Global engine maker Cummins Inc. said that it has exceeded a 25% greenhouse gas (GHG) emissions reduction commitment as part of its involvement in the Environmental Protection Agency’s (EPA) Climate Leaders Program (CLP).

Cummins noted that CLP member companies must complete a corporate-wide inventory of their GHG emissions based on a quality management system, set aggressive GHG emissions reduction goals, and report their progress annually to the EPA.

The engine maker joined CLP in 2006 and set the goal of a 25% reduction of GHG emissions per dollar revenue from 2005 to 2010. As of year-end 2010, however, Cummins said it’s achieved a 28% reduction in GHG emissions.

“We strongly believe in the business case for climate change actions,” said John Wall, Cummins vp & CTO. “It is good business, good for our business, and it is the right thing to do. Meeting our goal not only has been good for the environment, it saves Cummins more than $20 million dollars annually.”

Ignacio Garcia, vp & chief manufacturing officer, added that Cummins’ has implemented nearly 300 energy-efficient capital projects across seven specific energy themes, with an average return on investment of 50%.

Those efforts include: making high-efficiency lighting upgrades, installing power management systems, energy efficient motors, pumps and fans, compressed air optimization, heating and cooling equipment upgrades, and energy recovery from engine test cells.
