Quebec is passing into legislation a requirement that, beginning 2018, a certain percentage of automaker’ sales be made up of zero-emission vehicles.

Quebec’s Assemblée Nationale unanimously voted in favour of the new legislation October 26, establishing the province as a staunch proponent of electric cars and other alternatively powered vehicles, reports GreenCarReports.

The new law will establish Quebec as “the California of the North,” in that many of the details of the legislation will closely mirror the Golden State’s strict environmentally-based transportation laws.

Other U.S. states, including Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, and Vermont, have also adopted new ZEV laws.

Beginning 2018, automakers must generate ZEV credits equivalent to at least 3.5 percent of the total cars they sell within the province of Quebec, meaning some may be left scrambling to offer sufficient numbers of electric vehicles in their lineup for 2017.

Reuters quoted a Ministry of Environment spokesperson as saying that by 2020, those Quebec ZEV credits will need to match 15.5 percent of total sales, and the percentage of sales is only expected to increase from there.

Canada-wide, less than one percent of vehicles sold are ZEVs, meaning that car companies have a lot of ground to cover in Quebec between now and the 2018 deadline.

Before officially becoming law, the draft resolution for ZEV percentage sales will need to be tabled for public consultation.

If public demand doesn’t match the percentage sales requirement, automakers will have to subsidize the cost of selling ZEVs at artificially low prices by pulling money from elsewhere—presumably from the sales of conventional cars, trucks and SUVs.
