In an earlier version of this edition of the Leaderboard, Greenpeace had penalised IBM by 5 points for its membership in the American Legislative Exchange Council (ALEC), a lobby group working to block clean energy and climate policy. IBM alerted us that they have no affiliation with ALEC at this time, so the 5 points have been restored, moving IBM from its previous 11th place overall to its current position in a tie for 8th place. We regret the error.
