Using the Emissions Database for Global Atmospheric Research satellite data on the annual global carbon dioxide emissions, their distributions in the Donbass were obtained for the period from 2013 to 2018, indicating their main anthropogenic sources: large cities, thermal power plants and metallurgical plants. Control points were selected near and far from the largest sources of carbon dioxide emissions and, with the help of the resources of the Shared Use Center, systems for archiving, processing and analysis of satellite data of the Institute of Space Research of the Russian Academy of Sciences, the average annual vegetation indexes in the territory of Donbass and at control points for the same period of time were determined. A comparison was made of the reflection intensities in the near infrared and red regions of the spectrum, as well as the normalized relative vegetation indexes at these control points. It is indicated that there is no direct correlation between the values of vegetation indexes and the concentration of carbon dioxide in a given period of time. A sharp decrease in the volume of biomass was noted in a number of control points due to the appearance of signs of drought in the Black Sea region, as well as a significant increase in wild vegetation in the conflict zone in the eastern regions of Donbass.
