Air quality management is carried out within the scope of the above-
mentioned international collaborations in compliance with the United Nations’
Sustainable Development Goals along with the 12th Development Plan (2024-
2028), Strategic Plan of The Ministry of Environment, Urbanisation and Climate
Change (2024-2028) as well as sectoral strategic plans and programs.

3. Modelling Applications Used in Air Quality Management

The Ministry of Environment, Urbanisation and Climate Change aims to
ensure the continuity of the emission inventory and reduce the uncertainty in
the calculations to the minimum possible level. In this regard, in addition to the
“top-down” approach, it is necessary to collect a higher level of activity data with
the “bottom-up” approach. For this purpose, “Air Emission Management – HEY
Portal” software based on geographical information systems has been developed.
The software can perform calculation, emission distribution, modelling and
scenario analysis for industrial, domestic heating and transportation emissions,
which are the main sources of air pollution (Gürtepe et al., 2014).
HEY Portal mainly consists of point sources, spatial resources, moving
resources, solid fuel, emission calculation, emission distribution, meteorology
and air quality modules, and there are many additional sub-modules such as
user management, map operations, reporting, admin panel.
Point sources module performs digitalisation of air emission measurement
reports of industrial facilities with environmental permits; there are, currently,
around 12.000 industrial facilities registered in the database which are shown
by sectors in Figure-2. Furthermore, it allows presenting various information
such as the contribution of industrial facilities to the percentage of total
emissions, cumulative assessment of emission levels and rankings by sectors/
provinces/countries.
