International comparisons of gas flaring among top oil producers
Canada contributed just 0.7% of the global amount of gas flaring despite being the world’s fourth-largest oil producer
By Ven Venkatachalam and Lennie Kaplan
This Fact Sheet analyzes the upstream oil industry’s record on flaring in Canada relative to other top oil-producing countries. Gas flaring is the burning off of the natural gas that is generated in the process of oil extraction and production. Flaring is relevant because it is a source of greenhouse gas emissions (GHGs) (see Appendix).
In 2022, 138,549 million cubic meters (m3) (or 139 billion cubic meters (bcm)) of flared gases were emitted worldwide, creating 350 million tonnes of CO2 emissions annually. Canada is a significant oil producer; it has the third-largest proven crude oil reserves and is the fourthlargest crude oil producer in the world (Natural Resources Canada, undated), and so contributes to flaring.
Flaring comparisons
This Fact Sheet uses World Bank data to provide international comparisons of flaring. It also draws on U.S. Energy Information Administration (EIA) crude oil production data to compare flaring among the top 10 crude oil producing countries.
Table 1 shows gas flaring volumes in 2012 and 2022. In absolute terms, Russia recorded more flaring than any other country at 25,495 million m3 (25.4 bcm) in 2022, which was 1,628 million m3 (7 per cent) higher than in 2012.
The four countries that are the top GHG emitters through flaring (Russia, Iraq, Iran, and Algeria) accounted for 50 per cent of global gas flaring in 2022.
At 945 million m3, Canada was the eighth lowest flarer in 2022 (23rd spot out of the top 30 countries). It decreased its flaring emissions by 320 million m3 from the 2012 level of 1,264 million m3, a 25 per cent drop.
In 2022, Canada contributed just 0.7 per cent of the global amount of gas flaring despite being the world’s fourth largest oil producer (see Table 1).

Flaring declined worldwide between 2012 and 2022
Figure 1 shows the change in flaring volumes between 2012 and 2022. Nine countries flared more in 2022 than in 2012, while 21 countries flared less. In the last decade, the global flaring volume decreased by 3 per cent.
- The three countries that most significantly increased flaring between 2012 and 2022 were the Republic of the Congo (65 per cent), Iran (56 per cent), and Iraq (41 per cent).
- The three countries that most significantly decreased flaring between 2012 and 2022 were Uzbekistan (-76 per cent), Columbia (-75 per cent) and Kazakhstan (-74 per cent).
- As noted earlier, flaring fell by 25 per cent in Canada between 2012 and 2022.

Comparing flaring to increased production
The decreases in flaring in Canada between 2012 and 2022 shown in Table 1 and Figure 1 understate the magnitude of the decline in flaring in the country. That is because Canada’s crude oil production increased by 45 per cent in that period, even as absolute flaring decreased by 25 per cent (see Table 2).
Canada compares very favourably with the United States, which increased crude oil production by 82 per cent and decreased flaring by 16 per cent.

Largest oil producers and flaring intensity
To fully grasp how much more effective Canada has been than many other oil producers in reducing flaring, Table 3 compares both flaring intensity (gas flared per unit of oil production) and crude oil production among the top 10 oil producing countries (which account for 73 per cent of the world oil production).
Canada is the fourth-largest producer of crude oil, and its gas flaring intensity declined by 48 per cenft between 2012 and 2022. Four of the top 10 oil producers witnessed their flaring intensity increase between 2012 and 2022.

Conclusion
Gas flaring contributes to greenhouse gas emissions. However, it is possible for countries to both increase their oil production and still reduce flaring. Canada is one noteworthy example of a country that has significantly reduced flaring not only compared to its increased production of crude oil, but also in absolute terms.

