The article is devoted to the study of theoretical and methodological aspects of strategic risk management of environmental risks of the transport enterprise. The urgency of the issue is due to the acceleration of changes in the external environment of economic activity of transport enterprises, which determines the need for adjustments to the management system. Strategic environmental risk management is currently the main direction for its effective management. Statistical data on the number of enterprises in the transport industry, the introduction of new fixed assets, the financial result of enterprises are given. The prerequisites for improving the risk management system of the transport enterprise, which is currently defined as one of the main tools for sustainable development of the enterprise. The need to take into account the trends of changing the prerequisites for risk management, which leads to the transformation of the system of strategic management of economic activity of the transport company to ensure the implementation of projects. The diagram of environmental risks in the context of the foresight approach of risk management of a transport company is presented. The definition of environmental risk is proposed to be carried out on three «horizons»: operational; tactical and strategic. It is proposed to determine the probability of environmental risk and losses from its occurrence using the formula for calculating the mathematical expectation from the PERT (Program Evaluation and Research Task) system. Management must understand the probabilities of risk and the results of its impact on the enterprise, its projects. This approach will provide: an understanding of the trend of risk change and, accordingly, will develop the necessary measures to respond to it; adjustment of risk management policy taking into account forecast risk values; identification of long-term prospects for environmental risk management. Forecasting environmental risk at the operational, tactical and strategic levels is a necessary element of the risk management system of the transport company.
