Nanotechnology is nowadays very much successful in producing specifically functionalized nano-sized particles. In this work, copper nanoparticles were prepared by reduction method which is greener and environmentally suitable, cheap and best as compared to other conventional methods, particularly in the context of COVID in globalized world. The formation and size of copper nanoparticles was evidenced by the X-ray diffraction and transmission electron microscopy. The very high surface area of 35–50 m²/gm and very small crystallite sizes of 5–15 nm of these metal nanoparticles is mainly responsible for their effective involvement in removal of carbon dioxide gas as one of major hazardous pollutants from the environment. This chapter, as its main objective, mainly focuses on utility of nano technology and its beneficiary in creating a sustainable environment in economic world. Apart from laboratory experimental procedure and characterizations for preparation of copper nanoparticles, appropriate research methods such as simple statistical, econometric tools and mathematical tools have been used for economic analysis. However, as major findings of the results, developed countries have been successful in maintaining a sustainable human development, in spite of having higher per capita income (PCI) growth as compared to the role of developing countries with lower PCI in this global world.

This chapter proposes frugal eco-innovation as an eco-efficient way into which firms might shift their existing business models, exploring how firms are able to cut costs and reduce negative environmental impacts simultaneously.

This work introduces the concept of frugal eco-innovation based on numerous examples about how several European companies are adopting this management perspective. These examples are obtained from these companies’ public environmental reports.

A summary of how cost reduction could be achieved by firms on the basis of frugal eco-innovation; further, the pathway for how managers could achieve an effective implementation of frugal eco-innovation.

By developing frugal eco-innovation, managers are able to benefit from a management alternative that is ecologically sustainable and economically profitable.

This work highlights how frugal eco-innovation could benefit, on the one hand, firms via the achievement of cost reduction and, on the other hand, the society in general via the diminution of the negative environmental impacts generated by the business activity.

This work analyses a management orientation that could be implemented in order to shift business models towards a more ecological production, highlighting how firms are able to do more with less.

At the core of understanding the practice of marketing sustainable tourism lies an appreciation not only of the evolution of the concept of sustainability, but also of the co-productive process between consumer and producer. This chapter establishes a conceptual overview on sustainable tourism and its alternative terms (ecotourism, responsible tourism, soft tourism, ethical tourism). Its origins stem from the pivotal works of the Brundtland Report. The author considers the complex structures that interact with the tourism industry, such as the social, environmental and economic impacts of tourism in vulnerable or sensitive climates. For example, in Central Thailand, cities such as Bangkok have experienced rapid urbanisation as well as burgeoning tourism. This has resulted in high levels of air pollution from traffic congestion and manufacturing, while escalation in the tourism industry places burdens on waste management systems. Further strains on waste management in both the Eastern and Southern regions, particularly along the coastlines, which suffer from high levels of coastal litter, are attributed to the rising tourism industry – a process other popular destinations have undergone, such as Costa Rica. Examination of cases such as Thailand will elicit further discussion of public awareness of the impacts of the tourism industry in vulnerable climates. Lastly, the chapter will look at cases of demotion or de-marketing of tourism in certain regions in order to limit the number of visitors, such as that of the Blue Mountains National Park in Australia. In addition to the case studies reviewed in this chapter, there is a practice exercise in developing an environmental performance index, based on existing data on country-specific environmental performance.
