The Clean Air Zone is being introduced later this year (currently they say 28 November 2022, but I think it's already been delayed twice.)
The scheme will see charges instituted for certain vehicles entering parts of the city, especially older diesel cars. This is to encourage people to change these older cars or find alternative routes or modes of transport. Apparently there are grants and loans available for upgrades on offer to private citizens and businesses.
This should only have positive effects for me, as I live just inside the zone, and I drive a recentish petrol car with an efficient and not-so-pollutey engine. In a perfect world, therefore, this scheme means my area might eventually start meeting the government's standards for air quality. This Bristol 24/7 article has some good info, including an estimate that there are currently 300 premature deaths per year from traffic-related air pollution in the proposed Bristol zone.
