Hawaii Lawmakers are pushing a broad Carbon Dioxide Tax SB3150

In addition to the gasoline taxes they already pay, Hawaii motorists may soon be hit with a tax on vehicles’ carbon-dioxide emissions.

Senate Bill 3150 (SB 3150) would amend Hawaii’s 2010 Environmental Response, Energy, and Food Security Tax, which imposes a tax of $1.05 per barrel of oil imported into the state to fund environmental initiatives, to tie the tax to carbon dioxide emissions. The bill would replace the current per-barrel tax with a $40 per metric ton tax on carbon dioxide emissions in 2021, incrementally increasing the tax rate in stages to reach a price of $80 per metric ton by 2030.
