“Green Cities” are cities with the ultimate goal of achieving a net zero-carbon footprint in energy, transportation, architecture, and the activity cost chain of businesses. These cities define the future of our planet by emphasizing the efficient use of resources and the well-being of communities. This study focuses on “Green Cities” and the restaurant industry. It examines the beliefs of restaurant owners/managers on the positive impact of sustainability practices on financial situation, reputation, and attraction of customers, and the relationship between such beliefs and the extent of engagement in sustainability practices. The research also explores whether declaring a city “Green” enhances the sustainability practices in that city. The results indicate that the restaurant owners/managers in all three studied cities strongly believe that sustainability practices enhance the financial performance, reputation of the restaurant, and attraction of customers, yet a significant percentage of the wastes and by-products of the operations of the studied restaurants are discarded. In addition, the results of the study show no significant impact on sustainability practices in the studied restaurants for the declared “Green” cities of Providence (U.S.) and Nancy (France) versus the city of Springfield (U.S.). The study concludes by highlighting the potential reasons underlying the lack of sustainability practices in the restaurant industry and proposes recommendations that can enhance such practices in this industry.

The number one leading cause of death in 2017 for Americans was cardiovascular disease (CVD), and health disparities can exacerbate risks. This study evaluates the 2018 Behavioral Risk Factor Surveillance System (BRFSS) (n = 437,436) to estimate population risks for behavioral, socio-economic, psychological, and biological factors. A general linear model with a quasi-binomial link function indicated higher risks for the following groups: smokers (odds ratio, OR = 0.688), individuals with higher body mass index scores (OR = 1.023), persons unable to work (OR = 2.683), individuals with depression (OR = 1.505), workers who missed more days due to mental issues (OR = 1.12), the elderly, males (OR = 1.954), those in race categories “indigenous Americans, Alaskan non-Hispanics”, “Black Hispanics,” or “other, non-Hispanic,” and individuals with lower income. Surprisingly, increased consumption of alcohol was not found to be a risk factor as in other studies. Additional study of alcohol risk factors is needed. Further, Black non-Hispanics were associated with lower rates of CVD/MI (myocardial infarction), a finding that is supported by recent evidence of more unhealthy behaviors in other races. The results of this study highlight 2018 CVD/MI disparities based on the BRFSS and suggest the need for additional policy interventions including education and providing increased access to health care for the disadvantaged. The principles of beneficence and justice require policy interventions such as these.

This research explores the relationship between Hofstede’s femininity cultural dimension of quality of life and the masculinity cultural dimension of drive for success manifested by materialistic wealth by investigating the market value of the publicly traded firms appearing on the Dow Jones Sustainability Indices (DJSIs). The firms added to the DJSIs between the years 2010–2019 in countries with the femininity cultural dimension indicated by scores of ≤42, were selected for the first part of this study. In addition, France, with a masculinity score of 43 and Japan, with the highest masculinity score of 92, were chosen for comparison with the results from the countries with the femininity cultural dimension. The findings of this study indicate that companies in developed and emerging countries with the femininity cultural dimension show significant positive impact on their market values when added to the DJSIs. The publicly traded firms in France show a significant negative impact on their market values when added to the DJSIs. On the other hand, Japanese companies on the addition lists of DJSIs show a significant positive impact on their market values, despite Japan having the highest Hofstede masculinity score, a potential sign of cultural change in Japan.

Sustainability and corporate social responsibility (CSR) strategies of companies delineate the health and the welfare of the communities across the globe. The two major goals of this study are (1) To explore the relationship between the environmental regulations, market value, and adoption of sustainability and CSR strategies of the publicly traded firms listed on the Dow Jones Sustainability Indices (DJSI) and (2) To examine the impact of being added to or deleted from DJSI per different market sectors for the firms in the U.S. and the European Union (EU). The selected starting window, the year 2015, for studying the impact of addition to or deletion from the DJS indices was the Paris Accord proposal by the EU and strict sustainability regulations of the EU versus the U.S. We used event study methodology and regression analyses to explain the cumulative abnormal returns utilizing firms’ characteristics and specific market sectors. In addition, the other focus of the study was on heavy (polluting) industries and investigating if the addition to or deletion of the firms in these industries from the sustainability indices had an impact on the market value. The findings of this study reveal no impact of the environmental rules and regulations on adopting sustainability and CSR strategies by either the EU or the U.S. firms. The novel findings of this study indicate a significant negative impact on the market value of firms in heavy industries, Energy, Basic Materials, and Utilities when added to the DJS indices. The study discusses the underlying reasons for these differences and proposes strategies to enhance the impact of addition to or deletion from the DISI to increase firms’ commitments to sustainability and CSR strategies and altering the attitudes of the investors.

The focal point of this research is to compare two of the largest global organizations’ sustainability indices and scores, namely Dow Jones Sustainability Indices (DJSIs) and Standard & Poor’s Global (S&P Global) ESG scores (environmental, social, and governance), which rank companies based on their sustainability practices, and to learn if they correspond to each other. Considering that Germany is the hub of large companies from leading global industries, this research compares the ESG scores of the German companies that appear on the Dow Jones Sustainability Indices. Several statistical analyses are conducted to determine if the German companies on the DJSIs correspond with high ESG scores. The years under consideration are 2018 through 2023. The results of this research indicate that DJSIs and ESG scores do not tell the same story and there are discrepancies regarding the sustainability practices of the studied companies that are added to the DJSIs and the assigned high ESG scores by S&P Global.

This study investigates plastic waste management, focusing on Japan. The volume of plastic waste in Japan is more than eight million tons, and less than a quarter of the plastic waste is subjected to recycling. Considering that Japan is an archipelago consisting of a combination of four large islands and numerous smaller ones, plastic waste that enters the ocean poses significant threats to marine life, birds, other living beings, and beach pollution. This research explores the underlying factors that have made Japan one of the highest users of plastic. In addition, this study evaluates different strategies that are utilized in Japan to deal with the reduction in plastic utilization and plastic waste. The final section of the study proposes strategies that can reduce utilization of plastic and production of plastic waste and the new and future outlook for replacement of plastic.
