Australia's Climate Policy: Over-reliance on Carbon Offsets

Australia's climate policy faces scrutiny due to an over-reliance on carbon offsets, known as Australian Carbon Credit Units. These credits are primarily generated from projects like forest regeneration or methane capture.

However, these offsets are treated as a direct substitute for emissions cuts by major polluting industries under the safeguard mechanism. This offers flexibility but raises concerns, as naturally stored carbon is prone to release through decay or events like fires, unlike geologically stored fossil fuels.

Research suggests some Australian carbon credit methods may provide only a fraction of claimed reductions. The low price of credits, less than $40 per tonne of CO2, incentivizes polluters, including fossil fuel companies, to buy them rather than reduce their direct emissions. For instance, BHP reportedly chose to buy offsets over cutting emissions from its operations.

This reliance is problematic, as immediate and sustained direct emissions cuts are critical for mitigating climate change, with offsets serving as a supplementary strategy, not a replacement. Future reviews of the safeguard mechanism are expected to address flaws in the system.
