The Australian government has agreed to invest almost $53 million in a north Tasmanian company that will upgrade its coal-fired kiln to burn wood “waste” and used tyres for cement manufacturing.

The Federal Minister for Climate Change, Chris Bowen, says this initiative will help decarbonise the Australian economy.

However, the science is clear: burning forest biomass, or so-called forest “waste” – which could include dead trees, understorey vegetation and fallen logs – generates large amounts of carbon emissions. It will likely also accelerate poor forest health.

The empirical evidence shows burning forest biomass to make concrete is poor climate policy, poor environmental and forest policy, and a poor use of taxpayer funds.

Why is this happening?
