Unreported methane emissions from coal mines could heighten risks within the coal sector and impede the decarbonization efforts of Indonesian coal companies, according to a new report by London-based energy think tank Ember.
The report analysed the emission profiles of 10 major coal-mining companies in Indonesia, which collectively produce half of the archipelago’s coal.
The report added that coal firms are overlooking planet-warming methane emissions. Methane is responsible for about one-third of warming from greenhouse gases.
Only four out of ten major companies included coal mine methane emissions in their emissions inventories.
The estimated coal mine methane emissions for the remaining six companies are as substantial as their reported emissions from fossil fuel combustion and purchased electricity combined.
The report added that currently, coal companies prioritize carbon dioxide reduction in their sustainability initiatives. However, coal mine methane remains the one emissions challenge that none of the companies assessed plans to address.

The report highlighted the importance of calculating methane emissions and said this measure would also help coal companies better understand the problem and align with national and international standards.
Additionally, coal mining companies need to factor in methane emissions when reassessing environmental and investment risks during the broader energy transition.
Diversifying their business operations will not only help mitigate these risks but also enable them to capitalize on the rapidly growing opportunities in renewable energy, offering a hopeful outlook for the future.
It added that proactively addressing methane emissions is, and will continue to be, essential for reducing the environmental and social governance risks associated with coal mining.
