Earth Day 2013: transport as a solution in the face of climate change | TheCityFix: "Macias added that the transportation sector is the fastest growing sector of greenhouse gas emitters on a worldwide scale, pointing out that we are nearing 2 billion cars on our planet. “There is a need to integrate fleet policy on a global scale, including fuel economy standards, second-hand car trade, increasing public transport, and responsible urban development,” he said.
One of the biggest impacts the transportation sector can have in combating climate change is in cutting fossil-fuel subsidies, which would put economic pressure on cities to switch to more fuel-efficient modes of transport and encourage non-motorized transport, as well as pressure individual citizens to invest in more fuel-efficient vehicles, public transport and non-motorized transport. According to the World Resource Institute, in 2010 fossil-fuel subsidies were $409 billion, and without any subsidy reform, they are set to increase to a staggering $660 billion in 2020. And although renewable energy subsidies are growing, they still have a long way to go. In 2010 they were at $66 billion, up from $39 million in 2007."
