 177,197 people eligible to vote and 129,049 ballots cast, a turnout of 72.8 percent. Of 127,486 valid first votes, Thomas Silberhorn of the Christian Social Union in Bavaria received 62,548 (49.1 percent) and was declared directly elected. Andreas Schwarz of the [Social Democratic Party of Germany](/organizations/social-democratic-party-of-germany) was second with 26,044 (20.4 percent), Sebastian Körber of the Free Democratic Party third with 13,590 (10.7 percent), and Badum fourth with 11,726 (9.2 percent). The 15th list place did not produce a seat.

At the election of 22 September 2013 she stood only on the list, in 13th place, and was again not elected. In constituency 236 the direct mandate went to Silberhorn, the incumbent, with 65,723 first votes (52.2 percent). The SPD candidate received 28,794 (22.9 percent). The Green first-vote total was 10,283 (8.2 percent); that figure was for the constituency candidate, not for Badum, whose Bundestag biography records the 2013 candidacy as a list place only. Turnout was 70.5 percent of 179,923 eligible voters.

### Elections of 2017, 2021 and 2025

Badum was the Green constituency candidate again in 2017, 2021 and 2025. The seat kept the number 236 in 2017 and 2021. For the election of 23 February 2025 it was numbered 235; the Federal Returning Officer's map of that constituency covers the city of Bamberg and parts of the two surrounding districts.

On 24 September 2017, with Badum 11th on the Bavarian Green list, Silberhorn held the direct seat on 60,675 first votes (42.1 percent) and was also 12th on the CSU list. Schwarz, the SPD constituency candidate, was second with 29,475 (20.4 percent). [The Alternative](/organizations/the-alternative) for Germany received 16,603 (11.5 percent), and Badum 13,194 (9.2 percent). Turnout was 79.6 percent of 182,513 eligible voters. The Federal Returning Officer listed her as elected for Bavaria at list place 11, while also a candidate in constituency 236.

A Green nominating meeting in constituency 236 on 23 September 2020 again selected her as the direct candidate for 2021. At the election of 26 September 2021 Silberhorn won with 54,726 first votes (37.0 percent). Schwarz was second with 28,123 (19.0 percent), and Badum third with 22,728 (15.4 percent), up from 9.2 percent in 2017. Turnout was 81.4 percent. She was re-elected at place 9 on the Bavarian Green list; the official Bavarian return records her, born in 1983 and resident in Forchheim, as seated from list place 09, and records Silberhorn as elected in constituency 236.

On 23 February 2025, in constituency 235, Silberhorn again took the direct mandate, with 61,044 first votes (39.4 percent). The runner-up was Michael Adam Weiß of the AfD, with 28,891 (18.7 percent). Schwarz, the SPD constituency candidate, received 22,569 (14.6 percent) and was elected from place 13 on the Bavarian SPD list. Badum received 20,762 (13.4 percent). Green second votes in the constituency were 19,476 (12.6 percent). Turnout was 85.8 percent of 181,281 eligible voters. The Federal Returning Officer listed Badum, Lisa Hildegard, born in 1983, as elected for Bavaria at list place 5, and as a candidate in constituency 235 as well.

## Parliamentary roles

### Committees and spokesperson posts

Since she entered the Bundestag on 24 October 2017, Lisa Badum’s posts have combined committee seats with offices in the parliamentary group of Alliance 90/The Greens. The membership tables record the seats. The biographical text, which the Bundestag notes rests on the member’s own information, records faction roles such as policy spokesperson.

In the 19th legislative term (2017–2021) she was a full member (*ordentliches Mitglied*) of the Committee on the Environment, Nature Conservation and Nuclear Safety and a deputy member (*stellvertretendes Mitglied*) of the Committee on Economic Affairs and Energy. The biography names her, for that term, the Green group’s spokesperson for climate policy (*Sprecherin für Klimapolitik*). Parliamentary groups organise such work in working groups and working circles (*Arbeitsgruppen* and *Arbeitskreise*) of members specialised by field. Those bodies prepare bills, motions, questions to the government and the positions the group takes in committee; the spokesperson is the member named to lead and present that line.

