Are governments doing their “fair share”? - New method assesses climate action

Climate Action Tracker assesses government climate proposals on what’s “fair” and holds warming below 2?C.The Climate Action Tracker (CAT) has developed the most comprehensive method yet of simultaneously assessing the “fairness” and “below 2?C compatibility” of government climate action put forward for the Paris Agreement, expected to be adopted in read more...

China, US and EU post-2020 plans reduce projected warming

For the first time since 2009 the Climate Action Tracker calculates a discernibly lower temperature increase than previously estimated because of new proposed post-2020 actions.Recent announcements by China, the United States and European Union, who comprise approximately 53% of global emissions, indicate a rising level of ambition, which are reflected read more...

China and US increase climate ambition: Improvements needed in 2015

The Climate Action Tracker has undertaken an initial assessment of the recent announcements by the United States and China’s new pledges and proposals on emissions reductions for 2025 and 2030, in the context of the present international negotiations for a new climate agreement to be adopted at the end of read more...

China and the US: how does their climate action compare?

Together, China and the US emit about 35% of today’s greenhouse gas emissions. Current global climate change action is insufficient to limit warming below 2°C. By improving action of China and the US to global best practice, these two largest emitters could decrease domestic emissions to a level compatible with read more...

Below 2°C or 1.5°C depends on rapid action from both Annex I and non-Annex I countries

Deeper cuts needed by all sooner, especially in energy and industry, to keep to 2°CAll governments will have to significantly increase their action on climate change – both before 2020 and after, reducing total global greenhouse gas emissions to zero between 2060 and 2080, to keep warming to 2°C.To achieve read more...

Analysis of current greenhouse gas emission trends

Policy activity has to increase significantly in order to limit global average temperature increase to 2°C above the pre-industrial level. With currently implemented government policies, greenhouse gas emissions are projected to lead to a warming of 3.7°C by the end of this century, about 0.6°C higher than that under the read more...

"Climate shuffle" likely to lead to increased warming

National action on climate change mitigation appears to be joining the international climate negotiations in the new and ever popular “climate shuffle” dance. It involves maximum effort and motion while staying in the same spot…or even, in some cases, going backwards.Recent emissions trends and estimates of the effects of those read more...

2° be or not 2° be

Limiting global warming below 2degC – or even to below 1.5DegC remains technically and economically feasible, but only with political ambition backed by rapid action starting now, the Climate Action Tracker said today.

Governments set world on more than 3°C warming, still playing with numbers

Governments are still set to send global temperatures above 3°C by 2100, even though their agreed warming limit of 2°C is still technically possible, scientists said today. In this update we discuss the 2°C and 1.5°C limits, the future of the Kyoto Protocol and recent clarifications of Parties’ conditionality to read more...

Reality gap: Some countries progress in national polices, but many risk failing to meet pledges

In this update, the Climate Action Tracker provides insights for Brazil, the USA, Mexico, Japan and South Korea on actions on climate change, new economic and energy data, government policies and announcements and developments at the UN climate talks.
