Delta Air Lines (NYSE: DAL) claimed the 44th spot for U.S. companies, leading all other airlines, in the 2016 Newsweek Green Rankings, one of the world’s foremost corporate environmental rankings. The airline also nabbed the top airline spot for global companies, ranking 85th.

“Delta people are implementing processes and systems to minimize our carbon footprint across the company,” said Christine Boucher, Delta’s Managing Director – Global Environment and Sustainability. “Our ranking improved 30 spots over last year’s U.S. performance and 40 spots globally, further validating the work we are doing to be more environmentally responsible and fuel efficient.”

Newsweek Green Rankings assesses the 500 largest publicly-traded companies in the United States and the 500 largest publicly-traded companies globally on overall environmental performance.

“In the current global business and political climate, no company can continue to ignore its environmental footprint,” said Newsweek’s Senior Editor, Elijah Wolfson. “There’s good news: Newsweek’s 2016 Green Rankings show that the world’s biggest companies are improving when it comes to energy productivity and in limiting greenhouse gas emissions.”
