Ford said yesterday that a team of top executives would begin looking at ways to reduce the company’s greenhouse gas emissions. Ford’s second-annual corporate citizenship report estimated that its vehicles and factories contribute about 2 percent of all such emissions caused by people. Still, Ford said it did not support the Kyoto treaty on climate change or tougher fuel-efficiency standards for vehicles. In other thrilling corporate news, Entergy Corp. yesterday became the first private power generator to agree voluntarily to cap its carbon-dioxide emissions, according to Environmental Defense. The company says it will keep emissions at current levels while increasing power production from its plants by 25 percent over the next four years.
