This chapter tests theoretically and empirically the existence of a stable relationship between energy consumption and CO2 emissions. Based on microeconomics and physics, a model has been specified and applied to annual data for twenty countries, which representing 61 percent of the world’s population in 2018, over the period 1995–2015. The data are from the International Energy Agency (2019) and econometric techniques including panel data and causality tests have been used. The results indicate that there is a causal relationship between energy consumption and CO2 emissions. In general, consumers cannot directly change emissions caused by production processes, but they can act on emissions caused by their own domestic energy consumption. Approximately three quarters of domestic energy consumption is due to heating and domestic hot water consumption. Taking into account the lower emissions and the lower economic cost of the initial investment, four potential energy systems have been selected for use in heating and domestic hot water. Their social returns have been assessed across nine of the twenty countries in the sample over a lifecycle of 25 years from 2018: France, Portugal, Ireland, Spain, Iceland, Germany, United Kingdom, Morocco and the United States. Cost-benefit analysis techniques have been used for this purpose and the results indicate that the use of thermal water, where applicable, is the most socially profitable system among the proposed systems, followed by natural gas. The least socially profitable systems are those using electricity.

Purpose: Due to technological developments, industrialisation, irregular urbanisation, rapid population growth, and unconscious consumption, environmental problems have been on the agenda of activists, not for profit organisations, businesses, and governments for the last 20 years. Global warming, climate change, and ozone layer depletion are among the environmental problems which are the most threatening to life on earth. What is underlying these three problems is greenhouse gases emitted into atmosphere. Carbon footprint is a measure of carbon emission. The amount of carbon footprint is closely related to consumption styles as well as production. Unconscious life styles and consumption habits of consumers increase the amount of carbon footprint produced. Together with the rise of environmental problems, the concept of sustainable consumption has become very important. In the most simple of terms, sustainable consumption means consumption without consuming natural resources and this will play an important role in reducing carbon footprint.

Aim: In this chapter, keeping in mind the context of sustainable consumption, the concept of carbon footprint is explained as well as the methods for reducing carbon footprint arising from consumption, in a bid to bring strong awareness of these issues to consumers.

Methodology: To do this a literature review was carried out and methods of reducing carbon footprint were examined and discussed.

Findings: Consumers play an important role in reducing the amount of carbon footprint arising from individual consumption.

Originality of the Study: Most studies are carried out on the carbon footprint resulting from businesses and on carbon footprint calculation and determination of carbon footprint of products. Therefore, this study is specific in that it focusses on the carbon footprint of consumers.

Implications: Studies show that one of the important factors increasing carbon footprint is the unconscious acts of consumers relating to the environment. As long as this unconscious consumption model continues, the amount of carbon footprint will also increase. Hence, consumers need to know which activities reduce the amount of carbon footprint.

This chapter discusses the global challenge to reduce greenhouse gas (GHGs) emissions to net zero by 2050. It explains what net zero means and how it is calculated, together with some of the debate around the suitability of the target to maintain global warming levels within ‘acceptable’ boundaries. The chapter then presents some of the opportunities and challenges that transitioning towards net zero will pose to countries and their inhabitants, in terms of changes to policies, products, processes and behaviours that will be required to attain the target. It then discusses the need for a strategy to achieve net zero across different sectors of society and provides a few suggestions of tools and concepts that could be adopted to support the changes necessary, such as planning for change, the Sustainable Development Goals (SDGs), integrated reporting and the circular economy. The chapter concludes with a reflection on the need for the net zero target and how it is our collective responsibility to support the challenging transition to net zero for the benefit of all.

Ostensibly the Carverian argument is based on the following premise, which is treated as an axiom:Human beings like other living creatures seem to be driven by a force that they neither understand nor care to resist, to keep on living, to consume food and transform it into human energy, and to increase their numbers, thus, in every way, enlarging the stream of human energy. In short, they act unconsciously, driven by their own nature, precisely as they would act consciously if they were convinced by unanswerable logic that the most valuable thing in the world was human energy or human life, and the most profitable thing in the world was to transform the largest possible sum of solar energy into human energy.

This chapter investigates public value co-creation by researching how people make experience of public value creation across sectors and from a place perspective. The study draws on a qualitative thematic analysis conducted on a crowdsourced dataset of more than 1,000 case examples of place leadership provided across three years (2017–2019) by a sample of students. The results identify 21 themes (ways of co-creating public value from four realms of place-based leadership – political, community, managerial and business). We contribute to public value co-creation by better understanding what are (or might be) the contributions and the rewards to engage public, private non-profit and citizens in processes of co-creation within collaborative governance.

This article critically reviews the latest Global Reporting Initiative (GRI) guidelines and recommended sustainability topics for public agencies, and presents normative argument by using Gray’s (2006) ecological and eco-justice (EEJ) approach to produce public value inscriptions of sustainability to represent sustainable public value.

The study presents a critical analysis and discussion of the changes to the GRI G4 and sustainability topics for public agencies from a managerialistic and EEJ approach.

We observe that the GRI continues to evolve while paying scant attention to furthering the Sector Supplement for Public Sector Agencies as it remains in its pilot form since its inception in 2005. Changes to the GRI are somewhat enlightening because several of the changes do begin to address a more comprehensive view of how any organization, including public agencies, can contribute to an EEJ approach to sustainability.

In the future it is important to be aware that, as inscriptions, the GRI guidelines have the potential power to influence how managers in public agencies approach sustainability. As Dumay, Guthrie, and Farneti (2010) previously argued, if guidelines continue to approach sustainability from a ‘managerialistic’ approach then there is little hope of public sector agencies adopting EEJ practices. We argue that organizations should act referring to Gray’s EEJ approach.

This chapter presents an overview of the Bitcoin and its impacts on the environment and economics from the viewpoint of carrying out a systematic analysis of the literature related to the environmental and economic effect of digital currency. It is aimed to summarize and critically examine the points of view regarding Bitcoin mining, considering its effects on global warming and the social environment, employing peer-reviewed data associated through literatures. As a result, this study provides the chance to analyze the set of knowledge regarding the effects of the Bitcoin mining procedure on the ecosystem in regard to energy use and CO₂ emissions regarding unit root tests and causality test based on nonlinear models. The results show that there exists a nonlinear causal relationship between statistics on Bitcoin mining and the CO₂ emissions. The results also imply that Bitcoin remains to be a tool utilized in the economic environment for a range of objectives despite high energy consumption and some negative environmental impact within the scope of renewable energy; hence, authorities would take Bitcoin mining impacts into account to reduce CO₂ emissions.

The expected operational lifespan of modern buildings has become disturbingly short as buildings are replaced for reasons of changing cultural expectations, style, serviceability, locational obsolescence and economic viability. The same buildings, however, are not always physically or structurally obsolete; the materials and components within them are very often still serviceable. While there is some recycling of selected construction materials, such as steel and concrete, this is almost always in the form of down cycling or reprocessing. One significant impediment to reuse is that buildings are not designed in a way that facilitates easy recovery of materials and components. This chapter explores the potential for the recovery of materials and components if buildings were designed for such future recovery, utilizing the strategy of design for disassembly. As well as assessing material waste, this chapter presents research into the analysis of the embodied energy in buildings, highlighting its significance in comparison with operational energy. Analysis at material, component and whole-of-building levels shows the potential benefits of strategically designing buildings for future disassembly to recover this embodied energy. Careful consideration at the early design stage can result in the deconstruction of significant portions of buildings and the recovery of their potential through higher order reuse and upcycling.
