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...

The Climate Action Tracker has updated our assessments of 23 of the 32 countries whose development on climate action we track.While some progress has been made since November, most governments’ policies are still not on track towards meeting their Paris Agreement commitments, many of which are in themselves far from read more...

The Climate Action Tracker has updated its estimates of global progress towards the Paris Agreement goals, with some positive and negative findings: Significant improvement on climate action globally, despite US rollbacks0.2°C improvement in climate action since 2016, reducing projected warming by 2100 to 3.4°C. For the first time since the read more...

Global leadership on climate is changing, with positive developments on coal use in China and India likely to reduce projected global carbon emissions by roughly two to three billion tonnes by 2030 compared to our estimate last year. The recent, highly adverse rollbacks by President Trump are unlikely to have read more...

US President Donald Trump’s 28 March Executive Order formalises his pre-election commitments to unwind science based climate action in the United States, but this will not stop the clean energy transition now underway globally.President Trump’s Executive Order, if codified as a commitment under the Paris Agreement, would downgrade the US read more...

The rapid entry into force of the Paris Agreement has created the legal basis for countries to increase their level of action and ambition to meet the 1.5degC warming limit over the next two years in the lead-up to 2018. The Climate Action Tracker (CAT) has evaluated the starting point read more...
