Buy yourself a tonne of CO2 emissions

sandbag.org.uk is a not-for-profit website that allows members to buy up surplus "permits to pollute" that form the currency of the European Union's emissions trading scheme (or EU ETSs). Members can then "retire" them so that they cannot continue to be traded between the industrial polluters - cement, steel and car manufacturers etc - forced by EU regulation to operate within the system. "I suppose it's a bit like burning money in front of someone so they can't spend it on something bad," says the founder, Bryony Worthington, to the Guardian. Their site also has a map where you can see the locations of the UK's biggest carbon emitters and their annual allowances. A tonne of carbon is priced at about €25 or £20 or $35.

Sucking CO2

Sucking CO2 out of the air has long been a holy grail for solving global warming; Richard Branson has promised $25m to anyone who succeeds. Of course it's already been done, but the amount of energy required doesn't make it net carbon positive. Now a team in Arizona, led by Klaus Lacknet under the company of Global Research Technologies, says it has made a significant breakthrough that massively reduces the amount of energy required - the "project has reached the stage where it is quite clear we can do it." The planned prototype, which will be finished in two years, will cost $200,000 USD, be smaller than a shipping container and be capable of eliminating around 1 ton of CO2. Even if it works many hurdles remain but it portends a cooler future for air-capture technology.

Maps revolutionize study of carbon dioxide emissions

New maps show US fossil fuel emissions aren't where we thought they were. The Vulcan Project collects more accurate data at a higher resolution than previous studies. Explanatory video. via Other visualizations of CO2 emissions include NASA forecasts and plots, CARMA, which monitors power plant emissions, and the European Space Agency, which uses high resolution spectrometer data (video download). This Australian PSA offers an entirely different kind of visualization.

Filtering our air

The University of Columbias Earth Institute has successfully demonstrated carbon dioxide air capturing. As to what could be done with the carbon dioxide after, the IPCC has some ideas (pdf). Unfortunately they don't state how much energy these machines consume or how expensive (toxic, etc.) their prodction is going to be.

Climate change a 'questionable truth'. Margaret Wente looks beyond the hysteria surrounding the climate change debate. Hysteria her own newspaper has been contributing to.

CO2 'highest for 650,000 years'

CO2 'highest for 650,000 years' Current levels of the greenhouse gases carbon dioxide and methane in the atmosphere are higher now than at any time in the past 650,000 years. (Found via Treehugger) Sounds like it's time to buy that lovely oceanfront property in Kansas.
