These rankings were calculated by Canadian research and publishing firm Corporate Knights Inc., for Newsweek magazine's annual green rankings to be published Thursday.
The ranking scores companies on eight different criteria, designed to measure overall corporate environmental performance against industry peers. The measures include the use of energy, carbon, water and the generation of waste, relative to revenue. The ranking also looks at other criteria such as whether executive pay is linked to environmental goals, and whether a company has a sustainability committee on its board.
The global rankings looked at the largest publicly traded companies in the world, measured by market capitalization.
