Green Options

A lawsuit to overturn the approval of Tejon Mountain Village - a luxury development which will destroy fragile California condor habitat - has been filed by a coalition of environmental justice advocates, Native Americans, endangered species advocates, and local residents.

The Center for Biological Diversity, Wishtoyo Foundation, TriCounty Watchdogs, and the Center on Race, Poverty & The Environment filed the suit under the California Environmental Quality Act in Kern County Superior Court in Bakersfield.

According to a new report published by the Worldwatch Institute, global emissions caused by the “lifecycle and supply chain of animals raised for food”  are much higher than previously thought.   Environmental advisers Jeff Anhang and Dr. Robert Goodland, report previous estimates of greenhouse gases caused by livestock were in fact, underestimated.   

Time-traveling to 2010 reveals how some of Washington’s worst-kept secrets will catch up with President Obama and cripple his climate agenda.

Suddenly, “green business” is a little low on green and high on business. Companies that were built to take on Big Oil are now sharpening their elbows in the lobbying fight to make sure that the bottom line does not fall victim to grid enhancements that are built out by someone else.

Nitrous oxide, more commonly known at your dentist’s office as laughing gas, is now the most prevalent man-made substance damaging the ozone layer. And it’s a greenhouse gas. Sadly, the joke’s apparently on us.

This column highlights the top economic stories of the week.

While Detroit has benefited from Cash for Clunkers, foreign automakers have gained even more. Some critics of the program warned that because it let consumers buy domestic or foreign cars, Clunkers could end up spending more American tax dollars to help foreign companies than American ones. More on this story here.

With irresponsible banking practices taking the blame for bringing about the global economic crisis, there has been a surge of interest in Islamic finance.Now, a slew of academic courses are springing up to meet the demand of those wanting to break into an expanding market. According to ratings agency Moody’s, the global Islamic finance sector is worth $700 billion and has the potential to be worth $4 trillion. More on this story here.

n an effort to curb solid waste pollution, China banned the import of scrap polysilicon at the beginning of August, an effort supported by its current environmental laws according to its Environmental Protection Ministry. Scrap polysilicon is a low-grade form of silicon not pure enough to use in microchips. However, it can be used as a component of solar wafers, which contain a variety of types of silicon, including up to 30% scrap polysilicon. More on this story here.

The energy giant BP and Martek Biosciences, a Maryland based company that uses micro algae to produce oil-based nutritional and dietary supplements, signed a Joint Development Agreement (JDA) earlier this month to produce microbial oils for biofuels applications.

Every once in a while I come across something in the scientific literature that really surprises me.  Because there isn’t much oxygen in a worm gut, it creates the ideal conditions for these particular microbes (”de-nitrifiers”) to turn nitrate (NO3) into nitrogen gas and also generate some nitrous oxide in the process.

Nitrous Oxide

Ok, some background. Nitrous oxide (N2O) is a very potent greenhouse gas with 310 times the global warming potential of carbon dioxide. Its really an Achilles heel for agricultural sustainability because around 80% of the human-generated emissions of this gas come from farms. If even a small amount of the farmer’s nitrogen fertilizer gets converted to N2O it becomes a major part of the total carbon footprint of that field

A far reaching report has called on the aviation industry to drastically increase the use of biofuels, to make a 60% reduction in its greenhouse gas emissions by 2050.

The study, called ‘Green Skies Thinking‘, was published today by right wing think-tank Policy Exchange, and advocates the phase-in of an EU Sustainable Bio-Jet Fuel Blending Mandate by 2020, which would force aviation companies to commit to a rising proportion of jet fuel from sustainable bio-jet fuels.

Crucially, the report also reckons that growing the feedstock needed for advanced biofuels would require significantly less land and be more sustainable than first generation biofuels such as bioethanol and biodiesel, generally used by road transport.

Rubber sidewalks are all grown up.  Once perceived mainly as a safe surface for playgrounds, rubber sidewalks have developed into a means of preserving urban trees, reducing stormwater runoff, recycling tires, and curbing greenhouse gas emissions.  A company called Rubbersidewalks (what else?) began installing the modular units in 2002, and its rubber sidewalk products now appear in almost 100 cities across the country.  Even the U.S. military is getting into the act.  Plans are in the works to install rubber sidewalks at Coast Guard Island in Alameda, California, and they’re being promoted by the Pollution Prevention Program at Aberdeen Proving Ground in Maryland.
