The Albanese government’s flagship climate policy will apply to fewer than two dozen heavy polluters across Victoria, including the state’s largest gas projects, refineries and metal manufacturing plants.

Australia’s 215 biggest industrial polluters will have to cut their net emissions by 30 per cent by 2030 under details of the policy revealed on Tuesday, adding binding targets to the former Coalition government’s “safeguard mechanism”.

Industrial sites that emit more than 100,000 tonnes of carbon a year are captured under the mechanism. In the 2021 financial year that applied to 212 facilities, which emitted a total of 137 million tonnes.

Victoria was home to 18, accounting for 6 million tonnes of carbon emissions – just over 4 per cent of the national total.

ExxonMobil’s Gippsland Basin gas project was the heaviest Victorian emitter on the 2021 list, followed by Viva Energy’s Geelong oil refinery, one of two plants in Australia producing petrol, diesel and LPG. ExxonMobile shut down its Altona Refinery, the fourth-biggest emitter on the list, in August 2021.

The emissions cap will also apply to the Alcoa aluminium smelter in Portland; the Qenos petrochemical plant in Altona;Beach Energy’s Lang Lang and Otway gas plants; BlueScope’s Western Port steelworks on the Mornington Peninsula; the Opal Australian Paper Maryvale Mill; Oceania Glass in Dandenong South; Melbourne Water’s Werribee sewage treatment plant; and V/Line, which operates a fleet of diesel trains.

Electricity generation accounts for half of Victoria’s annual emissions, but the state’s three remaining coal-fired power plants are not counted individually under the safeguard mechanism.

Industry groups have broadly welcomed the scheme for giving businesses certainty after years of climate policy inertia, but operators of the Victorian facilities affected said they would need more details before backing it.

Beach Energy chief executive Morné Engelbrecht said: “While there is still more detail required before Beach can fully understand any direct impacts to our business, we are already actively pursuing the policy objectives through emissions-reduction activities”.

An Alcoa spokesperson said the aluminium maker also needed more time to review the government’s plans, but the emissions-reduction pathway aligned with Alcoa’s own plan for net-zero emissions by 2050. The company welcomed the government’s support for “emissions-intensive, trade-exposed businesses”.

Export businesses can apply for grants totalling $600 million to help pay to decarbonise their operations, the government said.

A spokesman for Viva Energy said the company was still reviewing the policy and would make a submission.

An ExxonMobil spokesman said the company was reviewing the recommendations in the government’s policy. The US oil and gas giant had made progress to cut emissions by limiting fuel gas and flare usage at its Longford plants and was looking to use carbon capture and storage – a contentious technology – in the Gippsland Basin.

“Decarbonising Gippsland gas supports Australia’s transition to alternative energy sources while presenting opportunities for the Gippsland region to maintain its role as one of Australia’s significant energy hubs,” the ExxonMobil spokesman said.

Climate campaigners and the Greens have taken aim at the scheme for allowing companies to meet their emissions targets by buying carbon offsets rather than forcing them to cut pollution.

The Climate Council’s head of advocacy, Jennifer Rayner, said it would “encourage a whole bunch more tricky carbon accounting instead of the genuine transformation of these businesses that we need”.

Victoria contributes about 17 per cent of Australia’s emissions, the third-highest state behind NSW and Queensland, which are home to more carbon-intensive industries.

The Andrews government aims to cut emissions by 80 per cent compared with 2005 levels by 2035 and hit net-zero by 2045.
