No less than one third of a car's fuel consumption is spent in overcoming friction. This friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction from 10 to 80 percent in various components of a car, according to a joint study by VTT Technical Research Centre of Finland and Argonne National Laboratory in the United States.
Automakers have made great strides in fuel efficiency in recent decades — but the mileage numbers of individual vehicles have barely increased. An MIT economist explains the conundrum.
New research suggests that China's impressive feat of cutting Beijing's pollution up to 50 percent for the 2008 Summer Olympics had some help from Mother Nature.
California's Air Resources Board (ARB) is proposing new rules to reduce greenhouse gas emissions from vehicles.
A project to close one of the world's largest landfills, the 927-acre Bordo Poniente Landfill in Mexico City will stem the city's largest source of greenhouse gas (GHG) emissions, while creating renewable energy and local jobs.
Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change.
A Yale study examining the impact of aviation on climate change found that removing sulfur from jet fuel cools the atmosphere. The study was published in the Geophysical Research Letters.
No laggards, those bees and plants. As warm temperatures due to climate change encroach winter, bees and plants keep pace.
Earlier this year the federal government introduced sector-by-sector emissions reduction regulations as its stand on climate change. However, according to Prof. Al Lucas and co-author Jenette Yearsley, the Constitution limits Ottawa's ability to enact climate change legislation limiting greenhouse gas emissions.
A major new scientific review, involving more than 30 scientists from Australia, New Zealand and the Pacific Islands sets out our current knowledge of the impacts of climate change on biodiversity in the latest special edition of the scientific journal Pacific Conservation Biology.
The team at U.K.-based Glow-worm, has put together an eco-friendly holiday guide to help us all achieve a low carbon Christmas. Bursting at the seams with facts, figures and energy saving tips for 25 days of December.
Emergency campaign calls for immediate action from the private sector to reduce their carbon footprint while supporting innovative forest protection projects.
As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates, according to survey results from 41 international scientists published in the Nov. 30 issue of the journal Nature.
A lighter, greener, cheaper, longer-lasting battery. Who wouldn’t want that?
Explaining the purchase of a hundred pounds of dry ice to the authorities might be a bit awkward for some people; however, for Ari Jumpponen, associate professor of biology at Kansas State University, it's just another day as a scientist.
American energy use went back up in 2010 compared to 2009, when consumption was at a 12-year low.
Holm oaks and other forests in lowland areas of Mediterranean mountains could expand by up to 350 percent due to global warming. In contrast, those forest formations that are more adapted to cold and humid conditions, such as beech and Sylvester pines, could shrink by up to 99 percent.
During the summer 2003, high temperatures and drought conditions in Europe led to a reduction of the wind force with direct consequences on the wind energy power, reduced by 22 percent. The study was recently published in Journal of Climate.
Slow-moving winter weather systems that can lead to massive snowfalls are more frequent during the decades when the North Atlantic Ocean is warmer than usual, a new NASA study finds. The study demonstrates that the impacts of such systems, which are often fueled by an atmospheric phenomenon known as atmospheric blocking, go far beyond the atmosphere and can trigger changes in ocean circulation.
Some people may consider them pests, but ants are key to many plants’ survival.
