This event is organised by the Harvard Project on Climate Agreements.
It will take place at COP27 at the Pavilion of the International Emissions Trading Association (IETA). 

Some sixty jurisdictions worldwide – including both national and subnational governments – have adopted carbon-pricing policies, largely cap-and-trade systems or carbon taxes. Very few of these policies, however, match the economist’s ideal – an upstream, economy-wide emissions-trading or carbon-tax system (with specific rebate mechanisms for revenue). For example, China’s nationwide pricing system is an intensity-based tradable performance standard – indeed, a complex set of tradable performance standards for various sectors and subsectors. Most emissions trading systems include, to varying degrees, price collars, rendering them, effectively, ETS-tax hybrids. Economists and political scientists are examining the reasons why such systems have been adopted, and policy makers in the United States (and elsewhere) are beginning to consider how some features of pricing systems might be incorporated into non-pricing policies, thus reducing costs, given the apparent political difficulty of enacting carbon-pricing legislation.

This panel will explore these and other advanced and timely topics in carbon pricing. Robert Stavins, A.J. Meyer Professor of Energy and Economic Development at Harvard Kennedy School and Director, Harvard Project on Climate Agreements, will moderate the discussion.
