Asia's fossil fuel industry readies to once again talk up carbon capture and storage (CCS) as the technology that lets us keep burning coal and gas, while still hitting our climate targets.
Alcoa and South 32's Worsley Alumina mine bauxite in WA's South-West to produce alumina that is exported to aluminium refineries.
The industry is energy-intensive mining in the jarrah forest is facing significant opposition on environmental grounds.
The US miner expects WA government approval within 12 months to destroy 75 square kilometres of jarrah forest to enable its "number one" lever to boost profits.
Alcoa will trial technology at its Wagerup alumina refinery to produce steam by renewable-powered compression instead of gas-fired heat that promises a 70% per cent emissions reduction.
If South32’s low profile coal-burning Worsley Alumina operated like Alcoa’s facilities 1.5 million tonnes of carbon emissions a year would be avoided: the same as Alcoa's Wagerup refinery.
WA's industrial greenhouse gas emissions are dominated by four products and a handful of companies, including a few that have managed to keep a low profile in the climate wars.
No deal with Alcoa has cost Adelaide Brighton 31% of its value and threatened its WA lime business that is warring with its neighbours in suburban Perth.
