I thought the issue was not the CO2 they emit out the front but the methane(CH4) emitted from the other end. Methane apparently does an even better job than CO2 of keeping the heat in. The Royal Society's Summer Science Exhibition a few years ago featured the work of some scientists measuring the impact of different feeds on the amount of methane produced.
