One question asked then was how much would Australian policy reduce global temperatures? Using a simple model, and assuming that Australian greenhouse gas emissions were reduced by 5 per cent from 2000 levels by 2020 and this reduction was maintained through to 2100, the resulting global benefit would be a reduction of 0.0038 degrees in 2100.
Very large cost, very small benefit.
