An international energy giant has joined an alliance of companies that is promoting the development of a liquefied natural gas industry in northern British Columbia.

The British Columbia LNG Alliance said Wednesday that ExxonMobil Canada Ltd., a subsidiary of U.S.-based energy giant Exxon Mobil Corp., has become the group's seventh member, joining key international players including Chevron Canada, Shell Canada Energy, Petronas, and PetroleumBRUNEI.

The alliance said ExxonMobil has a licence to export as much as 30 million tonnes of LNG annually and the company has entered an option agreement with the City of Prince Rupert for a site at Tuck Inlet.

ExxonMobil says it's the world's largest publicly traded oil and gas company. Spokesman Richard Guerrant said the company is looking forward to working with government to develop a world-class LNG industry in Canada's west.

In October, the provincial government dropped its proposed goal of a seven per cent income tax on the province's liquefied natural gas industry to 3.5 per cent for the next two decades.
