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:

  • 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.

Singapore Urban Transport: The Warts-and-All Story

Singapore's National Day is this week (9 August). So I decided to share Singapore's urban transport story - or my slightly  unusual take on it .  It is   a unique city in various ways but its urban transport policies are well worth your attention even if you don't live in Singapore. This is a warts-and-all version of the story, and it is my own view, not any kind of official one. It's also a little wonkish in parts. [Hi all you policy wonks!] But I hope to keep your interest with some surprising twists, such as: Why was the bus-only public transport system in an awful state by the early 1970s? If the buses were awful in early 1974, how was Singapore able to impose drastic increases to the cost of motoring in 1975? You will have guessed that the buses must have been drastically improved in 1974/75. But how was that achieved? Singapore urban transport enjoyed success through the 1980s and 1990s but its core social bargain (cars for the rich; decent but bas

Shaping public transport

If you care about promoting public transport, you need to understand the key choices about organising and regulating it. These choices shape the industry and they really matter. This is NOT just about privatisation versus government operation. It is more interesting than that. This edition of Reinventing Transport shares the key alternatives and gives a sense of what's at stake. The focus is buses but most of the ideas also apply more widely.

If you want more gory details, then follow the links right at the end of the article. It may seem dull but bus regulation is important!
