The rapid growth of online food delivery in urban areas reflects changing consumer lifestyles, but it has also contributed to increasing plastic waste and challenges in waste management. This study investigated the composition of municipal solid waste (MSW) related to online food delivery, consumer ordering behavior, and single-use plastic (SUP) generation in households in the Bangkok Metropolitan Area. Data were collected from 385 food delivery customers via online questionnaires. The results show that the proportion of plastic waste in MSW has increased, with 76.6% of participants reporting higher online food delivery usage. SUPs from food delivery, including non-essential items such as plastic films, spoons, and cutlery, were prevalent, and participants rarely selected green options to opt out of receiving them. These findings highlight the need for targeted interventions, including closed-loop management involving producers, platforms, consumers, and government. Policy recommendations include implementing extended producer responsibility (EPR) for environmentally friendly packaging, providing incentives for merchants and consumers to reduce SUP, applying the polluter-pays principle (PPP) to users, and designing government policies to regulate SUP and improve plastic waste management.

The valorisation of household and commercial bio-waste into soil improvers helps to reduce disposable waste, mitigate climate change, and improve soil resilience. While the separate collection of bio-waste is mandatory in the European Union, this remains a challenging task, particularly for large cities, due to quality problems in densely populated areas. In addition to various informational and motivational tools for households, financial incentives are becoming increasingly important. However, there is a lack of robust evidence regarding the optimal use of these incentives and their impact on the quantity and quality of collected bio-waste. We investigated the impact of different charging systems on the quantity and quality of bio-waste, basing our research on the experiences of more than twenty European cities and using a detailed questionnaire completed by the relevant administrators. The results confirm that cities, which provide financial incentives for waste sorting, yield a higher quantity of separated bio-waste. As introducing tiered fees can lead to quality issues, monitoring bio-waste and taking action against polluters seems to be unavoidable. Since the identification of polluters is very difficult in the case of multi-family homes, the results are discussed with a special focus on densely populated cities. Pilot projects for alternative options for the valorisation of organic waste, particularly in districts with high-rise buildings, should be evaluated. Full article

Life cycle assessment (LCA) is an excellent tool for developing energy saving and emission reduction strategies. However, inconsistencies in the summary calculation methods in LCA can significantly affect the reliability of LCA reports, such as the allocation of environmental loads related to solid waste. Essentially, allocation methods are used to allocate responsibility for environmental loads in situations where boundaries are unclear, and therefore, they are susceptible to regional, industry, and regulatory influences. For a long time, there has been controversy over the selection of allocation methods. This study is based on actual production data from a typical cement plant in South China. Multiple parallel LCA cases were carried out using different allocation methods, and different allocation methods were analyzed. Concepts such as driving force, active/passive environmental load, Valorized Solid Waste (VSW), and Non-Valorized Solid Waste (NVSW) were introduced. Analysis shows that the choice of allocation method directly affects the effectiveness of energy saving and emission reduction plans in the LCA report. For VSW, the economic allocation method has been proven to have high universality, effectively capturing the driving forces of economic factors. For NVSW, based on the “polluter pays principle” and active/passive environmental load, we introduced the Collaborative Disposal Allocation Method (CD method). In this study, the environmental benefits of domestic waste collaborative disposal were calculated using the CD method, resulting in a 2.25% reduction in global warming potential (GWP) and a 45.39% reduction in respiratory inorganics (RIs).

