The report highlights that Poland accounted for 70% of methane leaks from active coal mines in Europe in 2018. It argues that these emissions have a greater climate impact than the CO2 emissions from the Bełchatów Power Plant when using a 20-year warming horizon. The analysis identifies JSW and PGG as the dominant emitters, with the Budryk mine being the largest single source in Europe. The document recommends accelerating emission reduction plans, closing high-emitting mines, banning the release of captured methane, and integrating methane into the EU ETS by 2030.

The report uses the WIS:dom-P optimization model to compare four capacity expansion scenarios for the Southeast US: the current SE IRP, an economic IRP without an RTO, an SE RTO, and an SE RTO that retains uneconomic nuclear plants. The findings indicate that the SE RTO scenario is the most economic, offering cumulative savings of $383.7 billion by 2040 and the highest job creation. Retaining nuclear plants further reduces emissions, saving an additional 156.76 million metric tonnes of CO2 by 2040 at a minimal additional cost. The study also highlights the role of variable renewable energy (VRE) and storage in meeting seasonal demand peaks and the importance of transmission expansion in a coordinated regional market.
