Most modern vehicles are equipped with an automatic start-stop system that shuts off the engine when the vehicle is idling at a stoplight. According to Natural Resources Canada, these systems are effective in reducing emissions and saving money. Over a span of 10 years, the start-stop system can reduce emissions by as much as 3,450 kg (7,804 lbs.) and save the driver as much as C$2,000 (US$1,486). Despite some criticism about these systems wearing out starter systems, there is little evidence to support this claim.
