Criteria for evaluating environmental performance are analyzed along with mechanisms for selecting environmental indicators. It is proposed to use the intensity of greenhouse gas emissions as a criterion for determining the ratio between the volume of greenhouse gas emissions and a company’s activities. The evaluation of environmental performance enables an assessment of environmental risks, the development of approaches for reducing the human impact on the environment, as well as the design of long-term production development plans taking into account possible changes in the state of the environment in oil refining regions.
