Green Heat is an enterprise installing and marketing biogas digesters that convert decaying organic material from latrines and agricultural waste into biogas fuel for cooking and heating. By using biogas digesters, urban and rural households, schools, prisons, hospitals and tourist lodges in Uganda reduce their dependence on firewood and charcoal, improve their waste management systems, and help reduce deforestation and greenhouse gas emission rates related to methane release.

The enterprise won a SEED Low Carbon Award in 2014, which were supported by the International Climate Initiative (ICI) of the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB).
