Coal traps methane over millions of years. Mining releases it, and over 20 years, that methane warms the planet about 80 times more than CO2. Coal mining releases roughly as much methane globally as the gas sector.
For steel, it is no footnote. Methane released by coal mining adds around 27% to steel’s 20-year climate impact, and at the gassiest mines can double a blast furnace’s emission intensity. Most of it is neither measured nor governed.
Japan illustrates the gap. It built buyer-led methane disclosure for its gas imports through CLEAN, but has not extended it to coal – even though the coal arriving at its blast-furnace mills in 2024 carried an estimated 308 kt of methane, 4.6 times the country’s entire reported domestic energy-sector methane.
Ahead of Ember’s report on 1 October, this 30-minute webinar sets out the findings, then hears from three speakers on the data, the investor case, and what moving first would look like for Japan.
The session is in English; Japanese summaries will be posted in the chat, and the recording will be shared with Japanese subtitles.
