prevention principle

The prevention principle in environmental law emphasizes that it is more effective and less harmful to prevent environmental damage before it occurs, rather than reacting to it afterward. This principle is fundamental to laws governing hazardous waste and pesticide use. It was a cornerstone of the Basel Convention, aiming to reduce hazardous waste production and illegal dumping.1

The precautionary principle, closely related, suggests taking preventative measures when there's a strong suspicion of potential environmental harm, even without full scientific certainty. This approach is used in international law, such as the Rio Declaration, and in policies concerning endangered species and genetically modified organisms. While valuable, critics note it can sometimes lead to overly risk-averse policies in situations with significant scientific uncertainty.23
