New technologies and policies that save energy, remove atmospheric carbon and limit greenhouse gas emissions are needed to fight global climate change — but face daunting technological, economic and political hurdles, a Michigan State University scientist said.
The good news: Basic actions taken by everyday people can yield fast savings at low cost, according to MSU [...]

Trains, planes, buses and automobiles do not only effect the environment via their exhaust pipes. There is a full life-cycle of processes associated with getting from a to b that we rarely acknowledge.
Published today in IOP Publishing’s Environmental Research Letters, Monday, June 8, 2009, researchers from the Department of Civil and Environmental Engineering at the [...]

Combating climate change may not be a question of who will carry the burden but could instead be a rush for the benefits, according to new economic modeling presented today at “Climate Change: Global Risks, Challenges & Decisions” hosted by the University of Copenhagen.
Contrary to current cost models for lowering greenhouse gas emissions and fighting [...]

High gasoline prices could lead to a dramatic saving in US greenhouse-gas emissions. That’s the conclusion of economists in the US, who suggest high fuel prices are turning consumers off SUVs and onto smaller, more fuel-efficient vehicles.
What’s more, car owners are predicted to cut back on driving in order to save money. Together, these changes [...]

Scientists at Newcastle University have pioneered breakthrough technology in the fight to cut greenhouse gases.
The Newcastle University team, led by Michael North, Professor of Organic Chemistry, has developed a highly energy-efficient method of converting waste carbon dioxide (CO2) into chemical compounds known as cyclic carbonates.
The team estimates that the technology has the potential to use [...]

The old adage, “We are what we eat,” may be the latest recipe for success when it comes to curbing the perils of global climate warming. Despite the recent popular attention to the distance that food travels from farm to plate, aka “food miles,” Carnegie Mellon researchers Christopher L. Weber and H. Scott Matthews argue [...]

Creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%. Earlier promising predictions, based on mathematical models and wind tunnel tests by TU Delft, have been confirmed during road tests with an adapted trailer. This means that [...]

A new, high-resolution, interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren’t all where we thought.
“For example, we’ve been attributing too many emissions to the northeastern United States, and it’s looking like the southeastern U.S. is a much larger source than we had estimated previously,” says Kevin Gurney, [...]

Now that scientists have reached a consensus that carbon dioxide emissions from human activities are the major cause of global warming, the next question is: How can we stop it? Can we just cut back on carbon, or do we need to go cold turkey? According to a new study by scientists at the Carnegie [...]
