The health burden from phthalates, bisphenols, pesticides and Pfas “forever chemicals” amounts to up to $2.2tn a year – roughly as much as the profits of the world’s 100 largest publicly listed companies, according to the report published on Wednesday. Most ecosystem damage remains unpriced, they say, but even a narrow accounting of ecological impacts, taking into account agricultural losses and meeting water safety standards for Pfas and pesticides, implies a further cost of $640bn.
