Introducing New Technologies

Impact Carbon supports locally appropriate and commercially viable technologies to ensure maximum uptake and scale. We continually assess new and innovative technologies in order to best address the needs of our customers.

Improved Cookstoves

By supporting projects to distribute a variety of high performing fuel-efficient cookstoves, Impact Carbon reduces the consumption of biomass fuels, limits exposure to deadly indoor air pollution (IAP) and saves families time spent collecting wood and/or money spent purchasing fuel.

Household Charcoal Stoves

Household charcoal stoves reduce 36% of fuel consumption. 100% of customers report fewer indicators of  exposure to indoor air pollution after adopting charcoal stoves. Families using these stoves save more than $110 in fuel costs each year and each stove reduces the equivalent of 2.81 tons of carbon dioxide equivalent annually. 

Household Wood Stoves

Household wood stoves reduce fuel consumption by 32% - 65%. These stoves reduce between 38% - 51.2% of particulate matter emissions. Each stove reduces the Impact Carbonequivalent of between 1-5 tons of carbon dioxide emissions annually.

Institutional Wood Stoves

Stoves installed in schools, hospitals, and businesses reduce fuel consumption by about 45%. All cooks report fewer indicators of exposure to indoor air pollution. Institutions save approximately 56 tons of fuel each year, and each stove reduces the equivalent of 86.41 tons of carbon dioxide annually. 

Biomass Semi-Gasifier Household Stoves

Impact Carbon is disseminating fuel-switching semi-gasifier stoves in China to help customers transition from coal to 100% renewable biomass. The stoves have an average efficiency ranging from 40% - 89% and reduce 100% of coal use, equaling up to 2.18 tons per year among families previously using coal.  Families adopting biomass gasifier stoves save up to $445 per year, approximately 18% of annual household income in China. The stoves also reduce the equivalent of 4.5 - 5.7 tons of carbon dioxide annually.

Ethanol Household Stoves

Fuel-switching ethanol household stoves enable customers in Mozambique to transition from charcoal to 100% renewable ethanol. The stoves reduce 100% of charcoal use, equaling up to 0.73 tons of charcoal per year among families previously using charcoal.  The stoves reduce the equivalent of 7.49 tons of carbon dioxide annually.

Water Treatment Technologies

Impact Carbon supports the distribution and installation of water purification devices and systems that allow families to access clean water, thereby reducing exposure to dangerous waterborne pathogens. We support a variety of cutting edge communal and household level water treatment technologies.

Ultra Filtration Systems

Ultra Filtration Systems remove all bacteria, viruses, cysts, parasites, fungi and all other microbiological waterborne pathogens.

Ceramic Chujio Filter in Uganda

Ceramic Water Filters

High quality ceramic filters block the passage of any particles larger than the pore size including bacteria, protozoa, and microbial cysts, removing 99.9% of all microorganisms. The water is additionally treated by a silver element included within the filter to further remove or destroy bacteria and viruses present in the water and reduce the recontamination risk of stored filtered water.

UV Water Treatment in Ugandan School

Solar Ultraviolet (UV) Treatment

These technologies are effective through the inactivation of pathogens through heat and UV disinfection, using ultraviolet (UV) light at sufficiently short wavelength to inactivate microorganisms.

Chlorine Dispenser Systems

Chlorine dispensers are installed next to communal water sources to allow for point-of-use treatment. The chlorine supply is regularly replenished. 

Maomo Water Vendor Uganda

Chlorine Kiosks

Safe water vendors sell chemically treated water to communities. 


Boreholes are installed in communities to provide access to safer ground water. Each borehole serves approximately two to four hundred households, depending on the region.
