Environmental justice group groundWork, represented by the Centre for Environmental Rights, has launched High Court proceedings against Environmental Affairs Minister Nomvula Mokonyane and President Cyril Ramaphosa and is asking the court to set aside government’s plan to double the amount of sulphur dioxide (SO2) polluters are allowed to emit. The weakening of the standards will allow all coal-fired boilers to emit double their previously allowed SO2 pollution from April 1, 2020, states groundWork.
