After the Paris Agreement that put stronger emphasis on the development of climate change adaptation policies and on the definition of financing mechanisms, there is a patent need to track whether actual planning efforts are proving sufficient. This entails the development of assessment methods and metrics as plans are drafted and actions implemented. To this end, this paper explores the concept of credibility as a critical issue in climate policy and develops an Adaptation Policy Credibility (APC) conceptual and operational assessment framework for helping to allocate public funding and private investments, and for implementing and catalysing climate policy. Through a pilot testing in four early-adopting cities (Copenhagen, Durban, Quito and Vancouver), a clear potential for large-n tracking and assessment exercises of local climate adaptation plans is envisaged. The APC approach might also be useful to guide individual cities that aim to improve their adaptation planning and policy-making processes.

Informational failures frequently lead consumers to make non-optimal energy-efficient purchasing decisions. Energy efficiency labels seek to influence consumer behaviour at the point of sale by reducing informational failures regarding energy efficiency. However, several informational and behavioural factors contribute to the energy efficiency gap and could render label-oriented policies useless. The purchasing decision model of Allcott and Greenstone (The Journal of Economic Perspectives, 26, 3–28, 2012) is used here to explore the different factors that influence purchasing decisions and understand (i) the importance of energy consumption compared to other attributes; (ii) how consumers weight energy savings and (iii) what other benefits and costs influence the purchase of energy-efficient goods. The analysis reported here is based on qualitative research methods and is conducted in the household and service sectors (the accommodation sector and private service companies), for appliances, heating and cooling systems and cars in Spain. Results show that (i) there is still an informational gap regarding energy labels and (ii) bounded rationality and end-user behaviour are important limiting factors for the purchase of energy-efficient goods in Spain.
