Leona Aglukkaq Announces New Vehicle Emissions Regulations

Canada's government is announcing new regulations to lower greenhouse gas emissions in cars and trucks that will bring the country's auto sector in line with what the United States has already announced.

Environment Minister Leona Aglukkaq is in New York for the UN Climate Summit, and will announce the federal regulations, which will extend and deepen emission cuts that are currently in place.

Aglukkaq is attending a series of climate change meetings that will culminate in a session organized by UN Secretary General Ban Ki-moon on Tuesday.

During that session, countries are expected to recommit to greenhouse gas emissions reduction targets, in order to reach a new international treaty by the end of 2015.

At an auto-sector roundtable as part of a clean-technology summit ahead of Tuesday's main meeting, Aglukkaq announced new regulations in four areas:

- Stricter fuel efficiency requirements for light passenger vehicles, which will start as soon as the old regulations expire and run until 2025. The federal government estimates that by 2025, cars will use 50 per cent less fuel than 2008 models.

- Stricter fuel efficiency for heavy-duty vehicles.

- Further cuts to allowable emissions from cars that contribute to smog, including sulphur dioxide and carbon monoxide.

- Lower amount of sulphur allowed in gasoline by as much as 80 per cent once the regulations are fully implemented.

Government leaders from more than 100 nations are attending Ban's summit Tuesday.

Prime Minister Stephen Harper will be in New York but is not attending the summit.

Harper addresses the UN General Assembly on Thursday. Aglukkaq, instead, will address the UN Climate Summit on Tuesday afternoon.
