Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the properties they need: add defects. view more (2008-06-17)
'Green' research at Louisiana Tech results in new geopolymer concrete technology
Dr. Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center, is conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions. view more (2009-09-30)
Kentucky Geological Survey involved in global climate change research
Researchers at the Kentucky Geological Survey are studying options to reduce the amount of carbon dioxide emitted into the atmosphere. Carbon dioxide is produced by the burning of coal, gasoline, and natural gas and has been linked to global warming. view more (2005-07-15)
Tracing ultra-fine dust
Fine particle emissions have been the subject of heated debate for years. People who live near industrial plants see the smoke being discharged into the atmosphere and wonder how harmful it is. view more (2009-10-06)
Study shows maritime shipping makes hefty contribution to air pollution
Commercial ships emit almost half as much particulate pollutants into the air globally as the total amount released by the world's cars, according to a new study led by the National Oceanic and Atmospheric Administration and the University of Colorado at Boulder. view more (2009-02-27)
Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate. view more (2008-09-10)
Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
Permafrost - the perpetually frozen foundation of North America - isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. view more (2007-08-10)
Researchers in Finland working on a comprehensive model of the carbon cycle
Researchers in Finland are working to develop a comprehensive, multidisciplinary model of the carbon cycle and its impacts on climate change in northern ecosystems. The focus of work in the Academy of Finland’s Global Change Research Programme (FIGARE) has been on the uptake and release of carbon in different ecosystem reservoirs, the... view more...

Boiler modifications cut mercury emissions 70 percent or more, research team finds
Researchers at Lehigh University's Energy Research Center (ERC) have developed and successfully tested a cost-effective technique for reducing mercury emissions from coal-fired power plants. view more (2005-10-04)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures. view more (2008-01-03)
Energy, technology and environmental challenges: European research predicts bleak world picture in 2030
In 2030 the world's energy consumption will have doubled; fossil fuels, namely oil, will continue to dominate as energy sources and carbon dioxide emissions will be nearly twice those recorded in 1990, according to research published today by the European Commission. the "World Energy, Technology and Climate Policy Outlook" sets out for... view more...

NASA study says climate adds fuel to Asian wildfire emissions
In the last decade, Asian farmers have cleared tens of thousands of square miles of forests to accommodate the world's growing demand for palm oil, an increasingly popular food ingredient. view more (2009-05-01)
Low-carbon living takes off in the US
Cohousing offers a low-carbon lifestyle, and developers are poised for a market that could soon burgeon in the US, according to a new study. Until now, cohousing has occupied a niche market in the US, but the paper by Dr Jo Williams at UCL (University College London) suggests the situation is changing. view more (2008-04-09)
Biodiesel could reduce greenhouse gas emissions
A CSIRO report released today confirms that using pure biodiesel or blending biodiesel with standard fuel could reduce greenhouse gas emissions from the transport sector. view more (2007-11-28)
Carbon dioxide emissions predicted to reduce density of Earth's outermost atmosphere by 2017
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU). view more (2006-12-12)
Device Burns Fuel with Almost Zero Emissions
Georgia Tech researchers have created a new combustor (combustion chamber where fuel is burned to power an engine or gas turbine) designed to burn fuel in a wide range of devices — with next to no emission of nitrogen oxide (NOx) and carbon monoxide (CO), two of the primary causes of air pollution. view more (2006-06-22)
Global warming: Our best guess is likely wrong
No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect. view more (2009-07-15)
Coral reefs may start dissolving when atmospheric CO2 doubles
Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. view more (2009-03-10)
Replacing corn with perennial grasses improves carbon footprint of biofuels
Converting forests or fields to biofuel crops can increase or decrease greenhouse gas emissions, depending on where - and which - biofuel crops are used, University of Illinois researchers report this month. view more (2008-12-03)
