The transport strategy of the Russian Federation, taking into account the specific features of the country's transport system, requires the use of transport modeling when solving problems of carbon neutrality. The transport model solves multifaceted problems, including the forecast and assessment of greenhouse gas emissions. The main principles of developing transport models are considered. A comparison is made of the NIIAT and EEA/COPERT methods most often used in calculating greenhouse gas emissions using transport models. The main requirements for the results of calculations using a mathematical model of transport flows are formulated.

The intensification of technological processes in modern industries is accompanied by an increase in the volume of ventilation and technological emissions, which have an extremely adverse effect on the environment. As is known, wet dust and gas cleaning devices are widely and successfully used to solve this problem. However, the presence of a droplet dispersion of the working fluid in the purified air flow, which can pollute the atmosphere with components captured during the cleaning process, does not allow achieving the required degree of purification. The article presents designs of radial-inertial droplet eliminators, optimized for functional and energy characteristics, proposed for installation in intensive wet dust and gas purification devices for effective separation of droplet moisture.

The reliability of assessing the amount of accumulated waste in the context of an imperfect scientific and methodological base for standardizing MSW, in the absence of generally accepted calculation methods, is not high enough. The possibility of using cluster analysis in the formation of a statistical sample of objects of a stationary trade network in setting standards for the accumulation of municipal solid waste is shown. A methodology for the formation of a representative statistical sample of objects of a stationary trading network has been developed when setting standards for the accumulation of solid municipal waste based on cluster analysis.

The problem of developing an optimal waste management system is very relevant in many countries. To solve it, it is necessary to study the processes of waste accumulation, to systematize the factors and conditions that affect the generation of waste, to determine the features of establishing waste accumulation standards for various objects. The article discusses the features of the accumulation of municipal solid waste and the establishment of standards for their accumulation for stationary objects of the distribution network.The volume and mass values ​​of daily indicators of accumulation of MSW from a trading area of ​​a certain type and the total value of accumulation indicators (over the entire trading area) are found. The formats of retail facilities with the maximum average daily indicators of MSW accumulation have been established. Standards for the accumulation of MSW for the category under consideration have been established for 1m2 of retail space with food products, 1m2 of retail space with non-food products.

This article discusses various aspects of the design, construction and operation of shopping centers and shopping and entertainment complexes from the point of view of fire safety. Examples of existing structural and space-planning solutions that do not fall under the regulations governing fire safety, but pose a danger to visitors and staff of the shopping center and shopping mall in the event of a fire. Ways to eliminate these shortcomings are proposed.

The purpose of the full-scale investigations under the conditions of a pipe electric-welding production in operation was to obtain the necessary amount of actual data characterizing the features of the formation of aerosol emissions, their localization and treatment. During the investigation, the three main groups of factors were considered: the technological factors specifying the features of the technological process of pipe production, the technological conditions factors reflecting the power, frequency and composition of aerosol emissions, the operational aerodynamics of the ventilation systems for localization, removal and treatment of emissions.

In modern buildings constructed of mineral raw materials, the role of various components of natural sources of ionizing radiation, which form the radiation exposure levels of people, has changed significantly. The article considers the cost estimation of replacing construction materials with an enhanced effective specific activity (Aeff) with alternative materials with a lower Aeff. It has been revealed that the monetary equivalent taking into account the radiation safety depends mainly on the difference between the specific activity values of natural radionuclides (NRN) in construction materials and on the number of inhabitants. With a reduction in the difference between the Aeff values, the cost of the replacement (Ruble/t) of the materials decreases and the monetary equivalent grows.
