Despite understanding the severity of the climate crisis, global action remains highly insufficient to address this challenge. Buildings are significant contributors to climate change due to their substantial global emissions, but can also contribute to urgent climate solutions. High-performance green buildings (HPGBs) can reduce operational building-level emissions dramatically, and potentially offer other benefits that support building users’ wellbeing and sustainable behaviours. HPGBs can provide useful environments to engage and influence culture and can act as publicly visible symbols of emergent local clean economies. However, a gap remains in knowing how best to support the emergence of citizen-led cultures of sustainability (COS) within green building spaces, an effort that could also help address the noted ‘performance gap’ of green buildings that has been linked to occupant behaviours. With the intention of investigating and supporting a growing citizen-led COS in a green building, this study applied an empowerment-based Photovoice method in the context of the HPGB evolv1, located in Waterloo, Ontario, Canada. Six building users (citizens) took and selected photographs, participated in facilitated group discussions and individual interviews, and contributed toward three public exhibitions based on research findings.Based on thematic analysis, findings suggest building citizens know what a COS means to them, and existing barriers and enablers within/around the evolv1 building toward achieving this. In addition, participants recognized the impact of specific green building features on their own personal sustainability-related values and practices, including the influence of sustainability symbolism within the building environment. Lastly, participants articulated specific recommendations for further promoting and growing a COS at evolv1. Significant themes identified are discussed in relation to and expansion of Cole (2014)’s Teaching Green Building (TGB) Model for Learning, providing preliminary insights into the degree to which evolv1 may or may not presently embody key aspects of a TGB. This study contributes to deepening understandings of how researchers and building citizens can support the emergence of COS within green buildings and related environments, with key takeaways that can be usefully applied to other settings, and theoretical and practical implications. Research findings encourage action toward supporting engaged, citizen-led COS, to advance more sustainable futures.

For the past decades spaceflight has been a driver for technology development in various fields, e.g. generation of electrical power, and computers. Human spaceflight missions, require resources typically scarce (e.g. oxygen) and are usually transferred along with the crew to the respective mission target. Future long-term missions aim beyond Low Earth Orbit (i.e. Moon and Mars), necessitating advances especially in closed-loop life-support systems to guarantee mission autonomy. This requires careful handling of the resources, i.e. minimizing waste and where possible harvesting resources in situ. Similarly, on Earth a sustainable way of life requires careful handling of resources. This paper discusses how both pathways relate to each other and how “settling” Earth sustainably and settling in any space location do not differ in their basic paradigms. It is shown how spaceflight has had an impact on sustainability in the past, which technologies are developed for human spaceflight and how they can be applied on Earth to improve sustainability. Finally, a research infrastructure is presented, which can conduct research on closed-loop technologies, immediately benefiting space and terrestrial applications. This incubator is divided into separate functional modules, which allow testing of technology components. These components can be exchanged to test various permutations of technologies. It is recommended to exploit synergy effects between activities concerning human spaceflight and sustainability by intertwining and coordinating these actions. The technological improvement driven by spaceflight programs can be used to drive sustainability as well.

BackgroundYouth-led movements like #FridaysforFuture and the school strikes for climate (henceforth referred to as the climate strikes) are leading calls for action on climate change worldwide. This paper reports on a thematic analysis of protest signs, and interviews with young climate strikers, at a climate strike in Manchester, UK, in 2019.ResultsThis paper explores the ways in which dominant, adult-centred frameworks for conceptualizing young people’s environmental activism tend to obscure the complexities of the climate strike movement. In contrast, this study examines the complex political activism of climate strikers as a ‘subaltern group’, who take political action in a wider context of intersecting categories of oppression and marginalization – including youth as a category of marginalization – and in the historical context of environmental racism, the enduring legacies of colonialism, and global inequality during contemporary capitalism.ConclusionsThe article develops a theoretical model for future research, based on a model of two constraining frames that limit analysis of the climate strikes in particular and young people’s environmental activism in general. This paper contributes to a step change in methods for the study of this remarkable movement in a global context.

