According to the Sustainable Development Goals (UN, 2015), making sustainable business decisions should be the driving force in achieving environmentally-oriented improvements. The key document that supports the 10 principles that ensure SDGs is the United Nations Global Compact Strategy 2021–2023 (UN, 2021). Achieving the goals of the Strategy requires the use of an improved business decision-making model that simultaneously increases revenues and revises the distribution of domestic funds for meeting the principles in the sphere of human rights, economic growth, satisfactory working conditions and the environment, and combating corruption as a key driver of corporate sustainability and responsible business practices. The authors have developed a methodological approach to the assessment of business sustainability, which is based on a combination of elements: analysis of world best practices and trends, determination of the impact of business on the social status and environment, quality assessment of relevant certification, and analysis of compliance with social indexes of sustainable development. The analysis of economic indicators of sustainable business (The B Impact Assessment, 2021) for 2020–2021 allowed singling out companies that finance the environmental sphere. Today, a quarter of the world’s countries carry on sustainable business and finance the environmental degradation impact. The 8 leaders include: France, USA, Brazil, India, Germany, Norway, Ireland and South Korea. Methods of rating and expert assessment constitute an applied aspect of research for identification of prospects of sustainable business formation in Ukraine in the regional context. The result shows that only 8 regions are suitable for sustainable business conduct, while the environmental criterion is more than 9.2 points of 10, the economic criterion does not exceed 5, and the social criterion is 4.02–5.02. Therefore, it is necessary to focus on the organization of sustainable business according to the key strategic state priorities in formation of the mechanisms for the investment and the innovation policy of a sustainable development support system through the use of regulatory tools for reformation of existing business approaches to internationally regulated ones, such as business for nature.

Littering is a daunting environmental issue that occurs daily; the impact of littering can range from lowering the aesthetic appeal of a city to polluting waterways and biomes. Littering persists on a collective and individual level despite the existence of numerous laws and regulations that prohibit it. We assume that there is a correlation between the effectiveness of visual aids and littering behavior. Poorly designed prohibitive signs and inaccessible trash bins could be part of the reason why littering persists. The current research aims to evaluate existing prohibitive signs and trash bins and to design some improvements. The researchers used direct observation methods of visual designs based on socio-psychological persuasion techniques and a questionnaire conducted at the School of Environmental Science of Universitas Indonesia. The results showed that respondents were generally aware of littering being a serious issue that could lead to environmental problems. The university campus was generally clean; however, respondents stated that they often saw plastic trash in sewer and drainage areas. University residents do litter despite adverse social judgment. In addition, respondents stated that they responded better to visually pleasing encouragement posters rather than the standard prohibitive signs on proper waste disposal behavior.

We live indoors. In the developed countries, people spent80-90% of time in buildings. Therefore, among the environmentalfactors, indoor air quality (IAQ) is a significant,if not the most significant, factor affecting human health.Scientific evidence has indicated that indoor air can bemore seriously polluted than the outdoor air in even thelargest and most industrialized cities. Indoor air pollutioncauses long- and short-term health problems and, dependingon the severity, can even make staying indoorsvery uncomfortable. Management of IAQ is a complicatedtask due to complexity of pollution sources and alimited number of measures applicable such as reducingcontaminants at the source, improving ventilation, and,when relevant, purifying the indoor air

Lessons learned from the crisis in Indonesia prove that the concept of community resilience, together with community-based development, significantly affects the ability to fight against the crisis at the local and community levels.  In addition to improving urban livability, today’s urban development in Indonesia must also struggle to overcome various pressures due to natural disasters. Community resilience is considered a bottom-up solution to address these problems. This study aims to see how community resilience affects settlements’ livability in Malang City, one of Indonesia’s medium-sized cities. This research also analyses the relationship between resilience and livability variables to formulate prescriptive development strategies. The research used quantitative analysis by compiling and selecting data from secondary and primary sources to formulate indicators  and variables of the proposed model. Descriptive analysis and structural equation modelling were conducted using SEM-PLS. The model built from this research shows that community resilience is the main factor that shapes livability in Malang City, indicated by social life, urban environment, and economy. Important variables forming community resilience are population vulnerability, physical infrastructure, and environmental infrastructure.

Rice issues are strategically important given that food sovereignty is one of the government’s strategic plans. The supply chain of rice is a complex system involving many interacting stakeholders. This study aims to analyse the rice supply chain in flood-prone areas, the level of rice business vulnerability to flooding, and the institutional competitiveness in the rice supply chain to improve food security. This study applied a mixed-method approach. The population of this research was business operators in the rice supply chain in the flood-prone areas of Klaten Regency, Indonesia. This study utilized primary data, which were collected using the method of direct interviews with business actors, supported by a list of questions and focus group discussions. The analytical tools used in this study were supply chain analysis, business vulnerability index, and stakeholder analysis. The results show that the rice supply chain consisted of farmers and rice fellers, collectors, rice mills, wholesalers, retailers and, finally, consumers. The vulnerability of companies in the rice supply chain was in the category of moderate. Stakeholders in the rice supply chain had diverse objectives, where the two most substantial goals were building reputation and earning income. Rice mill, Department of Agriculture, Food Security and Fisheries, and community are the main stakeholders in realizing food security because they have high interests and influence. The implication is that these three stakeholders must be the main actors in the development of regional food security.

