Two slim guides have recently been published on climate change solutions, one written to CEOs on how business can profit by helping mitigate and adapt to climate change, one addressing what government policies are most promising. CWR co-host Bill Baue speaks with University of Michigan Professor Andy Hoffman, co-author with John Woody of Climate Change: What's Your Business Strategy?, published May 1 by Harvard Business Press as part of its "Memo to the CEO" series. Baue also speaks Working Assets Co-Founder Peter Barnes, author of Climate Solutions: What Works, What Doesn't, and Why--A Citizen's Guide, out recently from Chelsea Green. Plus, we hear commentary from Sierra Club Executive Director Carl Pope on the failure of the Environmental Protection Agency to regulate carbon dioxide emissions, even after being ordered to do so by the Supreme Court. Thanks to Sierra Club Radio for this commentary.