In the 20th term (2021–2025) a new Committee on Climate Action and Energy shadowed part of the Federal Ministry for Economic Affairs and Climate Action and led on energy and climate bills, including the Energy Industry Act, the Renewable Energy Sources Act, the Building Energy Act and the Federal Climate Action Act. Badum was a full member and the Greens’ *Obfrau* there, and a deputy member of the Economic Affairs Committee and the Committee on [Foreign Affairs](/organizations/foreign-affairs). Each group names one *Obfrau* or *Obmann* per committee as its leadership’s contact. They shape the group’s course, agree agendas and the planning of business, and report the detailed work back to the group.

The same roll lists her as a deputy member of the 2nd Committee of Inquiry. Set up on 4 July 2024 under Stefan Heck (CDU/CSU), with eleven members plus substitutes, it examined how the government adapted energy supply after Russia’s attack on Ukraine on 24 February 2022, including whether the remaining nuclear plants might keep running, and how that was explained to parliament and the public. It adopted its report on 13 February 2025.

In the 21st term she is a full member of the Committee on the Environment, Climate Action, Nature Conservation and Nuclear Safety and a deputy member of the Budget Committee. The environment committee was constituted with 38 full members, five of them from the Greens, including Badum; it deals with climate instruments, extreme weather, biodiversity, resource use and nuclear waste. The Budget Committee deliberates annual federal spending and reviews execution of the budget. The Green group lists her as its climate-policy spokesperson. A press release published on 11 May 2025 by *Der Neue Wiesentbote* said she would again carry that responsibility and lead an internal working group, Koordination Klima & Energie, to align the group’s climate and energy initiatives and bills.

### Parliamentary groups and delegations

On 8 April 2022 the Committee on Foreign Affairs constituted a Subcommittee on International Climate and Energy Policy, the first it had created for that subject, and the members elected Badum chair. The parent committee set it up because international climate and energy policy is tied to foreign and security policy. It had eleven full members and deputies, distributed by group strength, with two full Green seats; Badum was both chair and a full member. As elected chair she presided over a preparatory body whose task the Foreign Affairs Committee had defined, rather than over a standing committee of the Bundestag. The biography for the 20th term also describes her as head of the Bundestag’s delegation to the UN climate change conferences. In a travel report published by the Green group she wrote that, as subcommittee chair, she led that delegation at the 29th conference (COP29) and organised its joint appointments, while the federal government conducts the treaty negotiations.

The Bundestag’s *Parlamentariergruppen* are separate from committees. They are cross-party associations of members, without statutes or rules of procedure of their own, that keep up a dialogue with parliaments in partner countries. At the start of each term the Council of Elders (*Ältestenrat*) fixes their number and structure, and chairs are distributed according to the strength of the parliamentary groups. The biography records Badum as chair of the German–Greek Parliamentary Group in the 20th term. A Bundestag account of the group’s visit to Greece in June 2024 likewise identifies her as its chair and as leader of that delegation. In the 21st term the membership roll lists her as deputy chair (*Stellvertretender Vorsitz*) of the same group.

Outside that system, she initiated a cross-party *Parlamentsgruppe Braukultur* at the end of January 2022. A trade report counted about 50 members, including MPs from the CDU, CSU and SPD, and described it as an initiative on beer culture and the brewing industry, distinct from an older association dating from 1974. The German Brewers’ Association later wrote that the circle, also called a *Parlamentskreis*, was founded by the Upper Franconia member in 2022 and had grown to more than 60 members; Badum linked the founding to slow pandemic aid for brewery inns. It is an informal circle of members, not a bilateral *Parlamentariergruppe* constituted by the Council of Elders.

