NEW YORK (AP) — Many of the world’s largest companies are failing to take significant enough steps to meet their pledges to vastly reduce the impact of their greenhouse gas emissions in the decades ahead. That’s the conclusion of a new report by the NewClimate Institute, an environmental organization that works to combat global warming. Its researchers, who examined the actions of 25 companies, concluded that many of them are misleading consumers by using accounting practices that make their environmental goals relatively meaningless or are excluding key parts of their businesses in their calculations.
