While your article on methane (Weatherwatch, 9 June) rightly emphasised the importance of methane reduction, it overlooked a significant source of global emissions: coalmines.
Coal mining generates as much methane annually as the oil or gas sectors, yet this fact is often ignored. It is crucial that the UK does not turn a blind eye, especially in light of the new Cumbria mine, which risks undermining the commitment to the global methane pledge.
Australia, my home country, also faces a significant coalmine methane problem. Besides burping cows, coalmines are the next largest source of methane emissions. Although the Albanese government is exploring how to regulate these, it has continued to approve new coalmines.
One of the reasons that coalmines fly under the radar of journalists and others is that emissions from coalmines are underreported. While satellites have helped uncover major leaks, the full scale of the problem remains unclear. However, there are proven solutions to capture methane from coalmines, which not only mitigate emissions but can also provide a valuable fuel source.
According to the International Energy Agency, methane emissions from across the energy sector need to decrease by 75% by 2030 to align with the 1.5C climate target.
To achieve such swift reductions, we must halt new coalmine expansion, implement best practice mitigation at existing mines, and plan the coordinated closure of coalmines globally.
It is imperative that we maintain a laser focus on the coal mining sector. By solely scrutinising oil, gas, farming and waste, we allow a major culprit to evade accountability.
