Whitehaven coal mine approval jeopardises UK's international commitments

Ember's analysis suggests the Whitehaven coal mine in Cumbria will emit 15 times more methane over its lifetime than estimated by the developer, West Cumbria Mining Limited (WCML). The report argues that WCML underestimated methane risk by ignoring official UK emission factors and overstated the feasibility of its mitigation plans, which claim a 95% destruction rate compared to an IEA benchmark of 69% for coking coal mines. Consequently, the mine could substantially increase the UK's methane emissions from fossil fuel production by 2030, potentially jeopardising the UK's targets under the Global Methane Pledge.

• The Whitehaven coal mine is projected to emit 15 times more methane over its lifetime than the developer's estimates when using official National Atmospheric Emissions Inventory (NAEI) factors and IEA mitigation assumptions. This figure rises to 45 times the estimate if no mitigation is implemented.
• The developer, West Cumbria Mining Limited (WCML), estimated methane emissions based on core samples from depths of 400-540m, which Ember argues is an inappropriate methodology because it ignores methane in adjacent strata. Using the NAEI emission factor instead of WCML's estimates results in a 3.5-fold increase in unmitigated lifetime emissions.
• WCML claims it will destroy over 95% of produced methane, but the International Energy Agency (IEA) identifies 69% as a realistic figure for underground coking coal mines. Ember notes that the proposed Ventilation Air Methane (VAM) destruction technology is niche, with only four known global operators.
• The mine's emissions could significantly impact the UK's 2030 methane profile. While WCML estimates an impact of 0.3 kilotonnes, Ember calculates the mine would produce 12 kilotonnes in 2030 (more than half of other sources), or up to 39 kilotonnes if unmitigated, which would nearly triple the UK's total methane emissions from oil, gas, and coal production that year.
• The approval of the mine may cause the UK to fail its commitments under the Global Methane Pledge, which aims to reduce methane emissions by at least 30% from 2020 levels by 2030, and the Joint Declaration from Energy Importers and Exporters on Reducing Greenhouse Gas Emissions from Fossil Fuels.