The United Kingdom has had a series of unsuccessful attempts at securing land value capture in 1909, 1947, 1967, and 1975. The 1909 land duties would have taxed increases in land values irrespective of the source. The latter three combined public bodies, acquiring development land with levies on developers. For them, value uplift was limited to that arising from the granting of planning consent. None of the measures were fully implemented and were reversed by incoming governments. One of the key problems with value capture policies has been the lack of political consensus. Since 1979, consensus has developed around the use of three types of value capture instruments. Development corporations have been created for the regeneration of local areas by acquiring development land and improving it. Local authorities have been able to use planning obligations and community infrastructure levies to oblige developers to mitigate externalities. Governments have made it clear that these are not to be used as value capture devices and therefore are really applications of the polluter pays principle. Thirdly, there are national taxes that fall on increases in the value of land, namely, business rates, stamp duty land tax, capital gains tax, and inheritance tax. Full article

This study examined Korean anglers’ willingness to pay (WTP) for the establishment of a Recreational Fishing Environment Fund (RFEF), aimed at mitigating the environmental impacts of recreational fishing on marine resources. As recreational fishing has expanded in Korea, concerns have grown over its negative effects on fishery resources and coastal pollution. Addressing these issues requires sustainable policy interventions, with financial support from stakeholders. To estimate anglers’ WTP for such a fund, a vignette survey was conducted in February 2024 among 1000 South Korean adults with experience or interest in recreational fishing. Using the Double-Bounded Dichotomous Choice Contingent Valuation Method (CVM), the present study estimated an average annual WTP of USD 8.18 per person. These findings provide essential data for designing coastal and ocean environmental policies based on the beneficiary pays principle, offering a financial framework to support conservation efforts and regulatory measures. The results highlight the potential for angler-funded environmental initiatives and can inform policymakers on the feasibility of implementing a dedicated fund for sustainable recreational fishing management.

Greek wines excel in quality and exports, but the viticultural sector faces significant challenges from complex supply chains, shifting European policies, and the growing need for sustainability amidst climate change and economic pressures. External environmental costs could affect significantly the decision-making process of farmers, reflecting a broader evaluation of sustainability in viticulture. This study evaluates the economic and environmental impacts of organic, integrated, and conventional viticulture management systems in Drama, Greece using a life cycle (LC) approach and data envelopment analysis (DEA) to determine efficiency, quantify environmental impacts in monetary terms, and incorporate these costs into the analysis. Organic management systems have lower energy consumption and emissions compared to integrated and conventional systems, with organic systems ranging from 4546 to 6573 kWh/ha in energy use and 1358 to 1795 kg CO₂ eq./ha in emissions, while integrated and conventional systems range from 9157 to 12,109 kWh/ha and 2961 to 3661 kg CO₂ eq./ha. The DEA analysis reveals that most organic systems perform efficiently when accounting for environmental costs, whereas conventional systems face significant efficiency declines, with only a few maintaining optimal performance. Policy-supported transitions based on the provider gets principle are crucial for balancing economic and environmental goals in viticulture, as the integration of shadow prices significantly impacts efficiency.

Recently, with climate deterioration and environmental pollution, consumers are becoming more and more aware of the use of sustainable energy. In particular, the demand for electric vehicles that use sustainable energy is also increasing. In addition, due to the simple driving principle of pure electric vehicles, many electric vehicles developed by electronics companies are continuously being launched. Electric vehicles not only use renewable energy to protect the environment but also save on various usage expenses, so they are expected to become the main products in the mobile travel equipment market in the future. This study aims to explore the impact of product design dimensions on electric vehicle (EV) purchase intentions, provide a theoretical basis for companies’ differentiation strategies, and reflect the impact of product design on purchase intention. This study uses Davis’s TAM combined with environmental awareness (EA) for analysis; an online survey was conducted on Chinese (n = 468) and Korean (n = 409) consumers, both male and female, aged 20–60 years and above. We found that, for Chinese consumers, the aesthetic and symbolic dimensions do not affect perceived usefulness and perceived ease of use, but they do affect environmental awareness, while the functional dimension affects not only perceived ease of use and usefulness but also environmental awareness. For Korean consumers, the aesthetic, functional, and symbolic dimensions all affect perceived ease of use and environmental awareness, but perceived usefulness is only affected by aesthetics and environmental awareness. Through simulation analysis, the results show that perceived ease of use, usefulness, and environmental awareness all directly affect purchase intentions. Perceived ease of use and environmental awareness are particularly important for Chinese consumers, while Korean consumers pay more attention to the test drive experience and environmental awareness. The results show that electric vehicle manufacturers should develop new technologies for the Chinese market to attract consumers, while in the Korean market, they should improve perceived usefulness through test drives and pay attention to environmental awareness. Specific statistical data show that both Chinese and Korean consumers assign importance to the impact of environmental awareness on purchase intention, proving the importance of environmental awareness. The results of this study will be of great reference value to electric vehicle manufacturers, policymakers, and consumer behavior researchers, helping them to better understand the role of product design in improving the market acceptance of electric vehicles.

