If you thought the 55mph limit was bad, brace yourself. A study by Dutch consulting firm CE Delft claims that reducing the speed limit to 50mph will cut carbon emissions by as much as 30%.
A reduction in the speed limit is a polarizing issue, with some people doubtlessly in favor of such a move, which would result in less fuel being burned and fewer cars on the road. However, CE Delft stressed that the 50 mph speed limit would be most effective in the Netherlands, as more people would walk, bike or take public transit – options that aren’t always available in the United States. The spread out, suburban lifestyle we have here is just not conducive to this kind of change.
