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.
