Annual Review of Environment and Resources - Early Publication

Developing transformative pathways for industry's compliance with international climate targets requires model-based insights into how supply- and demand-side measures affect industry, material cycles, global supply chains, socioeconomic activities, and service provisioning that support societal well-being. We review the recent literature modeling the industrial system in low energy and material demand futures, which mitigates environmental impacts without relying on risky future negative emissions and technological fixes. We identify 77 innovative studies drawing on nine distinct industry modeling traditions. We critically assess system definitions and scopes, biophysical and thermodynamic consistency, granularity and heterogeneity, and operationalization of demand and service provisioning. We find that combined supply- and demand-side measures could reduce current economy-wide material use by 56%, energy use by 40% to 60%, and greenhouse gas emissions by 70% to net zero. We call for strengthened interdisciplinary collaborations between industry modeling traditions and demand-side research to produce more insightful scenarios, and we discuss challenges and recommendations for this emerging field.

Healthy soils contribute to a wide range of ecosystem services and virtually all of the UN Sustainable Development Goals, but most of the world's soil resources are in only fair, poor, or very poor condition, and conditions are getting worse in more cases than they are improving. A total of 33% of all soils are moderately to highly degraded as a result of erosion, loss of organic matter, poor nutrient balance, salinization and alkalinization, contamination, acidification, loss of biodiversity, sealing, compaction, and poor water status. Best management practices are available to limit or mitigate threats to soil health, and many of them mitigate multiple soil threats. In many regions of the world, policies or initiatives to protect or enhance the status of soils are in place, and they need to be strengthened and enforced. The Food and Agriculture Organisation will publish its second comprehensive assessment of the status of the world's soils in 2025, and this review provides an interim update on world soil status and offers an accessible overview of the topic.

Facing the world's ecological, economic, and social challenges requires us to connect the concepts of justice, sustainability, and transitions. Bridging and discussing heterogeneous fields, we argue that these concepts need to complement each other, and we present just sustainability transitions (JUSTRAs) to do so. To define JUSTRAs, we review the state-of-the-art literature, focusing on the understanding of these three concepts and their pairings in various disciplinary fields and empirical settings (e.g., environmental justice, just transitions, sustainability transitions, energy justice, food justice, urban justice). We center marginalized voices to highlight the processes of radical transformative change that JUSTRAs seek. We offer three analytical lenses that further the understanding of JUSTRAs: politics, power, and prefiguration. We argue that these complementary lenses are necessary to remake the world in both critical and pragmatic ways. Finally, we present a research agenda on JUSTRAs, foregrounding three complementary modes of inquiry: analyzing, critiquing, designing.

Conservation of biodiversity is above all else an exercise in human persuasion. Human behavior drives all substantive threats to biodiversity; therefore, influencing it is the only path to mitigating the current extinction crisis. We review the literature across three different axes to highlight current evidence on influencing human behavior for conservation. First, we look at behavioral interventions to mitigate different threats, from pollution and climate change to invasive species and human disturbance. Next, we examine interventions focused on different stakeholders, from voters, investors, and environmental managers to consumers, producers, and extractors. Finally, we review delivery channels, ranging from mass and social media to interventions involving changes to the physical environment or carried out in person. We highlight key gaps, including the lack of scale and robust impact evaluation of most interventions, and the need to prioritize behaviors, overcome the reproducibility crisis, and deal with inequality when designing and implementing behavior change interventions.

Globally, the production of concrete is responsible for 5% to 8% of anthropogenic CO2 emissions. Cement, a primary ingredient in concrete, forms a glue that holds concrete together when combined with water. Cement embodies approximately 90% of the greenhouse gas emissions associated with concrete production, and decarbonization methods focus primarily on cement production. But mitigation strategies can accrue throughout the concrete life cycle. Decarbonization strategies in cement manufacture, use, and disposal can be rapidly implemented to address the global challenge of equitably meeting societal needs and climate goals. This review describes (a) the development of our reliance on cement and concrete and the consequent environmental impacts, (b) pathways to decarbonization throughout the concrete value chain, and (c) alternative resources that can be leveraged to further reduce emissions while meeting global demands. We close by highlighting a research agenda to mitigate the climate damages from our continued dependence on cement.

Covering two-thirds of the ocean and half of the planet's surface, the high seas are increasingly the focus of commercial activity and conservation ambitions. Contrary to narratives of a lawless frontier, they are governed by a dense network of sectoral institutions for shipping, fisheries, and other industries, although these collectively deal with conservation and sustainable use of biodiversity in a fragmented and uneven manner. These gaps were the subject of nearly 20 years of negotiation, resulting in the adoption of the Agreement on Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction in June 2023. The Agreement was designed to address access and benefit sharing associated with marine genetic resources; the establishment of area-based management tools such as marine protected areas, Environmental Impact Assessments, and capacity building; and the transfer of marine technology. Achieving coherence across public and private governance mechanisms will be a significant challenge as human activity increases on the high seas, but it is key to achieving ocean sustainability goals.

This review examines the promises and pitfalls of multistakeholder partnerships (MSPs) for sustainable development. We take stock of the literature on the creation, effectiveness, and legitimacy of MSPs and focus on recent research on MSPs committed to achieving the 2030 Agenda and United Nations Sustainable Development Goals (SDGs). The 2030 Agenda conceives of MSPs as vehicles to achieve large-scale sustainability transformations. Yet, research on MSPs under earlier sustainable development initiatives found that they had limited effectiveness and significant legitimacy deficits. We show that recent research on SDG partnerships suggests they reproduce many of the shortcomings of their predecessors and so are unlikely to foster synergies and minimize trade-offs between areas of sustainable development to deliver transformations on a global scale. We also examine recent research on the prospects of governing MSPs to enhance accountability and ensure better institutional designs for achieving transformations, highlighting challenges arising from international political contestation.

We are already experiencing the rapid pace of environmental change in the Anthropocene, necessitating the development of new tools and techniques for measuring changes in ecosystem dynamics. Sentinel species, from birds to invertebrates, have been used to provide insights into ecosystem function, as leading indicators of risk to human health and as harbingers of future change, with implications for ecosystem structure and function. Here, we offer an update to previous research identifying marine top predators as indicators of ecosystem change and examine terrestrial sentinels and the latest research on sentinels of pollution and human health. Using ecosystem sentinels enables rapid response and adaptation to ecosystem variability and environmental change in part because they may be easier to observe and in part because they may serve as leading indicators of ecosystem change. While there may not be a given taxon that is best suited as sentinels, we highlight how to select the most effective sentinels, including examples of when sentinel species have been incorporated into management. Choosing a suite of appropriate sentinels will both give insight into ecosystem processes and can help manage changing ecosystems into the future.

Environmental governance occurs through and is shaped by communication. We propose a typology of public communication, classifying it by directionality (one-way or two-way) and objective (informational or operational). We then review how communication types influence individuals’ cognitive frames, values, and environmental behaviors. Though one-way communication is common, its impact is often limited to influencing cognitive frames. Research on two-way informational communication demonstrates a greater ability to align cognitive frames and values among individuals, and research on two-way operational communication demonstrates the greatest impact on conceptual frames, values, and environmental behaviors. Factors that affect the impact of communication include the medium through which it occurs, trust, timing, and social-material context. Among these, our review considers new directions in public communication research that focus on the role of digital platforms, misinformation, and disinformation. We conclude by synthesizing research on deliberative communication, a case of communication among citizens guided by democratic ideals.
