The Australian government should consider lowering the threshold for the Safeguard Mechanism to capture more industries as a way to help speed up the push to net zero.
That recommendation forms part of the Productivity Commission’s interim report into how Australia can improve its pursuit of net zero.
The Commission suggests dropping the Safeguard Mechanism emissions threshold for industrial facilities from 100,000 tonnes to 25,000 tonnes of carbon dioxide equivalent per year.
Under the mechanism, facilites emitting above the threshold are required to manage those excess emissions through the purchase of carbon credits or other methods.
Yet an analysis by the Institute of Public Affairs (IPA) argued the Safeguard Mechanism was a self-imposed tariff, and could cost affected facilities around $1.7 billion every year—higher than the projected cost of Trump tariffs, estimated to be $1.2 billion.
“The cost of the Safeguard Mechanism—already exceeds the cost to Australians of the Trump tariffs, which reinforces policymakers should focus on domestic policy rather than shifting blame to international events which are largely uncontrollable,” IPA Chief Economist Adam Creighton said.
It also found that 80 percent of affected facilities are involved in exporting goods.
Incorporate Net Zero into Environmental Planning
Among other recommendations from the Commission’s “Investing in Cheaper, Cleaner Energy and the Net Zero Transformation” is to amend the Environment Protection and Biodiversity Conservation (EPBC) Act 1999.“Reducing emissions from greenhouse gases is an important national priority. It comes with costs, but these can be minimised with careful policy design, freeing up resources for more productive activities and enabling gains in productivity and living standards,” the report said.
During its first term, Labor shelved its proposed Nature Positive laws, despite the reforms nearing passage in Parliament, after pressure from Western Australian Premier Roger Cook ahead of a state election.
The legislation would have expanded the powers of the federal Environmental Protection Agency to oversee environmental assessments, approve projects, and issue permits and licences—affecting sectors such as mining, recycling, waste management, and cultural and environmental preservation.
The new environment minister, Murray Watt, is now reassessing the legislation.
The report also recommends introducing national environmental standards, regional planning for renewable energy zones, and stricter statutory deadlines for project assessments in designated “go zones.”
Provide the Right Incentives
The commission said that to meet net zero targets at the lowest possible cost, governments must provide consistent and comprehensive emissions-reduction incentives.To ensure long-term grid reliability and cost efficiency, it advised governments to implement enduring market settings in the electricity sector beyond 2030. These should offer nationally consistent incentives for clean energy and embed investment signals for system reliability.
Climate Change Minister Chris Bowen recently expanded taxpayer support for clean energy through the Capacity Investment Scheme (CIS).
Streamline Transport Emissions Policy
The Australian government should also introduce a new incentive to cut heavy vehicle emissions, according to the commission.The scheme should support all viable technologies, including low-carbon liquid fuels and electric alternatives.
The Albanese government in its first term introduced several schemes to make electric vehicles (EVs) more affordable, such as the Electric Car Discount, CEFC financing, and a national EV strategy.
But with the new Vehicle Efficiency Standard (VES) now in place, the Commission says extra incentives—like tax breaks and registration discounts—should gradually be phased out.
Create a Renewable Strike Team
To fast-track high-priority renewable energy projects, the commission has recommended the Department of Climate Change and Energy set up a specialist strike team.It also proposes appointing an independent Clean Energy Coordinator-General to monitor approvals, resolve delays, and advise on renewable energy priorities.
Rate Housing Climate Resilience
The Commission has recommended a national star rating system to show how well homes can cope with climate risks like floods, fires, and heatwaves.It would build on the existing NatHERS scheme, which gives homes a star rating out of ten based on factors like construction, local climate, and how the house is positioned on the block.
The new system would also consider climate-related risks in different locations and offer simple guidance to help homeowners and builders strengthen property resilience.
Track and Improve Adaptation Policy
Finally, the commission recommended that the Climate Change Authority be legislatively tasked with monitoring and evaluating climate adaptation measures.It said this would improve accountability and ensure governments receive regular, evidence-based updates on whether current policies are working and where changes are needed.
Progress reports should be published every two years, with clear recommendations to strengthen adaptation efforts and support Australia’s resilience in a changing climate.
