Argonne tests validate BMW Hydrogen 7 emissions well-below SULEV
Independent tests conducted by engineers at the U.S. Department of Energy's (DOE) Argonne National Laboratory on a BMW Hydrogen 7 Mono-Fuel demonstration vehicle have found that the car's hydrogen-powered engine surpasses the super-ultra low-emission vehicle (SULEV) level, the most stringent emissions performance standard to date. view more (2008-03-31)
Are we trading energy conservation for toxic air emissions?
A team of Yale scientists has found that certain countries and some U.S. states stand to benefit from the use of compact fluorescent lighting more than others in the fight against global warming. Some places may even produce more mercury emissions by switching from incandescent light bulbs to compact fluorescent lighting. view more (2008-10-01)
KTH research: Increased combustion reduces carbon dioxide emissions
New, previously overlooked technology could dramatically reduce emissions of carbon dioxide. Bio-energy facilities that capture carbon dioxide from combustion gases would even make it possible to reduce the amount of carbon dioxide in the atmosphere. The idea of capturing carbon dioxide and storing it in bedrock is not actually new. In recent... view more... (2001-11-23)
Fans use too much electricity
From our kitchens to industrial buildings, we cannot do without fans - even if we are only seldom aware of them. They cool the processor in our home computers, or rotate in the cooling towers of large power stations. But they need electricity to be able to do their job. For Europe, the Fraunhofer Institute for Systems and Innovation Research ISI,... view more... (2002-08-29)
MIT: Nanoengineered concrete could cut CO2 emissions
While government leaders argue about the practicality of reducing world emissions of carbon dioxide, scientists and engineers are seeking ways to make it happen. view more (2007-01-30)
Food-crop yields in future greenhouse-gas conditions lower than expected
Open-air field trials involving five major food crops grown under carbon-dioxide levels projected for the future are harvesting dramatically less bounty than those raised in earlier greenhouse and other enclosed test conditions — and scientists warn that global food supplies could be at risk without changes in production strategies. view more (2006-06-30)
Modeling of long-term fossil fuel consumption shows 14.5 degree hike in temperature
If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day. view more (2005-11-02)
Press Invitation: The Bonn Agreement on the Kyoto Protocol - examining the outcomes
Meeting held by Royal Institute of International Affairs' Energy & Environment Programme 10.00 - 11.30am, on Wednesday 8 August at Chatham House, 10 St. James's Square, London In a presentation to examine the outcome of the Bonn negotiations on the Kyoto Protocol, to follow Henry Derwent (Department for Environment, Food & Rural Affairs... view more...

Plants' internal clock can improve climate-change models
The ability of plants to tell the time, a mechanism common to all living beings, enables them to survive, grow and reproduce. view more (2009-07-06)
Rocks could be harnessed to sponge vast amounts of CO2 from air, says study
Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide. view more (2008-11-06)
Go with the flow
Traffic flows account for as much as one-third of global energy consumption. But unconventional changes in managing traffic flow could significantly reduce such waste and lower harmful CO2 emissions, says Dirk Helbing. view more (2007-11-16)
Low-cost reusable material could facilitate capture of carbon dioxide from power plants
Researchers have developed a new, low-cost material for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide - and can be reused many times. view more (2008-03-10)
Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans. view more (2006-04-03)
Power plants are major influence in regional mercury emissions
The amount of mercury emitted into the atmosphere in the Northeast fluctuates annually depending on activity in the electric power industry, according to researchers at the Yale School of Forestry & Environmental Studies. view more (2006-07-24)
VTT opens research lab for heavy vehicle emissions
VTT, Technical Research Centre of Finland opens a new lab which is comprehensive and significant measured even by international standards. VTT`s new research laboratory for research of heavy duty vehicles will focus on truck and bus energy and emissions research. With the laboratory`s comprehensive facilities, it will be possible to combine VTT`s... view more... (2002-03-26)
World's oldest rocks show how Earth may have dodged frozen fate of Mars
Carbon dioxide, a greenhouse gas that has become a bane of modern society, may have saved Earth from freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks. view more (2007-02-06)
Land won't soak up carbon indefinitely say top scientists
A paper to be published this week in the journal Nature provides a new global view of terrestrial carbon sources and sinks and warns that current sinks cannot be counted on to mop up carbon dioxide emissions indefinitely. The results have potential implications for the Kyoto Protocol negotiations where recent difficulties have included a lack of... view more... (2001-11-06)
Smithsonian scientists highlight environmental impacts of biofuels
Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production. Corn, soy and sugarcane come up short. view more (2008-01-04)
High-tech sieve sifts for hydrogen
Whether it's used in chemical laboratories or the fuel tanks of advanced automobiles, hydrogen is mostly produced from natural gas and other fossil fuels. view more (2006-02-06)
Too little scope for development in today's aircraft technology
New technology can do much to improve certain aspects of aviation in terms of sustainable development over the next fifty years, but this will be nowhere near enough to compensate for the expected growth in air travel. view more (2007-06-27)