## Climate and energy policy

### Coal exit and fossil fuels

On 3 July 2020 the Bundestag and the Bundesrat adopted a phase-out requiring hard-coal and lignite plants to close by the end of 2038 at the latest, and earlier if possible, by 2035. The Bundestag passed the bill by 314 votes to 237 and, the same day, structural aid of up to €40 billion for the coal regions. The dates followed the January 2019 report to Chancellor [Angela Merkel](/people/angela-merkel) of the Commission on Growth, Structural Change and Employment, adopted with one vote against, which had set 2038 and a 2032 review of a possible move to 2035.

Economics minister Peter Altmaier (CDU) called the statute a legally secure "generational project". Alliance 90/The Greens voted against. Co-leader [Annalena Baerbock](/people/annalena-baerbock) said the coalition had replaced the commission compromise with a "coal-extension law" for another 18 years. [The Left](/organizations/the-left-slovenia), the FDP and the AfD opposed it too, and critics attacked operator compensation of a good €4 billion. Badum told the *Nürnberger Nachrichten* that voting no was necessary "because it is in fact a coal-extension law". Another 18 years "far exceeds our CO2 budget" and was "a climate debt at the expense of future generations", gilded "on the backs of the taxpayers". Her group had backed payments to workers and structural aid, not compensation for profits she said the plants would not earn; the valuation report appeared only the evening before the vote. In March 2021 the [European Commission](/organizations/european-commission) opened an inquiry into €4.35 billion—€2.6 billion for RWE and €1.75 billion for LEAG—and on 11 December 2023 cleared the RWE payment under EU state-aid rules.

In September 2022 Badum accused PreussenElektra, Bavaria's nuclear regulator and the state government of a "dubious" account of whether Isar 2 could run on: no spare fuel, then fitness for stretch-out operation, then a valve to be replaced in October. She said she no longer trusted a reserve operation. In April 2026, with fuel prices high after the war begun that March by the United States and Israel against Iran, Chancellor [Friedrich Merz](/people/friedrich-merz) said he would not "put the core of our energy supply at risk" for exit dates that were "unrealistic". Greenpeace's Martin Kaiser said the Rhenish district was already on a 2030 path. Badum called that a push "deeper into fossil dependence", negligent on climate and short-sighted economically.

### Wind power in Bavaria

Article 82 of the Bavarian Building Code withholds the usual outer-area privilege from wind turbines unless, outside stated exceptions, they stand at least ten times their height—hub height plus rotor radius—from homes in zoned and built-up areas. Transitional clauses refer to plans adopted before 21 November 2014. In listed cases, including priority zones, repowering and pre-existing forest, the distance is instead 1,000 metres, and neither minimum applies in areas designated under the federal Wind Energy Area Requirement Act. Under Horst Seehofer the CSU had sided with campaigns against turbines and new power lines. When Markus Söder's party announced easements on 29 April 2022, Badum called them half-measures: the tenfold rule had "throttled" wind in Bavaria and Upper Franconia, and "10H must be abolished completely" if a 2 percent land target was to be met.

By 2026 the block was federal auctions under the Renewable Energy Sources Act, where windier northern bids beat the south at the Federal Network Agency. About 1,000 turbines were waiting, against a fleet of 1,182; in the first half of 2026 Bavaria connected eleven. Badum said more than 200 of some 1,000 projects in the pipeline were already permitted but had no award. In early October she and economy minister [Hubert Aiwanger](/people/hubert-aiwanger) (Free Voters) jointly demanded a "southern quota" for Bavaria and Baden-Württemberg. "We need more wind turbines in the south so that electricity generation is regionally balanced", he said—after accusing the Greens in June of a "climate fetish". Badum, [Jamila Schäfer](/people/jamila-schafer) and Sascha Müller told the CSU Bundestag group to enforce the quota Söder had long demanded, "instead of continuing to watch its own party colleague Reiche bury the project". Economics minister Katherina Reiche rejected a fixed quota as too expensive and preferred better auction terms for the south, although the Union group's own amendments included one.