The article aims to analyse livestock production factors and search for reserves to increase efficiency in achieving Sustainable Development Goals (SDGs). The main tasks of Ukraine in the framework of achieving the SDGs and the role of livestock in this process are identified. The world experience of sustainable livestock development has proved its contribution to overcoming world hunger. The main trends in livestock production development in agricultural enterprises of Ukraine are identified. The influence of livestock intensification on the economic and social efficiency of livestock production is determined. Ways to increase the efficiency of livestock production through innovation are substantiated. The system of factors of production efficiency is expanded, taking into account its social aspects; in particular, it is shown that the development of livestock has a significant impact on the internal social efficiency of enterprises, affecting labour demand and wages. The strengthening of specialization and concentration in livestock in Ukraine is following the same global trends. The influence of livestock intensification on the formation of the ratio "costs - production results" is proved, which made it possible to identify the possibility of increasing profitability while rising production costs per head of livestock. Increasing the production intensity can lead to increased technological, economic, and social efficiency.

The blooming of a deep open plan in office buildings is accelerated due to economic profit reasons. This hinders the utilisation of daylight despite having abundance of daylight in tropical climate. Although a light pipe (LP) provides a means to illuminate the deep interior of the space, non-uniform daylight distribution still occurs due to the high illumination contrast across the room. The integration of a shading device (SD) in a room with an LP offers a solution to create a uniform daylight distribution. In this study, daylighting performances of 5 different types of an SD with different angles were analysed through a computer simulation software, namely Integrated Environment Solution Virtual Environment. The simulation was done using overcast and intermediate sky with sun conditions. The results showed that all SD cases improved the daylight uniformity across the room. A horizontal Venetian blind with an angle of +45o and −45o showed the best qualitative performance among all the cases. However, further shading and illumination are needed respectively to increase the potential daylight utilisation in an open plan office room. This study also concluded that a vertical Venetian blind did not provide a good daylight uniformity due to the vertical nature of the SD. A design recommendation guide for building designers is proposed at the end of this study to promote the integration of an SD and an LP in deep open plan high-rise office building.

In recent decades, the growing number of citizens and improving life quality have increased energy consumption in the world and Europe, as well as in Lithuania. Despite the fact that an increasing number of countries are focusing on the development of renewable energy, most of the energy is produced by using fossil fuels. As a result, climate change is being felt more than ever before. One of the ways to mitigate climate change is the development of renewable energy sources in the world, Europe and Lithuania. Last year, Lithuania produced 5,142 TWh of electricity, which accounted for 47% of the country’s total electricity consumption, and 22.2% of all electricity consumption was generated using renewable energy sources. According to the Lithuanian National Energy Independence Strategy, 70% of electricity will have to be produced in Lithuania by 2030, reaching 100% by 2050. However, electricity imports and resulting energy dependence are still a major challenge in Lithuania. To address the ambitious goals of eliminating energy dependence and developing climate-neutral technologies, the last decade has seen the focus on the development of renewable energy, and wind energy in particular. Forecasts for the future suggest that by the middle of the century, the country will be producing electricity mainly from renewable sources including onshore and offshore wind energy, large- and small-scale solar energy, and bioenergy systems.

Airlines around the world are increasingly focusing on the environmentally sustainable management of wastes produced as a by-product of their operations. The objective of this work was to analyze Finnair’s non-hazardous waste (NHW) types and quantities, their NHW management strategies, and the methods used to mitigate the environmental impact of their NHW, over the period 2008 to 2019. To achieve these objectives, the study was underpinned by an in-depth mixed methods research design; this incorporated a quantitative longitudinal study and a qualitative document analysis. The results revealed that despite significant growth of their operations, Finnair’s annual NHWs have declined over the study period. Finnair’s annual NHWs decreased from 5,710 tonnes in 2008 to 4,212.01 tonnes in 2019. The primary waste disposal methods used by the airline are waste-to-energy recovery and waste recycling, both in-house and by external third-party service providers. Smaller quantities of wastes are composted. Since 2015, the company has had a policy of not disposing wastes to landfill.

The present study aims to assess groundwater potential in the Telidjene Basin located in the semi-arid part of eastern Algeria, applying an innovative approach combining both remote sensing and hydrogeophysics methods. A re-interpretation of geophysical data and vertical electrical sounding (VES) measurements were applied and calibrated with the borehole data to map the deep structures that may control the presence of groundwater and identify the geological and hydrogeological setting. Morphometric factors affecting recharge were mapped using several types of remote sensing data (SRTM DEM, Landsat-8). Thematic maps were overlaid using the multicriteria method and GIS to detect potential recharge areas. The results show that the main factors influencing recharge are fracturing and drainage density. Four potential recharge areas were identified over a 547 km2 area of the basin. 20% of the area falls in the weakest class, 32% in the weak class, 3% in the moderate, and 16% in the strongest. Furthermore, the study reveals that an alluvial aquifer with a thickness of up to 60m, spreading over the surface, along the Wadi Telijene and the alluvial soil, is deposited unconformably on Cretaceous terrain containing aquifer horizons of varying thickness and different electrical resistivities (10–150 Ωm), drawing an anticlinal structure with lithostratigraphy interrupted by a series of faults and spurs of Aptian and Triassic age. The south-western part of the basin has a high to moderate recharge and storage capacity. Its alluvial cover is directly fed by precipitation and fractured limestones deposited in a syncline outcropping on the edges forming an alluvial and carbonate bilayer aquifer. This study concluded that an integrated approach, involving recent, efficient, and inexpensive technology, such as remote sensing and conventional geophysical method, can be successfully used to identify groundwater potential in the study area.
