Host Seth Scott interviews Cathy Bebelman.  

Cathy is the Chief Scientist: Head of Science and Sustainability with Auckland Transport in New Zealand. Cathy has an extensive background in the environmental impacts of infrastructure and transport networks, working as a researcher and consultant in the public sector for over 25 years. 

She advocates for a holistic approach to the management of climate and the environment.  Auckland Transport made changes to their approach to transport after the 2023 Auckland Anniversary and Cyclone Gabrielle storms.   

This month they published their Climate Adaptation Framework and Action Plan 2025 - https://at.govt.nz/media/iqebfs0r/at-climate-adaption-framework-and-action-plan.pdf   [https://at.govt.nz/media/iqebfs0r/at-climate-adaption-framework-and-action-plan.pdf]  

The storms caused 2,000 landslides across the region at a cost to repair of $360 million. Cathy discusses how they worked to resolve this as well as how their budget might need to change to incorporate climate related storm damage to come.  That hasn't slowed down AT's electrification efforts. 

Aucklanders now enjoy a fully electric train system, the largest electrified bus fleet in the South Pacific, and new electric ferries on the water.   

And there's a lot more to look forward to.

S3E2 - Institute for Sustainable Infrastructure w/ Anthony Kane

Host Seth Scott interviews Cailin Slattery, Assistant Professor of Economics at the University of California, Berkeley Haas School of Business. Cailin brings us her findings from the paper “State Capacity and Infrastructure Costs” (co-authored with Yale Law School Professor Zachary Liscow and Columbia University's William Nober). Key findings of the report:   

👉 One addtional transport employee per 1,000 residents is correlated with 26% lower costs at the project level.  

👉 Experience engineers and professionals in the upper 75th percentile are associate dwith 14% rductions in project-level costs. 

👉 A single high-quality engineer can save a project up to $750,000 a year 

👉 The departure of an experienced engineer can result in cost increases equal to six times their salary. This is equally true if they leave for retirement, the private sector, or an overseas position. 

👉 For all these reasons, proponents should be willing to pay up high-quality engineers up to $300,000 per year, well over twice the industry average, to reain that knowledge in house, in the pipeline, and available to the next generation of professionals.

S2E7 - Beca's Circular Design Framework w/ Tania Hyde

During our interview with Lisa McLean, Managing Director and CEO of Circular Australia, we learned of some of the impressive circular initiatives happening in Australia, such as: 

- The importance of building circular "precincts", a place to keep resources in circulation locally. 

- The new ISO 59000 Global Framework for implementing circular economy principles 

- Several of Circular Australia's members doing amazing things, such as Allmould's collection of St. Vincent's Hospital's plastics waste to form new plastic blocks for use in the wind industry.  

Lisa is the Managing Director and CEO of Circular Australia, an independent peak body for circular economy innovation. She has successfully advised industry and governments to bring market change with new policy frameworks and regulations enabling the circular zero-carbon economy over the next 20 years. Formerly a political journalist, Lisa was also founder of the carbon accounting service Carbonwise and helped establish the Clinton Climate Initiative. Lisa is leading the transition to a zero-carbon circular economy in Australia.

S2E6 - Australia's Circular Economy w/ Lisa McLean

Today we're touring one of Waste Management's recovery centres in Auckland and meeting with Ingrid Cronin-Knight, Chief Growth and Sustainability Officer at Waste Management New Zealand. We talked to her about how to turn waste into gold.  

We learned a lot from our visit. Recycling isn't easy but when done right we can recover a good portion of our infrastructure materials, especially concrete, steel, gib, and timber. We also learned that the simple act of higher waste levies encourages more recycling and more emphasis on designing out waste. We need  more facilities like to take the load off landfills.   

Your impact at work far outweighs your impact as an individual. Not much of what you throw out of your home gets recycled. Even if you're sorting your food waste, green waste, glass, and plastics, the vast majority of what you throw out goes straight to landfill. That's what makes specifying recycling on infrastructure projects so important. Since concrete, steel and asphalt are the easiest to recycle, our work can make a massive impact.
