The Climate TRACE tool clearly visualizes PM 2.5 dispersion plumes – fine particulate matter most harmful to human health. For Almaty, the website (
https://climatetrace.org/air-pollution/ghs-fua_2583 ) provides modeled scenarios for both prevailing and worst-case meteorological conditions, illustrating the potential scale of exposure across residential areas.
For many years, CHP-2 and CHP-3, which burn high-ash coal, have been cited among the main contributors to elevated PM 2.5 concentrations in the city. Due to wintertime solid-fuel burning and unfavorable weather conditions, Almaty topped the IQAir real-time online ranking of the world’s most polluted large cities during certain hours last season.
The Almaty Air Initiative supports converting the city’s CHP plants to gas, which is expected to reduce emissions by 12-fold at CHP-2 and by approximately 8–9-fold at CHP-3. Beyond fuel conversion, it is essential to build a systemic program for such facilities: deploy modern filters, install automated emissions monitoring, publish data and maintain open dialogue with energy companies, and assess population exposure through independent monitoring and local datasets.
To that end, together with the Nurlan Smagulov Foundation, the Almaty Air Initiative has installed 200 air-quality sensors across Almaty and the region – their data are already available in the MyCar app and will soon be published at dashboard.air.org.kz.
