      this is normal, fast winds and rain few weeks back washed away all the dust, pollution and whatnot. now it has not rained in a while, there is no wind, the weather is overcast and the emitted pollutants are stuck over the city

      during covid when driving cars was prohibited tbilisi air felt like skiing resort. i thought switching to evs would do that but the global view on that matter changed. after china started making majority of them west kinda pulled out of that game so i dont’t think we are switching to evs anymore. imagine Tbilisi without engine noise and smog clouds… would be cool.

      It’s not only cars, there are also gazilion constructions all over the place

      I think that regular cars will make up maximum of 15-20% of pollution (even that seems bit stretched).

      I see 1 major contributor and its 3 main problems.

      1. 20+ story building constructions in every 100m
      2. Construction equipment that roams the city streets more often and in larger quantities than public transport
      3. Streets are never cleaned from dust and debris

      AQI is really high right now. It’s cars (with the actual problem not cars themselves but traffic jams, which can be reduced through policy) but also coal burning and other industry (in Rustavi area in particular) as well as fine dust coming in on windy days from the desert. Completely possible to reduce substantially but that would require a government focused on citizens‘ needs instead of trolling people and collecting cheques.

      Hey dear neighbours. Im from Azerbaijan and doing research on weather quality for about 2 years. Shortly, results showed that this unhealthy weather mainly comes from Iğdır city and around regions in Turkiye during winters. Because people don’t use gas there for heating.

      I think Azerbaijan may solve this problem by supplying free or much affordable gas to Iğdır city….

      My understanding is that the worst pollution in the city comes from PM2.5 (particles under 2.5 micrometers in diameter). These are released especially from older vehicles. You can monitor the air quality online. Some people buy these air quality monitors (basically scientific instruments which measure the concentration of different pollutants in the air) and link them to online portals so everyone can see.

      Typical winter inversion layer which traps emissions at a low altitude between the ridges surrounding Mtkvari valley

      We ripped out our tram system while each family has like 5 cars each – I’m surprised the air isn’t even worse than it is now.

      Cars are a HUGE root of Tbilisi’s air quality problem. Investing in public transport, specifically expanding the metro, is the only way forward while policies like congestion pricing (such as in London/NYC) can bring about much more substantial and immediate change.

      Every time I arrive to Georgia from a foreign country, I get unwell because of the pollution and start having breathing problems.

      Yes, that’s that bad for me at least.

      In my observation it’s about wind direction. Prevailing winds alternate between northwest and southeast. Whenever wind blows from the northwest, even gently, the air is cleaner. When it blows from the southeast, the valley fills up with thick pollution. At first I thought this was particular to a neighborhood and how much traffic is upwind, but later I realized it affects the entire city.

      Maybe something about topography comes into play? Maybe air gets trapped in the valley more when it’s coming from southeast. Or maybe there’s some heavy industry that way. But I think the main sources of pollution come from traffic and construction within the city.
