Sasol pollution linked to premature deaths, study suggests

South African energy company Sasol faces mounting climate scrutiny after researchers tied emissions from its flagship Secunda plant to about 1,000 premature deaths annually. A study by the Centre for Research on Energy and Clean Air, a Finland-based nonprofit, found emissions from the plant had an overall health cost of nearly $1 billion. The findings underscore the tension in Africa’s biggest economy between its climate commitments and its reliance on Sasol — widely recognized as the world’s largest single-site emitter of greenhouse gases — for macroeconomic stability.

Last month, regulators said they were preparing to reinstate criminal charges against Sasol after alleged unlawful discharges of chemical waste into a river. Sasol denies wrongdoing. A separate study from the University of Cape Town, meanwhile, warned that a rushed closure of the Secunda as part of the green energy transition could wipe $550 million off South Africa’s $400 billion economy.

South Africa remains locked into coal, which provides more than 80% of its power, making Secunda and the wider coal-fired power station fleet both national economic assets and global climate liabilities.
