A major scaling up of clean energy this decade
In line with IEA’s Net Zero roadmap, the world needs to double progress on energy efficiency & triple renewable power
capacity by 2030. A major scaling up of clean energy globally is critical to bring down demand for all fossil fuels.

Emerging and
developing economies
There are bright spots for clean energy investment in India, Brazil and some other emerging & developing countries,
but almost all of the growth in clean energy investment in recent years has been in advanced economies & China

Revised NDCs lower energy-sector emissions, but fall short of
aligning with long-term ambitions
Revised NDCs boosts the reduction in targeted emissions by around 4 Gt in 2030,
however they are not yet fully aligned with countries’ long-term targets
