A Woman’s Work…
The Governor’s Global Climate Summit ended with Oxfam America’s inaugural Sisters on the Planet Climate Leader Awards. Thanks to Karen Solomon at Opportunity Green, I was able to attend. The event showcased the work that women all over the world are doing to adapt to climate change. Sisters on the Planet is committed to exposing how livelihoods of the majority of the planet’s women are the most severely impacted by climate change. To quote the brochure:
“But if you remember one thing about Sisters on the Planet, make it this: Climate change is already having a disproportionate impact on poor people in the US and abroad, and it’s hitting women hardest.”
Oxfam is working with women all over the world to develop low-cost adaptation techniques relevant to the regions they’re in. Adapting to global warming requires a range of tactics, from helping families in flood-prone regions elevate their homes, build floating vegetable gardens, and store seeds and other necessities safely to helping farmers in drought-prone areas plant trees, drill wells and improve their irrigation techniques. Oxfam’s publication, Adaptation 101, shows the overall cost of some of these projects, and at what level they need to be carried out- in the community or nationally.

The U.S. EPA has found that a simple, inexpensive rooftop solar panel can provide enough power to run a fan and remove toxic fumes from homes sitting on contaminated ground. The EPA gave solar-powered venting a test run on several homes earlier this year, in a Superfund action aimed at tricholoroethene (TCE) vapors in a Grand Prairie, Texas neighborhood. The pollution had been traced to a site occupied by the now-bankrupt Delfasco Forge company.
Compared to conventional remediation that involves weeks, months or even years of work along with a potentially huge carbon footprint for transporting or capping soil, the solar-powered exhaust systems took mere hours to install and resulted in an immediate 95% reduction in TCE vapors within the homes. The EPA plans to extend the program this fall to other homes affected by the Delfasco site.

More sulfur dioxide and other acid gasses could be scrubbed from power plant emissions with a new technology developed by the Department of Energy’s Pacific Northwest National Laboratory. The new method, Reversible Acid Gas Capture, is a sustainable twofer: it doubles the amount of pollutants currently captured by the leading water-based scrubber, and it is far more energy-efficient. David Heldebrant, the scientist who headed the PNNL research team, points out that the technology easily lends itself to a retrofit for existing power plants. That’s good news for reducing pollution from coal-fired power plants, but it would be a mistake to call it a win for “clean coal.”

The European Union (EU) released a 94-page list of airlines that must reduce their emissions or will be banned from European airports two days ago. These are airlines of various sorts from all around the world. Some top players include United Airlines, US Airways, and the US Navy. Read the rest of this entry »

Those of us who don’t live in developing countries might not always remember that the majority of the world still uses biomass-fired cookstoves that produce smoke and other toxins. It’s a serious problem–indoor air pollution kills 1.6 million people yearly. Enter the SCORE (Stove for Cooking, Refrigeration, and Electricity), a $33 cookstove developed by researchers at the University of Nottingham that doubles as an electrical generator.

The discovery of a tiny bowl-shaped molecule which collects carbon dioxide right out of the air has beckoned some creative solutions to global warming.
By genetically engineering microbes to manufacture the handy molecule, scientists hope to make it useful as an industrial absorbent for CO2 capture. That could help clean up smokestacks from dirty coal-fired power plants, but it’s also possible that the molecules could be used for pulling carbon dioxide right out of the ambient air.

It’s “not supposed to do that,” but it is: salt has revealed a previously undiscovered talent for stretching. The startling revelation was made by researchers from Sandia National Laboratories and the University of Pittsburgh, using a powerful Interfacial Force Microscope. The discovery of stretchable properties in salt could lead to the development of more efficient desalination technology, and it could also provide more insight into the potential for alternative fuels to contribute to smog formation.

When it comes to environmental news, doom and gloom often rules the day. And it’s easy to get discouraged. But scientists from Yale University say most polluted ecosystems can recover in as little as 5 or 10 years.
The study means it’s not too late to turn things around if societies commit to cleanup, restoration and sustainability, according to Yale’s analysis of 240 independent studies. The findings appear in this month’s issue of the peer-reviewed journal PLoS ONE.

Experts call energy efficiency the low-hanging fruit, because it’s cheaper to cut power use than create new energy from fossil fuels like coal.
But our creature comforts — like iPods, cell phones, PCs and plasma TVs — are sucking the life out of advances in energy efficiency around the world, the International Energy Agency says.
In other words, too much fruit is rotting on the vine.
The IEA says in a new “Gigawatts and Gadgets” report that electricity consumption from power-hungry electronics could cause household energy use to triple by 2030. That means increased greenhouse gases from electric generation, and increased electric bills for creating that power. Read the rest of this entry »

According to GreenSpaces, these three plants not only lead to fresher indoor air…but also an increase in productivity!
GreenSpaces has tested these plants for the past 15 years in a 20 year old, 50,000 ft2 building with over 300 occupants, and 1,200 plants! A study published on September 8, 2008 found that there is a 42% probability of increasing blood oxygen by 1% if one is inside the building for 10 hours. In fact, the building is rated the healthiest building in Delhi by the Government of India. Read the rest of this entry »
