Sustainability in CEZ Group

We met the target to reduce greenhouse gas emissions in line with the Paris Agreement “well below 2 degrees Celsius” from 0.38 t CO₂e/MWh in 2019 to 0.26 t CO₂e/MWh in 2025, thus reducing to 0.24 t CO₂e/MWh. We met the target to reduce NO_X emissions from 23 kt in 2019 to 13 kt in 2025 and SO₂ emissions from 21 kt in 2019 to 6.5 kt in 2025, thus reducing NO_X emissions and SO2 emissions to 10 kt and 4 kt, respectively.

In 2025, we shut down 600 MWe of coal-fired generating units in Dětmarovice and we put a gas boiler into operation, which is to be supplemented with a biomass boiler and cogeneration units. We are preparing the construction of small modular reactors (SMRs) in Temelín and Tušimice, WtE in Mělník, and PPC in Mělník, Ledvice, Prunéřov, and Počerady.

The Dukovany and Temelín nuclear power plants generated 32 TWh of electricity safely and emission-free, creating the basis for meeting another long-term target of VISION 2030 – Clean Energy of Tomorrow.

The implemented projects saved 250,000 t CO₂e for ČEZ ESCO clients in 2025. The total savings in all ČEZ ESCO projects to date reach over 6 million t CO₂e.

CEZ employees, together with the ČEZ Foundation, raised CZK 9.8 million for people in difficult life situations. 2,231 employees contributed, supporting 134 people. The ČEZ Foundation app EPP – Move to Help celebrated its 10th anniversary. In 2025, users rode or walked 6.6 million km and distributed CZK 53.7 million among 562 projects, the highest number of projects supported in a single year since the app was created.

ČEZ Distribuce connected almost 18,000 PV plants with installed capacity of 491.6 MW. In total, 157,725 PV plants with a capacity of over 3 GW are connected to our distribution grid. Almost 88% of installations are equipped with battery storage.

About 16,000 young people voted in the survey, and CEZ Group has held the title of the most desirable employer for the sixth year in a row.

As part of corporate volunteering, CEZ Group employees worked 11,070 hours on 337 projects, supported organizations with more than CZK 2.5 million at Easter and Advent markets and fundraisers, and donated 118.37 l of blood directly at their workplace.

We published our first ESRS/CSRD Sustainability Report, which was independently audited and fully integrated into the 2024 Annual Financial Report. The report was prepared with maximum transparency and clearly presents our sustainability strategy, including a transition plan linking VISION 2030, specific targets, and actions. CEZ Group received the ESG Transparency Award 2025, awarded by the international market research organization EUPD Research.

We became the absolute winner of the National Award of the Czech Republic for Social Responsibility and Sustainable Development. S&P Global moved CEZ Group up 9 points to a total score of 62 out of 100. CDP awarded us with an A- rating in the Climate category.

We continuously use management system certification pursuant to ISO 9001, 14001, 27001, 37001, 45001, and 50001 or accreditation from the Czech Accreditation Institute pursuant to ISO 17025 or 17020 and other standards for conformity assessment.

Fuel assemblies from Westinghouse were delivered to the Temelín and Dukovany nuclear power plants.
