Scandinavian airline SAS has found a viable way to cut down on greenhouse-gas emissions and fuel costs: fly slower. The airline has been testing slower speeds since early 2006, and says it has saved some $12 million in fuel costs since then. And have no fear about missing your connection; hitting the brakes adds mere minutes to travel time. SAS hopes that implementing the slowdown strategy throughout its fleet will boost its green image; it was also one of the first airlines to give passengers the option to offset their carbon emissions when purchasing a ticket.