### Heating, buildings and social climate measures

In September 2023, under Chancellor [Olaf Scholz](/people/mig-olaf-scholz), the Bundestag amended the Building Energy Act by 399 votes to 275, with five abstentions. Each new heating system must use at least 65 percent renewable energy: from 2024 in new development areas, and in existing buildings only once municipal heat plans exist—by mid-2026 above 100,000 inhabitants, by mid-2028 elsewhere—so owners can choose district heat, a heat pump or another lower-carbon system. Robert Habeck called it "a good law". An Öko-Institut estimate put the emissions cut through 2030 at about three-quarters of an earlier draft. CSU leader [Alexander Dobrindt](/people/alexander-dobrindt) said "this law makes people poor". Jens Spahn called it "madness" and a "stimulus programme for populists".

In April 2026 Badum said guilds and municipalities had adapted, and that polarisation now came from government: "The CDU wants to reverse everything Robert Habeck introduced, especially the heating law." She asked for a social Deutschlandticket, lower electricity tax and a climate payment of €200 a person each year, "given back to citizens unconditionally". She said Environment Minister [Carsten Schneider](/people/carsten-schneider) had few allies and that the climate council already found his programme socially unbalanced.

The cabinet forwarded a replacement on 13 May 2026. Renamed the Building Modernisation Act, it was passed in mid-July, promulgated on 28 July and applied in its main parts from 29 July. The 65 percent rule was removed, so gas and oil boilers may be installed again beside heat pumps, district heat, hybrids and biomass. A "bio staircase" requires at least 10 percent climate-neutral fuel from January 2029, 15 percent from 2030, 30 percent from 2035 and 60 percent from 2040, with heating fuels meant to be fully climate-neutral by 2045. A green-gas quota from 2028 was left to another statute by 1 December 2026. Tenants are to be shielded from an uneconomic new boiler, and the act is to be reviewed in 2030. Union deputy Sepp Müller said the reform replaced "paternalism with freedom of choice". [Katharina Dröge](/people/katharina-droge) called it "an accelerant for the climate crisis", and Deutsche Umwelthilfe announced a constitutional complaint. Badum had labelled the draft a "chaos law" and a "biogas staircase to nowhere", costly for tenants and "a gift for the natural-gas lobby". The government told her no reliable estimate of biogenic supply was then possible. BDEW and the municipal utilities' association VKU asked where fuel already counted on by industry, power plants and transport would come from.

## Climate diplomacy and bilateral relations

### UN climate conferences

In the 20th electoral term of the Bundestag (2021–2025), Lisa Badum of Alliance 90/The Greens chaired the Subcommittee on International Climate and Energy Policy, which the Foreign Affairs Committee set up on 8 April 2022. The Bundestag biography, drawn from members’ own disclosures, lists her for that term as head of the Bundestag delegation to the UN climate conferences. The *Nürnberger Nachrichten* reported that she led the delegation to the [2022 conference (COP27)](/facts/2022-united-nations-climate-change-conference) in Sharm El Sheikh; the biography’s wording also covers the [2023 conference in Dubai (COP28)](/facts/2023-united-nations-climate-change-conference) and the [2024 conference in Baku (COP29)](/facts/2024-united-nations-climate-change-conference). In November 2025 she was in Belém for COP30. *[Der Spiegel](/organizations/der-spiegel)* identified her there as the Greens’ climate-policy spokesperson; the 21st-term biography does not repeat the delegation-head title.

In the Bundestag debate of 14 December 2023 she called the COP28 outcome the start of an exit from the fossil era and “the result of excellent climate diplomacy” by the European Union and the federal government, and she said 133 states had backed a tripling of renewable energy.

