Inequality in PM2.5 Exposure and Health burden attributable in China
Abstract PM2.5 pollution poses significant health risks in China, with over one million premature deaths annually. Although major air quality regulations were enacted in 2013 and substantial progress has been made, the equitable distribution of health benefits remains uncertain. This study uses…

Systemic approaches for the protection of our oceans and marine environments
Abstract Protecting our oceans and advancing a sustainable blue economy require in-depth understanding of marine systems, driven by robust ocean observation, monitoring and valuation. Yet collecting reliable data remains time- and resource-intensive. This data is vital for scientists, emergency…

Navigating the overlap of climate-induced and conflict-induced displacement: perspectives from humanitarian practitioners in the Philippines
Abstract Disasters, conflict, and climate change increasingly intersect, forcing communities to flee and trapping them in cycles of displacement. Yet, humanitarian responses remain fragmented, often addressing displacement crises in isolation. This study explores how humanitarian practitioners in…

The importance of radical transparency for responsible carbon dioxide removal
Carbon removal is a strongly debated component of societal efforts to address anthropogenic climate disruption, in part because efforts to scale carbon removal could delay or substitute for efforts aimed at mitigating anthropogenic greenhouse gas emissions. Although there is no single solution to…

Charting our forest future: national supply curves for forest-based CO₂ mitigation
Abstract Forests currently store more carbon in their vegetation and soil than all of the carbon in earth’s atmosphere. But how much additional CO₂ can be removed and sequestered by forests in the future, and at what cost? This study examines the potential and costs of forest-based mitigation in…

Advancing transformational leadership for climate action
Abstract This perspective paper explores how transdisciplinary research can advance leadership for climate action. Based on a two-year collaborative inquiry, we argue that dominant, individual-centric models—typically rooted in charisma, hierarchy, and expertise—are inadequate for addressing crises…

Could lessons from medical research ethics inform better conversations and governance for climate engineering research
Conversations about climate engineering are difficult to have in many spaces. While public debate deserves exploration, we focus on the difficulties scientific discussions around climate engineering face. For inspiration on how to improve this contested space we turn specifically to the history of…

Understanding fluctuating climate change risk perceptions through the lens of trust: a study of Great Barrier Reef region residents
Abstract Public perceptions of climate change risks are fundamental to public support for climate action. From a decade of surveying residents in the Great Barrier Reef region (2013–2023; n = 9920), we found that climate risk perceptions have fluctuated markedly, with shifts mainly occurring at the…

From data to decarbonization: the digital economy’s role in reducing carbon emissions intensity and advancing environmental justice
Abstract Using panel data from 286 prefecture-level cities in China, this study constructs a city-level digital economy index and examines its impact on carbon emissions intensity and related mechanisms. Theoretically, the digital economy can reduce carbon emissions intensity by increasing energy…

Education capacity building as a foundation for climate resilient development in SIDS
Climate resilient development (CRD) offers small island developing states (SIDS) a chance to integrate climate adaptation and mitigation into development decisions that benefit civil society. Yet, present climate actions lack education capacity building across formal curriculum development…

Delays in nationally determined contributions often reflect credibility efforts and not weakening ambition
This Comment examines why many countries delayed submitting updated Nationally Determined Contributions after the 2023 Global Stocktake. We argue that postponements often reflect efforts to enhance credibility and align pledges with domestic policy, rather than a lack of ambition. Based on…

Stakeholder preferences and perceived effectiveness of coastal adaptation measures in Seychelles
Abstract Effective coastal adaptation to sea-level rise (SLR) is a complex and urgent challenge, especially for Small Island Developing States (SIDS), where responses are shaped by social, ecological, and governance dynamics. Here, we investigate how stakeholders in Seychelles perceive the…

Assessing renewable wind and solar energy yield with gridded climate datasets
Abstract Gridded meteorological datasets—reanalyses and climate simulations—are increasingly central to renewable energy yield assessments, offering complete, physically consistent atmospheric variables required to transform resource data into power output. This review delivers the first holistic…

Red flags in green promises: a framework for identifying greenwashing risk in corporate climate pledges
Abstract As corporate net-zero pledges multiply, concerns about their credibility and potential for greenwashing are rising. This study is the first to develop a framework specifically tailored to assessing greenwashing in climate and net-zero pledges, combining disclosures, implementation plans…

Mathematical and Ethical Considerations in Economics Modelling
Abstract We consider the mathematical properties of economic models concerned with value maximisation, including integrated assessment models. We illustrate how the outcomes that result from maximising value subject to convergence to a steady state in the long run may be very different from the…

Justice for Animals in Climate Change Integrated Assessment Models
Abstract Integrated assessment models (IAMs) exclude individual non-human animal welfare, despite clear evidence that climate change will harm billions of animals through habitat loss, extreme weather, and ecosystem disruption. We argue that this is a significant moral oversight. Further…

Narrative and quantitative analysis of democratic principles in the Shared Socioeconomic Pathways
Abstract Although climate action is highly intertwined with governance structures, climate policy modelling science has been argued to insufficiently reflect political processes. We analyse the evolution of democratic governance embedded in the Shared Socioeconomic Pathways (SSPs) that are heavily…

A blockchain-based carbon registry platform for credible climate action in transportation
Abstract Achieving global climate commitments requires credible climate action grounded in rigorous measurement, reporting, and verification (MRV). However, most carbon registries rely on loosely organized MRV processes that are frequently criticized for inadequate verification, double counting…

Empirically assessing corporate adaptation and resilience disclosure using AI
Abstract The extent to which firms are adapting and building resilience to environmental change is crucial information for financial institutions, regulators and governments. While corporates’ physical climate risk exposure of their assets to environmental change can be calculated using models…

Differences in government support for private sector climate change adaptation in developing versus developed countries
Abstract The urgent need for adaptation to existing and emerging impacts of climate change in both the public and private sectors raises a substantial challenge for governance because governmental interventions may either support or hinder climate responses by local communities and private actors…
