Many citizens experience ambivalence – having simultaneously positive and negative evaluations – about changing their behaviour towards a more environmentally friendly lifestyle. Based on 36 studies, this study identifies and synthesises the current evidence on how ambivalence impacts environmental behaviours. In most studies, ambivalence is shown to be directly and negatively associated with environmental behaviours, i.e., higher levels of ambivalence are linked to lower levels of environmentally friendly and unfriendly behaviours. This applies to both types of ambivalence: objective (OA) and subjective (SA). Mediator analyses show, in line with the theory, that SA, not OA, drives behavioural change. In addition, results indicate that ambivalence moderates the relationship between independent–dependent variables mainly negatively, for example, by weakening attitude–behaviour relationships. This review shows the potential of ambivalence to facilitate behaviour change: SA about environmentally friendly behaviour can hinder, whereas SA about environmentally unfriendly behaviour can motivate, behaviour change. In addition, this review highlights some significant knowledge gaps in this body of research. A lack of validated standardised measurements of ambivalence makes it challenging to compare studies and reach conclusions about underlying theoretical constructs. Methods, research designs, and theoretical underpinnings need improvement to fully understand ambivalence and progress towards the transition of environmentally friendly behaviours.

from the article: Abstract Based on a review of recent literature, this paper addresses the question of how urban planners can steer urban environmental quality, given the fact that it is multidimensional in character, is assessed largely in subjective terms and varies across time. The paper explores three questions that are at the core of planning and designing cities: ‘quality of what?’, ‘quality for whom?’ and ‘quality at what time?’ and illustrates the dilemmas that urban planners face in answering these questions. The three questions provide a novel framework that offers urban planners perspectives for action in finding their way out of the dilemmas identified. Rather than further detailing the exact nature of urban quality, these perspectives call for an approach to urban planning that is integrated, participative and adaptive. ; ; sustainable urban development; trade-offs; quality dimensions
This article reflects on the workshop Bridging the KAP-gap in global education, which was part of the DEEEP-conference Global Justice through Global Citizenship. The objective of the workshop was, to learn about strategies to bridge the KAP (Knowledge, Attitude, Practice) -gap and to gain ideas how to apply these strategies to participants’ own practices. The workshop turned into a slightly different direction and raised some fundamental questions: What could one expect of global education? Which others factors influence learners’ behaviour? To which manner does global education aim to change behaviour? Should global education aim to change behaviour? This article summarizes the outcomes of an evaluation which was done amongst alumni-students of the minor programme Global Development Issues of Fontys University of Applied Sciences and the main issues that were discussed during the workshop, also based on the integrated model of behavioural prediction. The article ends with some lessons learned, especially for the curriculumowners of the minor programme, who organised this workshop.

Due to the existing pressure for a more rational use of the water, many public managers and industries have to re-think/adapt their processes towards a more circular approach. Such pressure is even more critical in the Rio Doce region, Minas Gerais, due to the large environmental accident occurred in 2015. Cenibra (pulp mill) is an example of such industries due to the fact that it is situated in the river basin and that it has a water demanding process. The current proposal is meant as an academic and engineering study to propose possible solutions to decrease the total water consumption of the mill and, thus, decrease the total stress on the Rio Doce basin. The work will be divided in three working packages, namely: (i) evaluation (modelling) of the mill process and water balance (ii) application and operation of a pilot scale wastewater treatment plant (iii) analysis of the impacts caused by the improvement of the process. The second work package will also be conducted (in parallel) with a lab scale setup in The Netherlands to allow fast adjustments and broaden evaluation of the setup/process performance. The actions will focus on reducing the mill total water consumption in 20%.
A fast growing percentage (currently 75% ) of the EU population lives in urban areas, using 70% of available energy resources. In the global competition for talent, growth and investments, quality of city life and the attractiveness of cities as environments for learning, innovation, doing business and job creation, are now the key parameters for success. Therefore cities need to provide solutions to significantly increase their overall energy and resource efficiency through actions addressing the building stock, energy systems, mobility, and air quality.The European Energy Union of 2015 aims to ensure secure, affordable and climate-friendly energy for EU citizens and businesses among others, by bringing new technologies and renewed infrastructure to cut household bills, create jobs and boost growth, for achieving a sustainable, low carbon and environmentally friendly economy, putting Europe at the forefront of renewable energy production and winning the fight against global warming.However, the retail market is not functioning properly. Many household consumers have too little choices of energy suppliers and too little control over their energy costs. An unacceptably high percentage of European households cannot afford to pay their energy bills. Energy infrastructure is ageing and is not adjusted to the increased production from renewables. As a consequence there is still a need to attract investments, with the current market design and national policies not setting the right incentives and providing insufficient predictability for potential investors. With an increasing share of renewable energy sources in the coming decades, the generation of electricity/energy will change drastically from present-day centralized production by gigawatt fossil-fueled plants towards decentralized generation, in cities mostly by local household and district level RES (e.g PV, wind turbines) systems operating in the level of micro-grids. With the intermittent nature of renewable energy, grid stress is a challenge. Therefore there is a need for more flexibility in the energy system. Technology can be of great help in linking resource efficiency and flexibility in energy supply and demand with innovative, inclusive and more efficient services for citizens and businesses. To realize the European targets for further growth of renewable energy in the energy market, and to exploit both on a European and global level the expected technological opportunities in a sustainable manner, city planners, administrators, universities, entrepreneurs, citizens, and all other relevant stakeholders, need to work together and be the key moving wheel of future EU cities development.Our SolutionIn the light of such a transiting environment, the need for strategies that help cities to smartly integrate technological solutions becomes more and more apparent. Given this condition and the fact that cities can act as large-scale demonstrators of integrated solutions, and want to contribute to the socially inclusive energy and mobility transition, IRIS offers an excellent opportunity to demonstrate and replicate the cities’ great potential.

Climate change and the depletion of resources in the world are widely recognized as the greatest societal challenges. The building sector is responsible for 40% of the raw material consumption globally. The emissions related to construction materials are anticipated to double by 2050, if no new technologies are adopted (EC, 2021). Based on the environmental cost indicator, isolation has the second largest (after concrete) impact to the environment. In Mythic - Myterials for THermal Insulation in Construction goal is to develop (in co-creation with the work field) the best available mycelium biocomposite, which can be used as a circular, biodegradable insulation material for construction in the building sector. In recent research projects partners concluded that Mycelium biocomposites have a high potential to replace traditional fossil-based isolation materials, but further research on the thermal insulation and moisture absorption is needed to convince the construction market. In the project various partners will cooperate, both from the production side of mycelium composites, as well as from the application side. Some partners originate from previous projects, but others contacted Centre of Expertise for the Biobased Economy (CoEBBE) to build further on the existing network. There are several SME’s from the Netherlands, but also from abroad (Nylausn from Iceland, Mogu Srl from Italy and Corstyrene form France), as well as Branche organizations and knowledge institutes. Avans works together with HZ in CoEBBE and for the microbiological knowledge we cooperate with the University of Utrecht. For the market research CoEBBE cooperates with the lectorate New Marketing within Avans, focussing on sustainability via biomimicry. Mycelium composites and natural products for the building industry is the theme that binds all partners.