At COP29 she joined U.S. senator Ed Markey and Canadian senator Rosa Galvez in a call by more than 130 lawmakers against new fossil-gas export infrastructure. Markey’s office said the text demanded an immediate moratorium on new liquefied natural gas projects, including an end to public financing and permitting, and that the appeal had grown from about 25 signatures at COP28. A profile of her as a 2026–27 Obama Foundation Europe Leader attributes that mobilization to “a nearly 80% decrease” in projected European LNG import-capacity growth over the following year. The Institute for Energy Economics and Financial Analysis, which did not tie the change to the appeal, reported that Europe’s LNG regasification capacity grew 13 percent in 2023 and 8 percent in 2024 and was expected to grow 2 percent in 2025 as projects were cancelled or closed.

From Belém, *Der Spiegel* reported, she wrote to Chancellor Friedrich Merz after he said journalists travelling with him had been glad to leave and that Germany was one of the most beautiful countries in the world. She wrote that she was ashamed, had apologized to people from Pará, and asked him to apologize to President [Luiz Inácio Lula da Silva](/people/env-person-lula) and the people of Belém; Merz later said he did not regard relations with Brazil as damaged.

### Relations with Greece and Israel

The Bundestag biography records an Erasmus Programme year in Thessaloniki in 2006–07. In the 20th term she chaired the German–Greek Parliamentary Group; in the 21st the Bundestag lists her as deputy chair. From 2021 to 2024 she was president of the Vereinigung der Deutsch-Griechischen Gesellschaften, the Association of German–Greek Societies. *Griechenland.net* reported her election, at an annual meeting, as successor to Sigrid Skarpelis-Sperk, who was named honorary president. She did not stand again; on 28 September 2024 in Weimar the association unanimously elected Christian Goiny of the Berlin [House of Representatives](/organizations/house-of-representatives). Founded in 1961, it then described itself as the umbrella for 34 societies.

As chair she led a delegation to Greece from 17 to 20 June 2024, with Carsten Träger (SPD), [Thomas Rachel](/people/thomas-rachel) (CDU/CSU) and Rainer Semet (FDP), the group’s first such trip since May 2016. In Athens, Western Macedonia and Thessaloniki the talks covered energy, equality, youth exchange and the effects of Russia’s war against Ukraine. The delegation met Parliament President Konstantinos Tassoulas, friendship-group chair Athanasios Plevris and the German–Greek Youth Office, and visited power-company and wind and solar sites in the former lignite region. In the Bundestag’s account, Badum said relations were “good again, but could be better,” and that a new friendship treaty might open another chapter without forgetting the German occupation. She said coal’s share of Greek electricity had fallen from more than 70 percent in 2004 to about 5 percent; the report put youth-office exchanges since its founding three years earlier at about 10,000.

Since 2022 she has been a vice-president of the Deutsch-Israelische Gesellschaft, the German–Israeli Society. About three weeks after the Hamas attacks of 7 October 2023, *Bild* reported that she and fellow Green member Johannes Wagner visited Kibbutz Kfar Aza and the Shura base, where bodies were still being identified, at the invitation of the [American Jewish Committee](/organizations/american-jewish-committee), with legislators from other EU countries. Quoted by *Bild*, she described bloodstained rooms in the kibbutz, said repeated shots to women’s faces and mutilation of bodies showed the attackers’ ideology, and said it was staggering how many of those killed had worked for peace and a two-state solution. On 7 November 2023 the society listed her, as vice-president, among speakers at a memorial at the Brandenburg Gate.

## Civic roles and recognition

### Associations and board posts

Within three months of taking office, and of any later change, members of the Bundestag must notify the President of reportable outside posts: company boards, roles in public-law bodies, and leading or advisory roles in associations and foundations that are not purely local. Checked notices are published on the member's biography.

