Proves ULEZ is the right call.
- 0x1ceb00da 1y agoCurrent AQI in london ULEZ is 48 according to google maps which is not that good. Does that mean AQI is not a very good measure of air quality?
- cinntaile 1y agoIt doesn't really make sense what you're saying. First you say it's not good but then you question the index. You're clearly using the AQI to base your opinion on? To answer the ULEZ question you should compare to not having ULEZ there, which is what the GP was talking about.
- 0x1ceb00da 1y agoRight so london aqi used to be much worse but ULEZ helped.
- CJefferson 1y agoI don't know the current average, but it used to often be much higher than that. Maybe the average has improved?
- daemonologist 1y ago48 is decent - at the high end of the "good" range - but AQI fluctuates a lot from day to day. There were some fires on the other side of the continent from me and that was enough to bump the AQI here above 80. Here's a report with some longer term trends (warning: 2MB PDF download): https://www.london.gov.uk/media/105046/download https://www.london.gov.uk/media/105046/download . Air pollution is down across London, and sharply so on the most proximate roadside sensors.
- echelon_musk 1y agoI wish all diesels could be included in the ULEZ ban. Or at minimum all non commercial diesel engines. As a motorbike rider I can taste the diesel fumes as soon as I'm behind one in a way that's unlike any petrol car. There's large particulates being thrown out by even the most luxurious diesel cars that you simply couldn't tell if you're behind in a car.
