Reducing transport emissions: lessons from a career

Margarita Parra and I discussed lessons from her 8 years directing William and Flora Hewlett Foundation grant-making aimed at reducing transportation-related air pollution and greenhouse gas emissions.

The interview was prompted by an article Margarita wrote for the Foundation’s website to reflect on and share lessons learned from her work there
The article was also picked up (and adapted slightly) by WRI’s the CityFix blog

Margarita is worth paying attention to on this issue given her long track record of working on it through several relevant organizations. Before Hewlett Foundation, her experience included ICLEI's Ecomobility programme. She is also a Member of the Board of Directors for the Partnership on Sustainable, Low Carbon Transport (SLoCaT). 

Here is how you can digest my discussion with Margarita: 
  • The best way is to LISTEN to the 31 minute audio with the player above. 
  • Or subscribe to the audio podcast if you are a podcast listener (search for 'Reinventing Transport' in your podcast player app or click the symbol that looks like a wifi icon in the player above).
  • There is no long article this time. Just some very brief highlights below. So please do listen or read Margarita's original article that prompted our interview.  
  • The Youtube version is at the end of this post (scroll to the bottom).
  • My Patreon patrons will be able to download a full transcript. 

Some brief highlights from the conversation

  • Margarita described how the Hewlett Foundation's grant-making on transport emissions works. 
  • Why transportation needs to be an increasingly important part of emissions reduction efforts. 
  • The "two-part strategy" that Margarita applied to this issue at the Foundation: 1. decarbonize and 2. optimizing to get more mobility of people and goods with fewer vehicles. 
  • Debate over which should be primary. Why both are needed. Why she (and many) are attracted to 2. But how her analysis showed that 1. offers faster results right now, especially given technology advances. 
  • Some of her favorite grantees and projects. These includes projects by ITDP and WRI Ross Center for Sustainable Cities, such as the Rickshaw Rising Challenge
  • Rapid change and innovations, such as IT enabled phenomena such as ride-hailing and dockless bikesharing among others, and how they offer both promise and risks. 
  • The state of the transition to Electric Vehicles: accelerating but still largely policy-driven not yet a market-driven process.
  • Why co-benefits of carbon emission reductions are crucial, since they address people's immediate priorities.

Save Manila's (mostly informal) public transport!

Metro Manila depends on informal, lightly-regulated public transport which now faces a catastrophe as a result of this pandemic. The Mobility Coalition, an alliance of eight Metro Manila transport advocacy groups, has ideas on what to do. I spoke with Robie Siy who is active in the Mobility Coalition and who writes the weekly Mobility Matters column for the Manila Times.   [Scroll to the end for more details on Robie, Mobility Matters and the Mobility Alliance.] Scroll down for highlights of our conversation or listen with the player below.

I am working to map global "sustainable transport" advocates (for want of a better phrase).  You can help! Submit suggestions or corrections via this google form . Here is the map so far. Please explore it and help me improve it.

Transport-based City Types and their Trajectories

I want to help you get perspective on your city and its transport system with the help of simple city types based on their dominant transport modes, such as Walking Cities, Transit Cities, Bus Cities, Motorcycle Cities and Car Cities. This way of thinking about cities is a  heuristic  (an imperfect mental model or technique that is nevertheless good enough to be helpful). And it obviously is imperfect. For example, real cities often have various modes of transport, and modern cities are really all some kind of hybrid city type. But it is still useful, especially if we add the idea of a Traffic Saturated City , which is a very different beast from a Car City. It is important for change-makers in Traffic Saturated Cities to be aware they are not in automobile dependent cities yet. Options for digesting this:  Read the brief article below and study the diagrams. They complement the podcast.  For more depth, LISTEN to the 37 minute audio with the player above.  A full transcri