Lisa Badum's current notice, as a member of Alliance 90/The Greens, lists one company post: from 17 July 2025 she has sat on the supervisory board of the Erzeugergemeinschaft für Energie in Bayern eG in Bodenkirchen, a Bavarian cooperative whose site presents solar fields, wind turbines and biogas plants. Several association roles are marked honorary. She is a board member of Bürgerenergie Bayern e.V. in Pfaffenhofen an der Ilm, whose statutes set the purpose of promoting a decentralized energy transition and citizen-owned energy in Bavaria; the board page assigns her the seat for Upper Franconia. She is an honorary assessor of Energie- und Klima-Allianz Forchheim e.V., which works on awareness of climate protection and adaptation in the Forchheim district, and a co-opted honorary adviser of Verein Nationalpark Steigerwald e.V. in Burgwindheim, a party-neutral association supporting more unmanaged forest in the Steigerwald. The notice also records an honorary seat on the Forchheim district council and a right to return to her pre-mandate employment at NATURSTROM AG in Düsseldorf.

Under benefits for political activity, the Wilhelm und Else Heraeus-Stiftung in Hanau is entered for deploying its stipend holders, at €18,000 in 2025 and €27,000 in 2026. Its programme "Wissenschaft trifft Politik" places recent physics PhDs with members for about three months and pays the fellows €4,500 a month; in 2024 Kira Deltenre supported Badum's office on climate and energy.

The archived 19th-term biography, based on her own statements, also listed memberships not then published as formal side posts: Terre des Femmes, a women's-rights organization; the Bund Naturschutz in Bayern, which calls itself Bavaria's oldest and largest environmental association; Verein Nationalpark Nordsteigerwald; and the Bürgerinitiative pro Wiesenttal ohne Ostspange, a citizens' group opposing the Ostspange road. Her vice-presidency of the Deutsch-Israelische Gesellschaft since 2022, and her presidency of the Vereinigung der Deutsch-Griechischen Gesellschaften from 2021 to 2024, are covered with her work on Greece and Israel. From 11 June 2025 the disclosure lists her as liquidator of the Deutsch-Griechische Gesellschaft Mittelfranken e.V. in Nuremberg.

### Awards and leadership programmes

In 2015 the federal family ministry named Badum among 20 recipients of the Helene Weber Prize, given for honorary work in local politics. On 11 June 2015 [Manuela Schwesig](/people/manuela-schwesig), then federal minister for women and a member of the Social Democratic Party, presented the prizes at the Französische Friedrichstadtkirche in Berlin. Given then for the third time, it is meant to strengthen municipal politics and draw more women into local mandates, and is named for Helene Weber, one of the four women among the framers of the Basic Law, who pressed for the equality clause in Article 3. Bundestag members nominated the candidates, and more than 100 women applied. Elisabeth Schwerin and Aferdita Suka received main prizes of €10,000. The others, including Badum, received €500 for local activities, individual coaching, and a place in the Helene Weber Kolleg, the ministry-funded cross-party network for women in local politics run by the Europäische Akademie für Frauen in Politik und Wirtschaft in Berlin.

The Obama Foundation lists Badum in its 2026–2027 Leaders Europe cohort and identifies her as a member of the [German Bundestag](/organizations/german-bundestag). Leaders Europe is an eight-month virtual programme for people in government, civil society and the private sector, with weekly group sessions, monthly peer groups and individual coaching. On 21 October 2026 the *Fränkischer Tag* in Bamberg carried a report on her participation.

## Reception and disputes

### Disputes over climate legislation

In September 2019, as climate spokesperson of Alliance 90/The Greens, Badum told *Der Tagesspiegel* the grand coalition’s climate package was, for the Greens, no longer salvageable. The paper headlined the interview with her line, “Das ist doch plemplem”. When the Bundestag passed the coal phase-out law on 3 July 2020, the Greens voted no. Badum told *Nordbayern* it was a “coal-extension law”: another 18 years of coal power, a “climate debt at the expense of future generations”, and a weak path “gilded” “on the taxpayers’ backs”, making the [Paris Agreement](/facts/paris-agreement) goals less likely. The Greens backed aid for workers and regions, not company compensation for alleged lost profits.

