Climate Action Tracker Global update – Glasgow’s 2030 credibility gap: net zero’s lip service to climate action
Glasgow has a credibility gap between talk and action. In this briefing, the Climate Action Tracker (CAT) has calculated that if all governments met their 2030 targets, we would have 2.4˚C of warming in 2100. But right now, current policies put us at 2.7˚C. Read More

A seismograph for measuring the transformation to net-zero greenhouse gas emissions – Discussion Paper
This discussion paper sketches the idea of a “transition Seismograph” to measure and detect the transformation to net-zero greenhouse gas emissions before it is seen in projections of greenhouse gas emissions. Read More

State of Climate Action 2021
The State of Climate Action 2021 identifies 40 indicators across key sectors that must transform to address the climate crisis, and assesses how current trends will impact how much work remains to be done by 2030 and 2050 to deliver a zero-carbon world in time. Read More
The Emissions Gap Report 2021
This is the twelfth edition of the United Nations Environment Programme (UNEP) Emissions Gap Report. It assesses the gap between estimated future global greenhouse gas (GHG) emissions if countries implement their climate mitigation pledges and the global emission levels from least-cost pathways that are aligned with achieving the temperature goals of the Paris Agreement.

In this report, the Climate Action Tracker (CAT) explores several sets of scenarios for the evolution of the passenger vehicle stock in China, in order to inform on emission reduction and electricity demand implications. Read More
Publication in Nature Climate Change: Wave of net zero emission targets opens window to meeting the Paris Agreement
This article published in “Nature Climate Change” analyses the recent wave of national net zero targets showing that there is significant momentum which could bring the temperature limit of the Paris Agreement within reach. Read More
Climate Action Tracker Global update: Climate target updates slow as science ramps up need for action
This briefing provides an overview of the development in climate action over the last year and illustrates the new CAT assessment of the countries we analyse, based on our updated method. Read More
National ‘fair shares’ in reducing greenhouse gas emissions within the principled framework of international environmental law
This Climate Policy journal article introduces a conceptual framework to assess the progress, implementation, and impact of climate action by sub- and non-state actors. Read More
NDC Design
We evaluate the NDCs along key elements that are critical for the success of the NDC ambition cycle: 1. Increased mitigation ambition; 2. Comprehensiveness; 3. Implementation plan; and 4. Transparency. Read More
Global climate action from cities, regions and businesses – 2021
This report is the third and the latest edition of the series since 2018 that take stock of climate action by cities, regions and businesses and their global aggregate impact on greenhouse gas emissions. The 2021 edition focuses on the progress of non-state and subnational actors toward their emissions reduction targets. Read More
Greenhouse gas emission scenarios in nine key non-G20 countries: An assessment of progress toward 2030 climate targets
This study compares greenhouse gas (GHG) emissions projections in 2030 under current policies and those under 2030 mitigation targets for nine key non-G20 countries, that collectively account for about 5 % of global total emissions today. These include the four largest non-G20 fossil CO2 emitting Parties to the UN climate convention pre-Paris Agreement (Iran, Kazakhstan, Thailand and Ukraine) and one of the largest land-use GHG emitters in the world (Democratic Republic of the Congo).

The Challenges of Assessing “Collective Progress”: Design Options for an effective Global Stocktake process under the UNFCCC
This paper examines the questions of what an effective Global Stocktake process would look like, and what information and data are needed to support it. Read More
Climate Action Tracker Global update: Climate Summit Momentum
Climate action announcements at US President Biden’s Leaders Summit on Climate, together with those announced since September last year, have improved the Climate Action Tracker’s warming estimate by 0.2°C. End of century warming from these Paris Agreement pledges and targets is now estimated to be 2.4°C. Read More
