Still, Bauman is deadly serious (sort of) about Washington State Initiative 732, which will appear on the ballot this November, thanks to the efforts of a group that he helped assemble. If it passes, it will impose a carbon tax on fossil fuels in Washington but reduce general taxes by about the same amount. It’s designed to cut consumption of carbon-based fuels in a revenue-neutral way without putting any additional financial burden on state residents. Behind the proposal is Bauman’s notion that our current approach to taxation doesn’t make sense. We tax things that we want more of, like profits and income, and wind up getting less of those things because taxation tends to make them scarcer. Instead, we should tax things that we want less of—and, for Bauman, that means taxing fossil fuels to reduce greenhouse emissions.
