The French government has postponed a ban on throwaway plastic cups by four years to 2030 because of difficulties finding alternatives. The ban was meant to start on January 1st. But the ministry for ecological transition said the "technical feasibility of eliminating plastic from cups" following a review this year justified pushing back the deadline. It said in an official decree that a new review would be carried out in 2028 of "progress made in replacing single-use plastic cups".
