Gas flaring, the burning of natural gas associated with oil extraction, has persisted since the beginning of oil production, some 160 years ago. It takes place due to a range of issues, from market and economic constraints, to a lack of appropriate regulation and political will, and results in substantial carbon dioxide, methane and black carbon (soot) emissions. Eliminating this practice from oil production is the very least oil and gas operators can do to limit their direct emissions and will help countries achieve their Paris Agreement goals, advancing their path to decarbonization and renewable energy sources. Indeed, if all flaring was eliminated, it would reduce CO2 equivalent emissions by 400 million tons each year.

For many years the World Bank’s Global Gas Flaring Reduction Partnership (GGFR) has ranked the top gas flaring countries in the world by volumes flared and by volumes flared per barrel of oil produced (flaring intensity). However, we have not looked at gas flaring from the oil importer or consumer perspective. With climate action a central focus of many governments and a growing global commitment to “build back better” in the wake of the COVID-19 pandemic and crisis, this is an opportune moment to bring oil-importing countries into the global discussion about ending routine gas flaring.

Gas Flaring volumes

The burden of responsibility to reduce flaring should be shared with countries that import oil, particularly when international agreements and national commitments on climate mitigation incentivize countries to reduce emissions throughout the life cycle. Recognizing this, GGFR created a new metric, the Imported Flare Gas (IFG) Index, which communicates how countries that import crude oil are exposed to gas flaring, a critical climate and resource management issue. The IFG Index quantifies the concept that when a country imports crude oil from another country, it is also importing the flaring intensity of the producing country in proportion to the amount of crude oil imported.    

This new consumer-oriented index should help oil-importing countries recognize that as importers they have an influential role in decarbonizing energy systems globally. The IFG Index can also help oil-importing countries identify “flaring hotspots” in their supply chain, where they are most exposed to flaring among the many countries from which they import oil; engage in a dialogue with countries from which they buy oil; assist producing countries in implementing flaring reduction initiatives; and improve the carbon intensity of the oil they consume.

Preliminary results show that among the Annex I countries importing the greatest quantities of crude oil, Spain, France, Italy, the Netherlands, and Germany have a high IFG index because they are major importers of crude oil from countries that have high gas flaring intensities, such as Algeria, Iraq, Libya, Nigeria, and Russia. These importing countries should shoulder some of the responsibility in the gas flaring reduction efforts of their oil-producing partner countries. But many other countries also share the “gas flaring burden”: Switzerland, Greece, Australia, and Austria rank highest in the index of Annex I countries, irrespective of the amount of crude oil imported, as compared to the international average. This means that these countries may import relatively less crude oil, but what they do import is from oil-producing countries with high flaring intensities. Although the European Union accounted for only 0.17 percent of global gas flaring in 2020, its members can leverage their buying power to influence suppliers and producers, catalyzing gas flaring reduction efforts.

This graph presents the Imported Flare Gas Index for all large crude importing countries. The horizontal line represents international average flaring intensity and the vertical line represents a mark of 1 million barrels per day of oil import. Those countries that appear in the top-right quadrant are countries that have a high intensity and high import: they import more than a million barrels of crude oil per day and have a higher than average imported flare intensity.

IFG index

This chart shows preliminary results of this analysis – a ranking of Annex I countries in terms of their imported flare intensity – with Switzerland, Greece, Australia, Austria, and Spain among the highest and Japan, Iceland, Estonia, and Luxembourg among the lowest. Looking at the breakdown of where most of this intensity is imported from, it is clear that countries with the higher IFG Index are importing a lot of crude oil from high flaring countries, such as Algeria, Iraq, Libya, Nigeria, and Russia.

2020 IFG index results


The IFG index is based on a simple approach that incorporates two data sets available – one is the producer’s flaring intensity from GGFR satellite data and the other is crude oil import data from Comtrade. The methodology to calculate the IFG index may be described by the following formula(s):

It has been over five years since the World Bank launched the “Zero Routine Flaring by 2030” initiative, which commits governments and oil companies that endorse the initiative not to routinely flare gas in any new oil field developments and to end routine flaring at their existing oil production sites as soon as possible and no later than 2030. Although global commitments to the initiative now represent almost two-thirds of global gas flaring, and while the World Bank and GGFR have helped governments advance gas flaring reduction programs in several of the highest gas flaring countries, shared responsibility is needed to achieve this goal. While the world transitions to a low-carbon economy, oil and gas will likely remain a significant source of energy for many countries over the next several years. We need producers and consumers to work together if we are to decarbonize the sector. Oil-producing countries should rightfully assume the lion’s share of responsibility for ending routine flaring, but oil-importing countries also have an important part to play.

In the lead-up to the next UN Climate Change Conference (COP26) in Glasgow, governments can encourage oil-producing countries to embed gas flaring reduction in their climate action plans, Nationally Determined Contributions (NDCs), and energy policies and regulations, kickstarting crucial investments in flaring reduction projects. As we race to realize a low-carbon world, let’s work together to get some meaningful climate wins under our belts now.

Countries should be ranked not on absolute flaring number but on flaring intensity. The higher the flaring intensity , the more in-efficiency

December 13, 2021

Flaring intensity is indeed a valuable tool for understanding a country's flaring profile. It allows us to judge oil-producing countries' flare reduction efforts and performance relative to each other normalized by their oil production . In fact, the IFG Index uses flaring intensity as the basis for attributing gas flaring to a countries oil imports. However, looking at absolute flaring volumes is necessary when we look at the issue of gas flaring in a global context. For instance, seven countries (Russia, Iraq, Iran, the United States, Algeria, Venezuela, and Nigeria) account for roughly two-thirds (65%) of global gas flaring and have remained the top seven gas flaring countries for nine years running. If we are to achieve Zero Routine Flaring by 2030, progress will need to be made in all of these countries.

Well said. I am from Nigeria and gas flaring has become a challenge of lack of political Will, greed and corruption. May I add lack of human empathy by the government. So sad

No mention of gas "venting"... any detail available?

December 13, 2021

Venting, when associated gas is released into the atmosphere unburnt, is significantly worse than flaring. The global warming potential of methane is 28 times worse than the same amount of CO2 emissions on a 100-year basis, and over 80 times more powerful on a 20-year basis. This makes the venting of unburnt methane emissions a major threat to progress on climate change mitigation. At present, GGFR uses infrared satellite data (or the heat signature of individual flares) to identify thousands of flaring sites around the world. This data is taken directly from two satellites operated by the U.S. National Oceanic and Atmospheric Administration (NOAA) that scan the globe each day, interpreted with the assistance of The Payne Institute for Public Policy at the Colorado School of Mines, to estimate global flare volumes. However, unburnt methane emissions (venting) cannot be detected in the infrared spectrum, so it's not currently possible to detect global venting volumes with these satellites. GGFR is exploring and analyzing the many emerging technologies that can help detect venting and methane emissions and hope to be able to monitor them in the future, once we have a high degree of confidence in their accuracy.
