Pathways for limiting global warming to 1.5° and 2°C generally involve netzero greenhouse gas (GHG) emissions economy-wide near mid-century and halving emissions over the next decade The updated US pledge to reduce net emissions 50 to 52% by 2030 would represent a tripling of the pace of historical reductions. We report on a six-model intercomparison of potential actions to reach the US target of at least 50% GHG reductions by 2030. We find that models highlight the central roles of clean electricity and electrification, the large scale of deployment needed relative to historical levels and scenarios with only current policies, and a range of benefits from near-term action.
