Premier John Horgan鈥檚 off to Asia for his first trade mission this week, to carry on the B.C. Liberal government鈥檚 effort to promote B.C. tourist destinations, lumber and natural gas.

As Horgan and his team boarded a plane to head for China, South Korea and Japan, the latest threat of the minority NDP government鈥檚 junior partner was ringing in their ears.

鈥淟est there be any doubt, let me be perfectly clear,鈥� B.C. Green Party leader Andrew Weaver announced in a Donald Trump-style Twitter message last week. 鈥淣DP government will fall in non-confidence if after all that has happened it continues to pursue LNG folly.鈥�

For further Trumpian emphasis, Weaver added a hashtag, #LineInTheSand. He returned to Twitter on Friday to pronounce that judging from his email, 鈥渕any, many thousands鈥� of B.C. NDP voters feel 鈥渂etrayed鈥� by Horgan鈥檚 plan to meet with liquefied natural gas investors in Asia.

That鈥檚 a lot of emails from people who supposedly voted for the NDP last year because they believed Horgan鈥檚 team opposed the export of LNG. They don鈥檛, at least since the energy-savvy Horgan took over as party leader in 2014.

Yes, the NDP voted against a generous corporate tax structure put together by Christy Clark, Rich Coleman and the rest of the B.C. Liberal government that worked tirelessly to get the industry off the ground. It was seldom reported by city media, but Horgan said it repeatedly at the time: they were not voting against an LNG industry, only the terms of selling the resource offshore.

Yes, Horgan repeated time and time again that he wanted a scientific review of hydraulic fracturing, the deep shale gas extraction technique developed in Texas and used safely in B.C. for 50 years. He鈥檒l go ahead with that, but as with Site C, when the study is done it will confirm as many other studies have that shale gas wells, like hydro dams, are proven technologies with enormous benefits.

Yes, after forming a minority government, Horgan gleefully followed through with this campaign promise to empty Clark鈥檚 LNG 鈥渇antasy fund鈥� and use it to pay for cancelling Metro Vancouver bridge tolls for the next couple of years. In 2016, Clark directed then-finance minister Mike de Jong to take $100 million out of a growing surplus from your provincial tax payments, to create a long-promised LNG 鈥減rosperity fund,鈥� before B.C. had a shovel in the ground for a large-scale LNG plant or related pipeline.

That pre-election stunt was a sequel to Clark鈥檚 biggest-ever promise, in the 2013 election, that the LNG industry was going to pay off the province鈥檚 debt.

Of course Weaver鈥檚 latest threat is also a stunt, like his switch from supporting to opposing the Site C hydroelectric dam in northeastern B.C. Once again, he is throwing a big chunk of raw tofu to his political base, to prevent himself from being buried under hurled organic carrots from the root cellars of Vancouver Island.

Weaver cites B.C.鈥檚 greenhouse gas emission targets, which would never be met if large-scale plants burned gas to compress and cool LNG for shipping in tankers. Those targets won鈥檛 be met anyway, as the latest emissions data released in December show. Greenhouse gas emissions have continued to rise with population growth, dipping only during the harsh recession of 2008-09, despite the carbon tax we鈥檝e been paying in the past decade.

U.S. greenhouse gas emissions fell during the same period because they substituted shale gas for coal. They鈥檝e converted former LNG import terminals to export, and like Clark, Horgan has understood this.
