Data and the Future of Mobility: An Interview with Dr. Regina Clewlow

I recently got to sit down with Dr. Regina Clewlow, CEO of Populus, to talk about one of the most critical, yet unappreciated, pieces to improving our transportation system: data. Regina is one of the most respected people I know working in the new mobility industry. She has worked from all angles to improve how we get around, as a researcher in the academic world to leading roles in the private sector, including her current venture as the co-founder and CEO of the mobility data platform company, Populus. Here’s an edited transcript of a conversation we recently had about data and new mobility. Read more >

The California Air Resources Board (CARB) recently released a draft standard for transitioning the state’s transit buses to zero-emission battery or fuel cell technologies by 2040. This is great news for bus riders, bus drivers, local air quality, and tackling global warming emissions from the transportation sector.

Electric vs. Diesel vs. Natural Gas: Which Bus is Best for the Climate?

Battery electric buses – the people’s electric vehicle – are becoming more and more common. An increasing number of transit agencies – large and small – are making announcements about purchasing electric buses and putting them into operation.

The obvious benefit of electric buses is that they don’t have any tailpipe emissions. A question we often get at UCS is, “What about emissions used to generate electricity for electric vehicles?”

We answered this for buses charged on California’s grid and found that battery electric buses had 70 percent lower global warming emissions than a diesel or natural gas bus (it’s gotten even better since that analysis). So what about the rest of the country?

VW Settlement: A Needed Jolt for Electric Trucks and Buses, But More Is Needed

It has been nearly three years since the Volkswagen diesel scandal first broke. Since then, a handful of settlements have been reached, one of which provides states funding to offset the extra pollution emitted by defective Volkswagens.

A dozen states have recently finalized such funding plans and others are taking public comment on draft plans. These plans offset a majority of the pollution by providing financial incentives for the purchase of clean trucks and buses.
