The risks of climate change demand rapid decarbonization. We believe two interlocking reform areas for U.S. climate and environmental policy can have synergistic benefits: targeted governmental interventions to accelerate the pace of change by removing barriers to permitting, siting, building, and deploying low-carbon technologies and practices, and a border-adjusted carbon tax that pushes investments towards clean options and away from fossil fuels. In other words, we are pushing for climate change policy proposals that not only offer present solutions but also hasten the advances of the future, a combination the journalist Ezra Klein has dubbed “supply-side progressivism.”
