New Climate Pledges ‘Barely Move the Needle,’ UNEP Report Warns

Despite new climate pledges from governments, the world is still heading toward dangerous levels of warming, warns a new United Nations Environment Programme (UNEP) report. The Emissions Gap Report 2025: Off Target reveals that current national commitments would limit temperature rise to only between 2.3°C and 2.5°C by the end of this century, far from the 1.5°C goal set under the Paris Agreement. The findings highlight that, while promises have been made, real progress in cutting emissions has remained worryingly slow.

Climate Commitments Show Little Progress

The world remains off track to limit global warming to 1.5°C, even with the latest national pledges, according to the United Nations Environment Programme’s Emissions Gap Report 2025: Off Target. The report finds that current commitments, even if fully implemented, would only limit the rise in global temperatures to between 2.3°C and 2.5°C by the end of the century. This represents only a slight improvement from last year’s projection of 2.6°C to 2.8°C, primarily due to refined estimation methods rather than substantial emission cuts.

Global greenhouse gas emissions reached 57.7 gigatonnes of carbon dioxide equivalent in 2024, a 2.3% increase from the previous year. UNEP’s analysis reveals that while some nations have updated their Nationally Determined Contributions (NDCs) under the Paris Agreement, the overall impact remains insufficient. As of September 2025, only 60 parties representing about 63% of global emissions had submitted or announced new 2035 targets.

The Growing Gap Between Pledges and Action

To align with the 1.5°C target, global emissions must fall by around 55% from 2019 levels by 2035. However, current pledges point to a reduction of only 15%, leaving a significant implementation gap. This shortfall means that the world is likely to breach the 1.5°C threshold within the next decade, with severe implications for ecosystems, food security, and human health.

The report highlights that the largest emitters, particularly G20 nations, hold the key to shifting global trends. Together, they account for nearly 77% of global emissions, excluding the African Union. While renewable energy capacity has expanded and costs have fallen, policy inertia and uneven financing remain significant obstacles. UNEP stresses that turning pledges into action requires stronger governance, effective policy enforcement, and accelerated international cooperation.

Finance and Policy Failures Continue to Slow Progress

One of the report’s central messages is the persistent failure to mobilise adequate climate finance, especially for developing nations. Many of their climate pledges are conditional on financial and technological support from wealthier countries, which has not materialised at the promised scale. This financial shortfall limits vulnerable nations’ ability to transition to low-carbon pathways and adapt to worsening climate impacts.

UNEP calls for a fundamental redesign of the global financial architecture to unlock greater investment in mitigation and adaptation. The report also notes that while technological solutions exist and have become more affordable, implementation remains uneven. Closing this gap will require countries to prioritise transparent climate governance, scale up renewable energy deployment, and ensure that emissions-reduction targets translate into measurable action on the ground.

A Narrowing Window for Climate Stability

Scientists warn that the current trajectory leaves little room for error, as every fraction of a degree increases the frequency and intensity of climate events. Rising emissions threaten to push vulnerable regions into cycles of extreme heat, water scarcity, and crop loss. The UNEP report serves as another urgent reminder that, while the world has the tools to act, the pace of progress is far from sufficient to avoid irreversible damage.

With COP30 approaching, global leaders face mounting pressure to close the gap between pledges and practice. The coming decade will determine whether countries can transform ambitious promises into meaningful action. Without rapid and collective effort, the world risks locking in a dangerously warmer future well beyond the Paris Agreement’s goals.
