What Changed: ECP has maintained a portfolio of gas power plants over the past several years; these assets were not included in the emissions metric of the 2024 analysis. In 2025, ECP acquired a portfolio of three gas power plants and one coal plant from ArcLight and Blackstone, including the Gavin coal plant, which is one of the dirtiest coal plants in the United States. As of July 2026, ECP was in the process of selling the three gas plants to Talen Energy. ECP’s standard score worsened due to an 11.2 million tons CO2e increase in downstream coal emissions attributed to their purchase of coal assets. ECP had no coal tracked in 2024. Additionally, ECP does not provide any new information on recent carbon credits or offsets.
