Our global temperature projections show that the world is heading towards an irrecoverable overshoot of 1.5°C unless governments rapidly accelerate emissions reductions.Aggregated climate action has now essentially stalled for five consecutive years, with positive and negative actions cancelling each other out:Current policies are projected to lead to 2.7°C of warming read more...

This report unpacks electrification to build a common understanding of what it means, how it is measured and the role it will play across the key end-use sectors: transport, buildings and industry in a 1.5°C-aligned future. Decades of insufficient mitigation action means that pursuing the Paris temperature goal requires rapid read more...

As New Zealand approaches its 2026 general election, it is important to reflect on the recent adverse changes in climate policies.In this briefing, we set out the problems with the country's climate policies, and some recommendations for whichever government is elected on November 7. Climate action and policy is central read more...

Our memo examines Türkiye’s power sector transformation over the past decade. While the government has successfully expanded new wind and solar generation, increasing the share of renewables in the power mix, total energy use – and fossil fuel use in the power sector – has also been increasing.As co-host of read more...

Our memo examines Chile’s power sector transformation over the past decade, showing that large-scale renewable energy deployment can exceed expectations when supported by a strong and predictable policy framework, effective procurement mechanisms and clear long-term decarbonisation signals.However, Chile’s experience also demonstrates that if new renewable generation capacity is not matched read more...

The current energy crisis triggered by the US–Israel war on Iran has once again placed energy security at the centre of geopolitical tensions. It marks the third major shock to the global energy system since 2020, highlighting the inherent vulnerabilities of fossil fuel-based energy systems.The way governments respond to energy read more...

Key findingsTripling renewables, doubling energy efficiency and cutting methane by 2030 and beyond would cut warming rate by a third in ten years, and halve it by 2040.It would cut projected warming this century significantly (about 0.9˚C from 2.6˚C to 1.7˚C).Scaled up financial support to achieve this will be needed read more...

Ten years after the Paris Agreement, the world stands at a critical juncture in the fight against climate change, with little to no measurable progress in warming projections - for the fourth consecutive year, as Climate Action Tracker’s latest global update, released at the COP30.Almost none of the 40 governments read more...

Article 6 of the Paris Agreement was designed as a tool to enhance climate action, enabling countries to cooperate in achieving their climate targets. This cooperation must lead to real, additional, permanent and not double counted emissions reductions that support sustainable development—not simply shift responsibility from one country to another. read more...

Halfway through 2025 and, despite an early deadline this year, only 11 of the 40 countries the Climate Action Tracker (CAT) assesses have submitted a 2035 climate target (NDC). Of them, just one has put forward a domestic target that is 1.5˚C compatible if followed by increased international finance.CAT countries read more...
