Giant U.S. chemical company DuPont announced yesterday that it intends to reduce its greenhouse gas emissions by 65 percent from 1990 levels by 2010, taking “early action” before the Kyoto climate change treaty is enacted. The company also plans to hold its energy use flat and get 10 percent of its energy from renewable sources by 2010. DuPont Executive Vice Pres. Dennis Reilley urged Congress to press forward with a bill that would create incentives for companies that take “early action” against climate change, but the bill is stalled in the Senate.
