Summary of "Clean and Improved Cooking in Sub-Saharan Africa" (November 2014)

Core Content

This report provides a comprehensive landscape analysis of the clean and improved cooking sector in Sub-Saharan Africa (SSA), highlighting the challenges, opportunities, and key factors influencing the adoption of cleaner cooking technologies. It was commissioned by the World Bank's Energy & Extractives Practice (GEEDR) and supported by ESMAP and AFREA, with contributions from a wide range of stakeholders, including industry experts, policy makers, and NGOs.

The report underscores the significant public health and environmental risks associated with traditional solid-fuel cooking, which remains the primary method for over 700 million Africans (82%) and is projected to rise to 850–900 million by the end of the decade. The use of these fuels, particularly in inefficient stoves, leads to high levels of household air pollution (HAP), contributing to nearly 600,000 annual deaths and millions of cases of chronic illness, especially among women and children.

Main Viewpoints

1. Health and Environmental Impacts of Solid-Fuel Cooking

• Solid-fuel cooking is a major contributor to household air pollution (HAP), which is the second-largest health risk factor in SSA.
• HAP is linked to respiratory diseases, including acute lower respiratory infections (ALRI), chronic obstructive pulmonary disease (COPD), and tuberculosis (TB).
• It also contributes to greenhouse gas (GHG) emissions and black carbon, which accelerate climate change by absorbing solar radiation and darkening snow and ice surfaces.

2. Demand for Clean and Improved Cooking Solutions

• There is a growing demand for cleaner and more efficient cooking solutions driven by the increasing pressure on biomass resources and rising fuel prices.
• Consumers are segmented based on income, cooking habits, and access to alternative fuels.
• While there is a willingness to adopt improved cooking solutions, affordability and awareness remain key barriers.

3. Supply of Clean and Improved Cooking Solutions

• The market for clean and improved cookstoves is fragmented, with a variety of technologies and production models.
• The majority of stoves are still produced at the artisanal and semi-industrial levels, with limited industrial-scale production.
• Modern fuel stoves, such as liquefied petroleum gas (LPG) and electric stoves, are less common, with only 5% and 6% of households using them, respectively.

4. Enabling Environment

• The enabling environment for clean cooking is underdeveloped, with limited policy frameworks, weak quality standards, and fragmented supply chains.
• There is a need for stronger stakeholder coordination, improved financing mechanisms, and better information systems to support market growth.

5. Future Outlook

• The next 5–10 years could be a turning point for the clean cooking sector in SSA if supported by political will, technical innovation, and financial investment.
• The report outlines key recommendations for policymakers, including the development of coherent quality standards, support for market development, and integration of clean cooking into broader energy and climate agendas.

Key Information

• Health Impact: Solid-fuel cooking is responsible for nearly 600,000 annual deaths and millions of cases of chronic illness in SSA.
• Environmental Impact: It contributes to 1% of global GHG emissions and 6% of global black carbon emissions.
• Economic Cost: The opportunity cost of solid-fuel cooking is estimated at 3% of regional GDP, including avoidable fuel spending, time lost on firewood collection, and health-related economic burdens.
• Technology Categorization:
  • Improved Cookstoves: Include basic and intermediate models that offer moderate improvements in fuel efficiency and emissions.
  • Clean Cookstoves: Are defined as technologies that reduce particulate matter emissions to low levels, such as advanced biomass gasifier stoves, modern fuels (LPG, electric), and renewable fuels (biogas, ethanol, solar).
• Market Penetration:
  • Only 11% of households use "clean" cookstoves.
  • Intermediate improved cookstoves (ICS) are used by about 3.5% of households.
  • Advanced biomass gasifier stoves and renewable fuel stoves are still in the pilot stage and represent less than 1% and 0.1% of the market, respectively.
• Challenges:
  • Limited affordability and awareness of clean cooking solutions.
  • Fragmented supply chains and weak quality standards.
  • Insufficient funding and support for market development.
  • Inconsistent definitions and data collection across stakeholders.

Recommendations

• Develop and implement coherent quality and performance standards for cookstoves.
• Strengthen financial and technical support for clean cooking solutions.
• Promote innovation in business models, especially for base-of-the-pyramid (BoP) products.
• Enhance consumer awareness and willingness to pay for improved and clean cooking technologies.
• Support the integration of clean cooking into national energy and climate strategies.
• Encourage public-private partnerships and private-sector investment in the sector.

Conclusion

The clean and improved cooking sector in SSA is at a critical juncture. While there is growing interest and some progress, the sector remains underdeveloped and faces significant challenges. The report serves as a foundational document for future sector analysis and investment, highlighting the need for a coordinated, multi-stakeholder approach to drive sustainable change in cooking practices across the region.