The 2023 Buildings Energy Act drew the loudest argument about cost. In *Das Parlament* she said buildings caused 40 percent of carbon-dioxide emissions and that heaters last about 30 years. Her “red line” was any further promotion of gas boilers. She called the Free Democratic Party block on the first reading profiling, admitted that the government had explained the bill badly, and blamed “massive” misinformation “deliberately spread” by the gas lobby, citing *Bild* and Union contacts. Hubert Aiwanger, Bavarian economy minister for the Free Voters, said the “heat-pump law” was driving the heating transition “into the wall”. In June 2026, at the first reading of the successor Building Modernisation Act, economy minister Katherina Reiche of the [Christian Democratic Union](/organizations/christian-democratic-union-of-germany) promised to replace “heating compulsion” with technological choice. [Alternative for Germany](/organizations/alternative-for-germany) member [Marc Bernhard](/people/marc-bernhard) called the biofuel staircase “Robert Habeck’s heating hammer through the back door”. Social Democratic Party building minister [Verena Hubertz](/people/verena-hubertz), who had negotiated the earlier act, said that plan “did not work in practice”.

Badum called the rollback the new polarisation. In the *Frankfurter Rundschau* in April 2026 she said guilds had accepted the heating law and municipalities were planning heat networks, and that undoing Habeck’s measure was “simply a party-tactical manoeuvre”. She called environment minister Carsten Schneider weak and said Chancellor Friedrich Merz was pushing Germany “deeper into fossil dependence” by questioning the statutory coal exit. On 7 June 2026 Aiwanger rejected her call for new climate money and for Reiche to abandon what Badum had termed a “gas fetish”. The Greens, he said, were ruining industry and the public purse with a “climate fetish” that did not help the global climate; competitors, including China and the United States, gained.

### Public criticism and cross-party alliances

In Bavaria the standing fight has been turbine distance. From 2014 the Christian Social Union’s 10H rule required about ten times a machine’s height from the nearest settlement, often more than two kilometres, or the project lost privileged status. Interior minister Joachim Herrmann called it a “citizen-participation law”, not a ban; the CSU later blamed species rules, lawsuits and weaker southern wind, not 10H. In May 2022 Badum called it “prevention planning” that had choked wind in Upper Franconia and left glass and porcelain plants short of renewable power. Partial CSU changes were “half-baked”, and Minister-President Markus Söder’s emphasis on longer nuclear lifetimes was “politics of yesterday”.

The two later made a narrow joint demand. On 2 October 2026 *inFranken* reported a field video in which they asked for a “southern quota” in federal wind auctions for Bavaria and Baden-Württemberg. Aiwanger said that otherwise the South needed large power lines and a more fragile grid. Badum said about 1,000 Bavarian turbines were planned and more than 200 approved without an award, because auctions favoured the north. CSU member Thomas Silberhorn, from the Bamberg district, backed fairer southern terms. Mayors warned that about 100 Upper Franconian projects, on the order of a billion euros, were at risk from the federal plans.

Other objections have been local or about disclosure. On 8 January 2024, at a protest of about 1,000 tractors outside Bamberg’s Brose Arena against cuts to agricultural-diesel relief, she met a whistle concert sharper than the boos for SPD colleague Andreas Schwarz. She said ending the diesel privilege and the vehicle-tax refund together was “too much and wrong”. In June 2026 a *Spiegel* and Abgeordnetenwatch ranking of outside earnings put her 34th, at €45,000. She said that was false: the figure was a Wilhelm and Else Heraeus Foundation grant for physicists in her office—€18,000 recorded for 2025 and €27,000 for 2026—paid to the fellows, as the register states, not to her or her party. The published criticism concerns cost, housing distance and industry, not a personal scandal.
