US decarbonization rates by president, measured election year to final year of term. Data as in yesterday’s post.

• To hit -80% CO2 by 2050 requires -6.8%/year (assuming 2.0% GDP growth/year)
• Democrats have done better than Republicans
• Trump is the worst (with two years of data so far)
• None have been remotely close to rate needed for deep decarbonization

The figure above shows US rates of decarbonization 1992 to 2018. Decarbonization is a technical term that refers to a decrease in the ratio of carbon dioxide emissions to gross domestic product. The concept is derived from the Kaya Identity, which is a very powerful tool for understanding emissions and their potential to be reduced through policy action. This post provides an update on global decarbonization rates, based on new data from the EIA and OMB.
