Queensland Coal Mine’s Methane Emissions Could Be Eight Times Higher Than Reported

Methane Emissions Underestimated

A new UN-backed study reveals that methane emissions from Glencore's Hail Creek coal mine in Queensland may be up to eight times higher than reported. Researchers from UNSW measured methane plumes in 2023, discovering significant discrepancies from the official figures reported by Glencore.

Flawed Reporting Methods

The current practice of estimating emissions based on state-wide emission factors has proven unreliable. Experts like Dr. Stephen Harris from UNSW advocate for mine-specific coal gas content modeling for accurate reporting. Methane, over a 20-year period, is 80 times more potent than carbon dioxide as a greenhouse gas, making accurate tracking crucial for emission reduction.

Global and Local Pressure

Australia pledged to cut methane emissions by 30% from 2020 levels by 2030 under the Global Methane Pledge, yet actual emissions remain uncertain. From July 2025, the government will require site-specific sampling for more precise tracking. Global organizations like Carbon Mapper and local agencies are increasingly monitoring methane levels through advanced technologies like satellites, aircraft, and handheld devices.

Impact and Accountability

Accurate methane monitoring could push coal mines to adopt better practices and help Australia meet its emission targets. Misreporting methane not only undermines environmental efforts but also impacts the country’s global commitments.
