Q&A: Why deals at COP28 to ‘triple renewables’ and ‘double efficiency’ are crucial for 1.5C

(CarbonBrief, 21 Dec 2023) COP28 president Sultan Al Jaber has urged governments to agree on global goals to triple renewables capacity and double the rate of energy efficiency improvements by 2030.

This call from Al-Jaber is supported by the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA), and political momentum is building.

This month, a US-China joint statement on climate change backed tripling renewables to substitute coal, oil and gas power and bring about “post-peaking meaningful absolute power sector emission reduction”.

The context for these targets is a world that remains dramatically off course against global climate goals, with recent assessments pointing to warming of 2.4-2.7C above pre-industrial levels by 2100.

In its recent report on how to get back on track, the IEA said tripling renewables, doubling efficiency and slashing methane emissions 75% by 2030 would provide 80% of the emissions cuts needed for 1.5C.

This Q&A explains what tripling renewables and doubling energy efficiency means – and why they are the two biggest actions the world can take to get back on track for 1.5C, even though they would be insufficient on their own to meet the target.
