Need a tech that causes 80% reduction in CO2
"We will ship a billion cars on this planet in the next 15 years or so. Unless a low-carbon technology gets into 80 percent of those 1 billion cars and over time causes an 80 percent reduction of carbon per mile driven, it's not going to be a solution. Everything else is just a toy," - Vinod Khosla, Sep 2008 - Read More

Researchers Discover Way to Listen to Algae, Detect Water Pollution
Researchers have discovered that by shining a laser beam on the algae they can stimulate photosynthesis. Depending on the rate of photosynthesis and the health of algae differing amounts of heat are shot back into the water, creating sound waves. These waves can be picked up by an underwater microphone, allowing the scientists to analyze the health of the algae and the condition of the surrounding water. - Read More

20/20/20 by 2020
In January 2008, the EU specified targets for its member countries to achieve on greenhouse gas emissions. Dubbed "20/20/20 by 2020," they seek to ensure that by 2020, Europe cuts greenhouse gas emissions by 20%, produces 20% of its energy from renewable sources and increases energy efficiency by 20%. - Read More

Rich nations' greenhouse gases fell in 2006: survey
Reuters survey shows that Turkey's emissions have risen most since 1990 among industrialized nations, by 95 percent. Latvia's are down furthest, by 56 percent. Global Carbon Project of leading experts said that world emissions of carbon dioxide were growing four times faster since 2000 than in the 1990s. The surge was led by developing nations, which do not report to the United Nations. The rich countries emissions growth are almost zero - Read More

Air Capture System Can Filter Carbon Dioxide From Any Air, Anywhere
Professor David Keith, director of the Institute for Sustainable Energy, Environment and Economy’s (ISEEE) at the University of Calgary, and his team, captured CO2 directly from the air using less than 100 kilowatt-hours of electricity per ton of CO2. Their custom-built tower captured the equivalent of about 20 tons per year of CO2 on a single square meter of scrubbing material. This about the average amount of emissions that one person would produce in a year in North America. - Read More

Amount of CO2 emitted per year
At present, 22 gigatons (Gt) of CO2 per year (equivalent to 6 Gt C/yr) is emitted as a result of the use of fossil fuels. Worldwide, coal-fired power plants alone result in 1.8 of the 6 Gt C/yr CO2 emission, while the rest (4.2 Gt C/yr) is from the use of fossil fuels in transportation, industry, and private homes. (not sure of date, possibly around year 2000) - Read More

Largest CO2 Sink
Photosynthesis is the biggest CO2 sink on Earth. Each year, the land-based green plants remove about 403 Gt CO2 (equivalent to 110 Gt C) from the atmosphere, while the oceans draw approximately 385 Gt CO2 from the atmosphere. (year 2000 I think) - Read More

Sequestering CO2 in Basalt Formations
(Apr 2008) One option for mitigating CO2 is to sequester CO2 in geologic formations. For the most part, these studies have involved storing CO2 in saline formation, deep coal seams, and depleted oil and gas reservoirs. Another option, however, is basalt formations. Basalt is a dark-colored, silica-rich, volcanic rock that contains cations—such as calcium, magnesium, and iron—that can combine with CO2 to form carbonate minerals. - Read More
EU pumps 10 billion euros for burying CO2
EU is close to agreeing on a source of public funding for power stations to trap and bury CO2. The EU said up to 10 billion euros ($14.20 billion) could be used from a strategic reserve of emission permits to promote the emerging technology. Companies such as Siemens are working on cutting-edge technology to trap CO2, and pump it into empty gas fields and deep underground caverns. (Sep 2008) - Read More
