Emissions targets rather than taxes are the best way to reduce greenhouse gases at airlines, according to Virgin Airways founder Richard Branson, who urged world leaders gathered in Copenhagen to set those targets on Friday "so that we know where we stand and we can get on with it and make sure this world is back on track again." Branson said taxes would be self-defeating because "if you strip money from the airlines, then they will have less to invest in new planes and new technology." Airlines should push to convert to biofuels by 2020, Branson said, and plane makers should help by building lighter aircraft. "Airbus and Boeing [need] to be building new carbon-composite planes, not just parts," he said.
