KPN's emissions fell across all scopes in 2025, and it has SBTi-validated targets for net zero by 2040. Its claim of 100% renewable electricity since 2011 rests mostly on certificates, with a solar contract from 2025 and an offshore wind contract due in 2027. It calls itself climate neutral through offset certificates, and it treats water and biodiversity as not material.
