How community and social impact projects can reduce CO₂

Many everyday solutions — from clean cookstoves to improved energy access — support people while reducing emissions. The measured savings are documented and issued as CO₂ certificates.

How CO₂ reductions are generated

In community and social impact projects, CO₂ reductions result from practical improvements in daily life: less fuel use, cleaner technologies or more efficient basic services.

All of these measures prevent emissions that would otherwise have occurred.

In many regions, households cook over open fires, rely on kerosene-based lighting or boil water to make it safe to drink. These activities require large amounts of wood, charcoal or fossil fuels — and release significant CO₂ and other pollutants.

When projects introduce clean cookstoves, provide access to safe drinking water or offer energy-efficient household solutions, fuel consumption decreases noticeably. Every unit of fuel that is not burned results in measurable CO₂ reductions.

For each project, the expected consumption without the intervention (baseline) is compared with actual consumption after the new solution is in use. This calculation is based on defined emission factors as well as local fuel-use studies and monitoring data.

The difference shows how many emissions have genuinely been avoided. These values are measured, verified and regularly updated — and form the basis for issuing CO₂ certificates.

  • In many rural regions, households use kerosene lamps for lighting in the evening. A typical lamp burns around 80 litres of kerosene per year.

    Through the project, households receive solar-powered lamps or small solar home systems. As a result, kerosene consumption is eliminated entirely.

    For the calculation, a defined emission factor is used to indicate how much CO₂ is produced when kerosene is burned:

    1 litre of kerosene = 2.4 kg CO₂

    The CO₂ reduction is calculated as follows:

    80 litres of kerosene that are no longer burned
    ×
    2.4 kg CO₂ per litre
    =
    192 kg CO₂ reductions per household per year
    =
    0.192 t CO₂ per year

    This amount is monitored, verified and issued as 0.192 CO₂ certificates – always one certificate per tonne of avoided CO₂.

     

    Note: This example illustrates the basic principle of emission reductions in community and social impact projects. Whether a project is eligible to generate certificates depends on strict requirements: recognised standards (e.g., Gold Standard or Verra/VCS), defined fuel-use studies, independent verification and ongoing monitoring. Not every social intervention automatically qualifies for certification.
  • For emission reductions from community and social impact projects to be issued as CO₂ certificates, they must meet strict requirements. The reductions must be additional — meaning that without the project, the fuel consumption, energy use or emission-intensive practices would have remained unchanged.

    The impact must also be measurable, traceable and verifiable. International standards such as Gold Standard or Verra (VCS) define exactly how baselines are calculated, how fuel use and behavioural data must be monitored, and which evidence a project has to provide.

    Independent auditors regularly verify on site whether the technologies are being used correctly, whether the reported savings are plausible and whether the calculations comply with the required methodologies.

    Only when all data are complete and coherent can a CO₂ certificate be issued — always representing one tonne of avoided CO₂.

    This creates a transparent process that ensures every certificate reflects a real and verified climate impact.

  • Not every social project can automatically generate CO₂ certificates. Many initiatives create important community benefits, but they do not produce measurable emission reductions that meet the requirements of international standards.

    Projects are not eligible for certification if they:

    • do not reduce fuel or energy consumption, such as purely educational, health or income-support programmes.

    • do not allow a clear baseline, meaning it is impossible to determine previous fuel use or emissions.

    • cannot be measured or verified, for example when reliable usage or impact data are missing.

    • provide social support only, such as school materials, trainings, community development or microfinance, without avoiding emissions.

    • aim solely at behavioural change without a technological component, since this cannot be quantified or guaranteed over time.

    Only initiatives that deliver technically measurable and verifiable emission reductions, supported by regular monitoring, can generate CO₂ certificates.

Which project types are included?

Community & Social Impact projects come in different forms. These are the eight most relevant categories:

  • Improved access to clean energy

    Community energy solutions such as small solar or hybrid systems for schools, health centers or village hubs replace diesel generators or kerosene lamps. This leads to direct and measurable emission reductions.

  • Community water and sanitation systems

    Centralized water treatment or distribution facilities – such as borehole pumps or solar-powered water stations – reduce fuel consumption because less water must be boiled or transported over long distances.

  • Community cooking systems

    Efficient large-scale kitchens for schools, clinics or camps save substantial amounts of firewood by using optimized, high-capacity cooking technologies. These systems operate differently from individual household stoves and follow dedicated methodological requirements.

  • Waste reduction and community-based recycling

    Organized collection points, local sorting facilities or initiatives to reduce plastic and biomass waste lower emissions by preventing open burning or the formation of landfill gases.

  • Clean mobility for communities

    Shared transport solutions such as bicycle schemes or solar-powered vehicles for medical services replace fossil-fuel trips. A verifiable comparison to previous diesel or gasoline use is required.

  • Community biogas systems

    Biogas facilities for villages, schools or public institutions replace firewood, charcoal or kerosene. The resulting emission savings can be clearly measured and verified.

  • Open-burning prevention projects

    Community-based measures that prevent the open burning of household waste or agricultural residues avoid significant CO₂ and black carbon emissions and can therefore be certified.

  • Community energy or heat hubs

    Local energy centers that provide solar power, charging stations or efficient devices for shared use reduce the need for individual diesel generators or fossil-based heating systems.

  • To ensure that the CO₂ reductions of a community project are reliable, they are monitored regularly. Project operators collect data on usage, fuel savings or the actual avoidance of fossil energy—depending on the project type. Each technology follows clearly defined requirements and standardized methodologies.

    Independent auditors review this data on-site and compare it with the rules of recognized standards such as Verra or Gold Standard. They assess whether the systems are being used as intended, whether the documented savings are plausible, and whether the project genuinely benefits the community.

    Only when all evidence is complete and consistent is the verified CO₂ reduction documented and approved for the issuance of certificates.

    This creates a transparent process that ensures every certificate reflects a real, verified and socially grounded climate impact.

What additional benefits do these projects provide?

Greater everyday safety through fewer open fires, fewer hazardous trips to collect water or fuel, and reduced accident risks…

  1. 1

    Stronger community structures

    Projects are used collectively — strengthening cooperation, participation and local organization.

  2. 2

    More time for education, work and daily life

    Less firewood gathering, fewer long trips, less improvisation: many families gain significant time.

  3. 3

    Improved health

    Less smoke, fewer pollutants, fewer open fires: exposure to soot and harmful emissions decreases noticeably.

  4. 4

    Local economic opportunities

    Construction, operation and maintenance create jobs and support small businesses and craft-based activities.

  5. 5

    Better access to energy and essential services

    Community solutions provide electricity, heat, water or mobility — often for the first time in a reliable and affordable way.

  6. 6

    Protection of natural resources

    Lower firewood consumption eases pressure on forests, reduces deforestation and limits strain on local biomass supplies.

  7. 7

    Less waste and a cleaner environment

    Recycling structures and the prevention of open burning improve air quality and the cleanliness of community spaces.
