Methane leaking from Poland’s coal mines needs more urgent action
We analysed Europe’s country-by-country methane emissions reported to the UNFCCC for 2018 and mine-by-mine emissions in Poland. Based on our findings we formulated six solutions to address this issue.
We analysed Europe’s country-by-country methane emissions reported to the
UNFCCC for 2018. We found that:
We then analysed mine-by-mine emissions in 2018 in Poland. We found that:
Coal’s climate impact is not just from burning the coal itself: like oil and gas, coal also has a problem with methane leaks. This is a problem that Poland shares with coal-mining countries, especially China and Russia. We hope that Poland leads on the development of technology and pathways to help rapidly reduce leaks at home and abroad. We are also calling for the EU methane strategy to adopt measures to quickly reduce coal mine methane in Europe, and also from abroad – especially relating to coal mined for steel-making, which will be slower to phase out.
The rest are from surface mines, including lignite, and abandoned coal mines, although it is possible that the leakage rate for abandoned mines is underestimated.
The 659 kilotonnes of methane emitted from Poland’s coal mines are equivalent to 56.7 million tonnes of carbon dioxide. This is more than Bełchatów’s CO2 emissions, which were 38.3 million tonnes in 2018. This assesses methane’s fast-acting impact over 20 years, where one tonne of methane is equivalent to 86 tonnes of CO2; even if it is assessed over 100-years when methane’s impact is reduced to the equivalent of 34 tonnes of CO2, then Poland’s coal mine methane climate impact would be 22.4 million tonnes of CO2. In this report, when we convert into CO2, we do so acknowledging the quick upfront impact of methane on climate, by using the 20-year multiplier of 86.
JSW was responsible for 50% (231 kt out of 462 kt), and PGG was responsible for 40% (186 kt). JSW is mostly mining coking coal for steel-making, whereas PGG is mostly mining thermal coal for electricity generation.
Methane leaks add 51% – over half – to the lifecycle emissions of JSW’s coal, and 22% to PGG’s coal. This is despite the fact that 43% of Polish hard coal is mined with near-zero methane emissions.
It emitted 93 kilotonnes of methane in 2018; this is equivalent to 8 million tonnes of CO2. Methane leaks more than double the lifecycle emissions of Budryk’s coal, adding 107%.
These mines were Mysłowice-Wesoła and Sośnica. The methane leaked added 73% and 52% to the lifecycle emissions respectively, calculating methane’s impact over 20 years.
This methane could be easily flared to reduce its environmental impact or, simply, sold. The value of this gas in 2018 was 110 million PLN.
As Europe’s worst performers, Poland’s coal mines need more urgent action. There are so few controls on methane, companies are even releasing it into the atmosphere after it has already been captured. JSW needs to accelerate their plan for full methane emissions reduction and PGG needs to prioritise closure of its most methane-intensive coal mines. There are also interesting opportunities to invest transition money to reduce methane leaking from closed coal mines, preserving some jobs in mining regions.
