Green Options

Even as the world prepares for the grand climate meet at Copenhagen this December, a large part of South India has gone under water. And while talks have already begun on coming up with an equitable deal and the very fear that there may be none, over 300 people have already lost their lives while millions are displaced and missing in this global warming related freak weather event, predicted well in advance by the IPCC in its Fourth Assessment Report in 2007.

Mazda, one of the few manufacturers to stay out of the hybrid car craze, has announced they will raise over $1 billion for hybrid research by issuing 315.2 million shares of their stock. As someone who questions the practicality of hybrids, this news is rather disappointing to me personally. You might call me a “hybrid hater.”

But what about hydrogen, Mazda? Le sigh…

Cruise ships lead the pack amongst the world’s top polluters in the transportation industry. If you’re a green-minded person who’s been dreaming of a tropical cruise this winter, but don’t want to lend your support to an industry that is a major polluter, you can reconsider because even cruise lines are trying to go green and do their part to reducing the world’s carbon emissions and overall waste pollution.

I’ve spent a lot of time around the car hobby, and I’ve seen some pretty stupid people do some pretty stupid things. My favorite story involves a V6 Mustang and a leafblower strapped to the air intake, approximating a cobbled together stand-alone supercharger of sorts. Alas, no one ever explained to this man-child that if you add more air, you also need to add more fuel. His engine did not last too long.

But a UK company may be on the right track with an electric supercharger that actually works. Not only does it provide a 40-50% bump in power and torque, but also a 20% decrease in CO2 emissions.

In the midst of a week when climate change finally stole back some of the spotlight that had been hogged by health care reform for months, the Senate fought off a potentially devastating attempt to emasculate the EPA and its recently won power to regulate greenhouse gases.

A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.

As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.

While carbon capture and sequestration technology remains controversial, studies to delve deeper into it are ongoing in hopes of presenting one way to alleviate emission levels. A team from MIT has been studying a carbon capture and sequestration (CCS) technique called pressurized oxy-fuel combustion. This process converts the carbon dioxide emissions of a power plant into a pressurized liquid stream meant to be pumped underground. Team leader Ahmed Ghoniem of MIT claims that his team is the only one conducting an academic study of “pressurized combustion system for carbon dioxide capture.”

Today the Obama Administration released a 1,200 page document of proposed regulation changes that will drastically alter the fuel economy and emissions standards that auto manufacturers are required to meet in the US. Although it could be an incredibly contentious topic, it seems that so far the proposal has gained wide support from all sides of the spectrum including environmental organizations and industry lobby groups.

The changes — which would alter both the Department of Transportation’s and the Environmental Protection Agency’s rules — call for what amounts to about a 5% increase in fuel economy standards per year from 2011 to 2016 starting with 27.3 mpg in 2011 and ending with 35.5 mpg in 2016.

In addition to the new economy standards, the White House has outlined the first ever greenhouse gas emissions limits for new cars sold in the US. Starting with model year 2016, each manufacturer’s new car fleet would have to meet an average limit of 250 grams of carbon emitted per mile driven.

Many commuters have GPS installed in their cars, or have purchased portable devices to try to get them where they’re going. A recent study by NAVTEQ, a data provider for navigation systems has demonstrated that using a GPS device can not only save drivers time spent in traffic, it can also reduce emissions from vehicles by up to 21%.

Yesterday, marking the 100-day countdown to the world-changing climate change conference in Copenhagen, Greenpeace presented beautiful ice sculptures in China and India to “to symbolise the ‘disappearing future‘ for the 1.3 billion people in Asia at risk of water shortage as a result of climate change” and “to show ‘the world washed away’ by glacial melts. They also engaged in several other creative demonstrations around the world to encourage climate action in Copenhagen in December.

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.”
