--Consulting Associate Professor Karl Knapp,
Stanford University





"It's great to know that green cities leadership is right at our doorstep."

"Warren is the creator and lead author of SustainLane's US City Rankings. I've been in the sustainability business for 15 or 20 years now. And these types of rankings have been tried dozens and dozens of times and this in my opinion is the best one in terms of its rigor and how much care they've given to apples-to-apples comparisons. A lot of that comes from Warren's commitment."

--Steve Nicholas, Vice President of Climate and
Environmental Programs, Institute for Sustainable
Communities; former Seattle Sustainability Director

Ken's photo Kenneth Ott (Associate) is a sustainability metrics and trends researcher. Originally a suburbanite, he learned about sustainability firsthand while working in Asia, seeing how people in other countries managed their far less abundant resources -- primarily fossil fuel energy but also metal, wood, food and so on.

Throughout the region -- in Japan, China, Thailand and Cambodia -- Ken discovered the joys and perils of bicycling and taking the ferry, bus and train as socially ordinary transportation options for the majority of the populace. Walking of course, and water transport, proved the most sustainable of all transport modes. Elephants were novel, though not scalable, mass transit options. These experiences coupled with travel in Europe and South America have provided insight into how the US should improve its historically wasteful management of energy, water and other key resources to "set a better example for other countries" and strengthen its own economy.

Upon returning stateside Ken set out to start a restaurant grease collection company to produce biodiesel. Instead, he joined Bay Area Biofuel, an existing startup of like-minded entrepreneurs. Later, he sold his last remaining car in 2006. (At one point, Ken owned three cars and a moped.) Additional sustainability work has included stints as a consultant to the California Department of Conservation, consulting for a large real estate developer; and, US city sustainability research, project management, and reporting on sustainability trends for SustainLane by working with the largest US city mayors and their staff. Current and past side projects include: selling organic ice cream at farmers markets and forageSF, blogging about urban planning and suburban sustainability retrofitting efforts, operating a cycle rickshaw business in downtown Oakland and organic farming.

Ken earned his Bachelor of Arts degree at the University of California at Berkeley. He has been a Board Member for Urban Releaf, an urban forestry research and tree planting organization based in Oakland, California, since 2008.
