Federal rules mandating that automakers double vehicles’ fuel efficiency by 2025 were finalized Tuesday, spurring  a flurry of opinions about the monumental impact of the new standard.

While supporters are calling the fuel efficiency standard a landmark boost to the environment and economy, opponents have questioned whether the goal is realistic and even dangerous.

Environment Texas, a statewide advocacy group, called the rule the nation’s single most significant effort to combat global warming.

“Future generations may well look back on today as a decisive step toward breaking our destructive oil addiction,” said Environment Texas Director Luke Metzger in a written statement.
