In this week’s episode, host Daniel Raimi talks with Nafisa Lohawala, a fellow at Resources for the Future, about sustainable aviation fuels (SAFs). Lohawala discusses the climate impact of the aviation industry, different types of SAFs, and the reductions in greenhouse gas emissions that SAFs can help achieve. Lohawala also discusses policies that support the adoption of SAFs, including international agreements and financial incentives in the United States.

What Are Sustainable Aviation Fuels?, with Nafisa Lohawala

This paper examines whether major corporate customers curb corporate carbon emissions along the supply chain. We show that suppliers with a more concentrated customer base have significantly lower carbon emissions. The results are robust to alternative measures of carbon emissions and customer concentration, alternative sample, alternative explanation, and various approaches to mitigate endogeneity concerns. The effect is more pronounced when major customers have made emission-reduction commitment, when they are exposed to greater climate regulatory shocks and risks, and when they become more concerned about regulatory scrutiny. Moreover, the curbing effect of major customers on supplier carbon emissions is stronger when customers have lower switching costs and stronger bargaining power over suppliers. We show that one way through which suppliers reduce emissions is by adopting green technologies. Our study highlights the role of major customers in facilitating the transition to a low-carbon economy through decarbonization along the supply chain.

#16 Breakdown: Major customers and carbon footprints along the supply chain

In this week’s episode, host Kristin Hayes talks with Danny Richter, director of the Pricing Carbon Initiative, about the existing suite of carbon pricing policies, a set of climate policy tools designed to reduce carbon dioxide emissions by requiring companies and other entities to pay for each ton of carbon dioxide they release into the atmosphere. Richter evaluates the international and domestic approaches to carbon pricing policies, explaining their history, uptake, and longevity. Richter highlights the flexibility of carbon pricing programs—which allows policymakers to tailor the sources and investment of revenues from carbon pricing to their unique policy priorities—as key to the long-term success of these programs. Richter then outlines shifting attitudes toward carbon pricing in the United States, highlighting how successful cap-and-invest initiatives emphasize the economic advantages of these policies while delivering climate benefits.

Carbon Pricing Is Dead. Long Live Carbon Pricing!, with Danny Richter

In this week’s episode, host Daniel Rami talks with Heather Zichal, global head of sustainability at JPMorganChase, about the role of financial institutions in the energy transition. Zichal explains how she has advanced climate policy goals from positions in the United States Congress, the executive branch, nonprofits, and the financial sector. From these diverse perspectives, Zichal outlines the opportunities and challenges for climate-policy stakeholders as they navigate an uncertain political environment. Zichal highlights how financial institutions support the energy transition through green finance commitments, supporting clients’ sustainability goals, and investing in emerging technologies to support the world’s energy needs. Zichal underscores the importance of promoting climate solutions that focus on long-term value in the context of commercial and sustainability goals and that balance environmental and business priorities.

Financing the Energy Transition amid Unpredictable Climate Policy, with Heather Zichal

Welcome to Overdrive, the show that dives into the quirks, questions, and cultural shifts shaping how we move. Host David Brown is joined by Brian Smith, transport planner and original Overdrive contributor, for a jam-packed episode that blends industry news, thoughtful critique, and cheeky observations.

🎙️ This Week on Overdrive:

📊 1. J.D. Power’s 2025 Vehicle Quality Study – More Tech, More Trouble
While overall vehicle quality has ticked up slightly, touchscreen systems remain the most complained-about feature in new cars. David and Brian discuss why the removal of physical buttons frustrates drivers and how infotainment failures are now a core part of early car returns.

🔌 2. Plug-in Hybrids: The Worst of Both Worlds?
Despite their eco-friendly label, plug-in hybrids are proving problematic. Many owners don't plug them in, defeating their purpose and contributing to mechanical complexity without the payoff. We ask: are PHEVs just a stopgap that never lived up to their promise?

🛴 3. World’s Fastest Scooter – Innovation or PR Stunt?
A British startup wants to break the 160km/h mark with a high-speed e-scooter. But is this headline-grabbing move advancing micromobility—or undermining it? We explore why promoting e-scooters with speed risks repeating the mistakes of muscle car marketing.

⚡ 4. EV Ambitions Stalling? Inside the Industry’s Electric Pause
Volvo, GM, and others are hitting the brakes on US EV rollouts. We unpack the influence of changing subsidies, global tariffs, and consumer hesitancy—especially at the luxury end—and ask whether retro-styled EVs like the VW ID. Buzz are moving the market forward or clinging to outdated dreams.

🚚 5. Commercial Fleets & Carbon: Australia’s Net Zero Blind Spot
With commercial vehicles making up nearly half of new car sales and one-fifth of emissions, Australia’s electrification of its fleet is lagging badly. We examine five key reasons—from infrastructure gaps to outdated procurement mindsets—and highlight smart fixes like shared depot charging.

📬 6. Feedback from France: A Hot Hatch Lives!
A French listener shares his love for the Hyundai i20N—proof that the spirit of manual, high-revving hatches still has global fans. We celebrate a rare survivor in an increasingly homogenised auto market.

🎨 7. Austin-Healey Car Show: Colour, Character & Noise
David attends a vintage Healey event marking Donald Healey’s birthday. From two-tone colour schemes to the visceral sound of tuned exhausts, we reflect on an era when you really had to drive the car—and feel every bump and brake fade along the way.

🛻 8. Triton Road Test & The Ute Culture Problem
We take the Mitsubishi Triton GSR off-road and discuss how it stacks up against flashier competitors like the Raptor. Beyond the specs, we confront how oversized, aggressive utes are shaping driving behaviour, image, and even pedestrian safety—especially when piloted by P-platers with something to prove.

💡 Themes woven throughout:

Are EVs being sold with outdated emotional appeals?

How nostalgia can cloud smart design

Fleet electrification as climate policy in practice

Why engineering videos still miss the human story

The social impact of high-performance design choices

Verdaderas soluciones climáticas están debajo de nosotros

In this week’s episode, host Daniel Raimi discusses carbon removal with Jennifer Wilcox, a professor at the University of Pennsylvania who recently coauthored a paper titled, “Elevating Carbon Management: A Policy Decision-Making Framework and Rubric for the 21st Century.” Wilcox discusses the existing gaps in current policies related to carbon removal and important considerations when amending and creating new policies. She also addresses the recent change to the 45Q subsidy (originally included in the Inflation Reduction Act of 2022 and revised by Congress in the budget reconciliation bill signed on July 4, 2025), assessing how the updated tax break offers incentives for carbon removal.

In this episode of Knowledge Counts, host Wendy Hobbs speaks with Ayo Daniel Abiola, PQS, Manager of Hanscomb's Saskatchewan office, about carbon emissions in the construction sector.

Knowledge Counts: Carbon Emissions in the Construction Sector with Ayo Daniel Abiola

In this week’s episode, host Daniel Raimi talks with Vivek Srikrishnan about factors that contribute to sea level rise. Srikrishnan, an assistant professor at Cornell University, describes the difficulties involved in analyzing the impact of the complex factors related to climate and climate change, which in turn lead to uncertainties in projecting the extent of future sea level rise. In a new publication, Srikrishnan and coauthors model different scenarios that capture those uncertainties. Srikrishnan also points out how short-lived greenhouse gases can lead to greater ice melt compared to more persistent greenhouse gases, as well as the irreversible nature of ice melts.
