Whitehaven coal mine approval jeopardises UK’s international commitments

An analysis by Ember argues that the approval of the Whitehaven coal mine in Cumbria jeopardises the United Kingdom's international climate commitments, specifically the Global Methane Pledge. The report claims that the developer, West Cumbria Mining Limited (WCML), significantly understated expected methane emissions and overstated the potential for mitigation, leading to a total methane impact that could be 15 times greater than estimated.

• The Whitehaven coal mine's approval is viewed as a threat to the United Kingdom's commitments under the Global Methane Pledge, which aims to reduce global methane emissions by 30% by 2030, as well as other international climate agreements.
• Ember asserts that the developer, West Cumbria Mining Limited (WCML), understated unmitigated lifetime methane emissions by 3.5 times. This is because the developer used estimates from core samples at depths of 400-540m rather than the official National Atmospheric Emissions Inventory (NAEI) emission factors, which estimate 21 cubic metres of methane per tonne of coal produced compared to WCML's estimate of 3-7 cubic metres.
• The report claims that WCML's methane mitigation targets are unrealistic. While WCML states it will destroy over 95% of produced methane, Ember cites International Energy Agency (IEA) analysis suggesting that 69% is a more realistic figure for an underground coking coal mine.
• The total lifetime methane impact of the mine is estimated by Ember to be 15 times higher than WCML's estimates. This calculation combines the use of NAEI emission factors and IEA mitigation assumptions. Without any mitigation, the impact would be 41 times higher than WCML's estimates.
• Ember highlights concerns regarding the technology for Ventilation Air Methane (VAM) destruction. The report notes that Renewable Thermal Oxidisers are niche technologies with only four known global operations (three in China and one in the US). It cites the US-based Marshall Mine, which reported emitting over 8 million tonnes of CO2 equivalent of methane between 2014 and 2017, effectively destroying only 12% of its methane.
• The report estimates that by 2030, the mine could produce 12 kilotonnes of methane (using NAEI and IEA figures), which is more than half of the 22 kilotonnes of methane from other UK oil, gas, and coal production sources. If no mitigation is implemented, this could rise to 39 kilotonnes, nearly tripling the UK's total emissions from those sectors in 2030.
