How much fuel is wasted and pollution caused by traffic backed up on a red light, while the green light lanes are empty?

About 1/4 of a mile from home there is a set of lights which had traffic detectors fitted. They worked as lights usually do when traffic was heavy but when traffic was light they detected approaching cars and turned the lights to green. So eminently sensible that the system has now been discontinued and the detectors removed
