Report finds credibility gaps in corporate net-zero pledges.

A report by experts from four independent research organizations has found that while a growing number of companies are pledging to cut their greenhouse gas emissions to "net zero," that goal is rarely supported by a credible plan. Less than 5% of the companies examined passed the test, with questionable claims about their environmental efforts landing a number of companies in hot water recently. The report suggests that companies should focus on achieving the biggest emissions cuts they can as soon as possible rather than using creative accounting to meet net-zero goals.
