Sasol’s appeal of the National Air Quality Officer’s (NAQO’s) July 11 refusal to approve an alternative approach for measuring the sulphur dioxide (SO2) emissions from the 17 coal boilers at the group’s Secunda complex, in Mpumalanga, is being strongly opposed by shareholder activism organisation Just Share. Sasol lodged an appeal with Environment Minister Barbara Creecy on July 30, after the NAQO declined its application to have the boilers’ SO2 emissions regulated, from April 1, 2025 onwards, using a load-based emission limit rather than the prevailing concentration-based emissions limit used for setting Minimum Emission Standards (MES).
