Greenstone’s research estimates the costs and benefits of environmental quality and society’s energy choices. He has worked extensively on the Clean Air Act and examined its impacts on air quality, manufacturing activity, housing prices, and human health. He is currently engaged in large‐scale projects to estimate the economic costs of climate change and to identify efficient approaches to mitigating these costs.
