Meeting climate change targets to limit global warming to 2°C requires rapid and large reductions in demand for products that most contribute to greenhouse gas (GHG) emissions. These include production of bulk materials (e.g. steel and cement), energy supply (e.g. fossil fuels) and animal source foods (particularly ruminants and their products). Effective strategies to meet these targets require transformative changes in supply as well as demand, involving changes in economic, political and legal systems at local, national and international levels, building on evidence from many disciplines. This paper outlines contributions from behavioural science in reducing demand. Grounded in dual-process models of human behaviour (involving non-conscious and conscious processes) this paper considers first why interventions aimed at changing population values towards the environment are usually insufficient or unnecessary for reducing demand although they may be important in increasing public acceptability of policies that could reduce demand. It then outlines two sets of evidence from behavioural science towards effective systems-based strategies, to identify interventions likely to be effective at: (i) reducing demand for products that contribute most to GHG emissions, mainly targeting non-conscious processes and (ii) increasing public acceptability for policy changes to enable these interventions, targeting conscious processes. This article is part of the themed issue ‘Material demand reduction’.

PurposeDespite awareness of climate change for over 3 decades, per capita energy and water consumption increase and environmental impacts grow. The built environment contributes around 40% of total global greenhouse gas (GHG) emissions; action is vital. Whilst building code standards have increased, rating tools and technology to reduce energy and water consumption are developed; environmental impact grows because of human behaviour. In the tertiary education sector, student accommodation constitutes a large part of the property portfolio, contributing significant amounts of GHG emissions and environmental impact. Property Managers can educate and install systems and technologies to improve behaviour if they understand it.Design/methodology/approachThis exploratory study used a questionnaire survey to explore how student's worldviews vary and the possible limitations to behaviour in respect of climate change. In total, 71 responses from international university students living in residential accommodation on campuses in Stockholm were analysed.FindingsThe results show different perceptions about the environment and actions that are needed, and this leads to different behaviours. Limited knowledge and inability to relate environmental consequences to one's own actions, effective communication and risk averse behaviour, are critical in mitigating climate change. A deeper understanding of participants worldviews and the different resulting behaviours was achieved.Research limitations/implicationsThis pilot study involved a small number of participants and future studies should expand participant numbers, including those with more varied backgrounds, education levels and age groups.Practical implicationsIf property managers gain a deeper understanding the different behaviours of their residents, they can develop effective strategies to facilitate action that will lower the environment impact and GHG emissions of student accommodation.Originality/valueThe knowledge gained about environmental attitudes and human behaviour can help property and facility managers, policy makers and regulators to develop more effective strategies to deliver improved sustainability outcomes.

Limited fuel resources and the huge negative impact on the environment from using fossil fuels have led to an urgency to utilize the most energy efficient solutions for public transportation. Environmentally sustainable solutions can deliver the same benefits of traditional systems, but without the negative impacts. The Bus Rapid Transit Project of Amman (Amman BRT) is used as a case study. Proposed measures include using electric buses instead of diesel ones, and installing elevated photovoltaic systems above buses parking and routes, in addition to using LED street lighting. The feasibility study of applying the proposed measures on the Amman BRT project showed that only 7.1 years is needed to payback the incremental investment throughout this transformation. Capital expenditure (CAPEX) is higher than the baseline buses, while operational expenditure (OPEX) is much lower, resulting in a 32% lower total cost of ownership (TCO). In addition, greenhouse gas (GHG) emissions are reduced by 27,203.68 metric ton of CO2 per year and 408,055.26 metric tons for the 15-year lifetime of the project.

Dual Process Model

This article presents an extended dual-process model of entertainment effects on political information processing and engagement. We suggest that entertainment consumption can either be driven by hedonic, escapist motivations that are associated with a superficial mode of information processing, or by eudaimonic, truth-seeking motivations that prompt more elaborate forms of information processing. This framework offers substantial extensions to existing dual-process models of entertainment by conceptualizing the effects of entertainment on active and reflective forms of information seeking, knowledge acquisition and political participation.

The food industry is responsible for supplying the food demand of the ever-increasing global population. The food chain is one of the major contributors to greenhouse gas (GHG) emissions, and global food waste accounts for one-third of produced food. A solution to this problem is preserving crops, vegetables, and fruits with the help of an ancient method of sun drying. For drying agricultural and marine products, several types of dryers are also being developed. However, they require a large amount of energy supplied conventionally from pollutant energy sources. The environmental concerns and depletion risks of fossil fuels persuade researchers and developers to seek alternative solutions. To perform drying applications, sustainable solar power may be effective because it is highly accessible in most regions of the world. Greenhouse dryers (GHDs) are simple facilities that can provide large capacities for drying agricultural products. This study reviews the integration of GHDs with different solar technologies, including photovoltaic (PV), photovoltaic-thermal (PVT), and solar thermal collectors. Additionally, the integration of solar-assisted greenhouse dryers (SGHDs) with heat pumps and thermal energy storage (TES) units, as well as their hybrid configuration considering integration with other renewable energy sources, is investigated to improve their thermal performance. In this regard, this review presents and discusses the most recent advances in this field. Additionally, the economic analysis of SGHDs is presented as a key factor to make these sustainable facilities commercially available.

The present work reviews the role of biogas as advanced biofuel in the renewable energy system, summarizing the main raw materials used for biogas production and the most common technologies for biogas upgrading and delving into emerging biological methanation processes. In addition, it provides a description of current European legislative framework and the potential biomethane business models as well as the main biogas production issues to be addressed to fully deploy these upgrading technologies. Biomethane could be competitive due to negative or zero waste feedstock prices, and competitive to fossil fuels in the transport sector and power generation if upgrading technologies become cheaper and environmentally sustainable.
