Happy Earth Day, everyone! At DOT, we're working every day to better protect our planet -- and I know Fast Lane readers are, too.
America's transportation system accounts for 1/3 of our greenhouse gas emissions, more than 1/2 of our nitrogen oxide emissions, and almost 3/4 of our oil consumption. Greening that system is central to our nation's efforts to increase sustainability and reduce climate change.
That's why DOT is so focused on building more efficient, sustainable transportation. We're building marine highways that can cut greenhouse gas emissions; investing in a NextGen air traffic control system to lower aviation fuel consumption; building more capacity in our rail systems, which can be a more sustainable way to move both people and freight; and we're helping drivers save money and lower their carbon footprint, too.
