Adaptation to climate change should be based on reliable, scientifically and methodologically sound assessments of climate risks. At the same time, the selected risk assessment methodology can influence the process of risk identification and the choice of adaptation measures. This article presents a comparative assessment of existing regulatory methods for analyzing physical climate risks, including the national standard of the Russian Federation for assessing vulnerabilities, impacts, and risks in the field of climate change; methodological recommendations of the Ministry of Economic Development for assessing climate risks; and recommendations of the Task Force on Climate-Related Financial Disclosures. The methodological differences influencing the results of the climate risk assessment are identified; it is noted that the key influence on the differences is exerted by the vulnerability assessment of the risk object due to different approaches to determining threshold values. Using the example of two oil and gas facilities, it is shown how the choice of methodology affects the determination of significant climate risks and associated consequences. The key advantages and disadvantages of the methods are highlighted; the use of an approach combining the advantages of all three methodologies is proposed, which will allow the most flexible formation of various options for climate risk management strategies, including adaptation measures.