The Green Economy is an alternative vision for growth and development; one that can generate economic development and improvements in people’s lives in ways consistent with advancing also environmental and social well-being. One significant component of a green economy strategy is to promote the development and adoption of sustainable technologies. The overall objective of this article is to discuss a number of challenges encountered when pursuing sustainable technological change, and that need to be properly understood by policy makers and professionals at different levels in society. We also identify some avenues for future research. The discussions center on five challenges: (a) dealing with diffuse – and ever more global – environmental risks; (b) achieving radical and not just incremental sustainable technological change; (c) green capitalism and the uncertain business-as-usual scenario; (d) the role of the state and designing appropriate policy mixes; and (e) dealing with distributional concerns and impacts. The article argues that sustainable technological change will require a re-assessment of the roles of the private industry and the state, respectively, and that future research should increasingly address the challenges of identifying and implementing novel policy instrument combinations in various institutional contexts.

Over the last 60 years we have modified our behavior to make use of new synthetic material produced from fossil fuels. We have incorporated it into almost every facet of our lives making us more comfortable. The production of plastic material has grown at an alarming rate and huge volumes of non-biodegradable waste now litters the surface of the planet creating a major global problem. To reverse this problem, we need to consider both obvious and novel behavior change and product development. While we are beginning to remove plastic items from the environment, we do have the responsibility to reduce the amount of new plastic material entering the waste stream. In order to achieve this, it is necessary to explore all options relating to the way we design, produce and consume products and determine what acceptable waste is. This article collection is concerned with addressing the problem by exploring a variety of topics as diverse as the history of plastic material use, behavior change, and the development of new, environmentally friendly products and their impact on the environment. The following essay outlines a few ideas that do require further scientific exploration so we can begin the process of weaning society off its current dependence on plastic products.

BackgroundThe United Nations’ Sustainable Development Goals remind us of the urgent need for every business to operate in ways that are good for planet and people. Manufacturing is a critical sector to address, where industry is compelled to rethink the acts of sourcing, producing, consuming and handling goods and their subsequent ‘waste’ components. Over the last decade in particular, lean and green thinking has emerged as a desirable strategy to improve efficiency and environmental outcomes towards sustainable business practices that meet circular economy objectives. However, moving beyond ad hoc and champion-based take-up by organisations with deep pockets, there is generally a lack of momentum towards mainstreaming such lean and green focused operations in the many small and medium-sized enterprises (SMEs) internationally. This research used case study analysis within the manufacturing sector in Queensland, Australia, to investigate how SMEs could readily engage in lean and green processes to achieve sustainable business practice with regard to the ‘3Ps’ of the triple bottom line (i.e. Planet, Profit and People). ‘Natural resource-based view theory’ and ‘Institutional theory’ were used to develop a conceptual framework to explain the findings.ResultsThe paper describes the lean and green practices observed in the SMEs, drivers for implementation, and the perceived benefits within the realm of sustainable business practice. Building on case study findings, the authors provide the first 3P Model for lean and green strategy, presenting four steps that SMEs can follow, including a 3P matrix of tools to selectively engage with lean and green actions towards sustainable business practice. This model guides SMEs to use the best tools and processes given their circumstances and aspirations.ConclusionsThe model has the immediate benefit of focusing SME time and resources towards circular economy enquiry, reducing uncertainty and enabling forward-planning. The findings provide practical guidelines to enable SMEs to achieve sustainable business practice while appreciating the ‘triple bottom line’ approach. The findings also have immediate policy and governance implications within the public and private sector, providing guidance on integrating lean and green thinking to advance from doing ‘business as usual’.

Scientific knowledge is key to climate mitigation governance. However, effective exchange between science and policy is challenging. Science-policy theory suggests collaboration, stakeholder participation and iterative communication as key principles for improving the science-policy interface. The Horizon 2020 project “Coordination and Assessment of Research and Innovation in Support of climate Mitigation Actions” (CARISMA) attempted to implement these principles. To help other projects learn from CARISMA’s experiences, this Guideline article critically discusses how the CARISMA project fared. CARISMA’s activities included stakeholder engagement through feedback loops, interviews with Advisory Board members, and an information platform. Experiences were discussed in a workshop with science-policy practitioners. Theory and workshop participants’ insights led to the identification of seven practical directions towards a more effective exchange between science and policy, aimed at policymakers, funding agencies and researchers: 1) Know the researcher’s role; 2) Work with policy dynamics; 3) Use alternative communication means; 4) Allow for flexibility in projects’ deliverables and milestones; 5) Be realistic about the possibility of stakeholder engagement; 6) Adjust funding criteria; 7) Invest in stable knowledge infrastructures.
