Greenhouse 100 Index: Second Edition

The second edition of the Greenhouse 100 Index, by James K. Boyce and Michael Ash of the University of Massachusetts Amherst Economics Department and PERI, ranks U.S. industrial polluters on the basis of their emissions of greenhouse gases in 2014. According to Professor Boyce, who directs PERI’s Development, Peacebuilding, and Environment program, “The Greenhouse 100 index informs communities, consumers, and investors which large companies release the most climate pollutants into our air.  People have a right to know about corporate responsibility for global climate change. Legislators need to understand the effects of corporate behavior on their constituents.”
