The current studies on carbon dioxide (CO2) emissions and the impacts on public health focus mainly on evaluating CO2 emissions from two types of emission sources. The first is a fixed source type from industrial plants, which can be controlled or easily evaluated. The second is a mobile source type from the transport sector, especially from medium- and heavy-duty vehicles (MHDVs), which produce high emissions. However, the common methods of evaluation of the average value of CO2 emissions per kilometer of a vehicle use a general Intergovernmental Panel on Climate Change (IPCC) model that does not consider the topography or road conditions. This affects the accuracy of CO2 emission assessments and, in turn, affects the accuracy of any analysis needed to establish health policies and the management of public health within the affected area. In this paper, therefore, we present the development of emission coefficient calculations with varying topography conditions for MHDVs with consideration of the health effects on the populace. The study area was the Asian highway network in Thailand that passes through all regions and is geographically diverse. Data were collected from the Department of Highway’s records, global positioning system (GPS) and electronic control unit (ECU) with data consisting of road data, slope, distance, traffic level and vehicle weight, as well as fuel consumption along the transportation route. To analyze and map out the correlation of the CO2 emission coefficients for each road slope, we determined the coefficient of the CO2 emissions using multiple linear regression analysis and validated this using Huber–White robust standard errors for heteroscedasticity. This method was more cost-efficient and time-efficient compared to the conventional approaches. We also created CO2 emission maps with risk points for health effects, and we propose policy designs and plans to manage the traffic level in each of these areas prone to higher levels of such emissions.

The objective of this study was to estimate the sensitivity of spirit quantity demanded for price and income changes in Montenegro and to show the effectiveness of taxation-policy changes in the reduction of spirit consumption. It is the first study on this topic in Montenegro, where adverse effects of alcohol are recognized as an important obstacle in achieving Sustainable Development Goals (SDGs). The price elasticity of spirits was estimated using Deaton’s methodology on the Household Budget Survey (HBS) data in the period of 2006–2017. Cigarettes were included as a control variable as, along with spirits, they are one of the most harmful substances used in Montenegro. Using these results, we simulated the effects of spirit use on public revenue. The results show that the spirits’ own price elasticity equaled −0.45, while the cross-price elasticity equaled −0.17, showing that spirits and cigarettes are complementary goods. These results, along with elasticities calculated by sex (male, −0.55; female, −0.5), income groups (low income, −1.16; middle-income, −0.46; high-income, −0.26), and for the working-age group (−0.74), demonstrate that an increase in excise taxes could be a very efficient tool in decreasing the adverse effect of spirits and cigarettes on household member’s productivity, health, and budget, which is in line with SDGs. An efficient road map for sustainable development for Montenegro must include the reduction of health-harmful substance use through excise tax increase.

In recent years, the health conditions of the elderly (the middle-aged and the old, which for this study means people over 50 years of age) have deteriorated along with the aggravation of air pollution, which led to the change of medical insurance costs. This phenomenon is particularly prominent in developing countries, such as China. A total of 15,892 research subjects from 56 prefecture-level cities in 23 provinces were collected from the database of China Health and Retirement Longitudinal Survey (CHARLS). We investigated the effects of air pollution, physical health, and medical insurance costs among three mechanisms using logistics and Ordinary Least Squares (OLS) hybrid cross-sectional regression, and we conducted a robust test. Overall, two pollutants, namely, PM10 and NO2, respectively showed an “inverted U-shaped” and “positive U-shaped” influencing path to health. In addition, when we studied the mechanism of air pollution affecting medical insurance costs, we found that air pollution can affect medical insurance costs through affecting self-rated health, and that the impact path is related to different diseases to some extent. At the same time, there was a certain negative correlation between air pollution and medical insurance: The higher the degree of air pollution, the worse the self-rated health, and the fewer opportunities there are to purchase medical insurance. It can be seen that air pollution affects the physical health of middle-aged and elderly people, thus indirectly and negatively affecting the medical insurance cost. Further research also found that the types of air pollutants in southern and northern China showed some differences. Specifically, NO2 and SO2 were the pollutants that harm the health of the elderly in the south and north, respectively.

Most municipal solid waste (MSW) in Russia is disposed of in landfills, and only a relatively small fraction is recycled. The landfilling of waste leads to greenhouse gas (GHG) emissions, and air and groundwater pollution. However, recently, there have been some initiatives to improve waste management in the country. We assessed the economic and environmental benefits of waste recycling in the Murmansk region, in which a new waste recycling plant has been operating since 2019. We found that MSW recycling in the Murmansk region has induced a small, positive, job creation effect and could potentially lead to a non-negligible reduction in GHG emissions. Extrapolating the results from this case study to the country level, we found that recycling landfilled MSW in Russia could save approximately 154 million tons of GHG emissions in carbon dioxide equivalents annually, which is comparable to the total CO2 emissions from Algeria. The positive environmental and health-related impacts from the extensive implementation of MSW recycling in the country could be substantial. From this case study, we also learned that one of the biggest challenges for the waste recycling company in the Murmansk region is finding profitable markets for recycled materials. Moreover, due to the high investment and operational costs, recycling MSW led to a substantial increase in communal fees. However, there is potential to make waste recycling more cost effective. Most MSW in the Murmansk region is still separated at the recycling plant, while separating waste at the source could substantially reduce operational costs. Other challenges in the large-scale implementation of MSW recycling in Russia, such as a lack of investments and the population’s willingness to recycle waste, are also discussed.

