How green is your Volvo? Its manufacturer is happy to tell you in its recently published Environmental Product Declaration, a cradle-to-grave look at the pollution generated by the manufacturing, use and eventual dismantling of its S80 luxury sedan. "Its our judgement that consumers have a right to this kind of information," said Hans-Olov Olsson, president and chief executive of Volvo Cars of North America. "It lets people know about the environmental processes that are ongoing within the company."
