Season 8 of Fox's 24 debuted last night and agent Jack Bauer is, once again, mean and green. For the past few years the show has looked to reduce its carbon footprint and is doing so again in season 8. Kiefer Sutherland tells MNN: When we started around season four, the goal was to be able to make 24 and not leave a carbon footprint....I don’t know if that’s possible because we have to drive to work, but\nall of the trucks we’re using are hybrids. We’re not using gas fuels\nand there are a lot of things being done within the office and the\nproduction building as well. We’ve made a marked improvement from where\nwe were in season one.
