Gas Flaring and Venting Summary

Core Content

Gas flaring and venting refer to the practice of burning or releasing associated gas (a byproduct of oil production) into the atmosphere. This occurs primarily in developing countries, where the volume of flaring and venting is disproportionately high, despite its negative environmental and economic impacts.

Main Points

Environmental and Economic Impact

• Gas flaring and venting contribute significantly to greenhouse gas emissions.
• In Africa, flaring and venting account for half of the continent’s power consumption.
• The World Bank estimates that 110 billion cubic meters (bcm) of natural gas is flared and vented globally each year, enough to meet the annual consumption of Central and South America or Germany and Italy.
• The gas flared in Africa (37 bcm) could generate 200 terawatt-hours (TWh) of electricity, more than twice the power consumption of Sub-Saharan Africa (excluding South Africa).

Global Gas Flaring by Country

• Developing countries account for over 85% of global gas flaring and venting.
• Major flaring countries include Nigeria, Iraq, Iran, and the Russian Federation.
• Countries like Cameroon, Equatorial Guinea, and Iraq flare or vent 31–61 cubic meters of gas per barrel of oil, indicating low utilization rates.

Regulatory and Market Barriers

• Most developing countries lack efficient regulatory frameworks and transparent legal procedures for managing gas flaring.
• Preemptive rights in production contracts often prevent operators from selling associated gas to third parties, limiting market access.
• Distorted energy prices, monopolistic state-owned utilities, and lack of infrastructure hinder the development of domestic or international gas markets.

Fiscal Incentives and Financial Constraints

• Fiscal policies such as taxes, royalties, and production sharing contracts can influence gas utilization.
• However, these incentives must be sufficiently attractive compared to oil production to be effective.
• Many developing countries face financing constraints, as commercial financiers are reluctant to invest in projects with high risk.
• Projects that reduce gas flaring may qualify for concessional financing or carbon credits under the Kyoto Protocol's Clean Development Mechanism.

Voluntary Standards and Collaboration

• The Global Gas Flaring Reduction (GGFR) Public-Private Partnership has endorsed a voluntary standard to reduce gas flaring and venting.
• The standard promotes collaboration among stakeholders, including governments, operators, and NGOs, to address barriers to gas utilization.
• It encourages an integrated approach, combining market development, infrastructure investment, regulatory reform, and carbon credit trading.

Lessons from Successful Countries

• Countries like Canada, Norway, the UK, and the US have reduced gas flaring by:
  • Establishing efficient legal and regulatory frameworks.
  • Reforming natural gas markets.
  • Allowing private participation in gas infrastructure.
  • Creating financial incentives for gas utilization.
• Close collaboration between governments, regulators, and operators is essential for success.
• No single solution works universally; each country must tailor its approach based on legal, political, and institutional context.

Key Information

• Annual gas flaring: ~110 billion cubic meters (bcm).
• Major flaring countries: Nigeria (10–20 bcm), Iraq (10–20 bcm), Iran (10–20 bcm), Russia (16 bcm).
• Gas utilization per barrel of oil:
  • Developing countries: 31–61 cubic meters.
  • High utilization countries: <2 cubic meters (e.g., Norway, US, UK).
• Value of flared gas: ~$20 billion annually if exported to US or European markets.
• GGFR Partnership: Includes over 70% of global flaring and venting, with members such as the World Bank, OPEC, and major oil companies.

Conclusion

Gas flaring and venting are major environmental and economic challenges, especially in developing countries. Addressing these issues requires a multifaceted approach that includes regulatory reform, market access, fiscal incentives, and collaboration between stakeholders. The GGFR Partnership provides a model for global cooperation in this effort, emphasizing the need for voluntary standards and integrated solutions. Ultimately, reducing gas flaring and venting is essential for sustainable development and climate change mitigation.
