Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world. view more (2007-07-10)
Solar Contribution To 'Global Warming' Predicted To Decrease
New research on the sun's contribution to global warming is reported in this month's Astronomy & Geophysics. By looking at solar activity over the last 11,000 years, British Antarctic Survey (BAS) astrophysicist, Mark Clilverd, predicts that the sun's contribution to warming the Earth will reduce slightly over the next 100 years. This is a... view more... (2003-10-01)
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)
Emissions targets for 2030 will only be reached by banning cars in London

High flyers are the scourge of the skies
EMBARGOED UNTIL WEDNESDAY 16 OCTOBER 2002 19:00 BST UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk Written by DUNCAN GRAHAM-ROWE AIRLINES could boost their emissions of the greenhouse gas carbon dioxide and still halve their impact on global warming. That`s the paradoxical... view more... (2002-10-16)
Carbon emissions trading in Europe: Lessons to be learned
For the past three years, the European Union has been operating the world's largest emissions trading system and the first system to limit and to trade carbon dioxide emissions. view more (2008-06-11)
More efficient use of compressed air
Compressed air is an indispensable source of energy. 60,000 compressed-air systems in Germany consume 14 billion kilowatt-hours of electricity per year, which corresponds to the entire power requirement of the German railroads. Although compressed air is the most expensive source of energy, industry consumes up to 40 percent more than necessary,... view more... (2002-06-26)
Miscounting bioenergy benefits may increase greenhouse gas release
A fixable error in the way carbon is counted in current U.S. climate legislation and in the Kyoto Protocol could undermine efforts to reduce greenhouse gas emissions by using biofuels, says a premier group of national environmental and land use scientists. view more (2009-10-23)
Hybrid vehicle rebates produce scant environmental benefits, high cost
Despite major costs to taxpayers in the U.S. and Canada, government programs that offer rebates to hybrid vehicle buyers are failing to produce environmental benefits, a new UBC study says. view more (2009-08-04)
Northern lights glimmer with unexpected trait
An international team of scientists has detected that some of the glow of Earth's aurora is polarized, an unexpected state for such emissions. view more (2008-04-28)
Ultra-clean coal to power a greener future
Engineers in Nottingham are developing ultra-clean coal that could make power generation 50% more efficient and reduce carbon dioxide emissions by a third. A team at The University of Nottingham is one of only two in the world working on ground-breaking techniques to purify one of the world's main energy sources. view more (2005-05-10)
Kyoto will have little effect on global warming
Life expectancy and prosperity will continue to rise and food production should keep up with population growth, but the Kyoto agreement will have little effect on global warming according to this week's Christmas issue of the BMJ. Using official statistics and global trends, Bj'¸rn Lomborg, Director of the Danish Environmental Assessment Institute... view more... (2002-12-18)
Toxic releases down from North American industry leaders, increasing from other facilities
The latest Taking Stock report from the Commission for Environmental Cooperation (CEC) reveals that a continued decline in releases of toxic chemicals to the environment-15 percent for the United States and Canada from 1998 to 2004-is being driven by a group of industrial facilities that are the largest generators of emissions. view more (2007-10-18)
Commercial ships spew half as much particulate pollution as world's cars
Globally, commercial ships emit almost half as much particulate pollution into the air as the total amount released by cars, according to a new study. Ship pollutants affect both the Earth's climate and the health of people living along coastlines. view more (2009-02-27)
Chemists detect toxic emissions linked to catalytic converters in US
A study scheduled for publication in the Dec. 15 issue of the American Chemical Society's journal, Environmental Science and Technology, shows that for the first time, toxic metals emitted from automotive catalytic converters have been detected in urban air in the United States. view more (2005-12-06)
Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. view more (2008-11-20)

In recommendations to health and... view more... (2002-10-09)
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)
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...
