The following video shows how Toyola stoves in Ghana have been able to market a product that saves consumers money by using lower levels of charcoal. This also has a clear positive impact on the environment, by reducing the number of trees that have to be cut and also generates health benefits, since the more efficient stoves also create less smoke.

However the cost of the stoves can be too high for local consumers. This provides an opportunity for carbon-offer schemes:

Carbon offset projects around the world enable you to immediately meet your carbon reduction target and finance the development of crucial renewable energy and resource conservation activities. Many projects also deliver benefits to communities and biodiversity, providing a positive association for your brand.

Such schemes make the stoves more affordable and enable polluters in richer countries to meet their carbon emission targets.
