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.
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.

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.

Jennifer Granholm's tenure as US Energy Secretary is read in Factrail's model as a strengthening force on the clean-energy transition — not because of rhetoric, but because the documented record shows her department steering large pools of federal capital toward low-carbon technology. The single tracked action behind this profile is concrete and verified, and the model's job is to follow it through the causal chain into welfare indicators, while being candid about where the certainty thins out.
The anchoring fact is the Department of Energy's launch of a $7 billion regional clean-hydrogen hubs program in 2022, recorded as an initiative with medium confidence and a verified status. Under Granholm, the DOE directed federal money — through loans, grants and this hubs program — toward technologies central to decarbonization. The hydrogen-hubs effort is the specific, documented instance the model uses as a proxy for that broader pattern of capital allocation. Crediting the contribution to her department's decisions is more defensible than crediting any particular long-run emissions outcome, because the decisions are observable in a way that downstream climate effects are not.
From the hydrogen-hubs initiative, Factrail draws a causal line to the renewable-capacity-buildout driver, a technology-deployment driver carrying a heavy current weight of 0.85 — one of the more powerful levers in the energy model. Buildout then connects outward to a cluster of welfare indicators spanning energy access, climate pressure, the clean-power mix and air quality.
The strongest recorded effect runs through the renewable share of global electricity generation, a higher-is-better indicator weighted at 0.85, where the net impact is a sizable +0.765. The model's logic here is direct: higher clean-power shares displace fossil generation, cutting both climate and air-pollution harm. The action also pushes on global CO2 emissions per capita — a lower-is-better climate-pressure measure weighted at 0.9 — and on population-weighted PM2.5 air-pollution exposure, where reduced exposure is a direct public-health gain because fine particulates are a leading environmental risk factor for premature death. A further link reaches access to electricity as a share of world population, the foundational welfare measure underpinning health care, education and economic opportunity.
The reservations on this profile are not about intent; they are about durability and the underlying technology mix. Clean hydrogen is a useful illustration of the problem. Its climate benefit is not uniform — it depends heavily on the production pathway, and hydrogen made from high-carbon inputs delivers far less than hydrogen made from genuinely clean sources. So a program can be real, well-funded and well-intentioned while its eventual welfare payoff remains genuinely uncertain.
This shows up directly in the rating impacts, which are mixed in sign. The largest, about +0.32, flows through the global renewable-share channel. Others are positive but smaller. Yet a notable impact near -0.25 runs through the renewable share of German public electricity generation, and another negative value touches the global electricity-access series — reflections of how the same action reads differently against different reference series and deviation baselines rather than evidence that the program harmed those measures. The model is not claiming Granholm's DOE worsened German renewables; it is showing that a single US-centered action carries little explanatory weight against some non-US or already-trending indicators.
The caveats here are about durability and mix, not about intent: the decisions are easy to verify, but the long-run impact of any single program is harder to confirm than the choice to fund it.
A second, blunt limit is political. A number of the initiatives launched under Granholm, including clean-hydrogen funding, were curtailed or cancelled by the succeeding administration in 2025. That fact cuts directly at durability: a program's modeled benefit assumes it runs long enough to compound, and a reversal truncates exactly the multi-year accrual the clean-energy case depends on.
On balance, the available public record supports treating Granholm's tenure as a strengthening force on the clean-energy transition. The direction of her documented choices is consistent, the driver they feed is heavily weighted, and the indicators they touch sit at the center of climate, air-quality and energy-access welfare. What the model withholds is false precision: it credits the decisions, which are verifiable, while declining to overstate the long-run impact of any single program, which is not.
That restraint is the useful part. Energy policy is unusually prone to whiplash, and a transition is only as durable as the institutions and funding streams that carry it. Factrail's reading captures both halves of that reality — a clear positive push toward decarbonization, tempered by an explicit acknowledgment that mix uncertainty and political reversal can erode the very gains the buildout is meant to deliver.
