Limiting climate change will require substantial and sustained reductions of GHG emissions.” (IPCC WGI, 2013.) The transportation sector accounts for almost one-third of all GHG emissions in the United States. Growing Cooler describes GHG emissions from transportation as comprised of a three… Read More
