Carbon emissions from boreal forest fires more than doubled in 2021, pointing towards a worrying new trend that could exacerbate climate change, scientists have said. Boreal forests, or taiga, is a biome characterised by coniferous forests consisting mostly of pines, spruces, and larches. While they typically account for 10 per cent of

The UK needs a national hydrogen transport strategy to support its decarbonisation plan and efforts to meet net zero, an industry body has said. In the future, hydrogen could be used to fuel vehicles where current battery technologies struggle to provide enough power density such as planes and heavy goods trucks. Hydrogen

Researchers at Linnaeus University have developed a more environmentally friendly way of retrieving cobalt from used lithium-ion batteries. With a liquid solvent made of readily available substances, derived from urine and acetic acid, over 97 percent of the cobalt can be recovered. The researchers see good potential for large-scale application. A

The transition to sustainable aviation fuel (SAF) would require the use of 50 per cent of the UK’s agricultural land, the Royal Society has found. Scientists have not been able to find a single clear alternative to jet fuel that would help the aviation industry achieve net zero. Currently, the UK aviation

Nanoplastics are plastics that have been discarded from our daily lives and that enter ecosystems in a size scale below 1 micro-metter after their physical and chemical disintegration. Recent research has shown that the concentration of microplastics in the major rivers in South Korea is the highest worldwide; it is

M25 grade concrete is a type of concrete mix design that has a compressive strength of 25 megapascals (MPa) after 28 days of curing. The "M" in M25 stands for "mix," and the number 25 refers to the compressive strength of the concrete in MPa. The mix design for M25 grade

Korea Institute of Civil Engineering and Building Technology (KICT) researchers have developed a new technology to predict the levels of damage and ageing of bridges. The DNA (Data, Network and AI) could be used for preventive maintenance and to thus avoid possible disasters. The scientists were aiming to address a significant Korean

Climate policies are typically designed to reduce greenhouse gas emissions that result from human activities and drive climate change. The largest source of these emissions is the combustion of fossil fuels, which increases atmospheric concentrations of ozone, fine particulate matter (PM2.5) and other air pollutants that pose public health risks.

"No water, no life. No blue, no green."This quote from Sylvia Earle, an American marine biologist who holds the record for the deepest walk on the sea floor, speaks to the importance of the ocean and its connection to living things. The ocean also is closely tied to our economic prosperity
