  • Forest fires increase mercury emissions

    Mercury is a global pollutant arising from many sources, including biomass burning (BMB), which includes both wildfires and intentional fires to clear land. A recent study estimates that mercury emissions from BMB make up 8 per cent of total global mercury emissions. Mercury emissions from BMB have received growing attention. Forests in particular act as mercury sinks because atmospheric mercury ...

  • First Fire First For GE

    GE and Huaneng Guilin Gas Distributed Energy Co. Ltd. said that the first fire of a GE 6F.01 gas turbine has been successfully completed, marking the first application globally for GE’s latest F-class gas turbine. The first fire is a critical milestone during which the gas turbine is switched on and reaches full speed.  The milestone follows several months of installation and ...

  • The future of natural gas - Its on fire

    Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation. That"s the conclusion reached by a comprehensive study of the future of natural gas conducted by an MIT study group comprised of 30 MIT faculty members, researchers, and graduate students. ...

  • Are emissions fueling Australian droughts?

    American scientists have just confirmed that parts of Australia are being slowly parched because of greenhouse gas emissions – which means that the long-term decline in rainfall over south and south-west Australia is a consequence of fossil fuel burning and depletion of the ozone layer by human activity. Such a finding is significant for two reasons. One remains contentious: it is one thing ...

  • Wildfires Spew Carbon Emissions Into the Atmosphere

    BOULDER, Colorado, November 1, 2007 (ENS) - Severe wildfires can contribute as much as vehicles to carbon emissions in some U.S. states, although the amount is highly variable, according to a study based on satellite data. New research published in the journal 'Carbon Balance and Management' quantifies these emissions and suggests fires will complicate emissions monitoring and modelling efforts. ...

  • Future fire – still a wide open climate question

    How the frequency and intensity of wildfires and intentional biomass burning will change in a future climate requires closer scientific attention, according to CSIRO’s Dr Melita Keywood. Dr Keywood said it is likely that fire – one of nature’s primary carbon-cycling mechanisms – will become an increasingly important driver of atmospheric change as the world ...

  • A new global map of ammonia emissions

    For the first time, a global map of atmospheric ammonia emissions has been produced using satellite measurements. This opens up new ways to survey air quality and monitor the Earth's atmospheric chemistry from space. Modern agricultural practices, especially intensive farming methods and widespread fertiliser use, are mainly responsible for ammonia emissions, which have more than doubled since ...

  • Renewable electricity could overtake coal-fired by 2040 according to federal forecasts

    In the next two decades, the nation’s utility sector faces a transformation in which natural gas and renewable energy could become the dominant sources of electricity generation, according to projections from the federal Energy Information Administration (EIA). Among renewable generation sources, both wind and solar generation will surpass hydropower, which has historically been the main ...

  • EU nations agree on stricter emissions testing for diesel

    European Union nations have reached a tentative deal on tougher emissions tests for diesel cars after the Volkswagen scandal showed previous methods were ineffective. The slow phase-in of the new standards, however, drew fire from environmentalists. Emissions from cars on the road in the EU have been found to be four to five times above the official limits. That's largely because the current ...

  • 7,000 Utility Coal-fired Power Plants Are Continuing to Upgrade and Replace

    The market to upgrade and replace components in the existing 7,000 coal-fired power plants is larger than the new equipment market for wind, solar, or gas turbines. The upgrades and replacements are tracked in the Utility Tracking System published by the McIlvaine Company. Many of the power plants in the U.S. are more than 40 years old but are expected to operate another 20 ...

  • Sahara dust, sea spray and fires contribute to bad air quality

    Human activities are the main cause of poor air quality, but natural sources of air pollution also play a role. A new report from the European Environment Agency (EEA) considers how particulate matter from these natural sources affects the air we breathe. The report is the first ...

  • Cogeneration fires up North American power industry, observes Frost & Sullivan

    The North American power industry faces challenges of increased electricity demand, aging equipment, and more stringent environmental standards. Increased use of cogeneration or combined heat and power production (CHP) goes a long way to alleviate most of these issues, as its environmental friendly profile and higher efficiencies make it attractive to industry stakeholders. To promote CHP system ...

  • Energy technologies are not enough to reduce carbon emissions

    Current energy technologies are not enough to reduce carbon emissions to a level needed to lower the risks associated with climate change, New York University physicist Martin Hoffert concludes in an essay in the latest issue of the journal Science. Many scientists have determined that in order to avoid the risks brought about by climate change, steps must be taken to prevent the mean global ...

  • Black Carbon Emissions Cut 90% in California

    In a first-of-its kind study examining the impact black carbon has on climate in California, researchers found the state's efforts to reduce air pollution, particularly from diesel engines, has cut black carbon concentrations by 90% since 1966. This has happened without any noticeable disruption to the lives of the citizens of California, but with tremendous benefits to their health, as well as ...

  • New Report Reveals States and Utilities with Highest and Lowest Power Plant Emissions; Overall U.S. Emissions Decline

    A major new report on U.S. power plant emissions from the top 100 power producers shows that the electric industry cut emissions of NOx, SO2 and CO2 in 2011 even as overall electricity generation increased, largely due to increased use of natural gas and growing reliance on renewable energy. Based on the latest available data, the report also reveals that Wyoming, Kentucky, West ...

  • 7 states sue EPA, seek wood boiler emissions rules

    Seven states filed a federal lawsuit Wednesday against the Environmental Protection Agency over health-damaging air pollution from outdoor wood-fired boilers that have become popular for residential heating. The lawsuit asks a federal court to order EPA to review and adopt updated emissions limits for the boilers, which have been banned in ...

  • EU could cut emissions by 40 percent at moderate cost

    The costs of achieving a more ambitious EU climate target are estimated to be moderate. Upscaling greenhouse-gas emissions reduction from the current 20 percent by 2020 to 40 percent by 2030 would be likely to cost less than an additional 0.7 percent of economic activity. This is a key finding from an international multi-model analysis by the Stanford Energy Modeling Forum (EMF28) and comes at a ...

  • Latest emission control technology could eradicate harmful air pollution hotspots

    Switching to the best available emission control technologies could eliminate 99% of particulate matter pollution ‘hotspots’, a new study suggests. The researchers reached this conclusion by expanding the local-scale capabilities of an existing computer model that estimates the effects of air pollution policies and control measures. Particulate matter (PM) pollution has been linked ...

  • Canada moving closer to 2020 target for GHG emissions reductions

    The International Institute for Sustainable Development (IISD) estimates new federal regulations combined with provincial actions will achieve nearly half the greenhouse gas (GHG) emissions reductions Canada has targeted under the Copenhagen Accord. "Many Canadian GHG emitters are facing carbon costs consistent with emitters in the European Union and at levels well above competitors in the ...
