Weighing GHGs in New York

The report examines the impact of New York's CLCPA greenhouse gas accounting method, which differs from the UNFCCC standard. It finds that the CLCPA approach increases the distance to statutory targets and alters cost-effective abatement strategies, though substantial reductions remain necessary regardless of the method used. The authors argue that marginal abatement cost data for different gases and sectors is essential for evaluating the 2025 New York State Energy Plan.

• The CLCPA's specific accounting method increases the amount of emission abatement required to meet statutory targets compared to the UNFCCC approach, although the 2050 target still requires substantial reductions under either system.
• The impact of the Global Warming Potential (GWP) timeframe on accounting is often similar in scale to the effects of measuring gross instead of net emissions and the inclusion of emissions from outside the state.
• New York's chosen accounting methodology significantly changes the strategy for cost-effective abatement, and the report identifies a need for marginal abatement cost data for various sectors and gases to properly assess the 2025 New York State Energy Plan.
