Guest: Chris Turner

Calgary-based author Chris Turner joins host Tim Nash on this episode of 'Responsible Investing for a Sustainable Economy' to provide some much-needed good news on the climate change front. In his latest book, "How to Be a Climate Optimist: Blueprints for a Better World," he highlights places around the globe that are making remarkable environmental progress.
