London Is Now the World’s Largest Low-Emissions Zone. Was the Fight Worth It?

Every driver in London, as of Tuesday, is now subject to strict pollution rules, completing one of the world’s most ambitious vehicle emissions policies and taking the British capital closer to having healthy air.

While the final expansion of the ULEZ, or ultra low emissions zone, is only a continuation of clean air charges that have been tightening since 2008 — under Boris Johnson when he was mayor of London and now his successor Sadiq Khan — this last phase has been the most controversial. That’s because the £12.50 ($15.72) per day levy for most non-compliant vehicles now hits those living in outer boroughs of London, where people tend to be more car dependent and have lower incomes.
