The paper discusses a system of criteria that make it possible to assess the level of environmental safety of an enterprise. The model of the “nature-population-production” system and the very interaction of the system are presented. Environmental problems, problems of ecology of production, and consumption of natural resources lead to an increase in the rate of growth of production, which, in turn, leads to an increase in demand for resources, and as a consequence, to their irrational use, and then to massive emissions into the environment as waste. In order to improve the environmental situation in the country, some areas for improving the greening of the production sector are presented, which increase the efficiency of consumption and use of natural resources, while reducing environmental pollution by emissions, effluents, and waste. The main indicators that determine the level of environmental management are presented - indicators of resource intensity, an indicator of the degree of restoration of natural resources, and indicators of saving primary natural resources. All three indicators are part of the specific consumption of natural resources and can be used at the enterprise to control the consumption of natural resources, as well as in order to minimize waste through the use of secondary resources and low-waste technologies. The established ways of improving the greening of the production sector are able to improve the ecological situation in the regions of the country and establish the relationship between man, nature and the production sector.

The construction industry has a significant impact on our environment. When erecting buildings and structures, building materials, energy, water and other resources, the production of which violates the ecological balance, are used. The construction process itself has also negative effect on environment and the nearby objects with noise, vibration exposure, waste incineration, groundwater and soil pollution in general. However, the time period required for the construction of the building is insignificant compared to the period of operation. Experts estimate the service life of modern monolithic buildings at 125 - 150 years, and in some cases this index reaches 300 years. During this time, a new problem arises - the ecological balance violation: insufficient insolation, changes in natural wind flows, hydrogeology, vegetation reduction, soil and vegetation layer pollution, air masses stagnation, etc. All this creates the prerequisites for the creation of special environmental protection measures aimed at maintaining ecological balance. Thus, at each stage of the life cycle of a building, it is necessary to carry out the measures to protect the environment and minimize harmful effects on the environment. Today the prerequisites for the green building development are being laid in Russia. The main idea is to reduce energy intensity and increase energy efficiency in construction.

Advanced age is not a serious limitation in choice of laparoscopic access in both elective and emergency surgery in patients with colorectal cancer.