A lightscape, as a special visual landscape, has unique temporal and spatial characteristics that traditional photometric measurements and descriptions struggle to capture accurately. Despite their significance, there is a lack of in-depth understanding of the on-site perception of lightscapes’ temporal and spatial characteristics, including in outdoor university campus spaces. This study aims to explore the temporal and spatial characteristics of outdoor lightscapes on university campuses and their potential perceptual influencing factors, providing sustainable design, planning, and management suggestions for campus lightscapes. This study was conducted in the Wushan Campus of the South China University of Technology. It employs a “lightwalk” method for on-site perception evaluation, combining qualitative and quantitative approaches to investigate the temporal and spatial characteristics of lightscapes in outdoor university campus spaces and the effect of temporal and spatial factors on lightscape perception. The main findings are as follows: (1) Meteorological, architectural, and biophilic lightscape dominate the outdoor campus lightscapes. (2) The temporal and spatial characteristics of the lightscapes are affected by changes in natural light, the transition of light sources from day to night, human activity patterns, and the functional characteristics of the site. (3) The correlation between meteorological and traffic lightscape types and lightscape perception is diminished during the evening periods. This method should be a good way to optimize water and architectural lightscape at night to alleviate discomfort. (4) In green-shaded spaces, the association between meteorological, architectural, and traffic lightscape types and the evaluations of emotional, luminous, and eventful aspects is significantly enhanced, suggesting an increase in such spaces to improve lightscape experience quality. This study advocates that the construction of buildings and environments should be “human-oriented”, paying attention to the scientific foundation that humans perceive the habitat environment through the “five senses”. Research on lightscapes’ temporal and spatial characteristics, exploration of the temporal and spatial modes of lightscape perception, and avoiding energy waste and light pollution are conducive to the design and construction of university campuses in line with the principles of sustainable development. The lightscape optimization strategies derived from this study can not only provide practical guidance for the design and management of campus but also may offer valuable recommendations for planning sustainable campus development.

China’s sewage treatment standards have been gradually improving, yet there is a widening gap between sewage treatment fees and actual costs. This discrepancy, where the fees for sewage treatment are lower than the actual operational expenses, poses a significant bottleneck to the sustainable development of China’s sewage treatment industry. As a core aspect of environmental economic policies, sewage treatment fees are pivotal in regulating water pollution emissions and addressing water resource shortages. Currently, there are major issues with sewage treatment fees, including an incomplete pricing system, insufficient fees, unclear fee distribution, and a heavy reliance on local finances. These problems impede systematic planning, diminish management efficiency, and hinder the sustainable development of the sewage treatment industry. Thus, future research efforts should prioritize the establishment of a pricing mechanism that comprehensively covers the full cost of sewage treatment. This article presents a concise summary and review of the current situation, types of fee collection, cost accounting methodologies, challenges, and proposed countermeasures for sewage treatment fees, and could serve as a relevant reference for future research on sewage treatment fees. By comprehensively addressing these issues, the sewage treatment industry would progress towards healthier and more sustainable development, ultimately achieving the goal of green growth.

