This Frontline investigation takes on one of the most pressing issues of the modern era: global warming. With scientists in near-universal agreement on man's role in climate change, big businesses across the planet have promised to "go green," but the question remains as to whether these commitments will yield real results. HEAT travels around the world to offer new perspectives on the politics of protecting the environment.
Description by PBS Video:
For years, big business has resisted environmental policy and stifled the debate over climate change. Now, facing pressure from governments, green groups and investors alike, big business is promising to reshape its approach to the environment, fundamentally transforming the politics of the debate. FRONTLINE producer Martin Smith travels the globe to test what big business is really doing to solve one of the most urgent issues of our time.
