Cez's reported carbon emissions
CEZ, headquartered in CZ and operating in the Electricity by nuclear sector, has demonstrated significant efforts towards climate action. In 2025, CEZ reported total emissions of approximately 27.9 billion kg CO2e. This comprised about 14.1 billion kg CO2e for Scope 1 and approximately 107,000 kg CO2e for Scope 2 (location-based). Scope 3 emissions for 2025 were reported at around 13.8 billion kg CO2e, with the largest contributors being 'use of sold products' at about 8.4 billion kg CO2e and 'fuel and energy related activities' at approximately 4.1 billion kg CO2e. In 2024, total emissions were approximately 27.3 billion kg CO2e. Scope 1 emissions were about 15.5 billion kg CO2e, and Scope 2 emissions were approximately 15,000 kg CO2e (location-based). Scope 3 emissions for 2024 totalled approximately 11.8 billion kg CO2e, with 'use of sold products' contributing about 6.2 billion kg CO2e and 'fuel and energy related activities' at approximately 4.3 billion kg CO2e. CEZ has established ambitious climate commitments, including a long-term target of achieving climate neutrality by 2040. This goal was readjusted from the previous target year of 2050. The company is also working towards a significant reduction in greenhouse gas (GHG) emissions intensity. Specific targets include reducing Scope 1 and 2 GHG emissions intensity per MWh of electricity and heat generation by 30.8% by 2025 and by 57.4% by 2030, compared to a 2019 baseline. Further targets include an 83% reduction in Scope 1 and 2 GHG intensity by 2033 and an 83% reduction per MWh by 2033 from a 2019 base year, excluding certain operations. Additionally, CEZ aims to reduce absolute Scope 3 GHG emissions from the use of sold products by 58.8% by 2033 and by 90% within the same timeframe. The company also has near-term targets to reduce NOx emissions.
