Air pollution in London has changed dramatically over the past few decades — but how much of that is down to policies like ULEZ, and what's still being missed? This week Helen Czerski is joined by Dr. Gary Fuller on the Everything Electric Podcast, an air pollution scientist at Imperial College London who has spent over 30 years measuring air quality in the capital. They cover what's actually in the air we breathe, how ULEZ and other low-emission schemes have changed it, and the surprisingly large health benefits that are now being measured — plus the pollution sources still flying under the radar.
