Episode Details

London’s facing a hidden crisis: three high ozone alerts this year, with most residents unaware of the danger. This toxic gas, formed by sunlight reacting with car and factory emissions, poses serious health risks—especially for those with respiratory or heart conditions. While Paris has responded with speed limits and vehicle bans during spikes, London’s Green Party leader is calling for clearer, more actionable alerts—maybe even a traffic light system. The Mayor admits hotter summers worsen the problem and is open to adopting smarter, user-friendly measures from abroad. The push is now shifting from warnings to real restrictions, aiming to protect Londoners’ health and restore trust in the air they breathe.
