Tiguan HyMotion Fuel Cell Concept Car

Last Thursday I had the opportunity to attend a VW press event showing off the new hydrogen fuel cell powered Tiguan. The vehicle (above) is one of only two concept prototypes in the world, and this one was flown in from Germany for its US debut.

The event was originally intended to be a test-drive of the HyMotion Tiguan, but the vehicle was having “electrical problems” that kept it out for display only. A VW spokesperson assured us that it had nothing to do with the fuel cell, but whatever the problem was they didn’t want it to happen to us in mid-day San Francisco traffic.

There are more than 5,000,000 heavy duty trucks running up and down US highways each day. Every one of those trucks gets an average of 7 mpg, carries upwards of 200-300 gallons of diesel, and spews out potentially harmful emissions.

Like it or not, we depend on them to bring us our food, fuel, and products for everyday living. It’s a connection that most of us often forget about, only remembering it long enough to curse them as they slow us down on the highway.

It’s also an industry that has recently been hit hard by soaring fuel prices, and now, with the average price of diesel in the US at $4.70/gallon and climbing, it’s sure to get worse.

Needless to say, there’s a rising cacophony of voices within the trucking industry clamoring for relief. Most of this noise currently comes in the form of wanting a break in fuel prices, but really that’s just a temporary fix. Any solution with sticking power would have to offer both economic and environmental benefit — you know, win-win.

New diesels will get better mileage and have cleaner emissions than your average car. Pictured above: 2009 Jetta SportWagen 2L TDI Clean Diesel.

Later this year (see the timeline below), we will finally begin to see an influx of new model diesels in the United States. While diesels make up 50% of the market share of vehicles in Europe, they’re still trying to shrug off the stigma of being dirty, noisy beasts here in the US. So what changed?

VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx

VW’s ultra-low emission 2009 Jetta will be coming to the US mid-summer, according to an announcement made late last month at the Vienna Motor Symposium.

This newer version of the Jetta will meet the strictest emissions standards in the world—BIN5/LEV2—which are enforced by 5 US states: California, Massachusetts, Maine, New York, and Vermont. BIN5/LEV2 standards severely cap nitrogen oxide (NOx) emissions (0.05 g/mile), one of the two tailpipe pollutants that have given diesels a bad rap (that and particulate matter).

Clean Burning Natural Gas Vehicles (NGVs) are hot commodities in some parts of the country, where fuel can sell for as low as $0.63 per gallon.

Unlike the world’s most fuel efficient car (VW’s 285 MPG bullet), the Honda Civic GX looks like a standard passenger vehicle. What makes it special is what you don’t see: tailpipe emissions that are often cleaner than ambient air.

The Civic GX is powered by compressed natural gas—methane—the simplest and cleanest-burning hydrocarbon available. With an economical 113-hp, 1.8-Liter engine, the EPA has called the Civic the “world’s cleanest internal-combustion vehicle” with 90% cleaner emissions than the average gasoline-powered car on the road in 2004.

And get this: in Utah, natural gas can be purchased for $0.63 per gallon.

The effort to help change the world’s polluting ways is a long road that was never going to be solved overnight. However, with the help of LiveScience.com, maybe we can effectively destroy any hope of it overnight.

I call this story “How to Successfully Undermine Good Ideas” thanks to a recent article written over at LiveScience.com entitled “Top 10 Craziest Environmental Ideas.” And, in short, several of their “zany ideas” are possible chances for survival.

When you think of Americans who have done a lot for Climate Change, current president George W. Bush doesn’t spring to mind. The guy he beat for the current spot, Al Gore, definitely springs to mind; I like to think of GBW as the anti-Gore.

Over the past week rumors and rumblings about a climate plan underway in the current and fading Whitehouse have emerged. Thankfully, it all seems a bit “disappointing.”

Seventeen nations have come together in Paris for two days in the latest round of climate warming talks, under the heading of the Major Emitters Meeting. The South African delegation was the one to label Bush’s proposals – to halt a rise in U.S. greenhouse gas emissions by 2025 – as disappointing. “There is no way whatever that we can agree to what the U.S. is proposing,” South African Environmental Affairs Minister Marthinus van Schalkwyk said in a statement.

Every now and again I like to return to a topic I’ve already touched on before (please don’t ask me to find where I did, the archives confuse me). So when my news feeds pointed me towards this new research, I couldn’t help but head back to another ‘no-brainer’ for you all.

To be published online in the open access journal Carbon Balance and Management, new research shows that, while planting trees alone may not be the only solution to solving our climate problems, planting new forests or managing existing forests or agricultural land could help us in the long term.

How? By encouraging the land to work as the natural carbon sink it has been for so long. \

As I walked around last year’s Kitchen and Bath Industry Show in Las Vegas, I asked where I could find the green products. I was encouraged to put on my walking shoes and make the trek to a minor hall where I found about twenty square feet devoted to five or six products that left little impression on me. Much has changed, it seems, in only one year. Green is the buzzword at this year’s show, helped in no small part by the host city, Chicago, showing off its green-ness through LEED building projects going up within sight of the convention center. Just about every booth displayed information on how green their products were. “Green building has become the spark that has added some life to this industry,” a representative from MasterBrand Cabinets told me.

Water saving innovators Kohler and TOTO made green the focus of their booths, proudly displaying the Watersense stickers on their high efficiency toilets. TOTO, who recycles 100% of their china, has developed a universal toilet bowl whose tank can be interchanged from a 1.6 gallon per flush to a 1.28 gpf e-tank.

Most of us are at least vaguely familiar with biodiesel, but how much do we really know?

While biodiesel is easily the most popular alternative fuel available, it’s commonly misunderstood or misrepresented by inaccurate information. Since the most frequent question I get is, “So what exactly is biodiesel, anyway?“, I decided to write a tome covering all the basics—a one stop shop for all your biodiesel- related questions.

It’s been exactly one year since I published the first Biodiesel Mythbuster on GreenOptions.com, and its popularity made a sequel inevitable. By way of a short introduction, here’s what I wrote last year:

Straight up, I’ll say that the heading is supposed to be “alarmist.” But the fact remains that, unless we do something now, the future is far too unpredictable to depend upon.

A report published in Nature by authors Roger Pielke Jr., Tom Wigley and Christopher Green, has described the IPCC’s assumptions that the bulk of the challenge of reducing future emissions will occur in the absence of climate policies as “…optimistic at best and unachievable at worst…”
