As a result of the work carried out, the main factors influencing on the formation of the technogenic load in the Arctic territories of the Krasnoyarsk Region were considered, taking into account natural and climatic features. On the basis of Bayesian networks, a methodology has been developed for assessing the probability of the occurrence of man-made hazards, followed by an assessment of the complex risk using the official statistics of the Russian Emergencies Ministry for the period 1996-2020. The obtained quantitative estimates made it possible to identify the main factors influencing on the formation of the man-made load in the Arctic territories.
