Forecast scenarios
Projected scenarios from the Factrail model. These describe what may happen under stated assumptions — they are not confirmed facts and may change as new data arrives.

Per-capita CO2 begins a slow decline as decarbonization policy matures
Horizon: Jun 9, 2026 – Jan 1, 2030
Baseline projection that global per-capita CO2 emissions begin a shallow decline from roughly 4.7 tonnes as the multi-year lag on accumulated decarbonization policy starts to express, assuming binding policy continues to strengthen and is not reversed.
Assumptions
Assumes the decarbonization-policy driver continues strengthening (or at least holds near 0.62), the modelled ~5-year policy-to-emissions lag begins to express, no major global recession or energy shock, and deforestation pressure does not surge back. The decline is shallow because the indicator is a slow-moving global aggregate dominated by fossil emissions.
This is a projected scenario, not a confirmed fact.

Global renewable electricity share projected toward ~40% by 2030 on a sustained buildout
Horizon: Jun 9, 2026 – Dec 31, 2030
Under a baseline of continued record-class renewable additions and only gradual subsidy unwinding, Factrail projects the global renewable electricity share to keep rising from 33.8% in 2025 toward roughly 40% by 2030, with persistent fossil-fuel subsidies acting as the main drag on the pace.
Assumptions
Assumes the renewable-buildout driver stays at or near its recent record pace (solar PV dominant, China continuing as the largest contributor), policy support such as the IRA broadly persists, no major grid-integration ceiling is hit before 2030, and fossil-fuel subsidies ease only gradually from their 2022 peak. Pace, not direction, is the uncertain variable.
This is a projected scenario, not a confirmed fact.

Expert article
In the Factrail dataset, Michael Regan appears through a single, tightly scoped action: as the institutional figure associated with the 2024 finalization of the EPA's first federal carbon limits on existing coal plants and new gas plants. The entry treats this as a direct, positively directed contribution to climate-mitigation policy. It is important to be precise about what that means. Factrail does not claim to evaluate Regan's full tenure or character; it records one documented rulemaking, dated 25 April 2024, and asks how that specific event connects, through the causal graph, to measurable welfare outcomes.
What the dataset actually records
The anchoring fact is a policy event: the rule set the first binding federal carbon standards on the United States' largest stationary source of carbon dioxide, the existing coal fleet, alongside limits on new gas generation. In the model this fact links to the decarbonization and climate-mitigation policy driver, which currently carries a moderate-to-high weight of roughly 0.62. That weight reflects a structural judgment rather than a verdict on any one person: binding limits on the power sector are one of the stronger available levers on emissions, because electricity generation sits upstream of so much of the economy.
The fact is marked verified, but with medium confidence. That pairing is deliberate. The event itself is well documented; the size and durability of its real-world effect are not. The rule leaned on carbon-capture technology operating at scale, it drew legal challenges, and its survival across changing administrations was not assured. Each of those factors tempers the expected effect, and the model encodes that caution rather than assuming the rule will deliver its full nominal reduction.
How the action maps to welfare indicators
Through the decarbonization-policy driver, the contribution connects to three welfare indicators, and the recorded rating impacts let us read both direction and rough magnitude. The largest is on global CO2 emissions per capita, an indicator where lower is better and which carries a high importance weight of 0.9; the net impact value of about -0.37 indicates downward pressure on per-capita emissions, the intended direction for a decarbonization measure. A second, closely related effect runs to population-weighted PM2.5 air pollution exposure, with a net value near -0.31. This is an analytically intuitive co-benefit: limits that displace coal combustion tend to reduce fine-particulate exposure, and because PM2.5 is a leading environmental risk factor for premature death, that co-benefit is a direct public-health gain rather than a side note.
The third linkage is to the renewable share of global electricity generation, where higher is better; here the net impact value of roughly +0.25 points the right way, consistent with carbon limits nudging the generation mix toward cleaner sources. Taken together, the three indicators describe a coherent mechanism: pressure on coal, lower per-capita emissions and particulate exposure, and a modest tilt toward renewables.
The positive and negative sides, honestly weighed
Because this profile rests on one fact, the strongest signals point in the same broad direction. The most significant positive contributions are the modeled improvements on emissions and air-quality indicators, and the supportive shift in clean-power share. There is no separately recorded negative rating impact attributed to Regan in this dataset; the counterweight is uncertainty rather than an opposing harm. That uncertainty is real and should be stated plainly. The rule's effect is contingent on technology deployment and legal durability, the contribution size and responsibility factors in the model are deliberately fractional, and a confidence modifier discounts the result further. The EPA, not any individual, is the institutional author, so responsibility is shared by design.
Why this matters
The value of the Factrail entry is not that it crowns a single official as decisive, but that it traces a transparent chain from a documented policy event to welfare indicators that touch climate stability, air quality and the energy transition. The directional reading is positive and the indicators are high-importance, which is why even a hedged, shared-responsibility contribution registers as meaningful. At the same time, the medium confidence and the explicit legal-and-political caveats mean this should be read as a directional, event-bound assessment, not a confirmed measurement of climate impact. It is one slice of a larger and still-contested policy record, presented so that readers can see exactly how the model reached its view.
