Climate Action Tracker briefing: three key near-term actions could bring projected warming below 2˚C

Climate Action Tracker analyzes that tripling renewables, doubling energy efficiency, and cutting methane by 2030 and beyond could reduce the warming rate by a third within ten years and halve it by 2040. At COP 28 in Dubai, 2023, during the first Global Stocktake (GST1) discussion, governments negotiated and agreed on a clear set of 2030 energy and methane goals aligned with limiting warming to 1.5°C. These goals included tripling renewable energy capacity, doubling the rate of energy efficiency improvements, and cutting methane emissions.

In this Climate Action Tracker analysis, we show for the first time the huge climate benefits if governments were to implement what they have negotiated and agreed for these three critical energy and methane goals. We evaluate the global benefits of governments taking concerted action to deliver on the goals by 2030 and 2035, both in terms of emission trajectories and warming implications.

This analysis underscores a clear imperative: the accelerated expansion of renewable energy, expansion of electrification, and the associated phase-out of fossil fuels are indispensable to achieving the Paris goal. Delivering on these agreed targets would not only narrow the emissions gap but also lay the foundation for a resilient, low-carbon global economy. The COP30 Presidency's action agenda represents a key space to mobilise commitment in delivering these goals.
