Wot are we to do with all this plastic? Turn it back into oil, that's wot.
Talk about taking plastics recycling to a whole 'nother level! And you can do this with a microwave? Sign me up!
Turns out, different frequencies within the microwave range act on specific hyrdocarbon materials, breaking them down into diesel oil and combustible gas.
So, Global Resource Corp (GRC) has built a finely tuned microwave, called the Hawk 10, that uses 1200 different frequencies to zap the material, releasing the hydrocarbon molecules which become gas and oil. Whatever does not have a hydrocarbon base is left behind (via newscientist).

For those who may be new to the ecological footprint game, you may be surprised to discover that downtown Sydney (Australia) has an entire exhibit center for interactive exploration of sustainability issues.
Included in their bag of tasty tricks is this unusually instructive footprinting tool, which can help you figure out what your footprint is now and what actions you might take that could most dramatically reduce your footprint.
To recapitulate, your ecological footprint is calculated from info about your consumption habits, including food consumption, home type, use of resources and waste management, and transportation choices.

Perhaps you've noticed the burgeoning global momentum for adoption of the ecological footprint method in all policy and industry-specific assessments.
It's the best tool we've got for considering all the feedback loops, and Global Footprint is networking vigorously to standardize the methods and data.
I'm pressing for Hawaii to adopt the footprinting method as it launches a new era of research in support of reducing the islands' greenhouse gas emissions.
Meanwhile, Australia in general, and the South Australia government in particular are far down the road toward integrating ecological footprinting and sustainability, as evidenced in their updated Strategic Plan.

OK, so I started this blog to provide quick summaries of significant findings from sustainability science that bear on our discussions about sustainability in Hawaii.
Turns out, the process of synopsizing this 'firehose flow' of new information takes a fair amount of time each day.
So, anytime I stumble on another bloger who's doing similar stuff...and can effectviely lighten this load...I jump for joy.
I'm jumping now, thanks to Costa Samaras, a researcher (and environmental engineering doctoral student) in the Climate Decision Making Center at Carnegie Mellon University.

When we talk about one energy technology being an 'order of magnitude' better than another, we mean it's at least 10 times better.
Since we're looking for emissions reductions in the 90% range, it seems useful to use an order of magnitude as the 'hurdle' rate.
That is, we're most interested in energy technologies that can reduce greenhouse gas (GHG) impacts by an order of magnitude.
Now, new research looks at the entire life cycle of different electricity technologies and confirms that all major renewable tech clears this hurdle (via sustainable research).

Air travel is the elephant in the room as we consider Hawaii's emissions reduction challenges.
Net-net, as Britain is now learning, these air travel emissions could wipeout virtually all emissions reduction gains in other sectors.
Joel Makower reminds us of these essential facts in presenting the latest research on air travel emissions (via 2 steps forward).

Here's another example of how everything's connected. The significant global effort to preserve heritage sites will (obviously) come to naught unless we also mitigate climate change (via bbc).
Wudja believe the glaciers on Mount Everest are at risk?
Campaigning environmental groups, including Greenpeace and the Climate Justice Program, say the UN must take urgent action to protect six World Heritage sites, including Mount Everest, from the impact of climate change. They have been petitioning the global body to list the locations as "in danger".

If you're looking for the sort of comprehensive reforms needed to shift subsidies away from the coal, oil and nuclear industries to investments in home renewable energy and energy efficiency initiatives...don't bother even reading the Senate's energy bill passed last Thursday.
A marginal improvement in energy efficiency standards for appliances in the only bright spot therein.

Whaddya get if your country is shooting to end oil dependency by 2020? "Climate towns", that's what.
Vaxjo is chasing a fossil fuel-free future, and it’s almost halfway there without having sacrificed lifestyle, comfort or economic growth, says Williams.
In the cool forest region of southern Sweden, the city of Vaxjo has turned off the heating oil, even on the darkest, snowbound days of winter. Coal, too, is gone and next on the fossil fuel hit list is petrol.

To get the full impact of this story, first go look at Chip Fletcher's recent presentation on sealevel rise in Hawaii.
Now, consider the fact that the U.S. Centers for Disease Control and Prevention came to the East-West Center (EWC) in Honolulu yesterday to warn delegates at the Pacific Global Health Conference that we are in "the most disaster-prone area in the world" if nothing is done about it (via starbulletin).
Wot's the connection between rising seas and disease, you ask? Let us count the ways:Â Droughts can bring starvation, inundation leads to poor sanitation, hurricanes put pressure on emergency medicine, and disruption can help epidemics spread.

