Scientists at the University of Adelaide, in collaboration with the ARC Centre of Excellence for Carbon Science & Innovation, have unveiled two innovative electrolysis systems that generate hydrogen from urea found in urine and wastewater. These systems require 20–27% less electricity than conventional water electrolysis. One design uses a membrane-free setup with a copper-based catalyst […]

As rising seas and saltwater intrusion threaten fertile farmland, scientists are turning to the ocean for solutions. A groundbreaking study in Ambio highlights the potential of seagrass cultivation, particularly Zostera marina (nicknamed “sea-rice”), as a viable grain crop for the future. Projections show that by 2100, up to 620,000 km² of land worldwide could be

North Sea Farm 1, situated within the Hollandse Kust Zuid offshore wind farm about 18 kilometers off Scheveningen, has completed its first commercial seaweed harvest. The project, managed by the non-profit North Sea Farmers and supported by €2 million from Amazon’s Right Now Climate Fund, covers five hectares and uses four underwater nets (each 50

New scientific studies highlight that plant-based solutions can outperform conventional technologies in removing microplastics from water. Natural extracts from okra and fenugreek achieved removal rates of up to 90% in groundwater and 77% in freshwater, surpassing the widely used synthetic polymer polyacrylamide. Researchers say this approach could provide a sustainable, low-cost alternative for addressing the

In May 2025, Breda in the Netherlands was officially recognized as the first National Park City within the European Union, marking a milestone in Europe’s urban sustainability movement. The designation was granted by the National Park City Foundation in collaboration with Salzburg Global and World Urban Parks, following a rigorous peer review and on-site assessment

New research from Tongji University in Shanghai reveals that green roofs can act as powerful filters for microplastics washed down by urban rainfall. In lab trials using rooftop models planted with Rhodiola rosea and Sedum lineare, the combination of vegetation and soil trapped up to 97.5% of plastic particles. Soil layers absorbed the majority, while

For Singapore, shade is more than comfort — it’s a way of life shaped by history and climate. As early as 1822, Stamford Raffles mandated shaded “five-foot ways” in building designs to shield people from heat and sudden tropical downpours. This tradition grew under Prime Minister Lee Kuan Yew, when housing estates and walkways were

A new study suggests that rising global temperatures may unintentionally increase aircraft noise during take-offs. As the atmosphere warms, air becomes less dense, reducing the lift generated by aircraft wings. To compensate, planes climb at shallower angles, staying closer to the ground for longer and spreading noise across wider areas. Researchers estimate that by mid-century,

Australia’s Fortescue Metals Group has taken a bold step toward decarbonisation by securing a massive $2 billion loan in Chinese yuan—a reminder that the path to a green future often requires unlikely alliances. The five-year loan, backed by banks across China, Australia, and beyond, will help Fortescue fund renewable energy projects, slash emissions, and push

    In Taiwan, a forward-thinking entrepreneur is transforming discarded banana plants into eco-friendly textiles, reviving an age-old island tradition with a modern twist. For centuries, banana fibers—once woven into ropes and clothing—were largely abandoned with the rise of synthetic fabrics. Today, with growing concerns about fashion’s environmental footprint, innovators are rediscovering the strength, breathability, and
