Degrees of Change: Transportation. December 13, 2019, Part 1

Transportation—whether it be your car, aircraft, cargo ships, or the heavy trucks carrying all those holiday packages—makes a big contribution to the world’s CO2 emissions. In the U.S., the transportation sector accounts for some 29% of the country’s emissions, according to Environmental Protection Agency data. And despite the Paris Agreement mission to decrease global emissions, demand for transportation around the world is on the rise—and with that increased demand comes increased energy use. Air travel is growing at a rate of 2-3% a year, for instance—a trend that could cause the emissions effects of air transport to almost double by 2050.

But there are some initiatives and technologies that aim to alleviate the energy costs from this transportation glut.

In this chapter of our Degrees of Change series, we’ll talk about transportation, and some of the technology and policy changes that could be made to make getting around more sustainable. Daniel Sperling, founding director of the Institute of Transportation Studies at the University of California, Davis joins Ira to talk about personal transportation in the U.S., and how individuals get around. We’ll talk with Steven Barrett, director of the Laboratory for Aviation and the Environment at the Massachusetts Institute of Technology, about greener flying. And Rachel Muncrief, of the International Council on Clean Transportation, joins the conversation to talk about improving heavy vehicles like buses and cargo trucks.

And, as the climate crisis deepens, the effects are increasingly ravaging developing nations, which had little or nothing to do with warming the planet. Now those nations are asking industrialized countries to help them deal with the damage—but major powers, like the United States, don’t want to pay up.

Those tensions were playing out this week and last at the UN Climate Change Conference in Madrid, and New York Times climate reporter Kendra Pierre-Louis joins Ira to catch us up on that international drama.