Research on the Ecosystem Conservation Charge Return Project (ECCRP), a restoration initiative guided by the polluter-pays principle, is limited. Moreover, certain projects lack location analyses and specific restoration goals. Here, we examined the ecological restoration trends in South Korea based on the ECCRP. We collected data from 277 projects completed between 2003 and 2022 and explored project characteristics, site types, locations, and restoration target species trends. Wetlands and urban areas were frequently targeted, with forestry as the primary land category. Such projects prioritize restoration in areas with a potential for increased biodiversity. Small-scale projects were the most common, likely because of budget constraints and site selection challenges. The establishment of guidelines in 2010 resulted in considerable changes in restoration projects. Forested areas and parks close to species supply sources became important, and specifying target species for restoration was emphasized. Target species primarily included birds, amphibians, and insects. From a sustainability perspective, it is crucial to consider post-monitoring. Species of high restoration value and animals with a small habitat must be selected as performance indicators of restoration outcomes. Our results can help the ECCRP to strengthen the ecological restoration approaches to better achieve sustainability goals—improving biodiversity and conserving and restoring ecosystems. Full article

Current and future challenges such as the climate crisis, demographic change and achieving the objectives of the Water Framework Directive require holistic and precautionary approaches within the framework of national and supranational strategies. Specific measures and projects resulting from these strategic activities are required to successfully meet the challenges. In 2016, the German Environment Agency (UBA) and the Federal Ministry for the Environment (BMUV) commissioned the process for the development of the Federal Government’s micropollutants strategy, which was later named the Trace Substance Strategy. The essential core instrument herein was a multi-stakeholder dialogue aimed at giving sufficient consideration to the different interests of the various stakeholders. The goal was to develop a balanced mix of measures and to initiate implementations in order to reduce emissions of micropollutants as effectively and efficiently as possible, at the source, in their application and in the downstream areas. The various measures were tested in a pilot phase, and the activities were evaluated before being transferred into the subsequent consolidation phase. This article describes the outcomes of the stakeholder dialogue as an instrument. This is complemented by the results of a stakeholder evaluation of the process itself and the results achieved. Important outcomes of the stakeholder dialogue are a Committee for the Identification of Relevant Micropollutants and the use of roundtables as an important instrument in which the manufacturers and the users of the substances can make an important contribution to reducing emissions. To address the opportunities and necessities of additional wastewater treatment, an “orientation framework” for municipal wastewater treatment plants was also established. Additionally, the German Centre for Micropollutants (SZB) was founded to continuously organize, support and accompany the various outcomes that became relevant pillars of the German government’s Trace Substance Strategy. The evaluation has shown that new approaches and new instruments have been created within the framework of the stakeholder dialogue, which enable flexible and short-term options for action and allow for the involvement of stakeholders in a manner appropriate to the polluter-pays principle. Specific emission reductions could not be expected within the time frame of the dialogue. However, stakeholders agreed that the strategic process chosen is preferable to purely regulatory steps due to the holistic approach involving all stakeholders concerned in this complex matter. It is expected that in the future, if implemented consistently, the approach could achieve a lasting and sustainable impact on a broad scale. Full article

The textile and fashion industry is the second industry (after aviation) that pollutes the planet the most, and it uses natural and human resources excessively and irresponsibly. Fast fashion harms the environment. Fast fashion stands for low quality, low prices, constantly updated supplies, and high consumption of natural resources and chemicals. Nowadays, however, the evolution in the fashion industry from fast and unsustainable models to sustainability and a circular economy is firmly established. Fashion industry representatives are paying more and more attention to corporate social responsibility, business ethics, the implementation of circular economy principles, and the technological transition from linear production to a circular economy. The aim of this article is to evaluate the attitude of young Lithuanian designers towards the implementation of circular economy principles in the fashion industry. A problematic question is raised: how do young Lithuanian designers perceive sustainable fashion in the context of a circular economy? A qualitative semi-structured interview was used to collect data for the empirical study. The analysis has shown that the transition of the textile and fashion industry to a circular economy is a rather complex process that requires knowledge, significant financial investment in technological change, and greater consumer purchasing power in the production of products based on a circular economy. Moreover, new brands in the fashion industry do not always have enough information to start a business in the fashion industry based on a circular economy. A qualitative study conducted in Lithuania using the interview method showed that young Lithuanian fashion designers are very positive about sustainability solutions in the fashion industry and try to link their developing fashion brand with sustainability, but this is done fragmentarily rather than consistently. Young fashion designers state that they lack the in-depth knowledge and money to develop a brand in a circular economy. In conclusion, young Lithuanian fashion designers strive to create a sustainable fashion brand and link their development activities to a circular economy in a fragmentary way. Even after the research has been conducted, the question of how to get fast fashion manufacturers to produce sustainable fashion in Lithuania remains open. Full article

