Heating buildings contributes to approximately 36 % of Europe's energy demand and several EU member states have adopted mandatory energy labels to improve energy efficiency by promoting home weatherization investments. This paper focuses on the perception of the energy label for residential buildings in the Netherlands and the role of different frames (egoistic, biospheric and social norms and neutral frames) in motivating adoption of energy labels for housing. We used a behavioral email experiment and an online survey to investigate these motivational factors. We find that biospheric frames are weaker than the other three motivational frames in terms of engaging interest in the energy label, but that the biospheric frame results in higher willingness to pay (WTP) for the energy label. We also find that age (rather than income) correlates with higher WTP for home energy labels.

This study reviews the scientific literature for business models contributing to sustainable plastic management and suggests avenues for future research. We define sustainable plastic management (SPM) as any technique along the waste hierarchy seeking to minimize the environmental damage of plastic material. Limited cases were found during the literature review, whereas many more SPM business models exist in practice, signaling a research gap. Forty-four scientifically documented business models were identified and analyzed on the basis of business model component, sustainability, level of waste hierarchy and sustainable business model archetype. Our results suggest that business models focus on recycling and creating value from waste, as well as the development of bioplastic. Few cases qualified as triple bottom line businesses, as many reported environmental and economic, but not social, benefits. Circular economy business models were found in a quarter of all cases. Finally, we present a synthesis of the barriers and opportunities for sustainable plastic management by the private sector. Drivers include maintaining competitive advantage, accessing green customers, collaboration with stakeholders, and achieving efficiency improvements. Barriers frequently mentioned were high costs, complexity of new systems, supply chain lock-in and low customer buy-in. Further research should expand the scale of SPM research, identify the enabling conditions for sustainable plastic management, and determine environmental impact.

Modern fuels are an important enabler of social and economic development. Still, over 2 billion people rely on traditional biomass for their daily energy needs. To overcome the negative effects of traditional energy on human health and the environment and to enhance the livelihood conditions of the poor, a transition towards cleaner and more efficient forms of energy is needed. Understanding household fuel choice and fuel switching behaviour is of vital importance in search for policies to support such a transition process. This paper adds to the existing energy transition literature in two ways. First, we provide a novel conceptual framework to analyze the decision environment underlying energy and fuel choices. Second, we apply this framework in a meta-analysis of existing choice models investigating energy switching and stacking behaviour in urban and rural areas in developing countries. The meta-analysis shows that socio-economic household characteristics appear to receive most attention so far in identifying groups of fuel users, while relatively little information is available on the impact of the external decision context on household energy choices. © 2012 Elsevier Ltd.

The main objective of this paper is to provide additional empirical evidence of what explains respondent uncertainty in contingent valuation (CV) and how this in turn affects stated willingness to pay (WTP). Air travelers asked to pay a carbon travel tax to offset carbon emissions from flying were asked how likely it is that they will actually pay if the tax is voluntary. When changing the market compliance imperative from a mandatory carbon tax to a voluntary contribution, a third of all air travelers consider it unlikely they will actually pay their stated WTP amount. An ordered probit estimation approach is applied to identify the sources of respondent uncertainty. Besides the bid price, respondent sense of responsibility and belief in the effectiveness of the voluntary carbon market are among the main reasons for the experienced uncertainty. © 2008 Elsevier B.V.

This paper explores the representation of goods and services from the subsurface, as defined by the concept of geosystem services, in contemporary ecosystems literature. A framework is defined consistent with and complementary to the categorisation defined under CICES. Following the Campbell Collaboration protocol, a systematic literature review is conducted on the representation of subsurface-related goods and services in ecosystem services research. The review shows that, in the period between 2000 and 2016, for every publication on subsurface services 140 articles on ecosystem services have been published. The results further indicate that valuation and governance studies on geosystem services are scarce. This gap stems from the exclusion of a number of abiotic goods and services from the classification as well as a lack of attention from the current scientific community to this topic. Studies to date have been performed in a limited number of English-speaking countries by researchers with backgrounds in ecology, biology, earth sciences and mining engineering. The underrepresentation of geosystem services in the scientific literature negatively impacts integrated decision making in spatial planning, environmental policy making and long term ecosystem management.

The determinants of farmers’ decisions to reduce greenhouse gas (GHG) emissions are currently not well understood. This study takes several new angles in investigating farmers’ climate change mitigation behaviour. Based on two identical surveys among representative samples of Dutch farmers, this study examines the underlying determinants and motivating factors for three different types of climate change mitigation measures on farms: energy saving, the production of renewable energy and reduction of emissions of methane and nitrous oxide (non-CO2 emissions). Furthermore, the study explores whether farmers’ awareness and behaviour has been influenced by a communication campaign carried out by the government of the Netherlands between 2012 and 2015. Four major conclusions emerge. Firstly, the analyses demonstrate that accounting for the cost-effectiveness and technology readiness level (TRL) of different types of climate change mitigation measures provides for a better understanding of the factors that motivate farmers to adopt these measures. Secondly, neither the willingness to take GHG reduction measures nor knowledge on GHG emissions are consistent motivating factors for energy-related measures. Thirdly, it seems that external factors, such as economic hardship, dominate the overall environmental awareness of farmers. Fourthly, the farmer’s propensity to innovate proved to be the strongest and most consistent predictor of both the willingness and the actual adoption of climate change mitigation technologies. Therefore, focusing on making farmers more open to change and general innovation in campaigns in the agricultural sector might be more effective than campaigns focusing specifically on climate change mitigation.
