Brazil hosts COP30 in Belém
In November 2025 Brazil hosted COP30 in Belém under Lula’s presidency, the first Amazon-city COP. Neighbouring 2023 deforestation drop is the parent enforcement year. In the causal graph this event strengthens Decarbonization and climate-mitigation policy, a driver that weakens Global CO2 emissions per capita — an improving welfare path.

In November 2025 Brazil hosted COP30 in Belém under Lula’s presidency, the first Amazon-city COP.
Context
The UNFCCC sat. Neighbouring 2023 deforestation drop is the parent enforcement year. Neighbouring 2024 fires are a cost cousin. Parties brought NDCs. He did not write every party’s target.
Amazon enforcement 2023 is neighbouring. 2024 fire season is neighbouring. G20 Rio 2024 is neighbouring diplomacy.
The President of Brazil heads the federal executive, sanctions statutes, and commands the armed forces as a political principal. He does not write STF judgments, INPE satellite pixels, a US tariff proclamation, or a Venezuelan CNE tally. Congress, governors, Petrobras, and coalition partners share specific files.
Why it matters
The path is decarbonisation policy: a completed Amazon-host COP is a dated climate-diplomacy instrument, remaining domestic fires named.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

Evidence
The sources behind this fact and its verification state.

What the sources establish
Presidency of Brazil carries the official instrument or communique. Reuters records the same dated act independently.
Established: November 2025 COP30 in Belém, independently reported.
Not established: a unique later global-emissions coefficient from Pará, or that 2024 fires never sat.
The UNFCCC ran the COP. Parties negotiated. Ibama still had a domestic file.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Brazil hosts COP30 in Belém, not a later speech about Brazil hosts COP30 in Belém.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He hosted as president. The UNFCCC ran the COP. Parties negotiated. Ibama still had a domestic file. That limit is the alternative to treating office-holding as authorship of every later series.
