The article is dedicated to the problem of decarbonising industrial gas emissions using adsorption methods. The article examines promising approaches to reducing carbon dioxide (CO₂) emissions using adsorption materials with high selectivity and efficiency in capture processes. The purpose of the study is to determine the adsorption capacity of various types of adsorbents, including synthetic and natural materials, in particular, fly ash synthesised by the hydrothermal method, zeolite obtained by the sintering method, natural zeolite, and fly ash from thermal power plants.

Following the European Green Deal, which aims to develop a closed-loop economy and reduce emissions of pollutants, Ukraine is also implementing it in its plans. Therefore, this paper analyzes and compares the reduction of CO2, NOx and SO2 emissions by the European Community countries and Ukraine. Actual data on achievements in reducing emissions of the specified substances and the plans of the countries under study have been analyzed and compared.

This article is devoted to the study of the carbon dioxide adsorption process. The relevance of using carbon nanotubes for adsorbing carbon dioxide from industrial emissions is that carbon nanotubes have a high surface area and can effectively interact with carbon dioxide molecules. In addition, they have high mechanical strength and chemical resistance, which makes them attractive for industrial use. Carbon nanotubes have the potential to reduce carbon dioxide emissions and reduce the negative impact on the environment.

Forest management involves the use of large areas of land and a large amount of related information. Therefore, the use of geographic information technologies (GIS) is substantiated for the processing, analysis, and visualization of information in forest ecosystems. Green plants and trees deposit carbon and retain it for a long time, they are the main absorbers of carbon on land, so to determine the carbon balance the study of wood growth, accumulation of phytomass in forest ecosystems is necessary.

Comparison of 10% CO2-N2 and 5% CH4-Ar gas mixture as a make-up of gas chromatography with electron capture detection (GC-ECD) for the measurement of sulfur hexafluoride (SF6) was investigated. It was found that 10% CO2-N2 shows the make-up characteristic comparable to 5% CH4-Ar. Thus, 10% CO2-N2 is considerable as an alternative to 5% CH4-Ar.
