by Joanne Ivancic* (Advanced Biofuels USA) First proposed in 2015, Advanced Biofuels USA’s proposal for a “Disappearing” Non-Renewable-Carbon User Fee begins: “If we’re serious about reducing climate change-causing greenhouse gases and reducing non-renewable liquid and gas use, we need serious actions.” And those actions should serve low income, high pollution areas that have suffered environmental injustices. The first steps needed are: Including the price of GHG effects in the pricing of renewable and non-renewable fuels. Committing serious money to focused renewable fuel research and infrastructure development. The simplest and fastest way to accomplishing this is adding a Non-Renewable-Carbon User Fee to the portion of liquid transportation fuels and natural gas made from non-renewable sources.
