White Roofs reduce urban heat island effect
March 11, 2012 07:30 AM - Roger Greenway, ENN

Black roofs have been the norm for commercial buildings for decades since early roofs used a tar-coated paper material and tar based coatings to provide water proofing. Black roofs also add heat which in the winter, is not a bad thing for the building. It turns out that black roofs contribute to the urban heat island effect. This effect, caused not only by black roofs, creates warmer temperatures in urban areas compared to the surrounding suburbs. A study by Stuart Gaffin of Columbia University in New York looked at the effect of roof color on temperatures. On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city's unprecedented effort to brighten rooftops and reduce its "urban heat island" effect.

Cookie Cutter Sustainability
March 9, 2012 08:25 AM - Sarah Whitmore, Do Well Do Good, LLC, Justmeans

For the girl next store or the company down the street, sustainability can be a real head scratcher, especially when you factor in busy schedules, limited cash flow, and confusing choices. Further tensions arise when individuals and companies give in to overly formulaic or prescriptive sustainability strategies. What's right for the single guy in Kentucky with a small plot of land isn't right for the big-city girl in Chicago with a house plant and a public transit card. And what works for the big coffee shop chain isn’t necessarily a good fit for the neighborhood café.

NASCAR: Safe Driving is Green Driving
March 9, 2012 07:08 AM - Tina Casey, Triple Pundit

NASCAR, best known for pushing the speed envelope, has launched a new traffic safety campaign with a sustainable twist. Rather than focusing narrowly on strategies to help drivers to look out for their own lives, the campaign deploys a broad message of taking responsibility for the safety of others. According to a press release launch, the campaign's mission goes far beyond road safety to encourage "personal responsibility for our planet and its people, especially teens."

Fuel Cell Test in Hawaii, GM is on the move
March 7, 2012 07:13 AM - Tina Casey, Triple Pundit

Fuel cells hold great promise as an emission-free way to power cars and other vehicles, but range is the bottleneck. Without a national infrastructure to support fuel cell re-fueling, drivers are pretty much stuck to a network of local charging stations. That could change fairly rapidly, if a test under way by the Department of Defense bears out. In cooperation with several DoD agencies and the car manufacturer GM, the U.S. Army has just launched a pilot fleet of 16 vehicles powered by hydrogen fuel cells in Hawaii. That's small potatoes compared to the tens of thousands of vehicles owned by DoD, but according to the Army it's the largest military fleet of fuel cell vehicles in the world.

GM Announces new trucks, and they are ALL green!

Chevrolet and GMC today announced details of General Motors' bi-fuel 2013 Chevrolet Silverado and GMC Sierra 2500 HD extended cab pickup trucks. Fleet and retail consumers can place orders beginning this April. The vehicles include a compressed natural gas (CNG) capable Vortec 6.0L V8 engine that seamlessly transitions between CNG and gasoline fuel systems. Combined, the trucks offer a range of more than 650 miles. The Silverado and Sierra will be available in standard and long box, with either two- or four-wheel drive.

D.C. Circuit Hears Challenges to EPA Climate Regulations
March 5, 2012 10:45 AM - Jonathan Kalmuss-Katz, Sive Paget & Riesel, P.C.

On February 28 and 29, the D.C. Circuit Court of Appeals heard oral arguments in a series of challenges to the [EPA's] regulation of [GHGs] under the Clean Air Act, far-reaching litigation spanning dozens of parties and at least four separate rules. Decisions from the panel of Judges David Sentelle, David Tatel and Janice Rogers Brown are expected later this year. The rare, two-day argument began with a challenge to EPA's December 7, 2009 finding that emissions of six GHGs, including carbon dioxide, "may reasonably be anticipated both to endanger public health and to endanger public welfare." This "endangerment finding" is the cornerstone of all subsequent action by EPA.

More Americans Believe Climate Change is Happening
March 2, 2012 07:22 AM - Thomas Schueneman, Global Warming is Real

The number of Americans who believe global warming is happening is on the rise, according to a Brookings Institution report on the latest National Survey of American Public Opinion on Climate Change (NSAPOCC) survey conducted in December of 2011. The report shows much of that new-found belief comes from direct experience with independent studies showing that four out of five Americans have been directly impacted by climate change. 2011 was a "year for the record books" bringing record drought and heat waves, hurricanes, floods, winter storms and wildfires. In all, there were 14 record climate and weather-related events in 2011, each causing at least $1 billion in damage. Hurricane Irene alone caused more than $7 billion in damages.

Fire at UK Biomass Power Plant triggered by a single spark
February 28, 2012 06:57 AM - Staff, ClickGreen

Fire investigators believe a spark from machinery triggered the huge fire that swept through Europe's biggest biomass power plant yesterday. Firefighters spent more than 15 hours tackling the fire at the Tilbury power plant on the banks of the River Thames in Essex. The damage is understood to be widespread and fire chiefs believe it will take a further two days to remove the embers of the wood pellets that fuelled the blaze.

Global CFC ban and unintended consequences
February 27, 2012 06:54 AM - Staff, ClickGreen

The Montreal Protocol led to a global phase-out of most substances that deplete the ozone layer, such as chlorofluorocarbons (CFCs). A happy side-effect of the gradual ban of these products is that the Earth’s climate has also benefited because CFCs are also potent greenhouse gases. However, now a "rebound effect" threatens to accelerate the rate of global warming. Hydrofluorocarbons (HFCs), which have been used in recent years in increasing quantities as substitutes for CFCs, are also climatically very active and many are also extremely long-lived.

New Apple HQ to be really green!
February 24, 2012 07:34 AM - Zac Colbert, Guest Author, Triple Pundit

Last year, the late Steve Jobs revealed plans for Apple's new 'Spaceship' building to be located in Cupertino City, California. The futuristic structure should be completed in 2015 and will house approximately 13,000 employees. It may look like it's been plucked from the imagination of Philip K Dick, but what was previously the realm of science fiction has now become science fact. It promises to be one of the most technologically advanced offices in the world, being totally self-sufficient for power with the national grid acting only as backup.
