Australia’s use of carbon offsets is facing renewed scrutiny, with a Guardian opinion column arguing that credits should not be treated as a substitute for direct emissions reductions.
In a column published by Guardian Australia climate and environment editor Adam Morton, the focus is on Australian Carbon Credit Units (ACCUs), which are designed to represent greenhouse gas reductions or removals through approved projects.
Morton argues that offsets can support activities such as forest regeneration and methane capture, but says they have limitations when used to compensate for emissions from fossil fuels and other major industrial operations.
The column focuses on the federal safeguard mechanism, which applies to large industrial facilities and allows businesses to use carbon credits to help meet their emissions obligations. Morton argues that relying heavily on offsets can reduce the incentive for some companies to make direct cuts at their own sites.
A key issue raised is the difference between carbon stored in natural systems and carbon released by extracting and burning fossil fuels. Forests and other natural carbon stores can be affected by fire, decay and land-use changes, while fossil carbon released into the atmosphere can remain there for very long periods.
The column also points to concerns raised by research about whether some Australian carbon-credit methods deliver the level of emissions reductions claimed. Those findings have been disputed, and the Guardian column notes that the debate over the integrity of individual methods remains contested.
Morton also cites Clean Energy Regulator data showing that fossil fuel companies bought about two-thirds of the offsets sold in Australia during the last reporting year. The column links this purchasing pattern to wider questions about whether the safeguard mechanism is encouraging enough direct emissions reduction.
The discussion comes as a legislated review of the safeguard mechanism is under way. Morton argues that any changes should consider tighter emissions baselines, stronger checks on offset integrity and limits on how many credits companies can use.
For broader context on the environmental pressures facing Australia and the wider world, Australia By Aussie has previously reported on the growing pressure on Earth’s planetary boundaries.
The article is an opinion column and reflects Morton’s analysis and recommendations rather than an independent government assessment or a consensus finding on the effectiveness of every Australian carbon-credit project.
