Every company in Poland that operates installations covered by the EU Emissions Trading System (EU ETS) must submit an annual verified emissions report to the National Centre for Emissions Management — KoBiZE (Krajowy Ośrodek Bilansowania i Zarządzania Emisjami). Missing or incorrect reports trigger administrative penalties and, in serious cases, suspension from the ETS registry.

Key deadline: Annual KoBiZE installation reports must be submitted by 31 March each year for the previous calendar year. Free allocation applications follow a separate timetable defined by the National Allocation Plan.

What Is KoBiZE?

KoBiZE operates within the Institute of Environmental Protection — National Research Institute (IOŚ-PIB) and serves as Poland's national emissions registry. Its responsibilities include:

Who Must Report to KoBiZE?

Reporting obligations apply to three main categories of operators:

1. EU ETS Installation Operators

Any company holding a greenhouse gas emission permit for a stationary installation — including power plants, refineries, steel mills, cement works, lime producers, glass manufacturers, ceramics producers, and pulp/paper mills — must submit annual verified emissions data.

2. Aviation Operators

Airlines operating flights departing from or arriving at EU airports must report CO₂ emissions from those flights. Small emitters may benefit from simplified monitoring.

3. PRTR Reporters

Operators of facilities that exceed PRTR threshold values for specific pollutants (NOx, SO₂, CO, particulates, heavy metals, organic compounds) must report annually to the E-PRTR register via KoBiZE.

Step-by-Step: Submitting Your KoBiZE Report

  1. Gather monitoring data — Collect fuel consumption records, production data, and any continuous emissions monitoring (CEMS) data for the reporting year. All values must match your approved Monitoring, Reporting and Verification (MRV) plan.
  2. Calculate verified emissions — Apply the calculation methodology specified in your permit (Tier 1–4 for activity data; default emission factors or lab-analysed values for fuels). Document all calculation steps.
  3. Commission independent verification — An EU ETS accredited verifier must check your emissions report before submission. Allow at least 4–6 weeks for the verification process, especially for large installations.
  4. Submit via the KRUE registry — Log in to the Polish registry for ETS allowances (krue.kobize.pl), navigate to your installation, and upload the verified Annual Emissions Report (AER) in the required XML format.
  5. Surrender allowances — By 30 April, surrender EU Allowances (EUA) equal to your verified emissions from the previous year. Failure to surrender results in a €100 penalty per missing allowance plus public disclosure.

Common mistake: Submitting the report with unverified data or a verification statement from an accredited body that is not listed in the Polish accreditation register (PCA). Always verify your verifier's accreditation status before engagement.

Required Data for the Annual Emissions Report

For each source stream (fuel or process input) you must document:

Penalties for Non-Compliance

The penalties for KoBiZE/ETS non-compliance in Poland are severe:

KoBiZE and the New CBAM Regulation

Since 2024, the Carbon Border Adjustment Mechanism (CBAM) applies to imports of steel, aluminium, cement, fertilisers, electricity, and hydrogen from non-EU countries. The KoBiZE registry plays an increasingly important role here: Polish declarants filing CBAM declarations must cross-reference embedded emissions data with KoBiZE-published emission benchmarks and default values.

Note for 2026: The first annual CBAM declaration for the year 2025 must be submitted by 31 May 2026. Companies already familiar with KoBiZE reporting will find the data structures similar.

Simplifying KoBiZE Reporting

Gathering emissions data from multiple production lines, reconciling fuel delivery invoices with consumption records, and formatting everything into the KRUE XML schema is time-consuming. A dedicated reporting tool can cut preparation time significantly:
