A brand new report released by the Pew Center for Climate Change projects a positive outlook amid growing concerns emissions of greenhouse gases (GHG) from transportation. The report, co-authored by David L. Green and Steven Plotkin, looks at the numbers behind GHG emissions along with methods for reduction, and alternative fuels.

Below is an excerpt from the executive summary:

"This report examines the prospects for substantially reducing the greenhouse gas (GHG) emissions from the U.S. transportation sector, which accounts for 27 percent of the GHG emissions of the entire U.S. economy and 30 percent of the world’s transportation GHG emissions. Without shifts in existing policies, the U.S. transportation sector’s GHG emissions are expected to grow by about 10 percent by 2035, and will still account for a quarter of global transportation emissions at that time. If there is to be any hope that damages from climate change can be held to moderate levels, these trends must change."
