The figure above provides an update (to 2018) on global decarbonization rates (that is, rate of reduction in carbon dioxide emissions from fossil fuels divided by global GDP, in 2011$ PPP).
- Annual decarbonization 2000-2018 = 1.6%
- Implied by a 50% reduction (from 2000 emissions) by 2030 = 8.4%
- Implied by an 80% reduction (from 2000 emissions) by 2050 = 6.0%
