In the article “Maine bill would raise I-295 speed limit” (Metro, March 16), we learn that the Maine Transportation Department could be granted authority to raise the speed limit on a limited stretch of Interstate 295 from 65 to 75 miles per hour. The report on the proposed measure is another striking example of legislation apparently being considered without concern for the environment.
Since fuel efficiency decreases rapidly with higher speed, this change would increase carbon pollution. Admittedly, the increase is insignificant compared with the estimated 90 million tons of carbon dioxide that is being dumped globally into our environment each day. However, the legislation reflects a mind-set that must be reversed if we are to avoid increasing droughts, floods, hurricanes, wildfires, etc. In this and all local, state, and federal mandates involving the possibility of further pollution, the environmental impact must be among the first considerations.
