The relationship between transportation and climate change seems so obvious that it can be surprising to learn that federal policy on these two issues is completely separate and that few elected officials are even aware of the overlap. While President Obama made energy and climate change a focal point of his campaign, and then tried unsuccessfully to pass cap-and-trade climate legislation, he has not yet made the case that energy and climate should be important considerations in our future surface transportation policy. And even though Senate Committee on Environment and Public Works oversees not only climate but also highway funding, there has been little attempt so far by that committee to connect the two issues.
