Nearly six billion tonnes of CO2 emissions could be eliminated by 2020 through the focussed use of 17 core technologies in four of the world’s major economic sectors, according to a preview of a report released today just ahead of the United Nations’ COP15 climate change conference starting in Denmark this week.

Next Monday -- the same day climate talks get underway in Copenhagen -- a new search engine, Ecosia, will make its debut. The site generates ad revenue the same way Google and Bing do, but 80 percent of revenues go to the World Wildlife Fund.

Researchers from NASA and Purdue University found that carbon dioxide and methane are not as important as fluorine (F) compounds such as chlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, and nitrogen fluoride when it comes to producing greenhouse gases (GHGs).

The CSIRO and energy distributor, SP AustNet, have started a three-month road trial of a plug-in hybrid electric vehicle (PHEV), which could one day end up in every Australian driveway, after modification of the car using a US-developed conversion kit at the CSIRO’s laboratories in the Melbourne suburb of Clayton.

A new alliance led by IBM aims to improve energy, water, waste and greenhouse gas management through interoperability. Green Sigma applies Lean Six Sigma principles and practices to these areas.

IT services group, EDS and SAP Australia and New Zealand have worked together to develop a new carbon accounting solution which, they claim, will make it easier for Australian companies to comply with new federal government emissions guidelines.

See all those little red lights on your electrical equipment?  Remember all those “black balloon” adverts?  Feeling too lazy to flick the switch at the point after a gaming session?  If so, there are a couple of new products about to hit the Australian market that might save your hip pocket as well as your ever-polluting soul.

On March 28, 1979, a nuclear accident at the Three Mile Island Nuclear Generating Station caused a partial meltdown of one of its reactors but a near total meltdown for U.S. nuclear power over the next 30 years. Now, the nuclear power industry is coming back in the face of a dirty atmosphere.

A team from the United States, Australia, and the United Kingdom found a chemical compound that had replaced a banned greenhouse gas because it was bad for the environment is, itself, also bad for the environment. The culprit is a fumigant with the chemical name sulfuryl fluoride.

On February 24, 2009, NASA is set to launch the Orbiting Carbon Observatory (OCO), the first NASA spacecraft whose sole mission (and, it's an important one)  is to study atmospheric carbon dioxide, an important greenhouse gas contained within our global climate.
