Transit covers both human transportation (commuting and travel) and the transportation of goods around the world. It represents one of the largest sources of carbon in human society, from cars and trucks, to boats, to planes, to trains—it all costs energy, and the bulk of that energy, currently, comes from fossil fuels.
