More than 150 international companies have signed on to a petition begging diplomats meeting in Bali next week to come up with policy aimed at cutting global greenhouse-gas emissions at least in half by 2050. The companies — Shell, Coca-Cola, Dupont, British Airways, Rolls Royce, and many, many, more — “urge world leaders to seize this opportunity” with “strong, early action on climate change.” The petition also stated that a push to reduce emissions would “create significant business opportunities” and a legally binding agreement “will provide business with the certainty it needs to scale up global investment in low-carbon technologies.” Apparently these businesses — comprising some 80 percent of the world’s largest companies — didn’t get the environment vs. economy memo.
