Associated Coal Mine Methane Mitigation Projects

Some coal mines have installed infrastructure which can use and/or destroy some methane emissions associated with mining. In 2024, the Global Methane Initiative reported that this mine had a mitigation project associated with it. This methodology page describes how GEM classified these projects and linked them with coal mines in the Global Coal Mine Tracker.
