The city of Montreal says it wants to do more to reduce greenhouse gases emissions.

The latest concrete step is a new bylaw to discourage vehicles from idling.

The city says it will soon be illegal to leave your car idling for more than three minutes.

An existing bylaw that's been on the books for years has not always been enforced, says the city's Alan DeSousa.

Only city inspectors could give out fines, DeSousa cited as one of the problems with applying the bylaw.

"You have a larger group of people [who will be able to enforce the bylaw] including police, parking agents…we're putting it closer to the population," he said Thursday.

The city says idling might account for about one per cent of the greenhouse gases on the island of Montreal.

Other initiatives

The city wants to do more by buying more energy-efficient vehicles for its fleet, and by using alternative fuels.

"I can't call on other people to do things if we don't make an effort, so we have taken specific measures," DeSousa said.

The city has been working on Thursday's announcement for months, and it's just a coincidence that it comes only days before a major conference in Montreal on climate change.
