SNIP: The methane emissions leaking from the world’s coalmines could be stoking the global climate crisis at the same rate as the shipping and aviation industries combined.

Coalmines are belching millions of tonnes of methane into the atmosphere unchecked, because policymakers have overlooked the rising climate threat, according to new research.

The International Energy Agency (IEA) estimated that the amount of methane seeping from new and disused coalmines may have reached just under 40m tonnes last year.

The potent greenhouse gas is a major concern among climate scientists because it has a far more powerful effect on global temperatures than carbon dioxide.

The global energy watchdog estimates that one tonne of methane is the climate equivalent of 30 tonnes of carbon dioxide. This would put annual coalmine emissions broadly in line with the international aviation and shipping sectors combined.

The IEA revealed its shock findings in the same report which found carbon emissions from the global energy industry had reached a new record in 2018.

Methane is also known to escape from oil and gas wells, which has prompted calls for tougher regulation of the industry to reduce the climate impact. To date, coalmines have managed to avoid similar scrutiny because of a lack of data.

The IEA said that methane leakage from coalmines would prove more difficult to tackle than the methane pollution from the oil and gas industry, and added it did not expect the situation to improve before 2040.
