Ladies and gentleman, boys and girls… come right in for another edition of the Greenest Show on the Web: the Carnival of the Green! Fresh off of a stellar performance at Ms. Malaprop, the Carnival’s here at Green Options this week to amaze and delight you. But don’t wait around — the show has a limited engagement here, and then it’s moving on for a stint with our friends at Greener Magazine.

What’s the Carnival of the Green (or COTG, as we green bloggers like to call it)? It’s a roundup of some of the best posts on green blogs from the past week. Always moving, the COTG stops for a visit on a green blog every Monday. The Carnival was the brainchild of Al Tepper, publisher extraordinaire at City Hippy, and Nick Aster, the man behind (and often in front) of the curtain at Triplepundit. These days, our friends at Treehugger play tour manager for the Carnival.

Now that we’ve got the formalities out of the way, let’s get on with the show. And if you’re suffering from a case of the Mondays, here’s a little music to put you in that carnival mood…. wherever you are.

The Hall of Science

Come on in, and take a gander at the latest technological wonders. Won’t cost you a dime…

We’ve got a double-header from EcoGeek this week. Want some help adjusting your driving to save fuel? Hank and co. take a look at the Fuel Mizer, which can monitor your stops and starts for you. And if you’re a walker (which we hope you are!), two students at MIT are just won a prize to harvest the energy from your footsteps (yep, we covered that one, too).

The Naib, over at The Sietch, investigates the Watercone, a device that uses solar energy to desalinate water. This piece of simple technology could do a lot of good for people without easy access to fresh water.

For the Dedicated Followers of Fashion…

We’ve got some Fall previews, and some new looks.

The Natural Collection is predicting an ethical Autumn as they roll out their Fall fashions online. Keep an eye on their site, as they promise "some fantastic giveaways, competitions and freebies" are on the way.

Nature Mom Tiffany Washko takes a look at some furnishings (particularly beds) that are both green and stylish.

Inhabitat shows us how designer Stephan Boltz gives a second life (and new sense of style) to airplane trolleys.

And speaking of reuse, our own Victoria E. shows us how the Broken Plate Pendant Co. turns "useless" china into unique pieces of jewelry (on her own blog).

The Carnival’s Trade Show

Catch the latest trends in green business and finance.

Sox First has a podcast interview with Erik Mather, managing director of Regnan, on the growing pressure for companies "…to come clean on their contingent liabilities that include environmental, sustainability and governance risks."

Great Green Gadgets expresses some skepticism about carbon offsets, particularly those involving tree planting. Doesn’t mean they’re against planting trees, though… even guerrilla style!

And the Savvy Vegetarian shares a post from market gardener Jocelyn Engman on the importance of supporting local farmers.

Time for a Break… and a Beer

All this carnivaling can make you thirsty…

GO’s Gavin Hudson shares some tips on making your own eco-friendly brew: cheers!

And the Green Cougar points to that inevitable post-college dilemma for green grads: aluminum cans or glass bottles?

The Medicine Show

Health and safety stories with a green tint.

Allie’s Answers takes note of some of the potential dangers presented by manufactured nanoparticles in sunscreens.

The Environmental Working Group’s Enviroblog presents a video on the danger that still exist from arsenic-treated lumber used for decks and playsets.

Finally, at sustainablog (my other blog), I took a look at an editorial in the Minneapolis-St. Paul Star-Tribune claiming that greener development of transportation infrastructure could create less wear and tear on roads and bridges (so they’re less likely collapse!).

Get a Glimpse of Far-Away Lands…

A couple of our participants in the Carnival this week share some travel information and experiences.

Intelligent Travel spotlights several green hotels you might want to consider on your next getaway.

Sally Kneidel of Veggie Revolution recounts her visit (complete with some great photos) to the South African village of Welverdiend

The Souvenir Stand

If you must buy, make sure it’s sustainable.

