While humans are still struggling to get rid of unwanted carbon it appears that the heavens are really rather good at it. New research by astrophysicists at the University of Warwick has discovered that a mystery stellar explosion recorded in 2006 may have marked the unusual death of an equally unusually carbon-rich star.

More than 20 million tons of plastic are placed in U.S. landfills each year. Results from a new University of Missouri study suggest that some of the largely petroleum-based plastic may soon be replaced by a nonpolluting, renewable plastic made from plants.

Publications ranging from the journal Science to Time magazine have blasted biofuels for significantly contributing to greenhouse gas emissions, calling into question the environmental benefits of making fuel from plant material.

A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers.

Would shrinking your carbon footprint, recycling more, and going green be easier if you could monitor your household's environmental impact? That's the question a team of Canadian industry consultants set out to answer. They report their findings in a forthcoming issue of the International Journal of Environmental Technology and Management from Inderscience Publishers.

HP today announced new research initiatives from HP Labs, the company’s central research arm, aimed at developing new technologies and business models that leave a lighter carbon footprint.

Could a business practice usually reserved for boosting profits be used to help turn companies green by reducing their energy use? Writing in the International Journal of Six Sigma and Competitive Advantage (IJSSCA), researchers in India provide an answer.

The University of Bristol is planning to develop two state-of-the-art energy centres that will cut its carbon emissions by nearly a quarter and dramatically increase its energy efficiency.

An innovation called Carbon Hero may help reduce global warming by making people more aware of their carbon footprint. Regional prize winner in the 2007 European Satellite Navigation Competition, sponsored by ESA’s Technology Transfer Programme, the device uses satellite navigation technology to track journeys.

How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming.