Municipal solid waste charging schemes can be powerful drivers for local policy efforts in reaching the goals of the 2030 Agenda for Sustainable Development adopted by all United Nations Member States in 2015. This paper aims to provide empirical evidence on an economic lever to meet SDG 11, Target 11.6 and SDG 12, Target 12.5 by applying the polluter-pays principle to waste management that also depends on user engagement through modern incentivizing charging systems. Unit pricing schemes in municipal solid waste management are often associated with a higher percentage of separated waste, less per capita waste production, and reduced service costs. We checked whether unit pricing schemes and the percentage of the sorted waste collection were correlated, assessed whether there is an impact on per capita waste generation, examined the impact on the total cost of management, and explored how specific phases of waste management were affected. The analysis was based on an empirical sample of 1,636 municipalities, of which 506 had unit pricing schemes in place. Our results confirm that unit pricing schemes can be associated with a higher percentage of sorted waste collection and less per capita waste generation. The impact of unit pricing on the total cost of management was not found to be significant, probably due to different impacts on specific services and phases of waste management. The policy implications are as follows: it is suggested that public administrators put data-driven policy targets into government programs that are applied at an operational level by competent municipal civil servants and codified into single programming documents for contracting waste management utilities according to SDG 11 Target 11.6 and SDG 12 Target 12.5.

In the water sector, the problem of pollution-source identification was mainly investigated regarding pressurized distribution networks, with respect to sewers. Even if the Water Framework Directive 2000/60/EC and equivalent law-making bodies in many countries introduce the principle that the polluter pays, it is asking the water manager to detect the most pollutant discharges in sewers. In previous studies, a probabilistic approach to positioning water quality sensors in urban drainage networks shows the progressive increase in identification probability obtained through the Bayesian approach. Following previous literature, the present work aims to improve it by inserting new information beyond network topology. The methodology is applied to the real test case represented by the sub-catchment of the sewer system Palermo (Italy). Full article

A change in human development patterns is needed, including mankind’s environmental, economic, and social behavior. Engineering methods and practices have a substantial impact on the way to sustainable development. An overview of the guiding principles of sustainability, sustainable design, green engineering, and sustainable engineering is presented first. Sustainable engineering principles need to be updated to include the present state of the art in human knowledge. Therefore, the updated principles of sustainable development are presented, including traditional and more recent items: a holistic approach, sustainability hierarchies, sustainable consumption, resource scarcity, equalities within and between generations, all stakeholders’ engagement, and internalizing externalities. Environmental, social, and economic impacts that respect humans’ true needs and well-being are of importance to the future. The updated 12 principles include the tridimensional system’s approach, precautionary and preventive approaches, and corporate reporting liability. The environmental principles comprise a circular economy with waste minimization, efficient use of resources, increased share of renewables, and sustainable production. The social pillar includes different views of equality, the engagement of stakeholders, social responsibilities, and decent work. Economic principles embrace human capital, creativity, and innovation in the development of products, processes and services, cost-benefit analysis using the Life Cycle Assessment, and the polluters must pay principle. The principles will require further development by engaging individual engineers, educators, and their associations. Full article
