According to a new study, Eskom is now the world’s most polluting power company.

The survey by the Centre for Research on Energy and Clean Air shows Eskom emits more Sulphur dioxide than the entire power sectors of the EU, the United States and China.

Eskom spokesperson, Sikonathi Mantshantsha has meanwhile said the power-utility is embarking on a programme to retire its coal-fired power stations.

He says the utility is also working to reduce emissions to acceptable levels.

In 2015, the six economies with the highest levels of Sulphur dioxide emissions were India, the US, China, Saudi Arabia, South Africa and the EU.
