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.
Sources: World Bank (undated) and EIA (2023)
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.

For second year in a row, Alberta oil and gas companies spend more than required on cleanup
From the Canadian Energy Center
By Grady Semmens$923 million spent cleaning up inactive wells, sites and pipelines in 2023
As a business owner, Ryan Smith values few things more than predictability when it comes to the oil and gas market and the demand for his company’s services.
That’s why knowing that next year in Alberta, the regulator requires at least $750 million worth of work cleaning up inactive oil and gas wells and other legacy energy infrastructure is tremendously helpful for the CEO of Calgary-based 360 Engineering & Environmental Consulting.
“Having a minimum spend in place for the province makes the market more predictable and consistent, which in turn helps our clients and our business plan for the future, which is a good thing,” says Smith, whose company has completed more than 5,000 site closure activities in Canada and internationally since 2015.
“Site closure has really emerged as a growth market over the last decade, especially in Western Canada where the regulatory systems for oil and gas are more advanced than anywhere else we are exposed to. It is an integral part of the energy lifecycle, and if it is done well it adds a lot of value to the industry.”
The Alberta Energy Regulator (AER) introduced an industry-wide minimum “closure” spending requirement in 2022, part of Alberta’s Inventory Reduction Program to accelerate the remediation of inactive oil and gas wells, facilities and pipelines across the province.
The mandatory quota determines the minimum level of work a company must conduct primarily to decommission and reclaim a proportion of its inactive inventory.
Inactive wells are defined as those that have not been used for six months or a year, depending on what they are being used for. When a company decides that they will not reactivate an inactive well they decommission it through a process called abandonment.
A well is considered successfully abandoned after it is cleaned, plugged with cement, cut to a minimum of one meter below the surface and covered with a vented cap. After abandonment comes remediation and reclamation, where the land around the well is returned to the equivalent of its original state.
The first two years under the new rules saw Alberta’s energy industry significantly exceed the minimum closure requirements.
In 2022, companies spent more than $696 million, about 65 per cent more than the initial threshold of $422 million. The AER increased the minimum spend to $700 million in 2023, which producers surpassed by 22 per cent with total expenditures of $923 million.
The 2024 minimum remains at $700 million, while in July the regulator announced that the minimum spend for 2025 was raised to $750 million.
This closure work does not include remediation of oil sands mining sites, which is handled under the Mine Financial Security Program, nor does it include the closure of orphan wells (wells without a legal owner) managed by the industry-funded Orphan Well Association.
Gurpreet Lail, CEO of Enserva, an industry association representing energy service companies, suppliers and manufacturers, says there was an initial rush of closure work when the quotas were first put in place, but activity has since become more even as companies develop long-term closure plans.
“A lot of the low-lying fruit has been taken care of, so now companies are working on more complex closure files that take more time and more money,” Lail says.
Facility owners say that Alberta’s rules provide direction for planning closure and remediation work, which in the past may have been put on hold due to the ups and downs of the oil and gas market.
“When commodity prices are up, everyone is focused on drilling more wells and when prices are down, budgets are strained for doing work that doesn’t bring in revenue. Having a minimum spend makes sure closure work happens every year and ensures there is longer-term progress,” says Deborah Borthwick, asset retirement coordinator for Birchcliff Energy, an oil and natural gas producer focused in Alberta.
Over the last few years, Birchcliff has budgeted more than $3 million for annual facility closure work, far above its required minimum spend.
The company completed 11 well abandonments and decommissioned 23 facilities and pipelines in 2022, according to its latest environmental, social and governance report.
Borthwick says having the closure quota for 2025 already set has allowed it to plan ahead and line up the necessary service companies well in advance for next year’s remediation work.

Heavy-duty truckers welcome new ānatural gas highwayā in Alberta

New compressed natural gas fueling stations in Grande Prairie and Calgary join new stop in Edmonton
Heavy-duty truckers hauling everything from restaurant supplies to specialized oilfield services along one of Western Canada’s busiest corridors now have more access to a fuel that can help reduce emissions and save costs.
Two new fuelling stations serving compressed natural gas (CNG) rather than diesel in Grande Prairie and Calgary, along with a stop that opened in Edmonton last year, create the first phase of what proponents call a “natural gas highway”.
“Compressed natural gas is viable, it’s competitive and it’s good for the environment,” said Murray Mullen, chair of Mullen Group, which operates more than 4,300 trucks and thousands of pieces of equipment supporting Western Canada’s energy industry.
Right now, the company is running 19 CNG units and plans to deploy another 15 as they become available.
“They’re running the highways right now and they’re performing exceptionally well,” Mullen said on Oct. 22 during the ribbon-cutting ceremony opening the new station on the northern edge of Calgary along Highway 2.
“Our people love them, our customers love them and I think it’s going to be the way for the future to be honest,” he said.

According to Natural Resources Canada, natural gas burns more cleanly than gasoline or diesel fuel, producing fewer toxic pollutants and greenhouse gas emissions that contribute to climate change.
The two new CNG stops are part of a $70 million partnership announced last year between major Canadian natural gas producer Tourmaline and California-based Clean Energy Fuels.
Their deal would see up to 20 new CNG stations built in Western Canada over the next five years, daily filling up to 3,000 natural gas-fueled trucks.
One of North America’s biggest trucking suppliers to businesses including McDonald’s, Pizza Hut, Subway and Popeye’s says the new stations will help as it expands its fleet of CNG-powered vehicles across Canada.
Amy Senter, global vice-president of sustainability with Illinois-based Martin Brower, said in a statement that using more CNG is critical to the company achieving its emissions reduction targets.
For Tourmaline, delivering CNG to heavy-duty truckers builds on its multi-year program to displace diesel in its operations, primarily by switching drilling equipment to run on natural gas.
Between 2018 and 2022, the company displaced the equivalent of 36 Olympic-sized swimming pools worth of diesel that didn’t get used, or the equivalent emissions of about 58,000 passenger vehicles.

Tourmaline CEO Mike Rose noted that the trucking sector switching fuel from diesel to natural gas is gaining momentum, notably in Asia.
A “small but growing” share of China’s trucking fleet moving to natural gas helped drive an 11 percent reduction in overall diesel consumption this June compared to the previous year, according to the latest data from the U.S. Energy Information Administration.
“China’s talking about 30 percent of the trucks sold going forward are to be CNG trucks, and it’s all about reducing emissions,” Rose said.
“It’s one global atmosphere. We’re going to reduce them here; they’re going to reduce them there and everybody’s a net winner.”
Switching from diesel to CNG is “extremely cost competitive” for trucking fleets, said Clean Energy CEO Andrew Littlefair.
“It will really move the big rigs that we need in Western Canada for the long distance and heavy loads,” he said.
Tourmaline and Clean Energy aim to have seven CNG fuelling stations operating by the end of 2025. Construction is set to begin in Kamloops, B.C., followed by Fort McMurray and Fort St. John.
“You’ll have that Western Canadian corridor, and then we’ll grow it from there,” Littlefair said.