The Hawaii Island ahupuaa poster is, dare I say it, a piece of art. So beautiful, and so...well, big.
Yet, at 28x40 this puppy is still not big enough to totally convey the wonders of this island, and the font sizes had to be scaled down. But, yes, they're perfectly readable...and yes, all the ahupuaa are there.
Whew! Wot a pile of work making sense of the jumble of historically derived boundary lines.

Say you were a huge conglomerate that owned both coal-fired electric power plants and factory farms.
And, say cleaning up your coal emissions was tough, but throwing a tarp over your cows to capture their methane was easy.
Could you use the carbon credits from the latter to offset the former?
Yup, and the Wall Street Journal last Thursday got a good laugh out of this scenario (via worldwatch mag).
Turns out, the American Electric Power Company (AEP), which is one of the largest electric utilities in the United States, spews out more carbon dioxide than any other U.S. company—some 145 million metric tons a year.

While rock star Sheryl Crow recently suggested that people might limit their toilet paper use to address climate change, the reality behind the tissue's consumption is no joke.
Seventh Generation, a Burlington, Vt., manufacturer of recycled paper products and “non-toxic” household products, has a calculation on its Web site suggesting that “if every household in the U.S. replaced just one roll of 500 sheet virgin fiber bathroom tissue with 100% recycled ones, we could save 423,900 trees.”
Here's a tabulation of our comparative per capita annual usage of toilet paper from the July/August issue of World Watch magazine.

Did I mention that our Rotary club's Taste of Hawaii fundraiser went 100% biodegradable with our food service supplies this year?
That's right, spoons and cups from corn plastic, forks from potatoe plastic, and napkins from recycled paper.
Hey, when we're talking nearly 120,000 separate items to feed a crowd of over 3,000, this stuff adds up.
And speaking of earth-friendly napkins, here comes Pablo, the sustainability engineer, with a detailed assessment of earth benefits from using green versus fabric napkins (via triple pundit).

Pinch me again, 'cause I'm seeing headlines in mainstream media that remind me of eco-rants just a few years ago. Then tell me the world hasn't changed...dramatically
Wudja believe just about the biggest deal in food policy globally, the UN's Food and Agriculture Organization (FAO), recently hosted a conference in Rome where a principal agreement was...hold your hats: organic farming is the smartest strategy for food security!
And, wudja believe I picked this up off Schaller's blog (via federal network for sustainability) deep inside Bushtown? Pinch me twice!

Count on about 1% cumulative real costs to California's economy through 2050, says the Electric Power Research Institute (EPRI), which has just released the results of it's detailed analysis.
Perhaps most important, the EPRI study that shows that California CAN achieve its goals of reducing greenhouse gas emissions to 1990 levels by 2020.
OK, so $511 billion sounds like a lot of money...

So, you really, really wanted to fly over to Oahu and attend the climate change confab at the capitol 10 days ago, yet you couldn't justify spewing that much carbon, because you knew there would be lots of up-to-the-minute info on Hawaii's unique challenges, right?
Bruddah, are you in luck! HECO has now posted the presentations from 10 of the 14 speakers at this seminal event.
Read em and reap!
Of particular interest to emissions cappers is John Tantlinger's preliminary estimates of Hawaii's emissions trends since 1990 for the energy and transportation sectors.

Research at two tropical forest sites on the Big Island will be critical in studying the effects of global climate change, officials involved in a new partnership say (via starbulletin).
The Hawaii Experimental Tropical Forest will combine the expertise of the state Division of Forestry and Wildlife, the U.S. Forest Service and the University of Hawaii to take an in-depth look at both dry and wet tropical forests over the next 35 years.
"This will have benefit for all the Hawaiian islands, but also benefits for other Pacific islands and for all tropical ecosystems throughout the world," said Boone Kauffman, director of the Forest Service's Institute of Pacific Island Forestry on the Big Island.

Didja notice that Art Spinella's controversial "Dust to Dust" research into the full footprint of American vehicles has been partially corroborated by Ben Lane's impeccable research into the 'eco-rating' of British vehicles.
Both studies suggest that, yes, improved MPG is generally better for the planet (on this chart of vehicle types, the blue bar MPG declines as the red line e-cost sorta increases). Yet, not always, and not in the case of several high profile vehicles.
Call this the battle of the hybrids against the SUVs. And, at the moment, the score seems to be tied. At least it is no longer safe to assume that hybrids are better.

As promised, here's a quick summary with reference links on the merits of choosing a carbon tax versus a cap-and-trade system.
Bear in mind that the objective is to most effectively and quickly reduce CO2 emissions in the least disruptive or corruptible way.
Upfront, it should be noted that there are no clear winners in this debate, although the taxers are currently gaining momentum while the cappers are waning, due in part to recent reportage on perverse outcomes in the EU's brief track record with cap-and-trade.
The smart money (see RMI and Gore, below) seems to be on a combination of both approaches.
