Behaviour, practices and culture constitute a powerful human factor in the energy system; in particular the interactions between technologies, practices and norms lock individuals in to certain patterns of (often inefficient) energy use. Consequently, behaviour change has gained traction amongst policymakers as a key area of intervention given the impact energy-related behaviours have on climate change. Given the increasing emphasis within policy perspectives in the European Union, it is surprising that a gap in understanding of the success factors of behaviour change initiatives remains. This paper addresses this gap by identifying and characterising behaviour change initiatives across five European countries (the UK, Ireland, France, Italy, and Spain). The paper provides insights into the success factors and commonly encountered barriers to behaviour change initiatives. Initiatives are classified into 6 broad categories (community-based interventions; information and awareness based interventions; eco-districts; show-case events; energy switching; and smart-technology focused interventions). The results suggest that there are significant knowledge gaps between what is known to work to engage individuals in behavioural change and what is currently being applied in practice. An over-reliance on education and awareness-raising projects is evident, illustrating that such projects do not sufficiently aim for sustained behavioural changes. A dearth of projects incorporating fiscal measures, regulations or legislation to drive behaviour change reflects reluctance on behalf of decision-makers to engage widely with diverse approaches to foster lifestyle change. This paper contributes understandings of the different models and delivery tools employed to change energy-related behaviours; insights into the critical success factors that underpin best practice and the barriers to action; and a ‘what works in practice’ overview of the meaningful approaches to change behaviour.

Abstract: This special issue of the Journal of Cleaner Production focuses on “Energy for Sustainable Future”. It is designed to mirror the increasing relevance of renewable energy sources and improved efficiency as crucial topics for practitioners in industry, for governmental policy makers, as well as for civic service providers, researchers, and educators. The purpose of this special issue is to serve as a catalyst for dialogue. The global warming related to CO2 emissions, coupled with steeply rising energy prices and the recent global financial institutional melt-down are causing massive societal concerns and give rise to increasing demand for ways to improve societal and individual energy efficiency and for ways to shift increasingly to alternative, low or non-carbon based energy systems. Until recently, industrial energy efficiency improvements have focused on improvements on efficiency rather than on the integration of renewable sources. The aim of this special issue is the identification of policies to support the development and implementation of technologies and management approaches we can employ to make the transition to more sustainable societies. The collection of papers in this special issue provide a foundation for students, researchers, scholars, practitioners and policy makers interested in making sustainable development more than a metaphor. The papers include focus upon ways for: [(a)] Improving industrial process to achieve improvements in energy efficiency. [(b)] Minimising waste disposals and reducing their impact through better management. [(c)] Reducing CO2 emissions by making progress toward lower carbon, renewable energy based systems, [(d)] Improving production of biofuels and hydrogen production systems, facilitated by employing cleaner production and novel LCA tools. [(e)] Improving integration of advanced materials and energy efficient equipment in different industrial sectors. Current and future developments in national and world economies are closely connected to sustainable, efficient and safe usage of raw materials and upon energy based on cleaner production concepts and approaches that are ecologically and economically appropriate for the short and for the long-term future of society. These challenges have received considerable attention in the media and scientific journals over the last several years. The idea of developing a specialised conference focussed upon them was put forward on various occasions. Focus upon them became reality on the 5th and 6th May 2008 in the historic Castle of Veszprém, Hungary, the current premises of the Hungarian Academy of Science which hosted the Workshop. The Workshop was a stimulating event and an overwhelming success, with nearly 100 contributors from Africa, North America, Asia and Europe, representing 28 countries. After a comprehensive selection and thorough reviewing procedure 11 papers were selected for this special issue. [Copyright &y& Elsevier]

Climate change and energy security have emerged as the biggest concerns of the present century. Renewable energy sources are not continuous, dependent upon geographical location as well as climatic conditions, and require a very large land footprint. Future of nuclear energy is also uncertain because of public apprehensions and subsequent government policies. To overcome the issues derailing these two virtually carbon-free energy sources, a new hybrid or integrated nuclear-renewable energy system is being proposed and seen as an attractive option. Such integrated energy systems are conceived as a nuclear power reactor coupled with renewable energy generation and industrial processes that may simultaneously tackle the concerns regarding grid flexibility, climate change, energy security, optimal return on invested capital, and settling public concerns. Apart from highlighting the key challenges associated with nuclear energy and renewable energy sources while operating as an independent power generation system, the present paper delineates the various aspects associated with integrated nuclear-renewable energy systems. It may be speculated that integrating nuclear energy and renewable energy into a single hybrid energy system, coupled through informatics linkages, would enable to overcome the demerits present when they operate individual.

How to ensure success for climate change mitigation policies? For the past decades, local climate action has been amongst the main global priorities. The Covenant of Mayors initiative is a major example of bottom-up climate initiative gathering municipalities of all sizes towards GHG reduction under a harmonised framework. Now, after the end of the first phase of the initiative in 2020, would be the time to assess the impact and effectiveness of the planed actions, based on the results of the monitoring exercise. However, the level and quality of monitoring reported by participating municipalities was not as expected and required an initial deep analysis. This study investigates the reasons behind this low number by comparing statistically the action plans of the 1643 CoM municipalities monitoring their emissions against the 3411 municipalities not doing it. The paper describes how, despite technical and financial barriers, key factors such as the direct involvement of local staff, stakeholders in participatory processes from an early stage, accurate budget allocation, or the development of the plan and deployment of actions as soon as possible, enabling municipalities to track and monitor their progress towards their climate target. • Assessing CoM impact is challenging due to the lack of monitoring/progress reports. • The lack of monitoring is explained by technical and financial barriers. • Direct engagement of local staff and stakeholders is key for successful monitoring. • Barriers and drivers found are a valuable guidance for global climate actors.
