Energy Innovation has released version 4.0 of the United States Energy Policy Simulator (EPS), an open-source model updated to incorporate the impacts of the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA). The updated model features a rebuilt electricity sector with hourly dispatch and expanded power plant types to better analyze the financial incentives and emissions trajectories of the U.S. energy system through 2050.

The report reviews the European power sector in 2015, noting a record increase in renewables generation that was largely offset by increased electricity demand and a decline in nuclear and hydro output. Consequently, power sector CO2 emissions fell by only an estimated 0.5% in 2015, following a much larger 7.5% drop in 2014. The author maintains a forecast that EU ETS emissions will fall 21% from 2014 to 2020, potentially leading to 30% economy-wide CO2 cuts by 2020.

This research paper by the Stockholm Environment Institute examines the greenhouse gas (GHG) emissions implications of the Keystone XL pipeline, specifically focusing on how the infrastructure might increase global oil consumption by lowering prices through increased supply.

This policy brief by the Stockholm Environment Institute examines the climate implications of ending the issuance and renewal of U.S. government leases for fossil fuel extraction on federal lands and offshore waters. The analysis suggests that such a policy could significantly reduce global CO2 emissions and align U.S. production more closely with the goals of the Paris Agreement and a 2°C warming pathway.

This working paper outlines a strategy for the United States to meet its 2025 emissions targets and achieve deeper long-term reductions through a combination of existing administrative authorities, state actions, and future Congressional legislation.
