Poland: annual report to the national GHG/emissions database (KOBiZE) due by end of February
Date note: Gemini candidate audit (2026-09-08), confidence: uncertain. The end-of-February deadline and Art. 7 legal basis are well documented in Polish environmental-compliance practice, but kobize.pl and isap fetches this session returned only navigation content, not the specific deadline/scope text, so this could not be independently re-confirmed against primary-source text.
Every year in February, due by the 31st. · Day 31 clamps to the last day of February. Applicability depends on operating a reportable emission source (e.g. company vehicles, boilers) - confirm scope for the specific fleet/equipment before relying on this.
What changes
Entities operating an installation or other source that emits gases or other substances into the air (including company vehicle fleets and heating/generator sources above minimal thresholds) must report their prior-year emissions to KOBiZE's national database (Krajowa baza o emisjach) by the end of February.
Who is affected
Businesses operating emission sources in Poland - in practice this reaches far beyond heavy industry, since it covers company vehicle fleets and building heating/generator equipment above minor thresholds, making it a commonly overlooked obligation for ordinary office-based companies.
Sizes: micro, small, medium, large · Sectors: All sectors
What to do
Inventory emission sources (vehicles, boilers, generators, etc.) used during the prior calendar year, register in the KOBiZE database if not already registered, and submit the annual report by the end of February.

Penalty
Liability for an offence against the environment (wykroczenie) under the Act on the greenhouse gas emissions management system.
