South Africa’s “laughably weak and ineffective” carbon tax regime is no disincentive to carbon-intensive businesses, such as integrated chemicals and energy company Sasol, environmental activist organisation Greenpeace Africa climate and energy campaigner Thandile Chinyavanhu tells Engineering News. She argues that the exemptions built into the system are allowing the JSE-listed group to avoid billions of rands in taxes yearly, adding that Sasol is considered to be South Africa’s second-largest emitter of greenhouse gases (GHG).
