Invista, the manufacturer of Antron carpet fiber, will retire 11,726,000 pounds of global warming credits to offset emissions caused by energy use at the 2003 U.S. Green Building Council (USGBC) Greenbuild International Conference and Expo in Pittsburgh, Pa., on Nov. 12-14, 2003. The credits represent a reduction from the DuPont Sabine River Plant in Orange, Tex., equivalent to 5,863 tons of carbon dioxide.

Global warming credits are awarded to companies that take action to reduce pollutant emissions. Credits can typically be sold, traded, or banked for future use. Rather than save these emission credits for future trading, Invista has chosen to donate the credits to Leonardo Academy, a non-profit organization dedicated to putting the competitive market to work on improving the environment. Through the organization's Cleaner and Greenersm program, the credits will be retired, offsetting the amount of CO2 pollution that is discharged to the atmosphere from travel, hotels, utilities, and all potential emissions connected to the conference.
