Talking Headways Podcast: Measuring Carbon Emissions at Street Level

podcast icon logo

Dr. Kevin Gurney is a carbon cycle scientist at Arizona State University. I recently came across an article in Nature about his work measuring carbon emissions from mobile sources at street level, and I wanted to find out more.

On the podcast, I asked Dr. Gurney why cities are important to climate change, and why political boundaries make it difficult to collect data. And we discussed why measuring emissions matters not only for climate change, but also policy arenas like transportation planning and housing.

Dr. Gurney also peers into his crystal ball to assess whether we’ll have the tools to detect something like the Volkswagen emissions scandal in the future.

Join us for a fun discussion about cities, emissions, and data collection at the street, the block, and the city level.

    Did anyone listen to this and can tell me if they addressed the question of on-street bike boulevards versus separated trails? I prefer to take routes that snake away form traffic as I can assess the pollution levels not with my smartphone but with my nose.

  • The Overhead Wire

    We didn’t address that question though there has been some research in that field. We were mostly talking about measuring emissions at the street level but for a regional scale analysis.

  • Joe Linton

    Wow (minute 13.40 quoting Jeff Wood’s statement) – 47% of L.A. greenhouse gas emissions are from road vehicles! Any directions on where I can find the source for this data? (Am curious if it’s city, county, metropolitan area.) In the meantime I’ll quote the podcast.

We Need a Complete Solution to Climate Change

|
This morning, Jeff Wood at The Overhead Wire points us to a newly released measure of CO2 emissions from the Center for Neighborhood Technology (which just won a 2009 MacArthur Foundation Award for Creative and Effective Institutions, BTW). He says maps like these help to show why changing land-use patterns is vital in the fight […]

Can We Bike Our Way to a Stable Climate?

Crossposted from the Frontier Group.  Earlier this week, I had the chance to talk about the role of bicycling in addressing climate change at the National Bike Summit in Washington, D.C., sponsored by the League of American Bicyclists. The conversation was framed around the Paris climate agreement – the pact signed by 195 nations in December […]

Yes, Local Transportation Agencies Can Measure Their Climate Impacts

|
It’s going to be a tough sell for those who claim that greenhouse gas performance measures for transportation can’t possibly work, when plenty of transportation agencies say it would be no problem. That’s according to transportation officials in several regions across America who responded to a survey commissioned by the Natural Resources Defense Council. The responses were […]

Talking Headways Podcast: A Better Measuring Stick for Transportation

|
Kevin DeGood of the Center for American Progress and Deron Lovaas of NRDC join the podcast this week to talk about rules proposed by U.S. DOT to measure congestion and greenhouse gas emissions. These rules matter because they’ll create new feedback loops for transportation agencies — the feds can create incentives to reduce car trips and carbon pollution if […]
