New Report Highlights Global Impact of US Climate Action Retreat

US Carbon Emissions on the Rise, Undermining Global Climate Action

The imminent threat of the global temperature exceeding a rise of 2.7 degrees Fahrenheit (1.5 degrees Celsius) above pre-industrial levels calls for immediate reduction in carbon emissions. According to a recent report, however, the US retreat from climate action seriously threatens these mitigation efforts.

Research by scientists from the United Nations Environment Programme (UNEP) revealed a significant increase of 133 megatons in US carbon emissions last year, surpassing other major economies. The report attributes the increase to heightened electricity demand and surge in coal power generation. The US and Russia were also reported to share the highest per capita carbon emissions, with a figure close to 18 tons.

Trump Administration’s Role in Rising Emissions

The report indicates that the policies of the Trump administration contributed to the increase and have worsened the US emissions projections. It is now anticipated that by 2030, emissions could be nearly 0.9 gigatons greater than the projections under the Biden administration policies. It also suggests that the impact of America’s lack of climate action would have global ramifications, with US emissions significantly exacerbating the crisis.

The Trump Administration’s Approach: Dismantle, Repeal, and Rollback

In the past year, the Trump administration has dismantled US climate policy and hindered clean energy growth, while simultaneously expanding domestic oil and gas production. Numerous climate policies from the Inflation Reduction Act were repealed under the One Big Beautiful Bill Act. The administration also rolled back standards for power plant and vehicle emissions, regulations for methane emissions, and expansion of renewable energy.

One of the first actions Trump took as president was to withdraw the U.S. from the Paris Agreement for the second time. The treaty initially aimed to limit global warming to 2.7 degrees F (1.5 degrees C), a goal which is now considered unattainable.

Projected Outcomes and Necessary Reductions

The UNEP report outlines that to limit the overshoot of the projected temperature increase, emissions need to be cut meaningfully. To keep the peak warming around mid-century below 3.1 to 3.2 degrees F (1.7 to 1.8 degrees C), global emissions must be reduced by 18% by 2030 and 45% by 2035. It also emphasizes the need for increasing CO2 removal throughout the century.

Even if all parties to the Paris Agreement meet their current emissions reduction goals and persist in their efforts, the report states that the world would still fall short of achieving the necessary cuts. In such a scenario, there is a 66% possibility of limiting warming to 4.7 degrees F (2.6 degrees C) by 2100.

Impact of US’s Withdrawal from Paris Agreement

The report attributes the current worse-than-expected outcomes partly to the US’s formal withdrawal from the Paris Agreement and revises estimates of historical emissions. The projected warming has increased between 0.4 to 0.5 degrees F (0.2 to 0.3 degrees C) compared to last year’s report, with about half of the higher warming estimate being due to America’s abandonment of its emissions reduction commitments.

The findings of the report are expected to be discussed at the upcoming COP 31, the 31st Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in Türkiye. The conference aims to reach consensus on policies to limit planet-warming emissions, and the certainty of overshooting the aimed temperature rise will bring an urgent need for resolutions. However, despite the US’s significant contribution to the climate crisis, it is doubtful that it will attend the conference.
