In 2023, Calpine Corporation reported total carbon emissions of approximately 48.9 billion kg CO2e, all of which were classified as Scope 1 emissions, with no reported Scope 2 or Scope 3 emissions. This marks an increase from 2022, when total emissions were approximately 44.4 billion kg CO2e, also entirely from Scope 1. The company has consistently reported emissions solely from its direct operations, with no emissions attributed to purchased goods or services. Calpine's emissions data shows a trend of increasing emissions over the years, with 2021 emissions at approximately 43.6 billion kg CO2e and 2020 emissions at approximately 45.5 billion kg CO2e. The company has not set specific reduction targets or initiatives, as indicated by the absence of documented reduction targets or commitments to frameworks such as the Science Based Targets initiative (SBTi). As a major player in the energy sector, Calpine's climate commitments and emissions profile are critical in the context of global efforts to reduce greenhouse gas emissions. However, without specific reduction initiatives or targets, the company's long-term climate strategy remains unclear.
