Eskom Holdings Under Fire for World’s Worst Emission Sites of Toxic Pollutants: What You Need to Know

Eskom Holdings SOC Ltd., South Africa’s state power company, has responded to a Greenpeace report that accuses it of operating some of the world’s worst emission sites for toxic nitrogen dioxide and sulfur dioxide. The Major Air Polluters in Africa report, released in collaboration with the Centre For Research on Energy and Clean Air, claims that coal-fired plants operated by Eskom account for five of the world’s 10 biggest single-source nitrogen-dioxide emission sites and two of the 10 worst sulfur-dioxide sites.

In response to the report, Eskom stated that the findings were based on satellite interpretation of high levels of nitrogen dioxide and sulfur dioxide in the atmosphere, linking them to ground-level health impacts. The company maintains that at ground level, its plants mostly comply with South African nitrogen-dioxide emission levels, with any non-compliance being attributed to nearby vehicle traffic and other industrial sources.

South Africa heavily relies on coal for more than 80% of its electricity generation, leading to some of the world’s worst air pollution. Despite having emission standards that are less stringent than those in China and India, enforcement is lacking. However, Eskom noted that its newest coal-fired plants have low NOx burners to reduce nitrogen dioxide emissions and flue-gas desulfurization units to reduce sulfur-dioxide emissions. They also pointed out that equipment at Kusile is currently bypassed due to an accident but they are working towards fixing it as soon as possible.
