Hal recently gave a talk in Berlin on incentivizing clean energy development. He points out issues with the claim that a carbon price would enable the free market to solve the problem of carbon pollution, including the political difficulty of implementing a meaningful tax or cap on carbon and the challenge of split incentives (e.g. tenants usually pay energy prices, rather than architects, builders, or even owners). Hal advocates for strong, dynamic (e.g. self-tightening), technology-agnostic performance standards designed to capture 100% of the sectors they are trying to impact. Take a look at the video for all the details.
