An analysis of the current developments and scenarios for the transition to a fossil-free energy society this century

This century, greenhouse gas emissions such as carbon dioxide, methane and nitrogen oxides must be significantly reduced. Greenhouse gases absorb and emit infrared radiation that contributes to global warming, which can lead to irreversible negative consequences for humans and the environment. Greenhouse gases are caused by the burning of fossil fuels such as crude oil, coal, and natural gas, but livestock farming, and agriculture are also to blame. In addition, deforestation contributes to more greenhouse gases. Of the natural greenhouse gases, water vapor is the main cause of the greenhouse effect, accounting for 90%. The remaining 10% is caused from high to low by carbon dioxide, methane, nitrogen oxides, chlorofluorocarbons, and ozone. In addition, there are industrial greenhouse gases such as fluorinated hydrocarbons, sulphurhexafluoride and nitrogen trifluoride that contribute to the greenhouse effect too. Greenhouse gases are a major cause of climate change, with far-reaching consequences for the welfare of humans and animals. In some regions, extreme weather events like rainfall are more common, while others are associated with more extreme heat waves and droughts. Sea level rise caused by melting ice and an increase in forest fires are undesirable effects of climate change. Countries in low lying areas fear that sea level rise will force their populations to move to the higher lying areas. Climate change is affecting the entire world. An estimated 30-40% o f the carbon dioxide released by the combustion of fossil fuels dissolves into the surface water resulting in an increased concentration of hydrogen ions. This causes the seawater to become more acidic, resulting in a decreasing of carbonate ions. Carbonate ions are an important building block for forming and maintaining calcium carbonate structures of organisms such as oysters, mussels, sea urchins, shallow water corals, deep sea corals and calcareous plankton.

Power-to-ammonia: rethinking the role of ammonia – from a value product to a flexible energy carrier (FlexNH3)

This report focuses on the feasibility of the power-to-ammonia concept. Power-to-ammonia uses produced excess renewable electricity to electrolyze water, and then to react the obtained hydrogen with nitrogen, which is obtained through air separation, to produce ammonia. This process may be used as a “balancing load” to consume excess electricity on the grid and maintain grid stability. The product, ammonia, plays the role of a chemical storage option for excess renewable energy. This excess energy in the form of ammonia can be stored for long periods of time using mature technologies and an existing global infrastructure, and can further be used either as a fuel or a chemical commodity. Ammonia has a higher energy density than hydrogen; it is easier to store and transport than hydrogen, and it is much easier to liquefy than methane, and offers an energy chain with low carbon emissions.The objective of this study is to analyze technical, institutional and economic aspects of power-to-ammonia and the usage of ammonia as a flexible energy carrier.

Health in SIA [social impact assessment]

SIA developed alongside EIA in the early 1970s as a mechanism to consider the social impacts of planned interventions. The early understanding tended to limit the practical application of SIA to the project level, usually within the context of regulatory frameworks, and primarily considered only the direct negative impacts. However, like other types of impact assessment, SIA has evolved over time and has diverged considerably from EIA.

Health in SIA

SummarySocial impact assessment (SIA) developed alongside EIA in the early 1970s as a mechanism to consider the social impacts of planned interventions. The early understanding tended to limit the practical application of SIA to the project level, usually within the context of regulatory frameworks, and primarily considered only the direct negative impacts. However, like other types of impact assessment, SIA has evolved over time and has diverged considerably from EIA. Nowadays, SIA has widened its scope to become a“philosophy about development and democracy”. Ideally SIA considers the pathologies, goals, and processes of development. In this broad understanding, it now focuses on the management of all social issues, intending to bring about a more sustainable and equitable biophysical and human environment.The SIA field defines “social” very broadly, as “anything that affects people and their communities”. Thus,for example, all environmental impacts are also social impacts because people depend on the environment for their livelihoods as well as their physical and spiritual well-being. Social impact concepts include people’s way of life, their culture, community, political systems, environment, health and wellbeing, personal and property rights, and their fears and aspirations.Formerly seen as a regulatory tool required by regulatory agencies but resented by proponents, SIA, for a variety of reasons, is now increasingly being embraced by corporations and used as an internal process for managing social issues. Such a shift towards corporate acceptance, of course, does not guarantee that SIA will always be done properly, or that it is able to adequately influence company operations.Several other shifts have been observed: greater consideration of benefits; moving towards developing and implementing Social Impact Management Plans; communities themselves actively commissioning, or doing, their own SIA studies; SIA playing an important part in ensuring “free, prior and informed consent” and gaining a “sociallicense to operate”.Health issues have a central place in SIA. Many of the social impacts of projects could also be described as health impacts, and all health impacts would be regarded as social impacts in SIA. In SIA, health impacts are considered amongst a wide range of impacts on people and communities. SIA practitioners are supposed to look from an integrated perspective. Arguably, this means that the determinants of health should be addressed when SIA is carried out properly. Nevertheless, SIA guidelines do not typically require a detailed analysis of the origins of, or pathways to, specific health conditions. There is, however, a strong awareness of indirect effects and cumulative effects.In actual practice, the SIA approach used highly depends on the type of policy, plan or project being considered, as well as on the legal and cultural context, on client requirements, and on the commitment of the individual practitioner or consultancy. The SIA case studies considered in this chapter usually discussed the broader determinants of health but did not necessarily recognize them as such. The pathways from social impacts to health, and the linkages between health and social impacts, were not explicitly part of the analysis. Overall, the input of health expertise into SIAs seemed to be lacking. However, given the close connections between the HIA and SIA approaches, more cooperation and crossfertilization between these two types of impact assessment can be expected in the future.

Beroepen in Transitie

In deze publicatie wordt de invloed van digitalisering op drie beroepen (kapitein, wijkverpleegkundige en manager operations ICT) in beeld gebracht aan de hand van drie portretten. De focus ligt op de veranderingen die plaatsvinden op de werkvloer in het werk dat de beroepsbeoefenaars uitvoeren en de kennis en kunde (21st century skills) die noodzakelijk zijn om het werk te kunnen blijven doen. Een aantal belangrijke conclusies zijn dat het werk complexer wordt, meer coördinatie vereist en meer interactie vereist met de omgeving (klant, cliënt, opdrachtgever). Over ICT valt op dat digitalisering niet alleen van invloed is op de aard van het werk, maar ook op de manier en frequentie van communiceren én op de administratieve en regeldruk. Het heeft een zichzelf versterkend effect. Verder is er veel variatie in hoe en waar men leert. Hierbij speelt ook de aard van het werk een rol. Tenslotte wordt het werk interessanter maar stelt het ook hogere eisen omdat er vele ballen ind e lucht moeten worden gehouden. Deze publicatie behoort bij het filmpje maar kunnen los van elkaar beschouwd worden.
