DeSmog Investigation into Faulty Natural Gas Emissions Reporting Prompts Response from B.C. Government

The B.C. Ministry of Environment stands by its "implausibly low" estimate of methane leaks from the natural gas sector according to an official “information note" triggered by DeSmog's two-part article series last May.

The DeSmog investigation revealed methane leaks were likely 7 times greater than the B.C. government is reporting based on data from US studies. The real climate impacts of those leaks would be like adding at least three million cars to B.C. roads.

DeSmog's findings were subsequently confirmed by international energy experts in June. "Canada appears to have vastly underestimated fugitive emissions (leaks) from gas exploration in British Colombia [sic]," possibly because of "inadequate accounting methodology" they reported.

Their report documents studies and data from other countries showing methane leaks range between 2 and 9% of total production compared to B.C.'s reported 0.3%. This difference is "substantial" they said.

The Environment Ministry's July 22, 2013 information note to Minister Mary Polak acknowledges a "recent article referencing 'implausibly low' BC shale gas emissions was published in DeSmog Canada…." and as a result "B.C. Sustainable Energy Association and others are questioning if the natural gas to be used for LNG production is clean and if industry is operating with appropriate social license."

B.C. Gas Industry "Different" Than Rest, Says Ministry of Environment

The Ministry dismisses those questions and the evidence of under reporting by saying the gas industry in B.C. is "significantly different" and its methane leak estimates (no measurements are done) are accurate. That would make its gas industry, which is largely foreign-owned, the world's leader on controlling methane leaks.

Super, Natural B.C. indeed.

Natural gas is mostly methane. There are thousands of places where small methane leaks can occur in natural gas operations including drilling, gathering, processing and pipelines an industry expert previously told DeSmog. The industry doesn't like to call them leaks, preferring the term “fugitive emissions.” As DeSmog reported last May no one measures the leaks, not the industry, not the Ministry of the Environment nor the industry regulator, the B.C. Oil and Gas Commission.

Methane matters because it is a powerful greenhouse gas, much better at trapping heat than CO2.  Initially this heat-trapping power was considered 21 times greater than CO2 over a 100-year time period. Later this was increased to 25 times. The Intergovernmental Panel on Climate Change (IPCC) report released last September concluded that methane is 34 times better than CO2 at trapping heat on a 100 year time scale, and 84 times greater on a more climate-relevant 20 year time scale.

The Ministry of Environment continues to calculate methane using 21.

The Public Deserves Real Answers Based on Real Data

The B.C. gas industry exports 65% of its annual production to Alberta and the U.S., 15% stays in B.C. and 20% is 'lost' according government statistics (B.C.'s Natural Gas Exports). That 20% amounts to 7.4 billion cubic meters in 2010 out of a total production of 36.4 billion cubic meters  Most of this gas is not actually 'lost' but used by the industry to power equipment and pump the gas through the pipelines. What is truly lost is lost through flaring, venting and leaks of methane.

Let's assume for a minute there are no leaks or venting and that all 7.4 billion cubic meters of this 'lost' gas is used to power equipment. That would result in 14 million tonnes of CO2 emissions. (When a cubic meter of gas is burned it produces 1.9 kg of CO2 according to Environment Canada.)

However the Ministry says B.C.'s entire oil and gas sector emitted 6.2 million tonnes (Mt) in 2010 and the July 22nd information note says 10.5 million tonnes in 2011. Something doesn't add up.

These questions need real answers backed up by up-to-date, independent and measured-in-B.C. data. This information is essential for B.C. MLAs to properly debate rules for carbon pollution and taxes for dramatic expansion of gas production for liquefied natural gas (LNG) development.

Threats to our environment are often hidden from public view.
So we’ve embarked on a little experiment at The Narwhal: letting our investigative journalists loose to file as many freedom of information requests as their hearts desire.

They’ve filed more than 300 requests this year — and unearthed a veritable mountain of government documents to share with readers across Canada.

But the reality is this kind of digging takes lots of time and no small amount of money.

As many newsrooms cut staff, The Narwhal has doubled down on hiring reporters to do hard-hitting journalism — and we do it all as an independent, non-profit news organization that doesn’t run any advertising.

Will you join the growing chorus of readers who have stepped up to hold the powerful accountable?
