Theories of change have been a staple of sustainability research, but how to connect such overarching concepts to actionable items can be a struggle. This study uses coastal wetlands to demonstrate a potential framework for integrating indicators of conservation enabling conditions into theories of change.

Gold mining has a substantial impact on the surrounding environment, especially in terms of mercury release and high energy consumption. Retorts have reduced the magnitude of mercury emissions in the Brazilian Tapajós River basin, but gold mining still releases 16,000 kg of CO₂ equivalent per kilogram of gold.

Water resource development can have important downstream impacts on ecological functioning and affect socio-economic outcomes associated with marine fisheries. This study modelled the catchment-to-coast effects of reductions in freshwater flowing to estuaries in Australia.

Pairing a cobalt-free cathode with an Earth-abundant SiO_x anode is favourable from a sustainability perspective. Here the electrolyte design allows for such a combination as well as exciting battery performance.

Solar-driven biomanufacturing using semiconductor biohybrids has the potential to achieve sustainable chemical production, but it is challenging to scale up. Here, the authors present a strategy to achieve scalable solar-driven waste-to-chemical conversion using wastewater-derived biohybrids.

Tools to promote more environmentally friendly behaviours increasingly include nudges but evidence about their effectiveness is mixed. Using an online experiment, this study tests whether reflective strategies increase the effectiveness of nudges in promoting more sustainable diets.

Climate change-induced sea-level rise and coastal extremes pose serious threats to Small Island Developing States (SIDS). This study provides a coastal flood risk assessment for SIDS globally and reveals the need for timely adaptation.

Catalytic upcycling of waste plastics has multiple benefits from a sustainability perspective, but available processes struggle with chlorine-containing feedstocks. Here the authors propose a strategy capable to upcycle chlorine-containing plastic wastes to valuable chemicals.

Rural coastal communities depend on natural ecosystems, such as mangrove forests and wetlands, for protection against local sea level rise. Mangroves prove relatively resilient to sea level rise; however, landward shoreline retreat persists, forcing rural communities from coastal settlements.

The UN 2030 Agenda for Sustainable Development recognizes the need to transform governance for the world to develop sustainably. Using a mixed method approach, this study presents 13 principles for transformative ocean governance that can help turn ocean-use practices into more sustainable ones.

Heavy-duty vehicles are responsible for a substantial portion of road emissions from fossil-fuelled vehicles and cause harmful air pollution. Transitioning to electric heavy-duty vehicles would provide substantial health benefits, especially in Black and Hispanic/Latino urban neighbourhoods.

Clean-up of oil spills is a global challenge because current methods are ineffective when facing highly viscous oil with low fluidity. Here the authors develop a tool for efficient and high-throughput clean-up of highly viscous oil spills.

Coral reefs and related fish populations are under threat of extinction unless additional conservation measures are put in place. Focusing on 12 countries with diverse income and tropical reef proximity, this study analyses the willingness of the public to pay for global coral and reef fish conservation.

Bisphenol A (BPA) is an essential building block for manufacturing plastics, but its adverse health effects have become a major concern. Here the authors show a zeolite-catalysed synthetitic route to bio-renewable BPA alternatives that feature excellent safety and preserve efficacy of function.

Levees can obscure the public perception of flood risk, reflected in accelerated rates of development in floodplains relative to surrounding areas. Effective regulation and legislative measures can reverse this effect for more sustainable management.

Reductions in air pollution in the United States over the past two decades have led to positive results for forest growth and survival. However, further measures are needed to protect sensitive tree species and bolster forest biodiversity

Our daily lives and economic activities increasingly rely on 5G mobile networks, but their carbon emissions are concerning. Here the authors quantify the carbon emissions of 5G mobile networks in China and propose a strategy to reduce them, paving the way to sustainable mobile communication infrastructures.

Atmospheric water harvesting is challenging due to the presence of airborne pollutants. The authors show a device design that enables fog capture with simultaneous pollutant decomposition powered by sunlight.

Radiative cooling textiles provide a sustainable means for personal thermal management. Here the nano-textile design realizes an unprecedented combination of human body cooling in both indoor and outdoor conditions without compromising wearability.

As the availability of affordable freshwater in urban settings becomes ever more urgent around the world, this study looks at how an unregulated, informal market meets demands at the expense of groundwater resources.
