Taking stock of the precautionary principle since 2000

The precautionary principle is supposed to enable decision-makers to adopt precautionary measures even if scientific uncertainties about environmental and health risks remain. However, opinions about the precautionary principle are divided. To some, it is unscientific and an obstacle to progress. To others, it is a necessary tool to protect human health and the environment.

Case Study 4: Neonicotinoid insecticides

In Europe, hundreds of different pesticides are allowed in farming to control fungi (fungicides), weeds (herbicides) and plague insects (insecticides) that may harm the crop. Among them are Neonicotinoid insecticides (in short: neonics) that, due to the risk they pose for the environment and pollinating insects in particular, are regulated through the precautionary principle.
