McKinsey’s Jeremy Oppenheim analyzes the impact the recent climate conference will have on businesses and economies around the globe.

In this video interview, Jeremy Oppenheim, a director in McKinsey’s London office, explains the policy shift that Copenhagen heralded as the climate change agenda moved from being a narrow issue for environmental ministries to a broad-based economic subject for heads of state. He also untangles the changes and challenges businesses and nations should expect to confront in light of the summit. McKinsey Publishing’s Tom Kiely conducted the interview.
