Presented results of research on digitalization and automation of geoinformation support for air quality management over natural-industrial territories under climate change. The methodology of natural risk management, as well as technologies for managing geographic information databases, were used while research. A model has been developed that allows combining investment goals for the development of natural-industrial territories with the costs of geoinformation support for air quality management over natural-industrial territories under climate change, including the problem of black carbon. A modular web-based tool has been developed to implement the proposed model. Examples of using the developed approach for St. Petersburg and the Leningrad region are given.
