Years after everyone else, GM and Toyota execs skeptical about hydrogen cars

That Saturday Night Live-esque headline was inspired by a story in The Wall Street Journal yesterday:

Top executives from General Motors Corp. and Toyota Motor Corp. Tuesday expressed doubts about the viability of hydrogen fuel cells for mass-market production in the near term and suggested their companies are now betting that electric cars will prove to be a better way to reduce fuel consumption and cut tailpipe emissions on a large scale.

Really? Hydrogen cars of dubious viability? Who ever could have guessed that in a million years? And electric cars are "a better way to reduce fuel consumption and cut tailpipe emissions on a large scale"? I'm shocked, shocked that anyone could come to that conclusion.

Bank of America can’t make the call in green buildings

Bank of America says that energy-efficient windows in its newer buildings are blocking cell-phone signals.

If deals go through, three firms will own 90 percent of the U.S. beef market

In Meat Wagon, we round up the latest outrages from the meat and livestock industries. You’d be hard-pressed to find an industry more consolidated than beef-packing. Just four companies slaughter 83.5 percent of cows consumed in the United States. In standard antitrust theory, a market stops being competive when the four biggest players control 40 […]

New survey of U.K. youth reveals mixed attitudes about the future of the planet

Ben Tuxworth, communications director at Forum for the Future, writes a monthly column for Gristmill on sustainability in the U.K. and Europe.

Debates about how we should save the planet tend to explore the impossibility of almost every approach until someone says, "We need to change the education system," at which point it is deemed churlish to snigger. Catch 'em young, and it's job done seems to be the hope. Well, with only 100 months of planet-saving time left, according to Greenpeace, this approach has worked as much as it is ever likely to. So, are the young going to save us?

Fresh perspective comes from the Future Leaders Survey, a scan of 25,000 applicants to U.K. universities and colleges published last month. The survey, carried out by Forum for the Future and UCAS (the central admissions service for higher education in the U.K.), paints a picture of young Brits facing a fairly terrifying future with an odd mixture of denial, irritation, and pragmatism.

New company wants to seed ocean with iron to sequester carbon

Weeks after ocean-seeding company Planktos bit the iron dust, a startup called Climos is plowing ahead with a similar business plan: seed the ocean with iron dust to stimulate the growth of CO2-gobbling plankton, then sell offsets for the sequestered carbon. Climos has announced $3.5 million in venture capital and is backed by reputable investors: […]

Federal loan program for coal-fired power plants suspended amid climate, cost concerns

A federal loan program for coal-fired power plants in rural areas has been suspended due to concerns over climate change and the costs of the program. The Rural Utilities Service, part of the U.S. Department of Agriculture, issued $1.3 billion in loans to coal plants since 2001 under the program. However, RUS officials said costs […]

Volkswagen’s new entry to the clean diesel fleet

Enough election talk, it's time to put some honest-to-goodness car news in the Gristmill (so this one's for you, JMG!).

Volkswagen is about to unveil a new Golf hybrid, said to feature an all-electric mode at low speed and regenerative braking to compete with the Prius and its ilk. The difference is that this is a diesel-electric hybrid, which VW says will get 69 mpg and exceed Europe's (and California's) tough emissions standards.

The point is somewhat moot, as this internal-combusion-perpetuating monster will not be for sale in the U.S. But is this just another indicator that clean diesel cars are greener than hybrids?

Perhaps. But filling one of these new Golfs with locally produced, organic, fair-trade biodiesel made from waste vegetable oil by a worker-owned biorefinery will certainly help.

Company creates global map of wind patterns

Any way the wind blows, weather-consulting service 3Tier wants to map it. The company has created a global map of weather patterns that’s available free on the internet, allowing anyone to check whether there’s strong enough air movement — and transmission capacity — to power property in a certain area. 3Tier plans to do a […]

EPA attempt to ban bird-killing pesticide runs into opposition

The U.S. EPA has proposed a ban on a pesticide lethal to birds, but is running into resistance from the company that produces the chemical. The pesticide, carbofuran, is typically used on crops such as corn, alfalfa, and potatoes, and has been linked to the dieoff of 558 separate bird flocks since 1972. A manager […]

Can we trust carbon labeling?

About a year ago, I was cautiously bullish on British supermarket giant Tesco's pledge to start putting carbon labels on its food. But I think that their progress so far -- which I'll get to in a minute -- suggests an important lesson about the policy risks of treating a fuzzy exercise as if it were completely reliable.

Tesco's idea was that the chain and its suppliers would pay for objective, comprehensive reviews of the greenhouse-gas emissions from the foods on the store's shelves. The analyses would cover all major steps in bringing food from farms to the checkout line -- everything from running farm machinery, to food processing, to transportation, to refrigeration. Then, each item in the store would be labeled with the climate-warming emissions that could be traced to that particular product.

This sort of exercise is called "life cycle analysis," and it's been used for decades to great effect, to shed light on all sorts of questions: paper vs. plastic (for bags), cloth vs. disposable (for diapers), hybrids vs. hydrogen (for cars), and a host of others.

Last week, a nifty article by Michael Specter in The New Yorker reported on Tesco's progress so far. The results? There's still only one product on the shelves with a carbon label -- a single brand of potato chips, or "crisps" in British parlance.

You see, as it turns out, life cycle analysis can be really, really difficult. And to make matters worse, it may be that the whole enterprise is chock full of uncertainty.

Where carbon is concerned, it can be hard to trust the label.
