Energy and chemicals group Sasol reports that it has secured more than 100 000 carbon credits in a transaction concluded under the South African Carbon Offset Administration System (COAS), set up to facilitate the listing, transfer and retirement of such credits to offset carbon tax liabilities. In a statement the JSE-listed company said the transaction had been concluded with Bethlehem Hydro, a South African independent power producer (IPP), and that it was among the first concluded under COAS, which was launched earlier this year.
