Polish banks’ reported Scope 3 emissions rose by about 6% year on year, even as they disclosed fuller carbon footprints under the CSRD, according to Instrat’s analysis published on 29 October 2026. The organisation examined 24 Warsaw-listed financial companies, including 10 banks.
Instrat found that the share of WIG140 financial companies reporting full Scope 3 emissions rose from 18% in 2023 to 71% in 2025. Instrat said all banks and insurers in its analysis disclosed their full carbon footprints, although six of the 24 companies still reported no emissions.
Instrat links the rise at Poland’s largest bank to corporate loans and calculation data.
Instrat said reported group-level Scope 3 emissions for the financial sector rose 3.4% year on year to 134 million tonnes of CO₂e. Instrat said PKO BP’s reported Scope 3 emissions rose 18% to 29.8 million tonnes. Instrat attributed the increase in financed emissions at Poland’s largest bank primarily to a 3.3-million-tonne rise associated with corporate loans and an increase in the share of actual data used in calculations, from 39% to 57%. Instrat said the share of actual data used to calculate financed emissions at Poland’s largest bank rose from 39% to 57%.
Instrat cautioned that Scope 3 figures are not yet fully comparable across companies. Banks attribute changes in reported emissions to shifts in portfolio composition and improvements in calculation methods, Instrat said. The scale of the portfolio footprint remains clear in its analysis: among banks, portfolio emissions were 949 times their operational emissions in 2025.
Four of the 10 banks have set measurable sectoral targets for 2030, according to Instrat. Instrat said six banks declare a climate-neutrality or net-zero goal by 2050, while ING and Santander use reference pathways rather than portfolio targets in their transition plans.
