Australia’s coal mines can deliver two thirds of methane cuts
Summary
The report by Ember outlines a pathway for Australia to significantly reduce annual methane emissions from coal mines by 2030. It argues that coal mine methane (CMM) mitigation is a cost-effective and rapid way to meet climate targets, potentially reducing Australia's total annual methane emissions by 18% by 2030.
Key insights
- Australia could reduce its annual methane emissions by approximately 18% by 2030 through the mitigation of coal mine methane (CMM) alone, which would represent a 77% reduction in CMM emissions.
- Mitigating methane from coal mines is significantly cheaper than mitigating agricultural methane; the average cost for coal mine mitigation is $270 AUD per tonne of methane, compared to approximately $1,200 AUD for agriculture.
- Phasing out all thermal coal mines by 2030 could reduce annual CMM emissions by 40% from 2020 levels, with a total reduction of approximately 470 thousand tonnes of methane emissions each year.
- Preventing the opening of new coal mines or the expansion of existing ones is critical, as proposed mines could increase annual CMM emissions by 50% by 2030, adding 500,000 tonnes per year.
- Implementing mitigation technologies at existing mines could reduce CMM emissions by 370,000 tonnes per year by 2030 at an estimated cost of $99.1 million AUD. This includes improving 'housekeeping' (6% reduction), extensive drainage and VAM capture at 15 gassy underground metallurgical mines (20% reduction), pre-drainage at gassy open-cut mines (8% reduction), and abandoned mine methane mitigation (3% reduction).
- There is evidence that CMM emissions are significantly underreported. The IEA estimates that reported emissions are missing 800 thousand tonnes, and satellite data shows the Hail Creek open-cut mine emits approximately 200,000 tonnes annually, which is 10 times its officially reported amount.
