The recent increase in emissions from Australian coalmines raises serious questions about the effectiveness of the national scheme designed to cut climate pollution. New government data shows that about 80% of these coalmines exceeded their emissions limits last financial year. Though the overall rise was small—around 0.5%—it comes at a time when the Albanese government has promised significant cuts to address climate change.
The scheme in question, called the safeguard mechanism, aims to drive cleaner practices across about 200 major industrial sites. Since its overhaul three years ago, it has required facilities to reduce their emissions intensity by 4.9% annually. However, many facilities, particularly coalmines, have struggled to meet these targets directly.
For instance, total emissions from coalmines reached an estimated 31.78 million tonnes last year, up from 31.63 million tonnes. Interestingly, nearly two-thirds of these mines released more than the previous year, and rather than making direct cuts, companies often resorted to buying carbon offsets. This means they compensated for their high emissions by funding projects that reduce emissions elsewhere.
Scientists warn that this reliance on offsets is problematic. Experts, including Georgina Woods from Lock the Gate, describe it as a significant flaw. They argue that allowing companies to use offsets undermines real progress in reducing emissions at the source. Kate Dooley from the University of Melbourne echoes this sentiment, stating that Australia’s climate targets hinge on direct emissions reductions, not temporary fixes like carbon storage.
Despite claims that emissions from covered facilities are lowering, it’s important to note that only those emitting over 100,000 tonnes of CO₂ annually are included in the scheme. Thus, emissions from smaller facilities aren’t reflected in the overall data, making the actual reductions even less significant than reported.
Moreover, while companies like Rio Tinto and Woodside have spent millions on carbon credits, experts suggest this may not be a deterrent to pollution. The consultancy RepuTex indicates that significant changes in decarbonization practices are still pending in many industries due to high costs and the long lead times needed for clean technologies.
Concerns are amplified by practices where companies receive carbon credits even when emissions rise, as seen in the cases of Adani’s Carmichael mine and Glencore’s Hail Creek mine. The Albanese government maintains that the safeguard mechanism is effective, citing it as good policy. However, other agencies, like the Net Zero Commission, warn that the scheme might not drive the urgent onsite cuts needed to meet climate goals.
As the nation gears up for a review of the scheme, many believe it should undergo a comprehensive examination rather than the light touch that some expect. The conversation around these issues underscores the ongoing debate about how best to tackle climate change effectively and responsibly.
