US greenhouse gas emissions fell 0.2% in 2024 while GDP grew 2.7%, according to Rhodium Group’s preliminary annual estimate. Emissions stand approximately 20% below 2005 levels, the baseline year for the US Paris Agreement commitment. The pledge is a 50-52% reduction by 2030, requiring 7.6% annual reductions every year from 2025 onward to hit the target, a pace the US has achieved only during recessions and COVID lockdowns.
The sector breakdown is instructive. Coal power reached its lowest generation level since 1967, which should have produced a meaningful emissions decline. Instead, transportation (the largest-emitting sector, at roughly 28% of US GHG) rose 0.8%, and power sector emissions ticked up 0.2% due to gas generation filling coal’s exit. Industrial emissions fell 1.8%, largely from lower manufacturing output rather than structural decarbonization. The headline coal-phase-out story is being partially offset by gas and transportation.
The math on the 2030 target is now closed. Even with full IRA implementation through 2025, the trajectory does not reach 50% below 2005 without additional policy intervention, behavioral change in transportation, or structural economic shifts. The realistic scenario for investors is a US that misses its Paris target materially, continues deploying clean power at record pace, and operates with a policy regime that is shaped more by energy security and manufacturing competitiveness framing than by climate-target framing for the near term.
