Environment
We have made significant progress in reducing our cementitious intensity through our lower carbon concrete
program but our alternate fuel and renewable electricity programs have been delayed

⚫ Good progress on overall on key initiatives
Renewable energy solar PPA agreement in place but
delivery delayed until late FY25
Cement intensity reduction has progressed in all regions
with strong customer engagement and supply models
improving (e.g. slag and fly ash)
Alternative fuels upgrade investment well progressed,
delays in regulatory approval process and third party project
delivery is impacting overall delivery timelines

Key initiatives
Boral commenced our alternative fuels program in 2018 to enable
18% of SWDF as a fuel replacement
We are currently investing in a chlorine bypass process upgrade to
enable up to 60% of alternative fuels
To expand our SWDF usage from 45% to 60% we require a DA
The DA application submitted in November 2021 and is still pending
and could push back our planned alternative fuel program
