The paper examines the architecture and functional features of digital energy consumption monitoring systems and their role in the decarbonization of industrial production. The strategic importance of digitalization for building sustainable business models, improving resource efficiency, and meeting climate commitments is emphasized. The possibility of integrating digital monitoring systems with corporate management platforms (ERP, MES) is noted, which enhances the completeness of energy consumption data, ensures its comparability across production sites, and contributes to the preparation of more accurate non-financial reporting. Particular attention is paid to the relationship between monitoring energy flows, managerial decision-making, and reducing the energy intensity of industrial processes. The practical component is presented as a parametric scenario analysis that enables a quantitative assessment of reductions in CO₂ emissions (Scope 1 and Scope 2) under different levels of energy consumption optimization. The results demonstrate the significance of digital monitoring as a tool for decarbonization, preliminary assessment of environmental effects, and improvement of the resource efficiency of production.

The aim of the study is to justify the feasibility of using household electrostatic precipitators (ESPs) to reduce particulate emissions from individual heat sources (IHS) in Siberian cities, using Ulan-Ude as a case study. The object of the study is particulate emissions from private coal- and wood-fired boilers and furnaces. Methodology includes field measurements of flue gas dust content (aspiration method, thermoanemometry), Deutsch formula calculations, laboratory ESP modelling with fly ash, and particle size distribution analysis. Average IHS flue gas dust concentration is 1.0 ± 0.2 g/m³ at a flow rate of 260 ± 70 m³/h; equipping 50% of coal-fired boilers with ESPs (99% efficiency) would reduce particulate emissions by 3000-4000 t/year. The developed two-zone ESP with power consumption of ~315 W and dimensions of 1.4×0.45×0.7 m can be integrated into the chimney of a private house instead of a standard section.

The relevance of the work is determined by the need to ensure environmental safety during coal transshipment at the non-specialized terminal of JSC Vanino Port. The level of atmospheric air pollution with coal dust in the residential area of the settlement and above the water area of Vanina Bay was determined based on modeling the dispersion of emissions in the atmosphere in the program of the Environmental Protection Agency “Ecologist-4.6.ˮ 91 sources of coal dust emissions were taken into account. 10 options for the organization of work have been considered. Dispersion calculations have shown that the air protection measures carried out by Port Vanino JSC are not effective enough. Dispersion calculations have shown that the air protection measures carried out by JSC Port Vanino are insufficiently effective. According to the most unfavorable variant of the organization of work, the ground concentrations over the bay water area will be from 0.579 to 2.37 mg/m3, in residential areas - from 0.049 to 0.115 mg/m3 (from 0.16 to 0.38 shares of the MPC), the maximum contribution is given by dusting of warehouses. The use of a 20-meter-high screen around the entire perimeter of the warehouses makes it possible to reduce surface concentrations by 10 times, ensure compliance with regulatory requirements, and reduce dust deposition in the bay area. The potential risk of developing non-specific toxic effects in chronic intoxication at control points in residential buildings is reduced from the category of “dangerousˮ to “acceptableˮ, which confirms the effectiveness of the proposed measure.

The research is devoted to a comprehensive study of the state of green plantations in the town of Tarusa, the Kaluga Region, aimed at assessing the ecological condition of the landscapes and developing recommendations for their sustainable development. The work involved an inventory of flora, an assessment of the state of trees, shrubs, lawns, and flower beds in various functional zones (transport, residential, public, industrial), and the NDVI method was applied to analyze the dynamics of vegetation cover. The results of the study revealed significant degradation of green spaces: 36% of trees and 55% of lawns are in an unsatisfactory condition, and 59% of plant species are found fragmentarily. Based on the data obtained, measures for the optimization of urban landscaping are proposed, including sanitary pruning, planting of resistant species, and control of invasive plants. The practical significance of the work lies in the possibility of using the results for urban planning and environmental monitoring not only in Tarusa but also in other small historical towns.

