In this episode we explore what it means to put a price on carbon emissions as a tool to wring fossil fuels  out of the economy and accelerate the emerging transition to renewable energy. Guest economists describe the two methods for pricing carbon emissions: cap and trade systems and a carbon fee or carbon tax approach. They demystify terms used in the policy arena: What are externalities? What’s a market signal? Carbon offset? Emissions allowance? Border carbon adjustment? How can policy-makers address the social cost of carbon emissions to vulnerable communities, or the cost of a carbon price on households? Guests: Marc Hafstead (Resources for the Future), Yoram Bauman (Stand-Up Economist).
