From an original membership of 11, the ranks of the Environmental Protection Agency's (EPA) Climate Leaders program—established in 2002 to provide guidance and recognition to companies developing and implementing corporate greenhouse gas reduction strategies—has swelled to 138 partners. The partners of the Climate Leaders program come from a variety of industries, including manufacturers of electrical components and lamping.

Osram Sylvania became a partner in the Climate Leaders program in July 2007 with a pledge to reduce its corporate-wide emissions of greenhouse gases. The company joins other lighting and electrical component-manufacturing Climate Leaders General Electric, Fairchild Semiconductor U.S., and Genesis Microchip. Osram Sylvania is working with EPA to establish its baseline of emissions prior to setting reduction goals. Climate leaders set greenhouse gas reduction goals to be achieved over a period of five to ten years and inventory their emissions to measure progress. To date, eight partners have achieved their greenhouse gas reduction goals.
