The biggest greenhouse gas emitter in the United States is no longer the power sector. It’s something all of us make choices about every day – transportation. There’s a big difference in emissions between driving a pickup truck that gets 17 miles per gallon and an electric vehicle with zero emissions, or skipping the car altogether and taking public transit or walking.

A major report released Monday by the Intergovernmental Panel on Climate Change, involving scientists from around the world, gauges the world’s progress so far at stopping climate change. The results are sobering, but the report also points to innovations that have the potential to transform the world for a safer future. Alan Jenn, a transportation specialist at the University of California, Davis, who contributed to the IPCC report, explains four powerful trends in transportation that could greatly reduce the sector’s greenhouse gas emissions – three of them involving human choices and behavior.

Revolutionary changes in transportation, from electric vehicles to ride sharing, could slow global warming – if they’re done right, IPCC says

A new international report on climate change finds rapid changes could cut emissions from transportation by 80% to 90%. Three behavior change trends could bring big improvements.
