UN Warns World Is Falling Behind Climate Goals as US Policy Reversals Raise Concerns

The United Nations has warned that the world is falling significantly behind its climate goals, with current government policies putting the planet on track for approximately 2.8°C of global warming by the end of this century.

According to the United Nations Environment Programme (UNEP), even if countries fulfill their existing climate commitments, global temperatures could still rise by approximately 2.6°C.

The findings, published in the Emissions Gap Report 2026 on October 21, highlight growing concerns over insufficient climate action and recent policy reversals in the United States.

Global Emissions Remain a Major Challenge

The report estimates that global greenhouse gas emissions reached approximately 58.4 billion tonnes of carbon dioxide equivalent in 2025.

Although emissions growth has slowed, the world has not achieved the sustained reductions necessary to meet the Paris Agreement’s goal of limiting global warming to 1.5°C.

UNEP estimates that global emissions must decline by 18% by 2030, 45% by 2035 and 69% by 2040 compared with 2025 levels to limit the extent of warming above that threshold.

However, existing national commitments fall considerably short of these targets.

US Climate Policy Reversals Raise Concerns

The report identifies recent changes in US climate policy under President Donald Trump as contributing to the global emissions challenge.

These changes include extending coal power plant operations, weakening vehicle fuel efficiency standards and ending federal tax incentives supporting wind and solar energy projects.

The United States has also moved away from previous climate commitments, raising concerns about international efforts to reduce greenhouse gas emissions.

According to the assessment, US policy reversals could contribute approximately 0.1°C of additional global warming by 2100.

UN Calls for Stronger Global Climate Action

UNEP has urged governments to accelerate emissions reductions through renewable energy expansion, reduced dependence on coal and stronger methane regulations.

The report recommends significantly increasing renewable electricity capacity while reducing coal generated electricity by at least 75% by 2035.

It also emphasizes the importance of reducing methane emissions by 25% by 2035 and 40% by 2040.

Climate Risks Could Intensify Without Action

The UN warns that continued warming could increase risks to glaciers, coral reefs, oceans and vulnerable ecosystems.

Although exceeding the 1.5°C threshold is increasingly difficult to avoid, stronger climate policies could still reduce the severity and duration of future warming.

The report concludes that immediate international cooperation, stronger government commitments and effective implementation remain essential to limiting long term climate damage.
