Overview
- Stanford researchers, whose paper appeared Wednesday in Nature, tie emissions to economic losses and estimate damages at $10.2 trillion for the U.S., $8.7 trillion for China, and $6.4 trillion for the EU, with large impacts in India ($500 billion) and Brazil ($330 billion).
- They find future harm from past pollution is far larger because CO2 lingers and heat drags on growth, with a ton emitted in 1990 causing about $180 by 2020 versus about $1,840 by 2100.
- The study assigns losses to companies, estimating Saudi Aramco’s 1988–2015 oil emissions caused about $3 trillion by 2020 and could reach roughly $64 trillion by 2100 if left in the air.
- It quantifies personal choices, finding 2022 private jet flights by Bill Gates, Jeff Bezos, Elon Musk, Jay‑Z and Taylor Swift each exceed $1 million in damages by 2100, while a yearly long‑haul flight over a decade adds about $25,000.
- The authors present the framework as a scientific tool for loss‑and‑damage talks and climate lawsuits, say their GDP-based totals are conservative, and warn that a 25‑year delay in carbon removal leaves about half the damage done.
