The article concentrates on the development of theoretical and methodological
foundations of statistical research in the field of national environmental and economic
accounting, which forms the basis for the development of indicators of climate change
under martial law and shapes the adaptation to these changes. Given Russia’s military
aggression against Ukraine, the national statistical system is faced with an urgent task
of ensuring the continuity of the production of complete and high quality statistical
information. The issue of forming a methodology for the production of statistical
information in the field of ecology, i.e. climate change statistics, remains unresolved.
Outlining ways to address this issue is an important condition for the improvement of
modern state statistics of Ukraine and the development of statistical theory and
practice, as this largely determines the quality of the information-related support for
environmental management at all levels. The statistical estimation of the dynamics and
structure of greenhouse gas emissions on the basis of the economic activity of
enterprises was performed. It was pointed out that among the various related branch
methods of obtaining information, the system of environmental and economic accounting is
the most relevant and source of high quality data. One of the aspects of solving the
complex problem of forming methodological bases for collecting statistical environmental
information is the creation of a national system of indicators of climate change and
preparing statistical informational products using administrative data sources. The
paper studies issues of producing ecological information relating to Ukraine according
to statistical data. Moreover, the main problems which arise during the construction of
national environmental accounts were characterised. Finally, the paper identified the
key factors which influence to the largest extent the quality of statistical data and
calculations, and which are necessary for the transformation and development of the
statistical estimation of climate change under Russian military aggression.
