Ember Research Spotlight: satellite observations reveal coal super-emitters, but monitoring gaps persist

Satellite observations of methane plumes from coal mines increased by approximately 1,400% between 2019 and 2024, yet a significant gap remains between theoretical detectability and actual monitoring. While 71% of global coal production is located in regions with favourable conditions for detection, only 10% of hard coal production has been observed via satellite. This discrepancy is attributed to factors such as satellite overpass frequency and instrument tasking priorities. High detection rates in Canada and Poland are linked to regional prioritisation by Carbon Mapper and regulatory scrutiny under the EU Methane Regulation, whereas major producers like India, South Africa, and Australia show substantial monitoring gaps despite favourable geography.

• Satellite detections of methane plumes from coal mines grew significantly from 2019 to 2024, with the number of plumes rising from 101 to 1,509 and cumulative detected emissions increasing from 6.8 to 10.8 million kilograms per hour.
• There is a major gap between the theoretical ability to detect methane and actual observations: 71% of coal production is in areas with favourable conditions for detection, but only 10% of global hard coal production has been observed via satellite.
• Major coal producers exhibit significant monitoring gaps despite favourable viewing conditions. In South Africa and Australia, favourable conditions exist for 99.5% and 92% of production respectively, but only 7% and 20% of hard coal production have had at least one attributed plume. India has 73% of production in favourable regions but almost no publicly available detections.
• Higher detection rates in Canada and Poland exceed their theoretical favourability due to targeted monitoring and regulation. Canada's detection rate is 31% despite only 16% of mines being favourable, aided by Carbon Mapper's regional prioritisation. Poland's detection rate is 49% (with 46% favourable), driven by the EU Methane Regulation's reporting requirements and venting restrictions.
• Indonesia's detection rate is 0%, which is partly explained by the fact that only 16% of its coal production is in favourable monitoring conditions, with the rest affected by rugged terrain and persistent cloud cover.
