Currently, waste is regarded as a symptom of inefficiency. The generation of waste is a human activity, not a natural one. Currently, landfilling and incinerating wastes are common waste management techniques; but the use of these methods, in addition to wasting raw materials, causes damage to the environment, water, soil, and air. In the new concept of “Zero Waste” (ZW), waste is considered a valuable resource. A vital component of the methodology includes creating and managing items and procedures that limit the waste volume and toxicity and preserve and recover all resources rather than burning or burying them. With ZW, the end of one product becomes the beginning of another, unlike a linear system where waste is generated from product consumption. A scientific treatment technique, resource recovery, and reverse logistics may enable the waste from one product to become raw material for another, regardless of whether it is municipal, industrial, agricultural, biomedical, construction, or demolition. This chapter discusses the concept of zero landfills and zero waste and related initiatives and ideas; it also looks at potential obstacles to put the ZW concept into reality. Several methods are presented to investigate and evaluate efficient resource utilization for maximum recycling efficiency, economic improvement through resource minimization, and mandatory refuse collection. One of the most practical and used approaches is the Life Cycle Assessment (LCA) approach, which is based on green engineering and the cradle-to-cradle principle; the LCA technique is used in most current research, allowing for a complete investigation of possible environmental repercussions. This approach considers the entire life cycle of a product, including the origin of raw materials, manufacturing, transportation, usage, and final disposal, or recycling. Using a life cycle perspective, all stakeholders (product designers, service providers, political and legislative agencies, and consumers) may make environmentally sound and long-term decisions.

A tourist destination represents a dynamically regulated system that evolves in space and time. Therefore, it is necessary to anticipate various system reactions to internal and external influences, so that actions can be directed towards the specific goals of supply and demand for products of tourist destinations. A successful process in the life cycle of tourist destination product planning is based on the anticipation and awareness of all participants of supply and demand, as the sustainability values must be perceived within the framework of an integrated destination product. It is necessary to examine assumptions and features of the market valuation of destination business processes from an economic, social and environmental standpoint in line with the principles of sustainable development. This implies the creation of a methodological basis for the recognition, measurement and tracking of complex processes and synergic effects, important for the development of relevant management information-based structures and functions. Measuring the eco-efficiency of a tourist destination represents the basis for building a system of reporting on changes and impacts individual business subjects deployed in the environment. An integrative information system of tourist destinations should provide information on the eco-efficiency of individual business processes, activities, products or a Strategic Business Unit's (SBU's) entire life cycle. Obtained information allows for the preparation of an information basis for reporting on environmental aspects within the system of tourist destinations sustainable development reporting.

In the 1930s, chlorofluorocarbons (CFCs) were developed as safe, non-reactive alternatives to toxic and explosive refrigerants and propellants such as ammonia, chloromethane, and sulfur dioxide. American engineer Thomas Midgley famously demonstrated these properties by inhaling Freon (CFC-12) and blowing out a candle with it. He was presented with many awards for his discoveries, such as the Perkin, Priestley, and William Gibbs medals. In today's jargon, CFCs might have been called an eco-innovation, because they provided solutions to several environmental issues. However, CFCs solved environmental problems by creating others. In 1974, Sherwood Rowland and Mario Molina published their pathbreaking research that demonstrated CFCs were depleting the ozone layer. In 1989, the Montreal Protocol, which regulates a global phaseout of CFCs, entered into force. A few years later, in 1995, Rowland and Molina received the Nobel Price in Chemistry. The new substitutes for CFCs, hydrofluorocarbons (HFCs), have no known effects on the ozone layer but are extremely potent greenhouse gases (GHGs) and thus subject to the Kyoto Protocol.

Electric cars represent the most energy efficient technical option available for passenger cars, compared to conventional combustion engine cars and vehicles based on fuel cells. However, this requires an efficient charging infrastructure and low carbon electricity production as well. Combustion engine cars which were converted to electric cars decreased lifecycle CO₂-equivalent emissions per passenger-km travelled down to one third of before, when powered by green electricity. However, through an analysis of 78 scientific reports published since 2010 for life cycle impacts from 18 aggregated impact categories, this chapter finds that the results are mixed. Taken together, however, the reduced environmental impacts of electric cars appear advantageous over combustion engine cars, with further room for improvement as impacts generated during the production phase are addressed. When it comes to battery components, Cobalt (Co) stands out as critical. Assessing the impact of electric cars on the local air quality, they are not ‘zero emission vehicles’. They emit fine dust due to tyre and brake abrasion and to dust resuspension from the street. These remaining emissions could be easily removed by adding an active filtration system to the undercarriage of electric vehicles. If electric cars are operated with electricity from fossil power plants nearby, the emissions of these plants need to be modelled with respect to possibly worsening the local air quality.

The effects of the COVID-19 pandemic on cities have transformed the lives of urban societies across the globe. One of such effects has been the redefinition of access and urban mobility patterns, exposing divides and inequalities along the lines of class, gender and social positions. In Latin America, long-term lockdowns and widespread containment-oriented restrictions have deepened already acute conditions of poverty and deprivation. Low-income and socially vulnerable households and individuals in countries such as Colombia find themselves unable, or in a disadvantaged position, to work from home, access goods and services securely and avoid transport modes that increase exposure to contagion. This chapter examines inequalities in urban mobility and access to essential opportunities in urban settings in Colombia, through data collected from 3,900 respondents to a web survey organised during the national lockdown in the country in April 2020. The chapter presents a Latent Class Analysis model exploring how intersecting differences in class, gender, ethnicity, age and other relevant socioeconomic characteristics, influence the degree of adaptability and capacity to adapt to the challenging conditions posed by COVID-19 for physical travel and carrying out everyday activities. Building on three distinct classes of mobility and access-related conditions, the chapter reflects on structural inequalities associated with Colombian cities’ urban form, functional and productive structures and its wide social gaps. The chapter builds on empirical findings to reflect on urban policy and discuss avenues for addressing social and spatial inequalities worsened by the pandemic.

This study aims to reveal the perspectives of the management and senior accountants on the subject regarding the effects of climate change on the business world, within the framework of utilisation of tools like strategic cost management and strategic management. An electronic form was sent repeatedly to the e-mail addresses of public companies listed on the Borsa Istanbul (BIST), which were obtained from the Public Disclosure Platform (PDP), between June 2018 and June 2019. According to the data obtained from the survey of this study, it is not possible to comment that these tools are effectively utilised in Turkey. Besides, it is also early to say that top management is fully aware of the need to manage climate change. This study contributes to the literature by revealing the view of management accountants and finance experts in Turkey on climate change.

Constructing and evaluating behavioral science models is a complex process. Decisions must be made about which variables to include, which variables are related to each other, the functional forms of the relationships, and so on. The last 10 years have seen a substantial extension of the range of statistical tools available for use in the construction process. The progress in tool development has been accompanied by the publication of handbooks that introduce the methods in general terms (Arminger et al., 1995; Tinsley & Brown, 2000a). Each chapter in these handbooks cites a wide range of books and articles on specific analysis topics.
