In this article, we discussed flaring reduction, the impact, Strategies and technologies to achieve flaring reduction, flaring reduction goals and challenges to achieving flaring reduction goals.
Definition
Flaring reduction is the practice of minimizing or eliminating the routine burning of natural gas that is released during oil extraction, which is a significant source of greenhouse gas emissions, wasted energy, and air pollution. Strategies for flaring reduction include repurposing the gas for power generation or other industrial uses, developing infrastructure to transport and market the gas, overcoming technical and regulatory barriers, and implementing innovative business models, all supported by global initiatives like the World Bank’s Global Flaring and Methane Reduction Partnership (GFMR) to achieve zero routine flaring by 2030.
The Impacts of Gas Flaring
The practice of gas flaring has severe and multi-faceted consequences:
Environmental Degradation and Climate Change: Flaring releases greenhouse gases, including carbon dioxide (CO 2 ) and methane (CH4 ), contributing to climate change. Methane, in particular, is a potent greenhouse gas with a much higher warming potential than CO2 in the short term. The flares also emit toxic pollutants like sulfur dioxide (SO2 ), nitrogen oxides (NOx ), and volatile organic compounds (VOCs) that can lead to acid rain and air pollution, damaging local ecosystems, agricultural productivity, and human health. The release of black carbon (soot) from incomplete combustion also contributes to climate change and can have localized effects like the melting of Arctic ice.
Economic Waste: Flaring represents a colossal waste of a valuable natural resource. The World Bank estimates that the volume of gas flared annually could be enough to power the entire African continent or meet a significant portion of the energy needs of major economies. This wasted gas has a market value in the tens of billions of dollars, representing lost revenue for both companies and host governments.
Public Health and Social Issues: Communities living near flare sites are disproportionately affected. Exposure to the toxic pollutants released by flares is linked to a range of health problems, including respiratory illnesses, skin conditions, and cardiovascular issues. The noise and constant light from flares also cause social disruption and are a visible symbol of environmental injustice.
Strategies and Technologies to Achieve Flaring Reduction:
Achieving flaring reduction goals requires a multi-pronged approach involving technological solutions, policy changes, and commercial innovation. Key strategies include:
Flare Gas Recovery Systems (FGRS): These systems are one of the most effective ways to reduce flaring. An FGRS captures the waste gas that would normally be flared, processes it, and then redirects it for productive use, such as generating power for the facility, or for sale. This not only reduces emissions but also creates an economic return on a previously wasted resource.
Improving Combustion Efficiency: For flaring that cannot be eliminated, such as for safety reasons, optimizing the flare’s combustion efficiency is critical. Technologies like enclosed ground flares and multi-point ground flares ensure more complete combustion, significantly reducing the emission of unburned hydrocarbons, including methane and black carbon.
Gas Utilization and Monetization: The most sustainable solution is to find productive uses for the associated gas. This can involve:
Power Generation: Using the gas to fuel turbines to generate electricity for the oil field itself, or for local communities.
Re-injection: Pumping the gas back into the reservoir to enhance oil recovery or for long-term storage.
Gas-to-Liquids (GTL) and Compressed Natural Gas (CNG): Converting the gas into transportable liquids or compressed forms to be sold in local or regional markets.
Liquefied Natural Gas (LNG): For larger volumes of gas, building small-scale LNG facilities can be a viable option for a wider market.
Flaring Reduction Goals: Global and Corporate Commitments
World Bank Zero Routine Flaring by 2030 Initiative
Endorsed by over 90 governments, oil companies, and development institutions
Goal: eliminate routine flaring by 2030 — defined as flaring during normal oil production in the absence of facilities to use the gas
United Nations Climate Targets (NDCs & Net Zero)
Many countries include flaring reduction as part of their Nationally Determined Contributions (NDCs) under the Paris Agreement
Global Methane Pledge
Launched at COP26, over 150 countries have agreed to reduce methane emissions by 30% by 2030, which includes curbing flaring and venting in oil and gas operations
Oil & Gas Company Commitments
Many major producers have set specific flaring goals:
ExxonMobil: Reduce flaring intensity by 60% by 2030
Shell: Zero routine flaring by 2025 (for operated assets)
Chevron: Targeting 3% or lower flaring intensity by 2028
Saudi Aramco: Already operates one of the lowest flaring intensities globally (less than 1%), aiming for continuous improvement
Equinor: Targets near-zero flaring and methane emissions by 2030.
Challenges and the Path Forward
Despite the progress, significant challenges remain. The economic viability of flaring reduction projects can be highly sensitive to natural gas prices and the availability of infrastructure. In remote locations or fields with small, scattered gas volumes, it can be difficult to justify the investment in gas-gathering and processing infrastructure.
To accelerate progress, it is essential to:
Foster Collaboration: Encourage cooperation between different stakeholders, including governments, international oil companies, and local communities, to develop integrated solutions.
Increase Transparency: Improve the monitoring and reporting of flaring and venting volumes, using tools like satellite data, to ensure accountability and track progress.
Reform Regulations: Implement effective regulatory frameworks and fiscal policies that create a clear and consistent incentive for investment in flaring reduction.
The Business Case for Reducing Flaring
Beyond ESG and climate pressures, flaring reduction increasingly makes strong business sense:
Regulatory compliance: Avoid penalties and reputational damage
Investor confidence: ESG investors demand flaring and methane transparency
Revenue generation: Captured gas can be monetized
Operational safety: Reducing flaring can minimize hazards in high-pressure systems
License to operate: Reducing community and environmental impacts secures social acceptance.
Conclusion
Flaring reduction is more than a climate imperative — it’s an opportunity to align environmental responsibility with operational efficiency and economic value. With clear goals, the right incentives, and continued innovation, the oil and gas industry can dramatically curb flaring, reduce emissions, and contribute meaningfully to a lower-carbon future.
