AUGUSTA, Maine (AP) — Maine environmentalists celebrated the adoption of new federal regulations that will nearly double the average gas mileage of new cars and trucks by 2025, calling them a major step toward reducing global warming while saving consumers hundreds of millions of dollars in reduced fuel costs.

‘‘Future generations may well look back on today as a decisive step toward breaking our destructive oil addiction,’’ said Emily Figdor, director of Environment Maine.
