New process can remove sulfur components and CO2 from power plant emissionsAugust 19th, 2009 WASHINGTON - Scientists at the US Department of Energy's Pacific Northwest National Laboratory have developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. The process could directly replace current methods and allow power plants to capture double the amount of harmful gases in a way that uses no water, less energy and saves money.
US government's 'Cash for Clunkers' program expensive way to reduce CO2August 15th, 2009 WASHINGTON - New estimates by researchers at University of California (UC) Davis have indicated that the US government's 'Cash for Clunkers' program is paying at least 10 times the "sticker price" to reduce emissions of the greenhouse gas carbon dioxide (CO2). While carbon credits are projected to sell in the US for about 28 dollars per ton, even the best-case calculation of the cost of the clunkers rebate is 237 dollars per ton, according to UC Davis transportation economist Christopher Knittel.
Current methods for monitoring CO2 emissions have limitationsAugust 1st, 2009 WASHINGTON - A new report has determined that the current methods for estimating greenhouse gas emissions have limitations that make it difficult to monitor CO2 (carbon dioxide) emissions and verify an international climate treaty. This is part of a new National Research Council letter report to the administrator of NASA, Charles F.
Indian-American devises cleaner way to capture carbon dioxideJuly 23rd, 2009 WASHINGTON - An Indian-American physicist has devised a cleaner and more efficient way of capturing carbon dioxide from its polluting source, like coal-fired power plants. Lawrence Livermore National Lab (LLNL) researcher Amitesh Maiti has come up with a screening method that would use ionic liquids -- molten salt that becomes liquid under the boiling point of water (100 degrees Celsius) -- to separate carbon dioxide from its source.
Molecule that eats carbon dioxide may fight global warmingJuly 16th, 2009 WASHINGTON - The accidental discovery of a bowl-shaped molecule that pulls carbon dioxide out of the air paves the way for exciting new possibilities to deal with global warming. These possibilities include genetically engineering microbes to manufacture those carbon dioxide "catchers", said J.A.
New York's giant 'Carbon Clock' to tick off amount of CO2 emissionsJune 20th, 2009 WASHINGTON - Deutsche Bank has erected a seven-story carbon clock in the center of New York City, which ticks off the tons of carbon dioxide (CO2) being emitted into the atmosphere. The move is being touted as a public relations move designed to raise awareness of global warming.
Scientists find direct relationship between CO2 emissions and global warmingJune 11th, 2009 WASHINGTON - In a new study, a team of scientists has found a direct relationship between carbon dioxide (CO2) emissions and global warming. The study was done by Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment, along with colleagues from Victoria and the UK.
1 litre of milk can generate 1 kg of CO2May 29th, 2009 WASHINGTON - In a new research, scientists have determined that each litre of milk produced in New Zealand can generate nearly 1kg of greenhouse gases - about 85 percent of it on-farm. According to a report in NZPA (New Zealand Press Association), each litre of milk produced causes the emission of greenhouse gases equivalent to 940g of carbon dioxide, meaning New Zealand's leading diary Fonterra's 15 billion litres of milk would produce nearly 15 million tonnes of carbon.
Global carbon emissions to increase 40 percent by 2030May 27th, 2009 WASHINGTON - The level of carbon emissions into the Earth's atmosphere will surge nearly 40 percent by 2030 if the governments can't force more limits on pollutants blamed for global warming, a US report said Wednesday. The Energy Information Administration (EIA) projected that energy consumption will increase 44 percent between 2006 and 2030, mainly because of higher demands from the developing world.
Union of Concerned Scientists gives green travel adviceMay 13th, 2009 Union of Concerned Scientists: Green travel adviceWASHINGTON — A scientists' group has put together a guide to green travel to help you determine which modes of transportation have the smallest carbon footprint, and the group, the Union of Concerned Scientists, says some of the greenest choices can also save money. UCS researchers compared the amount of carbon dioxide — the chief heat-trapping gas that drives global warming — from driving, flying, traveling by train or bus, and also compared per-person emissions for solo travelers versus those traveling in pairs or as a family of four.

Studies say bigger cuts in carbon dioxide emissions needed to keep warming below danger markApril 29th, 2009 To keep warming low, deeper pollution cuts neededWASHINGTON — If the world is going to limit global warming to just a few degrees, it has to slash carbon dioxide pollution much more than now being discussed, two new science studies say. Carbon dioxide from the burning of fossil fuels — coal, oil and natural gas — is the chief cause of global warming.
Carbon sinks losing the battle with rising emissionsMarch 18th, 2009 WASHINGTON - Scientists at the international Copenhagen Climate Change Conference have determined that the stabilizing influence that land and ocean carbon sinks have on rising greenhouse gas emissions is gradually weakening. "Forests, grasslands and oceans are absorbing carbon dioxide (CO2) from the atmosphere faster than ever but they are not keeping pace with rapidly rising emissions," said CSIRO scientist and co-Chair of the Global Carbon Project, Dr Mike Raupach.
NASA to launch carbon dioxide tracking satellite TuesdayFebruary 24th, 2009 WASHINGTON - Scientists hope to get a clearer picture of how the Earth reacts to carbon dioxide with the launch Tuesday of a new spacecraft designed to collect data on the climate-changing gas. The Orbiting Carbon Observatory is set for launch early Tuesday from California and will take about eight million measurements every 16 days for the next two years.
Forest fire has big carbon footprintFebruary 14th, 2009 SYDNEY - Australians are already doing more than their share of heating up the world, with average greenhouse gas emissions near the top of the table. Now the continent's worst forest fires on record have bumped up the size of Australia's carbon footprint.
