In 2023, Calpine Corporation reported total carbon emissions of approximately 48.9 billion kg CO2e, with all emissions classified under Scope 1. The company has not disclosed any Scope 2 or Scope 3 emissions, indicating a focus solely on direct emissions from its operations. This represents an increase from 2022, where emissions were approximately 44.4 billion kg CO2e, and from 2021, which recorded about 43.6 billion kg CO2e. Calpine has not set specific reduction targets or initiatives as part of its climate commitments, nor does it participate in the Science Based Targets initiative (SBTi). The absence of documented reduction targets suggests that the company may be in the early stages of formalising its climate strategy. The emissions data is not cascaded from any parent organisation, and all figures are directly reported by Calpine Corporation. The company continues to operate within the energy sector, where emissions management is critical for aligning with global climate goals.
