New satellite analysis indicates that several Polish coal mines may have continued venting methane in 2025 despite a ban under the EU Methane Regulation that took effect in January of that year. The findings raise concerns about enforcement gaps and the absence of penalty frameworks in Poland, the EU’s largest coal methane emitter.
According to analysis cited in the report, 96% of methane plumes detected over onshore European energy infrastructure in 2025 were traced to Polish coal mines, making them the most frequent fossil fuel methane super-emitters in the bloc. Out of 22 coal mine drainage systems examined in Poland, five were observed venting methane during the year, even though routine venting from drainage systems has been prohibited since January 2025.
The EU Methane Regulation requires operators to either utilize captured methane or flare it with at least 99% destruction efficiency. Venting is permitted only in cases of emergency, malfunction, or unavoidable maintenance, and operators must notify competent authorities within 48 hours. However, no national penalty framework has yet been adopted in Poland, despite a deadline of 5 August 2025 for Member States to define sanctions.
Methane is a potent greenhouse gas, and coal remains the largest source of fossil methane emissions in the EU energy sector. According to UNFCCC data, EU coal mining emitted 783.6 thousand tonnes of methane in 2023, accounting for around 60% of energy-sector methane emissions. The International Energy Agency estimates that 62% of the EU’s coal mine methane emissions could be technically abated by 2030, with the vast majority originating in Poland.
Satellite observations detected emission rates ranging from roughly 120 kg per hour to 7,560 kg per hour, with 19 plumes exceeding 2,000 kg per hour. Coking coal mines were responsible for most of the detected events, despite representing a smaller share of overall hard coal production. Analysts argue this highlights the need for stricter methane reduction targets for coking coal operations.
The report also estimates that methane reportedly vented from Polish drainage systems in 2024, if captured and used, could have provided enough energy to meet roughly one week of heating demand for approximately 14.5 million Polish households. Polish coal mines reportedly utilized 70% of captured drainage methane in 2024, while 57,000 tonnes went unused and were emitted into the atmosphere.
Experts stress that the effectiveness of the EU Methane Regulation depends on enforcement, independent emissions verification, and the introduction of dissuasive penalties. Recommendations include harmonized verification standards, combining satellite monitoring with on-site inspections, and setting meaningful penalty levels to incentivize compliance.
Without these measures, observers warn, the regulation risks falling short of delivering the significant methane reductions required to meet EU climate objectives.
