Energy efficiency gains are too slow for a sustainable climate path
A new International Energy Agency report shows rising investment in energy efficiency and gains in the efficiency of the global economy, but both lag levels needed for a sustainable climate path.
Why it matters: Boosting efficiency is vital to meeting climate goals.
By the numbers: Global energy intensity — that is, energy used per unit of economic output — improved by 1.9% this year.
- That's above the 0.5% improvement in 2020, but well under the 4% annual level this decade in IEA's scenario for net-zero emissions by 2050.
- Global investment rose somewhat, but in IEA's climate-friendly scenario, it would need to triple by 2030.
