Assessing the Environmental Impact of Car Choices

In this episode, I’m joined by Hannah Ritchie, senior researcher at Our World in Data and author of Clearing the Air. We dive into the data behind climate change, exploring what’s driving it, how solutions are developing, and why optimism is not misplaced.

Hannah breaks down the role of food, energy, and industry in emissions, explains where media narratives can create “climate whiplash,” and shares why imperfect solutions still move us in the right direction.

What We Cover

• Food, diet, and agricultural emissions
• Renewable energy vs fossil fuels
• Electric vehicles and battery concerns
• Aviation’s role in climate change
• AI’s growing energy footprint
• Individual choices vs systemic change

This conversation is a reminder that climate change is solvable, and that progress is already underway.

You can connect with Hannah Ritchie on Bluesky and through her newsletter, Sustainability by Numbers, or explore her work at hannahritchie.com and Our World in Data.
