  • Fossil fuel CO2 emissions up by 29 per cent since 2000, new testing confirms

    The strongest evidence yet that the rise in atmospheric CO2 emissions continues to outstrip the ability of the world’s natural ‘sinks’ to absorb carbon is published this week in the journal Nature Geoscience. An international team of researchers under the umbrella of the Global Carbon Project reports that over the last 50 years the average fraction of global CO2 emissions that remained in the ...

  • Global CO2 emissions may set a record this year

    In its annual report card, scientists working with the GCP reported that although annual emissions in 2009 were 1.3 per cent below the record 2008 figures, partly attributed to the global financial crisis, the concentration of carbon dioxide (CO2) in the atmosphere continued its upward trend to reach a new high of 387 parts per million. Results from the GCP reported in a paper published today in ...

  • CO2 emissions booming, shifting east, researchers report

    Despite widespread concern about climate change, annual carbon dioxide emissions from burning fossil fuels and manufacturing cement have grown 38 percent since 1992, from 6.1 billion tons of carbon to 8.5 billion tons in 2007. At the same time, the source of emissions has shifted dramatically as energy use has been growing slowly in many developed countries but more quickly in some developing ...

  • Stalled economy or not, record year for CO2 emissions

    Each person on the planet produced 1.3 tons of carbon last year—an all-time high--despite a global recession that slowed the growth of fossil fuel emissions for the first time this decade, according to a report published this week in the journal Nature Geoscience. Emissions grew 2 percent last year, to total 8.7 billion tons of carbon dioxide. The report was compiled by scientists affiliated with ...

  • Joule Awarded Patents for High-Volume Ethanol Production from Sunlight and CO2

    Joule Unlimited Technologies today announced the issuance of its first two U.S. patents covering its fundamental method for producing ethanol at volumes and efficiencies far surpassing biomass-dependent processes. The patents relate to methods for increasing the ethanol production capability of a photosynthetic microorganism. Unlike competing technologies that utilize ...

  • Carbon capture and storage: climate impacts

    One proposal for meeting targets for the reduction in emissions of greenhouse gases (GHGs) is to capture and store CO2 that is emitted by fossil fuel burning power stations. In a recent study, researchers demonstrated that carbon capture and storage (CCS) could help mitigate against climate change, especially in the short term. Using CCS, CO2 emitted from energy or industrial plants could be ...

  • Wastewater treatment recycles greenhouse gases

    A laboratory model for dewatering waste-activated sludge (WAS) in two stages - flotation (using recycled greenhouse gases) followed by filtration (using a simple compression cell for dewatering WAS) - has been successfully introduced. Development of full-scale wastewater treatment which also reduces greenhouse gases could follow. Published in the Journal of Water and Climate Change, experiments ...

  • Artificial Cooling Tricky Topic for Climate Panel

    It's Plan B in the fight against climate change: cooling the planet by sucking heat-trapping CO2 from the air or reflecting sunlight back into space. Called geoengineering, it's considered mad science by opponents. Supporters say it would be foolish to ignore it, since plan A - slashing carbon emissions from fossil fuels - is moving so slowly. The U.N.'s expert panel on climate change is under ...

  • Questions and Answers on the proposal for a directive on the geological storage of carbon dioxide

    1) What is carbon capture and storage? Carbon capture and storage is a suite of technological processes which involve capturing carbon dioxide (CO2) from the gases discarded by industry and transporting and injecting it into geological formations. The major application for carbon capture and storage (CCS) is to reduce CO2 emissions from power generation from fossil fuels, principally ...

  • Big potential of cutting greenhouse gases from waste

    There is a big potential to cut greenhouse gases (GHGs) from municipal solid waste management, according to a new report from the European Environment Agency (EEA). The report, 'Waste opportunities – Past and future climate benefits from better municipal waste management in Europe', covers the EU-27 (excluding Cyprus), Norway and Switzerland. It estimates that these countries could make GHG ...

  • China: Olympic-sized growth in carbon emissions

    In 2007, carbon emissions from fossil fuel combustion worldwide reached an estimated 8.2 billion tons, which was 2.8 percent more than in 2006-and 22 percent above the total in 2000.1 The United States and Europe accounted for roughly 4 and 3 percent, respectively, of the growth during this decade.2 India contributed 8 percent, and China, a staggering 57 percent.3 Despite the rapid increase, ...

  • Fact sheet on Biogas - An important renewable energy source

    “Biogas” is a gas produced by anaerobic fermentation of different forms of organic matter and is composed mainly of methane (CH4) and carbon dioxide (CO2). Typical feedstocks for biogas production are manure and sewage, residues of crop production (i.e., straw), the organic fraction of the waste from households and industry, as well as energy crops including maize and grass silage. ...

  • ThermoEnergy Corp. Addresses Clean Coal China Congress and States Case for Clean Coal as Better Bridge to Renewables

    "Clean coalcan providea greener, more cost efficient strategy than gas to bridge the transition between fossil fuels and renewables for baseline power production," said Bob Marrs, Vice President of International Business Development for ...


  • Commercial Cellulosic Ethanol Plant Underway in Iowa

    SIOUX FALLS, South Dakota, October 5, 2007 (ENS) - POET Energy and the U.S. Department of Energy, DOE, have signed a cooperative agreement for a commercial cellulosic ethanol project in Emmetsburg, Iowa that will produce ethanol from corn cobs. Cellulosic ethanol is produced from biomass with starches that are difficult to convert to fuel; sources including corn stover, grasses, wood ...

  • Greenhouse gas concentrations hit yet another record

    The amount of greenhouse gases in the atmosphere reached yet another new record high in 2014, continuing a relentless rise which is fuelling climate change and will make the planet more dangerous and inhospitable for future generations. The World Meteorological Organization’s Greenhouse Gas Bulletin says that between 1990 and ...

  • Auto-sector innovation could create millions of jobs by 2030 and help revitalize Europe’s growth

    Europe could improve its growth prospects and create 500,000 to 1.1 million net additional jobs in 2030 through auto sector innovation. Increased technology to cut fuel consumption would allow the EU to reduce its dependence on foreign oil and deliver between €58 and €83 billion a year in fuel savings for the EU economy by 2030. This shift will achieve the double bonus of mitigating ...
