The Democratic Republic of Congo (DRC), a leading cobalt supplier, is grappling with environmental and human rights issues due to industrial cobalt mining. A report by RAID and AFREWATCH reveals that toxic pollution from cobalt mining in and around Kolwezi, the heart of DRC's cobalt industry, is devastating the lives of hundreds of thousands of Congolese people. The report challenges the narrative of 'clean' and 'sustainable cobalt' promoted by multinational mining companies. It highlights the impacts of water pollution, including health issues among local residents and destructive consequences on local ecosystems and agriculture. The report underscores the urgent need for sustainable practices and effective regulations to protect the DRC's communities and environment and calls for companies buying cobalt to ensure responsible sourcing.
