Oil and gas installations, offshore windfarms and other artificial constructions may enhance marine ecosystems and have been proposed to help meet conservation targets. A study synthesizes existing literature to reveal global patterns in their ecological effectiveness.

A growing population, climate change and the environmental impacts of conventional agricultural practices are worsening food insecurity. New research shows that use of nanofertilizers can increase food production while simultaneously decreasing the negative environmental effects of agriculture.

Phase transitions are detrimental to the cyclability of layered oxide cathodes for next-generation sodium-ion batteries. Now, two complementary studies suggest principles on how to navigate through the vast compositional space for better electrochemical performance.

Polyamides are an important class of polymers, yet their fossil-based manufacturing markedly contributes to environmental pollution. A recent breakthrough unlocks a sustainable pathway to recyclable polyamides produced directly from biomass.

Global food systems, a major driver of biodiversity loss, are exposed to multiple stressors, including geopolitical shocks like wars. A study now shows the impacts of the Russia–Ukraine conflict on the global food market, and the consequences in terms of cropland expansion and biodiversity harm.

Most glass fibre-reinforced plastics (GFRPs) waste currently ends up in either landfills or incineration facilities, resulting in adverse environmental impacts and waste of resources. Now, a flash Joule heating technology can achieve rapid and effective upcycling of GFRPs waste into SiC, a material that has a wide range of applications.

To realize sustainability transitions, there is a need for broad societal support. A study now shows that images can be influential in building that support, even in the case of policy decisions to invest in greener urban transportation, which more sceptical citizens would typically not endorse.

Myriad structures, from purpose-built concrete modules to decommissioned petroleum platforms, have been deployed in US waters to create artificial reefs. Assessing their spatial coverage would help marine spatial planning but the task is challenging. Now a study does that and reveals some important ecological insights.

Whether on a hike, in a remote disaster zone or in your own home, access to clean water is critical. Filtration of freshwater to remove ultrafine particles like micro/nanoplastics, pathogens or other toxic components is unfortunately usually quite expensive, unportable and environmentally unfriendly.

The nitritation process, namely the biological conversion of ammonia to nitrite, is a pivotal approach in sustainable sewage management but remains challenging to implement in practice. Now a strategy shows remarkable efficiency in swiftly initiating and maintaining sewage nitritation, even under industrially relevant conditions.

Eco-sensitive river basins are facing pressure to reduce carbon emissions and rapidly grow their economies. Now, a study identifies the exploitable hydropower potential in low-carbon futures, and the risks of relying on large-scale hydropower projects to integrate variable renewable energy in a decarbonized world.

Human changes to freshwater flows affect marine ecosystems, but such impacts are rarely considered in development plans involving dam building and water abstraction from rivers. Now research shows how approaches that integrate flow management and marine fisheries can improve both freshwater and coastal ecosystem sustainability.

Quantifications of the impacts of sea-level rise in small island states are urgently needed. Focusing on flooding from sea-level rise, a study now estimates the impacts in terms of cost, land loss and population exposure across all small islands worldwide.

Humans and mangroves adapt to conditions arising from subsidence and relative sea-level rise. Quantifying adaptation responses provides an innovative and cost-effective means of characterizing spatial variation in subsidence and relative sea-level rise and delivers critical information for coastal planning.

Siloed exploitation, management and planning of the oceans have resulted in escalating damage to ocean biodiversity and conflicts among users. A study now provides a set of principles to ensure participation and inclusion of all rights-holders and stakeholders towards transformative ocean governance to enable sustainability.

Contemporary plastics upcycling methods rely on the use of hydrogen and solvents, which make the process not environmentally friendly. Now a solvent- and hydrogen-free strategy can convert high-density polyethylene into separable hydrocarbons with high efficiency.

Bisphenol A (BPA) is an industrial chemical produced in large quantities for use primarily in the manufacturing of plastics. However, its adverse effects on human health are driving the development of safer and more sustainable alternatives. Now, a synthetic route enables such an alternative, starting from renewable lignin biomass.

Addressing the global water crisis requires technologies suited to harvest alternative sources of freshwater. Now, a bifunctional fog harvester offers a promising avenue for concurrent water collection and decontamination.

Despite being one of the most managed resources on earth, water availability and access can be the subject of illegal trade. These markets and their governance need research as water becomes scarcer.

Aromatic compounds have broad applications in our daily life, but their production currently relies heavily on fossil resources. Now, a strategy enables synthesis of benzenoid aromatics from bioderived feedstock, paving the way to the more sustainable production of aromatics.
