UN Forecasts First-Ever Decline in Global Emissions Despite US Policy Reversal

UN Forecasts Historic First Decline in Global Emissions

For the first time ever, global greenhouse gas emissions are projected to fall within the next decade, according to the latest United Nations analysis. After decades of relentless growth—including record highs set just last year—new national pledges, combined with rapid investment in clean energy, have begun to bend the emissions curve downward. The UN Framework Convention on Climate Change (UNFCCC) now expects about a 10% reduction by 2035, compared with 1990 levels—though this is far short of the 60% cut scientists say is required to keep global warming below the critical 1.5°C Paris Agreement threshold.

What Drives the New Downward Trend in Emissions?

The shift comes amid an unprecedented global rollout of renewable energy, especially solar PV and wind, which—for the first time—are providing more electricity than coal worldwide. Massive investments in green infrastructure are now cropping up in major economies, including China, India, the EU, and the UK. Although the US contributed a plan under former President Joe Biden, current policies under President Trump have diverged, weakening the anticipated reductions and casting doubt on long-term progress.

The Challenge of Policy Reversals in the United States

The UN’s projections notably factor in ambitious climate commitments made by Biden, including rejoining the Paris Agreement and substantial investment in emission reductions. However, recent reversals under Donald Trump—such as the loosening of vehicle emission standards, fossil fuel expansion, and withdrawal of federal support for renewables—may stymie the pace and magnitude of US emissions cuts. This “homework gap” between pledges and enacted policies highlights why the latest projections are contingent and why future summits, such as COP30 in Brazil, will be so critical.

Are These Promises Enough to Avoid Dangerous Climate Change?

Climate scientists argue the current trajectory is insufficient to avoid severe warming and catastrophic impacts. To meet Paris goals and limit warming to 1.5°C, emissions must decrease by nearly 60% by 2035—a target which current pledges fall short of by a factor of six. If implemented fully, current nations’ plans could reduce emissions by 17% relative to 2019 and result in peak emissions before 2030, followed by sharp declines by 2035, with most reaching net zero by 2050. However, uneven national commitments and frequent policy changes complicate the outlook and increase the risk of missing these critical climate thresholds.

The Rising Impact of Clean Energy and Technology

Renewables are fundamental to progress, with solar and wind leading the charge globally. China’s record-setting installations of solar and wind in 2024 offer hope for a structural shift away from coal-powered growth. If major emitters like the EU and China continue to coordinate, experts believe it could tip global markets decisively toward clean alternatives, accelerating overall emissions decline.

Economic Implications and the Need for Speed

Even as emissions begin to fall, the UN warns that climate-related disasters—droughts, storms, wildfires—continue to kill thousands, disrupt economic stability, and cost billions annually. Slower-than-needed progress means global temperatures are likely to overshoot 1.5°C before 2040, creating significant risks for economic growth, food security, and public health. The UN and UK climate advisers have already advised governments to prepare for at least 2°C warming by 2050 if action stalls.

Why COP30 and National Plans Matter Right Now

This year's “nationally determined contributions” (NDCs) are more comprehensive than ever before, increasingly covering all sectors of the economy with greater credibility—and including adaptation, finance, and technology transfer. But not every country is fully on board, with some missing deadlines and others submitting incomplete plans. UN climate chief Simon Stiell insists that COP30 must send a clear signal of strong, coordinated climate action, urging every nation to move faster with concrete outcomes in all key areas.
