On November 23, 2009, Premier Jean Charest announced targets for reducing greenhouse gases during the United Nations Climate Change Conference in Copenhagen. Quebec will cut its emissions by 20% by the year 2020 compared to international reference of 1990. On January 14, 2010, a new law came into force to reduce greenhouse gases from automobiles which represent 40% of Quebec GHGs. This new law stipulates that car manufacturers serving the territory of Quebec must meet an emission ceiling of 187 grams of GHG/km or approximatively 7.7 L/100 km. This level must be reduced annually up to 127 grams of GHG/km or approximatively 5.3 L/100 km in 2016. These standards are as stringent as those in California (United States), according to the Government of Quebec. The provincial government plans to offer up to $8,000 rebate towards the purchase of an electric car. The government hopes that by 2020, a quarter of cars purchased in Quebec will be electric. The plan would position Quebec as a world leader in electrified transportation according to Jean Charest.
