CEEPR faculty affiliate Michael Greenstone was cited in a New York Times article on the potential impacts of abundant natural gas on the environment. Acknowledging the rapid pace of innovation in fossil fuel extraction methods, he cautions that it may eventually become necessary to tap accessible reserves if carbon emissions are to be limited, something for which there is not much precedent. The article goes on to explore methane emissions from unconventional oil and gas wells, and unintended spillover effects on nuclear generation and investment in renewable energy.
