In Brief: McDonald’s, which is known to produce more emissions than the country of Norway and which has been challenged to reduce its litter, has a new, but likely unpopular idea it may test in cooperation with Wales

That is to capture license plate numbers of customer cars and print them on meal bags, so those found littering after their McMeal can be identified. The Welsh government proposed this to other fast-food companies too, though it acknowledges whichever one goes first might find customers switching to others for privacy.
