Jeffrey Tumlin

Jeffrey Tumlin is an owner and sustainability practice leader of NelsonNygaard Consulting Associates, a San Francisco-based transportation planning and engineering firm that focuses on sustainable mobility. Over the past 19 years, he has led station area, downtown, citywide, and campus plans, and delivered various lectures and classes, in 20 U.S. states and five other countries. His major development projects have succeeded in reducing their traffic and CO2 emissions by as much as 40%, and accommodated many millions of square feet of growth with no net increase in motor vehicle traffic. These projects have won awards from the General Services Administration, American Planning Association, American Society of Landscape Architects, Congress for the New Urbanism, and Urban Land Institute. He got his driver’s license on the day of his 16th birthday, and while he loves driving, he does not like regulations and subsidies that hide the cost of other people driving in front of him.
