Australian coal mines breach emissions caps as offsets draw fire

**TL;DR** About 80% of Australian coal mines surpassed their government‑set emissions caps in the latest reporting year, and total coal‑mine output rose 0.5% to 31.78 million tonnes CO₂‑e. Critics argue the safeguard mechanism’s reliance on land‑sector offsets allows firms to avoid real cuts.

**Context** The safeguard mechanism covers roughly 200 of Australia’s largest industrial sites, requiring them to reduce emissions intensity by 4.9% each year. Compliance is measured against baselines, and firms may meet liabilities by purchasing carbon credits generated elsewhere. Data come from the National Greenhouse and Energy Reporting (NGER) system, administered by the Department of Climate Change, Energy, the Environment and Water (DCCEEW), which mandates annual emissions reporting from facilities exceeding 100,000 tonnes CO₂‑e.

**Key Facts** Approximately 80% of coal mines emitted more than their individual limits, according to the latest NGER inventory. Total coal‑mine emissions reached 31.78 million tonnes, an increase of 0.5% from 31.63 million tonnes the previous year. Georgina Woods of Lock the Gate said the scheme’s dependence on land‑sector offsets "lets fossil fuel companies lean heavily on offsets instead of investing in reducing pollution at the source" and called it "a recipe for failure." Major buyers such as Rio Tinto and Woodside each acquired over 1 million tonnes of offsets, spending roughly $40 million apiece.

**What It Means** The modest overall rise suggests that without offsets, onsite emissions would have fallen only slightly, raising doubts about the mechanism’s ability to drive deep decarbonisation. Continued reliance on offsets may delay needed shifts to renewable energy and efficiency upgrades at mines. Watch for the government’s scheduled 2025 review of the safeguard mechanism, which could tighten offset eligibility and impose stricter baselines on coal operations.
