Back in 2003, Dar-Lon Chang took a job as an engineer at ExxonMobil — a job he thought would be focused on transitioning beyond fossil fuels. But over a 16-year career, he found it harder and harder to reconcile the threat of climate change with Exxon’s role as an oil and gas producer. We talk to Dar-Lon about what it was like to work inside the oil giant, what finally compelled him to leave, and what his story means for millions of oil and gas workers as the transition to a low-carbon economy picks up steam.
