Japan will provide supplies of clean coal to Botswana's Morupule B power station, which is due to come onstream in autumn 2013.
Botswana Minister of Minerals, Energy and Water Resources Ponatshego Kedikilwe told Sunday Standard that all possible remedies were put in place to lessen carbon emissions from the plant.
"We have been in constant touch with Japan, which produces large quantities of coal to produce electricity, but with little emission to cause health hazards to inhabitants," Kedikilwe said.
Work on the 600MW plant began at the beginning of 2010 and the plant is expected to be four times the size of the existing Morupule A power station.
Morupule A is the country's only power station since 1986 and the rest of the power demand is met by South Africa's Eskom.
The World Bank and African Development Bank will also provide funds for the project.
