A Senate bill to scrap Scope 3 emissions reporting
The Liberals and Nationals said on 13 October 2026 that they would introduce the Treasury Laws Amendment (Scrapping Scope 3) Bill 2026 in the Senate. The bill would end mandatory Scope 3 emissions reporting, which covers emissions across a company’s supply chain and from customers using its products. It would also remove Group 3 entities from mandatory sustainability reporting. The Coalition is in opposition, and its release speaks of what a future Coalition government would do.
The cost figures behind the proposal
The Coalition cites a Treasury estimate that Scope 3 emissions reporting modelling alone could cost about $245,000 per entity in the first year and more than $160,000 a year after that. It says Group 3 entities, which enter the climate reporting regime from July 2027, face estimated first-year costs of up to $70,000.
Opposition Leader Angus Taylor said it is absurd to force businesses to report on emissions they cannot control, using data they often cannot access. Deputy Opposition Leader Jane Hume said the obligations cascade through supply chains, forcing smaller businesses to give emissions information to their larger customers.
Mount Pleasant and the resources angle
The release says the bill builds on an earlier Coalition announcement that no Australian government should be able to use Scope 3 emissions from exports used overseas to delay or block a resources project. Nationals leader Matt Canavan said the High Court’s decision had already overturned the approval for the Mount Pleasant expansion, leaving future investment and jobs under a cloud of uncertainty.
What happens next for Scope 3 emissions reporting
The release gives no start date, and a bill introduced by the opposition would still have to pass Parliament. It is the Coalition’s own account and does not include a response from the Government.
