After officially rejoining the Paris Agreement, the Biden administration is now preparing a new 2030 Paris Agreement target - or Nationally Determined Contribution (NDC) that is expected to be announced in time for the Leader’s Climate Summit on Earth Day (22 April).The CAT’s analysis indicates that the new US NDC read more...

The recent wave of net zero targets has put the Paris Agreement’s 1.5°C within striking distance. The Climate Action Tracker (CAT) has calculated that global warming by 2100 could be as low as 2.1°C as a result of all the net zero pledges announced as of November 2020. Included in read more...

In this briefing, we examine the COVID-19 recovery packages of five major emitters – China, EU27, India, South Korea and the USA; we present the global temperature update, taking into account the economic impact of COVID-19; and we share key insights from the updated assessments for 13 of the 36 read more...

While national emission trends are a useful tool for measuring government progress towards meeting the Paris Agreement 1.5˚C temperature limit at a global level, each government will have to address its own sectors, each with their own, different baseline. What should government sectoral benchmarks be? Will they meet the global read more...

The COVID-19 pandemic presents the world with an unprecedented policy challenge: not only will it have a severe impact on the global economy likely to exceed that of both the 2008-09 Global Financial Crisis and the Great Depression, it will take place against the backdrop of the ongoing climate crisis.In read more...

Under current pledges, the world will warm by 2.8°C by the end of the century, close to twice the limit they agreed in Paris. Governments are even further from the Paris temperature limit in terms of their real-world action, which would see the temperature rise by 3°C. An ‘optimistic’ take read more...

The last year has seen growing public concern and the formation of global movements pushing governments for serious action in the face of rising emissions and escalating climate impacts.2018 saw energy-related emissions reach yet another historic high after significant net greenhouse gas increases, 85% of which came from the US, read more...

Staying within the Paris Agreement 1.5˚C temperature limit requires rapid, large-scale systemic transformations to fully decarbonise the global energy system by 2050.Transformations of the speed and scale required have occurred historically when systems reached a transformation point: the moment when a previously novel technology, behaviour or market model achieved critical read more...

The Climate Action Tracker (CAT) estimate of the total warming of the aggregate effect of Paris Agreement commitments and of real-world policy shows little change. If all governments achieved their Paris Agreement commitments the world will likely warm 3.0°C—twice the 1.5°C limit they agreed in Paris. Underneath the lack of read more...

Supported by the ClimateWorks Foundation, the European Climate Foundation and the We Mean Business Coalition, this CAT report develops a set of climate action benchmarks for countries, sectors and subnational entities that a broad range of actors can use. Those benchmarks aim at helping users to assess if recent developments read more...
