Emission cuts available by 2030 from options costing up to 100 US dollars per tonne

The IPCC's assessment of how far mitigation options costing 100 US dollars per tonne of CO₂-equivalent or less could reduce global greenhouse gas emissions in 2030, compared with the 2019 level.

What it covers

Geography
World
Basis
An assessed potential for 2030, not a forecast of what will happen: the reduction that options costing USD100 tCO₂-eq⁻¹ or less could deliver, from the sectoral literature. The statement is a lower bound ("at least").
Unit
percent of 2019 global greenhouse gas emissions (%)
