Tim Profeta is the founding director of the Nicholas Institute for Environmental Policy Solutions. The Nicholas Institute is part of Duke University and focuses on improving environmental policy making worldwide through objective, fact-based research in the areas of climate change, the economics of limiting carbon pollution, oceans governance and coastal management, emerging environmental markets and freshwater concerns at home and abroad.

In his role at the Nicholas Institute, Profeta has continued to use his experience on Capitol Hill to engage in climate change debates. His research has focused, specifically, on market-based approaches to environmental regulations—particularly energy and climate change policy. Other projects engage his expertise in environmental law and air pollution regulation under the Clean Air Act.

Federal Science Report Finds Human Activity Does Influence Climate Change

A draft report on the science of climate change estimates that it is “extremely likely” that more than half of the rise in temperatures over the past four decades has been caused by human activity.

Extension of California’s Cap-and-Trade Program Entails Tough Balancing Act

On Monday California Governor Jerry Brown and legislative leaders released a plan to extend through 2030 the state’s cap-and-trade program, which limits carbon emissions and requires polluters to buy allowances for greenhouse gas emissions—that is, permits to pollute.
