There are systemic flaws in the system for investigating oil spills in the Niger Delta: the outcome of these investigations lacks credibility. The human rights consequences are serious. The lack of transparency around this investigation process is a further factor that contributes to heightened tensions in the Niger Delta. With regard to Shell, reviewing all available data this report has built up a picture of a company whose claims about its environmental impact in the Niger Delta are frequently untrue. This report also raises serious concerns about the scale of oil spills from Agip’s facilities.