Background
Flaring and venting are two ways in which an oil or natural gas producer can dispose of waste gases. Venting is the intentional controlled release of uncombusted gases directly to the atmosphere, and flaring is combusting natural gas or gas derived from petroleum in order to dispose of it.¹ As Matthew R. Johnson and Adam R. Coderre noted in their 2012 paper on the subject, flaring in the petroleum industry generally falls within three broad categories:
- Emergency flaring (large, unplanned, and very short-duration releases, typically at larger downstream facilities or off-shore platforms);
- Process flaring (intermittent large or small releases that may last for a few hours or a few days as occurs in the upstream industry during well-test flaring to assess the size of a reservoir or at a downstream plant during a planned process blowdown); and
- Production flaring (may occur continuously for years while oil is being produced).
To track GHGs from flaring and venting, Environment Canada (2016) defines such emissions as:
- Fugitive emissions: Unintentional releases from venting, flaring, or leakage of gases from fossil fuel production and processing, iron and steel coke oven batteries, or CO2 capture, transport, injection, and storage infrastructure.
- Flaring emissions: Controlled releases of gases from industrial activities from the combustion of a gas or liquid stream produced at a facility, the purpose of which is not to produce useful heat or work. This includes releases from waste petroleum incineration, hazardous emission prevention systems, well testing, natural gas gathering systems, natural gas processing plant operations, crude oil production, pipeline operations, petroleum refining, chemical fertilizer production, and steel production.
- Venting emissions: Controlled releases of a process or waste gas, including releases of CO2 associated with carbon capture, transport, injection, and storage; from hydrogen production associated with fossil fuel production and processing; of casing gas; of gases associated with a liquid or a solution gas; of treater, stabilizer, or dehydrator off-gas; of blanket gases; from pneumatic devices that use natural gas as a driver; from compressor start-ups, pipelines, and other blowdowns; and from metering and regulation station control loops.
1. Many provinces regulate flaring and venting including Alberta (Directive 060) British Columbia (Flaring and Venting Reduction Guideline), and Saskatchewan (S-10 and S-20). Newfoundland & Labrador also has regulations that govern offshore flaring.

Alberta
The case for expanding Canada’s energy exports
From the Canadian Energy Centre
For Canada, the path to a stronger economy — and stronger global influence — runs through energy.
That’s the view of David Detomasi, a professor at the Smith School of Business at Queen’s University.
Detomasi, author of Profits and Power: Navigating the Politics and Geopolitics of Oil, argues that there is a moral case for developing Canada’s energy, both for Canadians and the world.
CEC: What does being an energy superpower mean to you?
DD: It means Canada is strong enough to affect the system as a whole by its choices.
There is something really valuable about Canada’s — and Alberta’s — way of producing carbon energy that goes beyond just the monetary rewards.
CEC: You talk about the moral case for developing Canada’s energy. What do you mean?
DD: I think the default assumption in public rhetoric is that the environmental movement is the only voice speaking for the moral betterment of the world. That needs to be challenged.
That public rhetoric is that the act of cultivating a powerful, effective economic engine is somehow wrong or bad, and that efforts to create wealth are somehow morally tainted.
I think that’s dead wrong. Economic growth is morally good, and we should foster it.
Economic growth generates money, and you can’t do anything you want to do in social expenditures without that engine.
Economic growth is critical to doing all the other things we want to do as Canadians, like having a publicly funded health care system or providing transfer payments to less well-off provinces.
Over the last 10 years, many people in Canada came to equate moral leadership with getting off of oil and gas as quickly as possible. I think that is a mistake, and far too narrow.
Instead, I think moral leadership means you play that game, you play it well, and you do it in our interest, in the Canadian way.
We need a solid base of economic prosperity in this country first, and then we can help others.
CEC: Why is it important to expand Canada’s energy trade?
DD: Canada is, and has always been, a trading nation, because we’ve got a lot of geography and not that many people.
If we don’t trade what we have with the outside world, we aren’t going to be able to develop economically, because we don’t have the internal size and capacity.
Historically, most of that trade has been with the United States. Geography and history mean it will always be our primary trade partner.
But the United States clearly can be an unreliable partner. Free and open trade matters more to Canada than it does to the U.S. Indeed, a big chunk of the American people is skeptical of participating in a global trading system.
As the United States perhaps withdraws from the international trading and investment system, there’s room for Canada to reinforce it in places where we can use our resource advantages to build new, stronger relationships.
One of these is Europe, which still imports a lot of gas. We can also build positive relationships with the enormous emerging markets of China and India, both of whom want and will need enormous supplies of energy for many decades.
I would like to be able to offer partners the alternative option of buying Canadian energy so that they are less reliant on, say, Iranian or Russian energy.
Canada can also maybe eventually help the two billion people in the world currently without energy access.
CEC: What benefits could Canadians gain by becoming an energy superpower?
DD: The first and primary responsibility of our federal government is to look after Canada. At the end of the day, the goal is to improve Canada’s welfare and enhance its sovereignty.
More carbon energy development helps Canada. We have massive debt, an investment crisis and productivity problems that we’ve been talking about forever. Economic and job growth are weak.
Solving these will require profitable and productive industries. We don’t have so many economic strengths in this country that we can voluntarily ignore or constrain one of our biggest industries.
The economic benefits pay for things that make you stronger as a country.
They make you more resilient on the social welfare front and make increasing defence expenditures, which we sorely need, more affordable. It allows us to manage the debt that we’re running up, and supports deals for Canada’s Indigenous peoples.
CEC: Are there specific projects that you advocate for to make Canada an energy superpower?
DD: Canada’s energy needs egress, and getting it out to places other than the United States. That means more transport and port facilities to Canada’s coasts.
We also need domestic energy transport networks. People don’t know this, but a big chunk of Ontario’s oil supply runs through Michigan, posing a latent security risk to Ontario’s energy security.
We need to change the perception that pipelines are evil. There’s a spiderweb of them across the globe, and more are being built.
Building pipelines here, with Canadian technology and know-how, builds our competitiveness and enhances our sovereignty.
Economic growth enhances sovereignty and provides the resources to do other things. We should applaud and encourage it, and the carbon energy sector can lead the way.

