Just saw the air quality maps for my city from 2019 versus now and the change is crazy
I was looking at some old data from the city's environmental reports, and the difference in the number of 'unhealthy air' days is huge. In 2019, we had over 40 days where the air quality was bad enough to get warnings. This year so far, we're down to maybe 15. The main reason seems to be the new rules they put in for the big shipping port, making ships use cleaner fuel and plug into shore power instead of idling. You can actually see the difference on the map around the port area, the red spots are way smaller now. It's not perfect, but it's a solid win that you can point to and say the rules worked. Has anyone else seen a real change in their local area from a specific policy like this?
