Carbon footprint of B.C. LNG boom could rival Alberta’s oilsands

This month, provincial MLAs are preparing for the upcoming legislative session, in which they will debate rules for carbon pollution and taxes for liquefied natural gas (LNG) development.
The connection between LNG development and carbon pollution is significant. And just how the government chooses to manage both issues will have serious long-term implications for the province, and the country.
Last year, Minister of Natural Gas Development Rich Coleman was asked on CBC’s Early Edition what B.C.’s LNG plans could mean for the province’s climate targets. His response: “Meeting our goals will be a challenge.”
If you’re wondering how big that challenge may be, there are two things you should know. The first is that carbon pollution from this industry could be extremely large, nearly as much as the oilsands in Alberta produce. The other is that B.C. can choose to make the impact much smaller.
The B.C. government is investing time and resources in promoting extensive LNG development. In order to meet their annual revenue hopes of more than $4 billion, the province will need to export four to six trillion cubic feet of shale gas per year by 2020. Producing that much gas would require five to seven LNG facilities and over 10,000 wells with the accompanying network of roads, pipelines, compressors and gas processing plants.
The Pembina Institute estimates that even the lower end of that development scenario would produce a staggering 73 million tonnes of carbon pollution per year by 2020. For comparison, the oilsands are currently Canada’s fastest-growing source of climate pollution — but by 2020, B.C.’s LNG plans would produce three-quarters as much carbon pollution if development proceeds as hoped.
For a province often cited as one of the greenest in Canada, it’s a profound disconnect.
Digging into the numbers
The carbon pollution considered here refers to LNG development in B.C. This includes pollution from extracting and processing the natural gas, likely from shale gas fields in northeastern B.C., transporting the gas to the LNG facilities on the coast, then liquefying and storing the LNG until it is loaded onto LNG carriers (tankers). This doesn’t include carbon pollution generated from burning this gas in Asia, which could produce more than 200 million additional tonnes of carbon pollution per year.
Producing 73 million tonnes or more of carbon pollution from a single industry in B.C. means the province will miss its legally binding target for carbon reductions. The law requires the annual carbon pollution from all activities (transportation, buildings, agriculture, forestry and other industry) to be below 43 million tonnes by 2020, and below 13 million tonnes by 2050.
The B.C. government could choose to alter or ignore the carbon reduction targets, as other governments have done, or add in special accounting for LNG. But these targets represent B.C.’s commitment to contribute to global climate solutions. And the evidence is mounting of the real-world impacts that repeatedly missing reduction targets can have. For B.C., the impacts of climate change include declining fisheries, flooded coastal communities and increasingly vulnerable forests.
Fortunately, walking away from B.C.’s climate commitments isn’t the only option. Decisions made about LNG development in 2014 could put B.C. on a lower-carbon development path.
