Carboxylated cellulose nanofibres are materials with combined sustainability and desirable properties. Here the authors show a synthetic process allowing for scalable and green preparation of such materials.

For battery electrolytes, addressing their safety often leads to compromised electrochemical properties. Here, the electrolyte formulation is not only non-flammable but also supports excellent performance in both K-ion and Li-ion cells.

Government spending for COVID-19 recovery could have enhanced society’s resilience to environmental shocks, but it is unclear whether this was adequately reflected in policies. A study now sheds light on this issue by applying a fiscal policy taxonomy for climate change adaptation and resilience to policies across different countries.

Removal of ultrafine suspended solids from contaminated water in a cost-effective manner remains a global challenge. Here the authors develop an injection-driven filter system that is based on a fully bio-based biodegradable nanofibre hydrogel film to achieve such a goal.

Artificial reefs provide important ecosystem services in marine environments. Accurate knowledge of the area covered by such reefs can help evaluate benefits and risks of such structures. This study describes the physical footprint of artificial reefs deployed in coastal waters of the United States.

Independent impact evaluations of voluntary REDD+ projects to protect forests are needed to provide evidence of their effects. This study evaluates the impacts of a large voluntary REDD+ project in Sierra Leone and finds evidence of slowing deforestation with no socioeconomic harm to local people.

Prescribed burning is a common tool to mitigate the risk of dangerous wildfires. However, careful consideration of the public health impacts should be incorporated into forest management plans.

Ammonia recovery from manure wastewater not only protects the aquatic ecosystem but also contributes to a sustainable nutrient cycle. Here the authors develop an electrochemical process enabling efficient ammonia recovery, with decentralized fertilizer and chemical production, from ammonia-rich manure wastewater.

This study examines productivity and workforce dynamics in the world’s fisheries over six decades, finding that the natural limits of fish stocks combined with technological advances have led to diminishing returns per fisher.

Facilities that store the waste and tailings of mining operations pose a salient threat to biodiversity. Despite international consensus to mitigate mining impacts on local ecosystems, globally, nearly 10% of facilities are located within protected areas and another 20% can be found within 5 km of their boundaries.

Water consumption in line with natural water supply ensures sustainable and equitable access to freshwater resources worldwide. This study assesses whether renewable surface water is enough to meet people’s basic needs and, where it is not, estimates how much groundwater would be required.

As political institutions debate environmental policies, this paper reveals how some members of the European Parliament think about underlying principles of degrowth versus more traditional ‘green’ and economic growth platforms.

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.
