  • EPA provides only some documents related to California waiver

    The U.S. EPA has given Sen. Barbara Boxer (D) only some documents related to the agency’s refusal to allow California to regulate car greenhouse-gas emissions — not all, as she had asked. Missing or redacted documents include a presentation said to predict that EPA would lose if sued over its recalcitrance (which, of course, it […]

  • There are limits to the positive environmental change we can expect from high gas prices

    You can scarcely pick up a paper or turn on the television these days without hearing the word recession. Leading economic indicators have wiggled in different directions over the past few months, but the general trend appears to be negative. The conventional wisdom points toward an economic downturn of some kind during 2008, and businesses […]

  • The latest in a string of endorsements for Obama from red-state Dems

    Rep. Rick Boucher (D-Va.), notorious champion of Big Coal, has endorsed Barack Obama. Some greens are no doubt going to use this as evidence that Obama is too close to coal. I share the concern, but I don’t think it’s the most sensible interpretation of this case. Boucher’s endorsement is just the latest in a […]

  • Conservationists highlight weirdness of rare amphibians in push to save them

    Roughly 20 percent of the 100 most imperiled amphibians haven't been seen for years.

  • Where will biofuels and biomass feedstocks come from?

    When it comes to biofuels we have choices. We can do it poorly, using short-run approaches with no potential to scale, poor trajectory, and adverse environmental impact. Or we can do it right, with sustainable, long-term solutions that can meet both our biofuel needs and our environmental needs.

    We do need strong regulation to ensure against land-use abuses. I have suggested that each cellulosic facility be individually certified with a LEEDS-like "CLAW" rating, and that countries which allow environmentally sensitive lands to be encroached be disqualified from CLAW-rated fuel markets.

    We think a good fuel has to meet the CLAW requirements:

    C -- COST below gasoline
    L -- low to no additional LAND use; benefits for using degraded land to restore biodiversity and organic material
    A -- AIR quality improvements, i.e. low carbon emissions
    W -- limited WATER use.

    Cellulosic ethanol (and cellulosic biofuels at large) can meet these requirements.

    Environmentally, cellulosic ethanol can reduce emissions on a per-mile driven basis by 75-85% with limited water usage for process and feedstock, as illustrated later. Range, Coskata, and others currently have small-scale pilots projecting 75% less water use than corn ethanol, with energy in/out ratio between 7-10 EROI (though we consider this a less important variable than carbon emissions per mile driven).

    Sustainable land use

    The question about biomass production that arises first is about land use: how much will we need? What will it take? Is it scalable? For conservatism, I assume CAFE standards in the U.S. per current law, though I expect by 2030 to have much higher CAFE and fleet standards (hopefully up near 54mpg or a 100% higher that 2007 averages), which will dramatically reduce the need for fuel an hence biomass. Yes, this would include lighter vehicles, more efficient engines, better aerodynamics, low-cost hybrids, and whatever else we can get the consumer to buy that increases mpg.

  • Livestock registration, pitched by feds as voluntary, is creeping toward mandatory

    You have read, in this space among many others, of the sinister nature of genetic modification and the patenting of seeds. I have ranted endlessly about the dangers of the food system being in the hands of just a few corporate land barons.

    No reason to stop now.

    For about five years now the USDA and many large corporate interests have been pushing a program called the National Animal Identification System. NAIS is touted as an effective tool in battling the spread of livestock diseases such as cattle tuberculosis and bovine spongiform encephalopathy, commonly known as mad cow. It provides methods for tagging livestock of any kind with RFID, the same sort of microchip that many people have put on their pets in hopes of recovering poor Fido if he ever gets lost. The thinking is that if a side of beef in a Greeley, Colorado meatpacking plant tests positive for mad cow, authorities can quickly and easily identify said cow, trace it back through the system, and discover other animals with which it may have made contact.

    Currently, at the federal level, NAIS is a voluntary program overseen by the USDA and administered by the several states with help from organizations like the Future Farmers of America and the Farm Bureau. Farms, feedlots, and confined animal feeding operations apply for and receive a formal numerical designation that is then applied to microchips injected into or ear-tagged onto each animal. According to the USDA, in 2007 the state of Iowa went from 11,000 registered sites to more than 20,000, an increase of over 80 percent -- all this despite a lack of any sort of government funding to participants for the program. Farmers must buy in if they choose to participate.

    Setting aside for the moment that this system feels like a perfect bureaucratic method for closing the barn doors after the mad cows get out, all this seems fairly innocuous until we look a little deeper. The state of Texas has recently passed legislation requiring NAIS tagging for all dairy cattle. It goes into effect March 31. Wisconsin, Michigan, Virginia, and Tennessee now require participation for goats and sheep. In Michigan, farmer and now reluctant revolutionary Greg Niewendorp has endured visits from the sheriff reminiscent of scenes from and old Billy Jack movie.

  • Decelerating growth in tropical forest trees, thanks to accelerating carbon dioxide

    I meant to blog on this earlier, but lost track of it after failing to find the original study (for reasons that will become clear). The bottom line is:

    Global warming could cut the rate at which trees in tropical rainforests grow by as much as half, a new study based on more two decades of data from forests in Panama and Malaysia shows.

    The effects, so far largely overlooked by climate modelers, Nature magazine said, could severely erode or even remove the ability of tropical rainforests to remove carbon dioxide from the air as they grow.

    More evidence that the carbon sinks in the ocean and on the land may saturate sooner than scientists expected, which will inevitably lead to an acceleration of atmospheric concentrations of carbon dioxide (see below).

  • Study quantifies ecological debt owed to world’s poorest countries

    New research has attempted to quantify the costs that richer and poorer nations inflict on each other through environmental degradation. And guess who gets dumped on more? Turns out, the poorest countries have endured more environmental strife from richer countries than the other way ’round. The study, published in the journal Proceedings of the National […]

  • An alternative housing concept

    Seattle is having a cold snap. It's 25 degrees outside. Our rare freezing winter days correspond with equally rare clear winter skies. Days like this make me wish I had a solar powered home that could harvest and store that free burst of energy for later use.

    The bottom line is that American homes are just too large to be cost effectively heated with solar energy. The push has been to get the cost of solar panels down. But, what would you get if you crossed an expensive solar heating and cooling system with an optimally sized home? By optimal, I mean not larger than you need. You would get an affordable solar powered home like the one shown above (click here to see the details).

    By affordable, I mean in the $150-200 thousand range excluding land, sewer, and water systems. Picture the north face with fancy wood and slate trim, a deck off of the loft doubling as a carport, double french doors, and lots and lots of windows (and window plugs). Essentially, this is a well insulated 10 x 40-foot park model trailer stocked with highly energy efficiency dual mode gas/electric appliances, and lots of diode lighting under a standardized solar energy system optimized for a given area of the country. Picture an entire neighborhood (or trailer park or commune) of these all facing south. Ninety percent of the people on this planet would jump at the chance to live in a home like that. Home size is relative, dependent on wealth and how far the "my house is bigger than yours" arms race has progressed. It's all a matter of perception.

  • At Dem debate, candidates agree on green jobs, fight over everything else

    Photo: AP/Mary Ann Chastain At the acrimonious Democratic presidential debate on Monday night, the three leading candidates bickered over a whole range of issues, but they all agreed on one thing: the need to invest in creating green-collar jobs. The CNN moderators didn’t ask any questions about the environment, but Hillary Clinton, John Edwards, and […]
