Earlier this week, the Australian Conservation Foundation released an analysis comparing how much the Federal Government spent encouraging fossil fuel usage compared to how much it spent on climate change programs in recent years.

We asked the ACF for their data and then supplemented it with our own research to try to provide a longer-term take on the comparison. The ACF has compiled data on climate change programs announced in budgets going back to 1997, so we tried to collate data on all the rebates, tax expenditures and other types of spending that encourage fossil fuel use back to 1997 as well.
