- Assuming no significant changes in non-energy CO2 or other GHG emissions, sustaining last year’s 0.66% annual decline in energy-related CO2 for the next three years should be sufficient to achieve the US Copenhagen Accord target of a 17% reduction below 2005 levels by 2020. But this pace of decarbonization will still leave the US considerably short of it’s Paris Agreement pledge of a 26-28% reduction from 2005 levels by 2025, as highlighted in our annual Taking Stock report last May. A 1.7-2.0% average annual reduction in energy-related CO2 emissions is required over the next eight years to meet that target, assuming no changes in other gasses. To achieve long-term emissions reductions consistent with the 2-degree temperature target in the Paris Agreement, an even faster rate of decarbonization is required.
Long way to go, but good to see some hard numbers on progress.
