6 routes to a 50% reduction in U.S. emissions by 2030

President Joe Biden's goal is a 50 percent reduction in U.S. greenhouse gas emissions or more by 2030 compared to 2005 levels. Reaching 50 percent would mean cutting about 3,300 megatons of carbon dioxide-equivalent emissions. The first bar shows how much had been cut by 2019. The other six show different routes to achieving that goal.

The bars show net greenhouse gas reductions in megatons of carbon dioxide-equivalent emissions. The six analyses are EDF-NEMS: Environmental Defense Fund-National Energy Modeling System; GCAM-USA-AP: Global Change Analysis Model for the U.S.; LBNL: Lawrence Berkeley National Laboratory models; PATHWAYS: Regional Investment and Operations Model supply-side model and Energy PATHWAYS demand-side model; REGEN: US Regional Economy, Greenhouse Gas and Energy model; REGEN E+: US-REGEN model with accelerated electrification; USREP-ReEDS: US Regional Energy Policy-Regional Energy Deployment System model.
