Increasing access to clean cooking stoves and fuels reduces greenhouse gas emissions while creating positive health and wellbeing outcomes for beneficiaries.

Why is it important?

Cookstoves are a daily necessity for billions of people worldwide. 2.3 billion people depend on open fires or inefficient stoves to cook globally. (1) To address this need, international organisations have distributed over 115 million clean and efficient cookstoves and fuels since 2010, mostly focusing on rural and low-income settings. (2) However, many of these stoves rely on biomass fuels like wood and charcoal, leading to significant environmental and health consequences. The use of these fuels contributes to deforestation, exacerbating climate change. Additionally, the toxic emissions from these stoves cause serious respiratory illnesses, particularly among women, who are often the primary cooks in their households.

Moreover, the burden of fuel collection falls heavily on women and children, who can spend up to 20 hours a week gathering firewood. (3) As firewood becomes scarcer, especially in regions like Africa, these individuals are forced to walk increasingly long distances, sometimes up to a day, to find fuel. This not only exposes them to the risk of abuse in isolated areas but also takes away time they could use for education, work, or other productive activities. (4)

What's the solution?

Increasing access to both efficient stoves and fuels is key to promoting clean cooking. When cooking for large groups in settings such as refugee camps, schools, and hospitals, prioritising institutional stoves can lead to greater savings in money, fuel, and time compared to household stoves. Incorporating heat retention systems, made from materials like hay or cloth, can also improve cooking efficiency by preventing heat loss. When selecting stoves, choose the least impactful option based on the context. However, consider the availability and cultural acceptability of fuel, ensuring infrastructure is in place for easy refills. Additionally, improving ventilation is crucial, as even low-emission stoves can be harmful in poorly ventilated spaces. Finally, training users on proper stove use and maintenance is essential to maximise the environmental and health benefits of clean cooking technologies.

Implementing clean cooking practices and technology can help mitigate the environmental and health problems attributed to inefficient stoves and biomass fuels.

  • Point of attention

    To achieve WHO guidelines for indoor air quality users must use clean stoves and fuels almost exclusively, (5) but there is often incorrect, inconsistent, and non-exclusive use. (6)

Key figures

2%

of global CO2 emissions is attributed to the burning of wood fuels. (7)

4 million

people die every year from illnesses associated with cooking smoke. (8)

34%

As much as 34% of harvested wood fuel is sourced unsustainably, leading to forest degradation and exacerbating climate change. (9)

20 hours a week

The amount of time women and children spend gathering fuel for cooking in developing countries. (10)

50%

Heat retention cookers save up to 50% of required cooking energy. (11)

30-60%

Efficient stoves can reduce the use of fuel by 30% to 60%, whilst at the same time leading to better health outcomes. (12)

Key actions

  • #1 Prioritise institutional stoves in refugee camps, schools, and hospitals

    Choose institutional stoves when cooking for a large group because they can have larger monetary, fuel, and time saving relative to household stove changes. (13)

  • #2 Use heat retention systems

    Selecting stoves with heat retention systems are traditional and efficient ways to cook items. Often made of hay, cloth, or another material it makes it easier to cook after setting the right temperature because the insulation prevents the heat from dissipating. (14)

  • #3 Choose the least impactful stove depending on the setting

    Prioritise electric stoves that use energy from decarbonised sources, however, the context and accessibility of electricity and the price of electric stoves should be considered. Solar cookers do not produce emissions when used, but are only adapted for certain climates because they must be in the sun during midday. LPG and ethanol (from renewable sources) stoves are less emissive than biomass or coal, but LPG remains a fossil source. Fuel for biomass stoves is often collected unsustainably and most improved cookstoves do not comply with clean cooking standards. Use efficient cookstoves. Refer to the MECS/WFP report for an overview of options.

  • #4 Consider the accessibility and acceptability of fuel

    Make alternative fuels more accessible to be competitive. This will involve establishing an infrastructure for refills to ensure that the fuel is adopted. Stoves are usually designed for a specific fuel so making sure the fuel is available will help ensure the use of the stoves. (15) The cultural context and the cost of fuel are additional factors that need to be considered.

  • #5 Increase ventilation

    Increase ventilation as a low-emission stove in a room with poor ventilation can be more harmful to human health than a high-emission stove used outside with good ventilation. Location and design should be considered in clean cooking systems. (16)

  • #6 Increase training for proper stoves use

    Train users on the proper use and maintenance of provided stoves. As relevant, address barriers to uptake.  In order to achieve positive environmental and respiratory health impacts from the use of clean stoves and fuels users must use them exclusively and correctly. (17)

To consider

  • Potential co-benefits

    • Health improvements: Reduced health risks for households and communities.
    • Environmental benefits: Cleaner and healthier community environment.
    • Cleaner and healthier community environment.
    • Resource conservation: Reduced need for raw materials such as firewood.
  • Success conditions

    • Community engagement: Widespread adoption by households and community leaders.
    • Financial accessibility: Access to financial resources for purchase and maintenance.
    • Cross-sector collaboration: Collaboration between government, NGOs, and local communities.
  • Prerequisites & specificities

    • Regulatory compliance: Adherence to local and national safety and emissions regulations.
  • Potential risks

    • Infrastructure challenges: Inadequate infrastructure for clean fuel supply.
    • User education: Improper use or lack of maintenance of the stoves.
    • Economic barriers: High costs preventing adoption in low-income communities.

Success stories

UNFCC Efficient Cooking Program (ECP) in Ecuador

The ECP is replacing liquefied petroleum gas-based cooktops and water heaters with electric systems. It is estimated to save 2.8 million tonnes of CO2e per year and is aiming to reach 3 million families, which is 83% of the population.

Impact Carbon: Increased acquisition of stoves in Uganda

In villages around Mbarara, Uganda acquisition of sustainable stoves increased from 4.6% to 57% through Impact carbons use of novel sales like free trials, return options, and time payments.
