The relevance of the study is determined by the growing negative impact of air pollution on public health and the environment. The aim of the study is a comprehensive assessment of the dynamics of air pollution in the countries of Western/Eastern Europe, East Asia and the impact of environmental investments and environmental protection strategies on improving air quality. The study employed a set of quantitative methods, including time series analysis, linear regression and correlation analysis, as well as scenario modelling of pollution trends. The study found that countries with an early start to environmental policies (Germany, South Korea) achieved the best results due to technological modernization, digitalization of control, and high investments. At the same time, Ukraine and Armenia demonstrate limited progress because of insufficient funding, fragmented measures, and the impact of external destabilizing factors. It is demonstrated that effective pollution reduction requires an integrated approach. It includes technical solutions, in particular, automated monitoring and the creation of eco-industrial parks. The importance of interregional and international cooperation, orientation on the best available technologies and the use of European standards is substantiated. The results of the study can be used to develop effective strategies for managing environmental safety in industrial regions.
