Africa’s first carbon credit futures based on emissions reductions related to the use of efficient cook-stoves have been sold by Kenya’s BURN.

The company sold 10,000 forward contracts at $25 each and 50,000 call options, which can be exercised at the same price during the next seven years, over CYNK, a Nairobi-based platform, the two companies said in a statement on Monday.

The contracts sold by BURN, which has made and sold more than four million efficient cook-stoves in Africa, are based upon the distribution of electric induction cookers to low-income households in Ghana.

The stoves eliminate or reduce the use of firewood or charcoal for cooking, resulting in less deforestation and emissions of greenhouse gases and health-damaging soot. The company mainly makes clean-burning wood and charcoal stoves.

Each carbon credit represents a ton of climate-warming carbon dioxide or its equivalent, either removed from the atmosphere or prevented from entering it in the first place.
