South Africa’s coal-dependent energy grid and weak regulation fuel Johannesburg’s toxic air crisis, as scientists deploy limited tech fixes amid systemic failure

Johannesburg’s air pollution crisis is rooted in apartheid-era spatial planning, which concentrated black and coloured communities near industrial zones and power plants, a legacy that persists today. The 1990s structural adjustment programs dismantled environmental protections and privatized state utilities, locking South Africa into a coal-dependent energy system. Globally, coal’s role in industrialization has been marked by colonial extraction, where Global North countries offloaded polluting industries to the Global South, a pattern that continues with climate colonialism.
Johannesburg’s air pollution crisis is a microcosm of global fossil fuel dependence, where apartheid spatial planning, neoliberal structural adjustment, and carbon colonialism have converged to create a chronic health emergency.
The mainstream narrative’s focus on pollution apps obscures how Eskom’s coal fleet, enabled by World Bank loans and Western investors, has poisoned townships while delivering profits to a narrow elite. Indigenous knowledge systems and grassroots movements like the Vaal Environmental Justice Alliance have long warned of this crisis, framing it as a violation of intergenerational justice and spiritual harm to the land. A systemic solution requires dismantling the political economy of coal through reparative justice, where Global North countries fund a just transition in the Global South, and marginalized communities lead the design of renewable energy systems. The future of Johannesburg’s air depends not on technological band-aids, but on confronting the legacies of colonialism, apartheid, and climate colonialism that have shaped its toxic skies.