Against the backdrop of increasing anthropogenic pressure exerted by the Moscow Region (hereinafter-MR) on adjacent territories, the development of environmental tourism is becoming an imperative to preserve regional biodiversity. The established practice of using ecological trails as leisure rather than educational facilities conflicts with sustainable development. This creates risks of ecosystem degradation and misses opportunities for public environmental awareness. The aim of the study is to identify systemic barriers that hinder the effective functioning of environmental trails and to develop recommendations for integrating these facilities into the regional system of lifelong environmental education. Based on an analysis of empirical data on key regional sites, the author has carried out a typologization of existing routes and revealed structural problems - from pronounced seasonality to a “methodological vacuum.” The study’s novelty consists in providing a basis for the transition from an extensive development path (increasing the trail length) to an intensive one (enriching routes with educational content). An original solution matrix is proposed, represented by the implementation of Citizen Science approaches and digital technologies (EdTech), enabling the transformation of visitors from passive observers into active investigators. The recommendations formulated in the article can be used by relevant ministries and educational institutions to modernize the MR’s tourist infrastructure and to create innovative educational products.

Petroleum products affect the chemical and microbiological properties of peatmarsh top soils: sulfate ions concentration increases by 80.99-91.01%, sodium salt concentration changes from 141 to 3151 mg/kg, species diversity decreases, and moldy fungi appear. The object of research is peat-marsh top soils with different concentrations of oil pollution. Methods for studying the properties of oil-contaminated peat-marsh top soils, sorption materials, and oil biodegraders for creating a sustainable phytocenosis include gravimetric methods, capillary electrophoresis, inductively coupled plasma spectrometry, soil suspension seeding on selective media, etc. When adding mineral sorbent glauconite and microorganisms strains, the biological and physicochemical properties of peat-marsh top soils are altered: the concentration of petroleum products is reduced by 81-92%, the concentration of sodium salts is reduced by 95.9-97.9%, and the pH of the soil changes. After applying a combined method with the addition of mineral sorbent glauconite and microbial strains, peat-marsh top soils are approaching the original state of uncontaminated peat-marsh top soils in terms of their physical and chemical properties, making them suitable for creating a sustainable phytocenosis.

This study presents the results of hydrochemical monitoring of the chemical composition of atmospheric precipitation and soil water in the Valdai Upland. The influence of tree crowns and water-temperature conditions on the composition of precipitation as well as the impact of elementary landscape types on the composition of soil has been investigated. It was found that interaction with spruce tree crowns changes the calcium-bicarbonate composition of free precipitation to potassium-bicarbonate. The main input of Ca, Mg, Na, and K into undercrown water occurs due to dust washout from tree crowns. It was revealed that the pH of soil water increases with increasing depth of soil water formation and is independent of the type of elementary landscape. The concentration of macrocations decreases in soil water of the transeluvial type of elementary landscape. With increasing depth of soil water, the leaching of K, Na, Zn, Si, and SO4 is activated, which is associated with changes in the particle size distribution of soil horizons.

The study aims to develop a criteria framework for assessing the effectiveness of integrated environmental monitoring systems that combine distributed sensor neworks (DSN) and Internet of Things (IoT) technologies for water and air quality control. The object of research is the architecture of integrated systems merging stationary and mobile measurement nodes. The methodology employs systemic and multi-criteria analysis across four groups: technological (network density, sensor stability), informational (spatial representativeness, suitability for digital twins), economic (total cost of ownership, prevented damage), and regulatory. A review of international experience revealed a gap between IoT sensor capabilities and regulatory requirements. A three-level architecture is proposed - from field data collection to a cloud platform of digital twins that generates heat maps normalized to permissible exposure limits. The main conclusion: key barriers are primarily normative and methodological rather than technological. A dense network of low-cost sensors has been shown to cut the “blind time” of leak detection nearly in half, confirming the value of synergistic effect over episodic measurements. The proposed criteria system provides a methodological basis for substantiating and auditing digital monitoring projects, facilitating the transition to a predictive environmental risk management model.