In the backdrop of the ‘dual carbon goal’, which aims to promote sustainable development of China, adoption of new energy vehicles (NEVs) is an important measure to help improve the environment, so it is of great significance to investigate the purchase intention of NEVs. Previous studies have established that subsidies and various product attributes could affect consumers’ purchase intention toward NEVs. As government subsidies have been on the decline in recent years, product attributes of NEVs need to be given more attention. However, there have been limited studies that quantitatively analyze the impact of product attributes of NEVs on purchase intention. Therefore, to fill this gap and help further expand the NEV market, this study investigated consumers’ adoption of NEVs empirically from the perception of product attributes. A questionnaire survey and structural equation model (SEM) were used for data collection and analysis. The results indicate that (1) both the functional and symbolic attributes of NEVs had a significant positive impact on consumers’ purchase intention; (2) both the functional and symbolic attributes of NEVs had a significant positive impact on consumers’ purchase intention through consumers’ perceived value; and (3) citizens’ environmental awareness positively moderated the relationship between products attributes and purchase intention. According to the results, to meet consumers’ needs of daily driving and self-image expression, new energy vehicle enterprises need to focus on improving the products in both functional and symbolic aspects by using various marketing strategies.

The big-health industry is an emerging industry with huge market potential, which plays an important role in economic growth and industrial structure adjustment. After years of development, the big-health industry in the Binhai New Area has begun to take shape and become an important force to promote the high-quality development of regional economy. This paper tries to use the SWOT and gray correlation degree analysis method to explore the correlation degree between the big-health industry and its sub-industries, so as to provide a reference for the Binhai New Area to create deep health resources, release the development potential of the big-health industry, and promote the sustainable development of the regional economy and its people. It is estimated that in the next five years, the per-capita GDP of Beijing and Tianjin will exceed USD 15,000, and the life expectancy of the population will exceed 80 years. The Beijing–Tianjin–Hebei region will enter the high level of human development (human development index greater than 0.8). With the improvement of living standards, people’s demand for health will rise sharply, and the market prospects are broad. The Binhai New Area should seize this opportunity to accelerate the development of the big-health industry, to create momentum for regional sustainable development, and to create happiness for its people. The main objective of this study is to ascertain the sustainable development status of the big-health industry in the Tianjin Binhai New Area, as well as the direct relationship between the level of economic development and the development of the big-health industry, to lay a good economic foundation for the vigorous development of the big-health industry.

This paper explores the potential of concrete material to accumulate toxic trace elements using ablative laser technology (ICP-MS). Concrete existing in offshore structures submerged in seawater acts as a sink for hazardous metals, which could be gradually released into the ocean creating pollution and anoxic conditions for marine life. Ablative laser technology is a valuable tool for depth profiling concrete to evaluate the distribution of toxic metals and locate internal areas where such metals accumulate. Upon rapid degradation of concrete these “hotspots” could be suddenly released, thus posing a distinct threat to aquatic life. Our work simulated offshore drilling conditions by immersing concrete blocks in seawater and investigating accumulated toxic trace metals (As, Be, Cd, Hg, Os, Pb) in cored samples by laser ablation. The experimental results showed distinct inhomogeneity in metal distribution. The data suggest that conditions within the concrete structure are favorable for random metal accumulation at certain points. The exact mechanism for this behavior is not clear at this stage and has considerable scope for extended research including modeling and remedial studies.

To be “connected” is “to care”, because how and what we care about is influenced, and influences, what we are connected with. Emotional connection predicts environmental concern and children exposed to green environments take this appreciation of nature with them into adulthood. However, the majority of the human population is now living within urban areas, where opportunities for people to interact and bond with nature are greatly diminished, thereby potentially threatening the liveability of cities into the future. Connection with nature has been shown repeatedly to benefit human wellbeing and predict pro-environmental behaviours. By definition “nature” includes urban agriculture, which is also an integral component of a city’s foodscape, thereby providing opportunities to improve the wellbeing of city inhabitants as well as help ensure food security. This will only be attainable if the next generation has an emotional connection to nature, and the necessary life skills to help them enter adult life as informed food citizens who make healthy and sustainable decisions for themselves as well as others. This paper reviews existing literature on foodscape (or one’s food environment) and biophilia (the love of life or living systems) to highlight the need for inter-disciplinary research that combines urban agriculture and food literacy to ensure future food security and wellbeing of urban inhabitants.
