The world's top 50 methane emitters: Ranks the largest global methane sources by emission flux rate. Focuses on persistent sources to prioritize high-impact mitigation. The list is updated monthly. Download the world's top 50 methane emitters list, view the monthly snapshot of the world's top 50 methane emitters, country responses and mitigation or refer to the MARS world's top 50 methane emitters data dictionary.
MARS response rate by country: Aggregated statistics on a 12-month rolling average measuring stakeholder response to MARS-notified events. Tracks the percentage of notified sources for which IMEO has received feedback from governments or operators for each country. Download response rate data or refer to the MARS response rates data dictionary.
Sources and plumes: Information on the sources of methane emissions across all sectors detected through MARS, as well as detailed information for every plume detected at each source. CSV, GeoJSON. Please refer to the MARS methane plumes and sources data dictionary for more information.

This data set provides a list of the top 50 largest and most persistent methane sources detected by satellites globally. It ranks sources by emission flux rate for those sources where persistency is high (≥ 0.4) and uncertainty is low (≤.15). The list is updated monthly.
The response rate is a metric that measures the percentage of notified emission sources for which IMEO received feedback from governments or operators compared to the total number of notified sources.
This data set provides country-level statistics on notified sources, feedback received and response rates for methane emission sources identified and notified through MARS. The list is updated monthly.
Please refer to the MARS Methane plumes and sources data dictionary and the OGMP 2.0 company factsheet data dictionary for more information.
