The Environmental Protection Agency (EPA) is facing a lawsuit filed by a community group and questions from a US senator over the agency's approval of fuels made from discarded plastic under a program it touted as climate-friendly".

The new scrutiny is in response to an earlier investigation by ProPublica and the Guardian that revealed the EPA approved the new chemicals even though its own scientists calculated that pollution from production of one of the plastic-based fuels was so toxic that one in four people exposed to it over their lifetime would be expected to develop cancer. That risk is 250,000 times greater than the level usually considered acceptable by the EPA division that approves new chemicals, and it's higher than the lifetime risk of cancer for current smokers.