Oil tanker traffic surges but spills stay at zero after Trans Mountain Expansion
From the Canadian Energy Centre
Bigger project maintains decades-long marine safety record
The Trans Mountain system continues its decades-long record of zero marine spills, even as oil tanker traffic has surged more than 800 per cent since the pipeline’s expansion in May 2024.
The number of tankers calling at Trans Mountain’s Westridge Marine Terminal in the Port of Vancouver in one month now rivals the number that used to go through in one year.
A global trend toward safer tanker operations
Trans Mountain’s safe operations are part of a worldwide trend. Global oil tanker traffic is up, yet spills are down, according to the International Tanker Owners Pollution Federation, a London, UK-based nonprofit that provides data and response support.
Transport Canada reports a 95 per cent drop in ship-source oil spills and spill volumes since the 1970s, driven by stronger ship design, improved response and better regulations.
“Tankers are now designed much more safely. They are double-hulled and compartmentalized to mitigate spills,” said Mike Lowry, spokesperson for the Western Canada Marine Response Corporation (WCMRC).

From eight marine bases including Vancouver and Prince Rupert, WCMRC stands at the ready to protect all 27,000 kilometres of Canada’s western coastline.
Lowry sees the corporation as similar to firefighters — training to respond to an event they hope they never have to see.
In September, it conducted a large-scale training exercise for a worst-case spill scenario. This included the KJ Gardner — Canada’s largest spill response vessel and a part of WCMRC’s fleet since 2024.
“It’s part of the work we do to make sure everybody is trained and prepared to use our assets just in case,” Lowry said.

WCMRC’s fleet and capabilities were doubled with a $170-million expansion to support the Trans Mountain project.
Between 2012 and 2024, the company grew from 13 people and $12 million in assets to more than 200 people and $213 million in assets.
“About 80 per cent of our employees are mariners who work as deckhands, captains and marine engineers on our vessels,” Lowry said.
“Most of the incidents we respond to are small marine diesel spills — the last one was a fuel leak from a forest logging vessel near Nanaimo — so we have deployed our fleet in other ways.”
Tanker safety starts with strong rules and local expertise

Speaking on the ARC Energy Ideas podcast, Trans Mountain CEO Mark Maki said tanker safety starts with strong regulations, including the use of local pilots to guide vessels into the harbour.
“On the Mississippi River, you have Mississippi River pilots because they know how the river behaves. Same thing would apply here in Vancouver Harbour. Tides are strong, so people who are familiar with the harbor and have years and decades of experience are making sure the ships go in and out safely,” Maki said.
“A high standard is applied to any ship that calls, and our facility has to meet very strict requirements. And we have rejected ships, just said, ‘Nope, that one doesn’t fit the bill.’ A ship calling on our facilities is very, very carefully looked at.”
Working with communities to protect sensitive areas
Beyond escorting ships and preparing for spills, WCMRC partners with coastal communities to map sensitive areas that need rapid protection including salmon streams, clam beds and culturally important sites like burial grounds.
“We want to empower communities and nations to be more prepared and involved,” Lowry said.
“They can help us identify and protect the areas that they value or view as sensitive by working with our mapping people to identify those areas in advance. If we know where those are ahead of time, we can develop a protection strategy for them.”
