Emily Castor Warren, a former executive at ridehailing company Lyft and shared scooter company Lime, and a leading expert in emerging mobility models, has joined national transportation planning firm Nelson\Nygaard as principal and director of policy.
Warren, a pioneer of regulatory frameworks for new mobility services, will head up the firm’s new policy practice. Warren’s comprehensive knowledge of transportation tech platforms and local, state, and federal policy will help Nelson\Nygaard clients craft creative strategies to govern new technologies and build livable cities that put people first. She will be based in Oakland.
“I’ve spent the last decade bringing to market new transportation choices designed to make cities more sustainable,” Warren said. “But technology alone can’t solve the transportation problems cities face, and smart policymaking is needed to guide the next phase of mobility innovation. I’m honored to join Nelson\Nygaard’s outstanding team to help governments implement bold policies that harness the benefits of technology and shape it for the better. I look forward to working with our partners to champion systemic policy change to make cities more livable for all.”
“Across North America, local, state, and even federal government agencies today face enormous pressure to solve rising transportation challenges like congestion, traffic fatalities, climate change, infrastructure funding, and equitable mobility access in an environment of accelerating technological change,” says Leah Riley, managing director of Nelson\Nygaard. “With Emily’s policy leadership, in conjunction with our firm’s thriving Emerging Mobility practice and transportation planning and engineering teams, we’ll be able to guide governments in tackling these challenges, from policy development to implementation.”
In her past policy leadership roles at Lyft and Lime, Warren served as a strong internal advocate for the concerns of cities, launching Lyft’s first partnerships with public transit and regional planning agencies, pushing for ridehailing fleet electrification, and calling on the scooter industry to support open-source data-sharing with regulators.
Since leaving the private sector, she has focused on public interest advocacy to redesign cities around people, both through her service as a volunteer board member with organizations like the LivableStreets Alliance and the Shared Use Mobility Center and as a grassroots bike, transit, and housing activist in her local community.
Warren’s first day on the new job at Nelson\Nygaard will be February 3.
“We’re in a new era of mobility, and that’s really exciting but also not without its challenges,” said Riley. “The pace of technological advancement is so rapid that many of our clients are only able to react, and they often find they don’t have the regulatory tools or policy expertise to make these technological advancements work for them—to help make their communities more livable, equitable, and sustainable. Emily’s guidance will give them more control over shaping their future in line with their community values.”
