Global consensus says that greenhouse gas emissions (GHG) have a negative effect on the environment. While interest in social responsibility has caused some corporate leaders to initiate programs to reduce their GHG unilaterally, others are waiting until imperatives force action. Many company leaders do not initiate programs until the cost-benefit becomes clear. While the cost impact associated with a unit of emission is increasing dramatically, two additional factors are motivating action. The first is the regulatory environment. The second--and potentially more powerful factor is pressure from customers, both corporate and individual. Pressures and conditions require companies around the world that source, manufacture, or distribute physical materials to determine and manage their GHG and to reduce emissions over time. This session will explore the greater urgency for responsible companies facing regulatory pressure.
