The graph above shows US rates of decarbonization (explained here). It shows:
- 2018 actual = -0.01% (the US actually re-carbonized)
- Projected 2019-2029 = 2.3%
- Implied by an 50% reduction in US carbon dioxide emissions by 2030 = 8.4%
- Implied by an 80% reduction in US carbon dioxide emissions by 2050 = 6.6%
Bottom line: Any climate policy proposal should be evaluated in terms of what it does to decarbonization rates. Show your math.
