This open access book states that the endemic societal faultlines of our times are deeply intertwined and that they confront us with challenges affecting the security and sustainability of our societies. It states that new ways of inhabiting and cultivating our planet are needed to keep it healthy for future generations. This requires a fundamental shift from the current anthropocentric and economic growth-oriented social contract to a more ecocentric and regenerative natural social contract. The author posits that in a natural social contract, society cannot rely on the market or state alone for solutions to grand societal challenges, nor leave them to individual responsibility. Rather, these problems need to be solved through transformative social-ecological innovation (TSEI), which involves systemic changes that affect sustainability, health and justice. The TSEI framework presented in this book helps to diagnose and advance innovation and change across sectors and disciplines, and at different levels of governance. It identifies intervention points and helps formulate sustainable solutions for policymakers, administrators, concerned citizens and professionals in moving towards a more just and equitable society.

Environmental unsustainability is due to both structural features and historically specific characteristics of industrial capitalism resulting in specific patterns of production and consumption, as well as population growth. Sustainability literature criticises the established corporate and political power hegemonies, interested in maintaining economic growth, as well as inability or unwillingness of citizen-consumers to counteract these hegemonic tendencies. Yet, official policies are still targeted at social and economic ‘development’ as a panacea for unsustainability challenges. Instead, renewed accent on social and economic objectives are outlined by a set of sustainable development goals (SDG) that include objectives of fighting poverty, promoting better health, reducing mortality, and stimulating equitable economic growth. What is less commonly critiqued is the underlying morality of unsustainability and ethical questions concerned with the ‘victims of unsustainability’ outside of socioeconomic discourse. The achievement of SDG goals, as will be further elaborated on in this article, is unlikely to lead to greater social equality and economic prosperity, but to a greater spread of unsustainable production and consumption, continuous economic as well as population growth that has caused environmental problems in the first place and further objectification of environment and its elements. This article argues that an invocation of ethical duty toward environment and its elements is required in order to move beyond the current status quo. Such ethical approach to unsustainability can effectively address the shortcomings of the mainstream sustainability discourse that is mainly anthropocentric and therefore fails to identify the correct locus of unsustainability.

Food production and consumption have a range of sustainability implications, including their contribution to global emissions of greenhouse gases (GHGs). As some foodstuffs entail higher GHG emissions than others, managing their use in tourism-related contexts could make a significant contribution to climate change mitigation. This article reviews the carbon intensity of selected foods and discusses how foodservice providers could adapt their practices. It shows that even though food management could substantially reduce the GHG emissions of foodservice providers, its application is currently hampered by the complexity of food production chains and a lack of dependable data on the GHG intensity of foodstuffs. Nevertheless, it is possible to make a number of recommendations in respect of how foodservice providers can better purchase, prepare and present foods. Further research is now needed to refine and extend our understanding of the contribution that food management can make to reducing tourism's carbon 'foodprint'.

Paper sludge contains papermaking mineral additives and fibers, which could be reused or recycled, thus enhancing the circularity. One of the promising technologies is the fast pyrolysis of paper sludge, which is capable of recovering > 99 wt.% of the fine minerals in the paper sludge and also affording a bio-liquid. The fine minerals (e.g., ‘circular’ CaCO3) can be reused as filler in consumer products thereby reducing the required primary resources. However, the bio-liquid has a lower quality compared to fossil fuels, and only a limited application, e.g., for heat generation, has been applied. This could be significantly improved by catalytic upgrading of the fast pyrolysis vapor, known as an ex-situ catalytic pyrolysis approach. We have recently found that a high-quality bio-oil (mainly ‘bio-based’ paraffins and low-molecular-weight aromatics, carbon yield of 21%, and HHV of 41.1 MJ kg-1) was produced (Chem. Eng. J., 420 (2021), 129714). Nevertheless, catalyst deactivation occurred after a few hours’ of reaction. As such, catalyst stability and regenerability are of research interest and also of high relevance for industrial implementation. This project aims to study the potential of the add-on catalytic upgrading step to the industrial fast pyrolysis of paper sludge process. One important performance metric for sustainable catalysis in the industry is the level of catalyst consumption (kgcat tprod-1) for catalytic pyrolysis of paper sludge. Another important research topic is to establish the correlation between yield and selectivity of the bio-chemicals and the catalyst characteristics. For this, different types of catalysts (e.g., FCC-type E-Cat) will be tested and several reaction-regeneration cycles will be performed. These studies will determine under which conditions catalytic fast pyrolysis of paper sludge is technically and economically viable.
Client: Blue Plan regional activity centre (UNEP/MAP), subcontracted through TEC Conseille, Marseille As part of a regional workshop organized by the Blue Plan in July 2008, one of the conclusions of the Group "Tourism and Climate Change” was the need for saving energy in tourism transportation and particularly of air transport, as air transport is responsible for the largest share of greenhouse gas emissions caused by tourism. In the period 1998-2005, the share of international arrivals by air in the Mediterranean area rose from 23% to 40%, respectively, or in numbers, from 47 to 122 million tourists. Some countries, particularly islands, almost entirely depend on air transport for their international tourism. For example in 2005 air transport is used by 87%, 78%, 73%, 64% and 51% of international tourists arriving in, respectively, Israel, Egypt, Spain, Tunisia and Morocco. According to Plan Bleu forecasts on international arrivals, assuming that the share of air transport remains the same, the number of tourists travelling by plane will reach over 158 million by 2025. Given the role of aviation in the emissions of greenhouse gases (GHG), such a development is clearly not sustainable in the light of the necessary reduction of emissions to avoid dangerous climate change. The overall aim of the study is to inform policy makers and entrepreneurs in both destination and in origin countries, on possible options to reduce emissions of greenhouse gases from air travel, while at the same time not impairing the economic development of tourism. To do this, CSTT has developed a tourism scenario model for all countries with Mediterranean coasts describing inbound and outbound international tourism and domestic tourism by all available transport modes and giving both contributions to GDP and total GHG emissions. This model responses to global mitigation policies (increasing the cost of carbon emissions) as well as national policies (taxes, subsidies and changes in transport quality per transport mode). Using the model both global and national policies can be assessed as well as the risks of global mitigation policies for specific countries.
