Sep 4, 2026 · 50m

Summary

Social psychologist Elizabeth Dunn and climate expert Jiang Zhao discuss their book "Leave the Lights On," arguing that joyful, high-impact actions are more effective for fighting climate change than guilt-driven habits. They debunk myths about trivial eco-choices, like turning off lights, and highlight sustainable behaviors that boost happiness, such as eating maple syrup, taking nonstop flights, and spending money on others. The episode emphasizes that individual actions, when framed positively, can reduce emissions while enhancing personal well-being and influencing others.