The Millionaire Mommy Next Door claims that "Memories are made of the things we do, not the things we buy." We couldn’t agree more!

La Marguerite reminices on times past when we didn’t throw away so much stuff.

And Green LA Girl takes a look at some eco-friendly claims made by some companies about their products, and shows that a little digging often chips the green gilding off of these fairly ordinary items.

Finally, Take a Stroll Down the Midway…

You never know what you may find.

INNside Innkeeping in Montana highlights efforts by Xanterra Parks and Resorts, the owner of hotels and restaurants inside a number of state and national parks, to green up their own operations. That’s right… Yellowstone is going green…

Maria Energia, the blog of our own Maria Surma Manka, considers the implications of recently-announced renewable energy deals by BP.

Jetson Green takes a look at an ancient case of urban sprawl, and wonders if it provides some insight into more recent calamities such as post-Katrina flooding in New Orleans, and the bridge collapse in Minnesota.

In another post, Intelligent Travel offers its congratulations to Java Green, a D.C.-area cafe’ that recently won the title of "Best Vegetarian Restaurant" in a contest held by VegDC.

Flower-Garden-Bulbs.com provides some tips for getting flower bulbs started right… the organic way.

The Good Human muses upon the messages sent by environmentalists concerning climate change, and claims that the planet itself will survive this crisis; the human species, on the other hand, may not be so fortunate.

And, finally, our good friends at Lighter Footstep help spread the word on the October 15th Blog Action Day, when a diverse array of bloggers, ranging from Lifehacker to ProBlogger, will be writing about, and raising funds for, environmental issues.

That’s a wrap, folks — thank you for coming by and enjoying the Carnival. We’ll see you next week at Greener Magazine!

Thursday morning’s session at the Papandreou Foundation’s Symi Symposium focused on the "green economy": how to craft economic policy that both internalizes the costs of a carbon-based economy, and creates incentives to move away from carbon-intensive energy sources. The presenters in this session were Joseph Stiglitz, professor of economics at Columbia University and former member of the Clinton administration, and Angelo Consoli, Director, Codeco s.s., European Affairs and Progressive Communication.

Professor Stiglitz’s presentation picked up on a theme that has run throughout the conference: the question of the best economic mechanisms to address climate change. Stiglitz argued (as have others) that a carbon tax is preferable to a cap and trade system (the model embraced by the Kyoto treaty, and much of the business world). Because changes in the market away from fossil fuels will inevitably make those energy sources less expensive, carbon taxes keep their prices high, reflecting the costs imposed on society by carbon emissions. Stiglitz also argued that such taxation responds to another reality: market-based approaches won’t work by itself, and government investments in infrastructure, research, and preparedness will be needed to round out a comprehensive approach to fighting climate change.

Other costs that the developed world likely will face stems from advancing the concepts of energy security and independence. If countries like China and India act in accordance with these concepts, that inevitably means that they’ll be burning more coal — China is already building coal-fired power plants at the rate of one/week. This could be disastrous in terms of climate change, but it points to the need for developing countries to build their energy infrastructure. If countries like China and India have to impede their own development to play a part in a global response to the climate crisis, Stiglitz argued that they should probably be compensated.

All of these question are important for the next round of climate negotiations. Stiglitz noted that in order to bring the developing world into this process, measuring carbon emissions on a per capita basis will be critical, as will a strict enforcement system. His last point: trade sanctions will likely be the most effective means of enforcing adherence to carbon mitigation strategies adopted by the international community.

Consoli’s presentation dealt with a completely different issue: the necessity (his argument) of developing the hydrogen economy in order to address global warming. He argued that one of the major impediments facing the growth of renewable generation technologies is storage, and that by using renewables such as wind and solar power to electrolyze water and create hydrogen, we can overcome that impediment. Consoli noted that the development of such systems, which would be decentralized, also has the benefit of empowering (in every sense of the word) people around the globe without access to electricity, or the capital to create it with current centralized generation technologies. The economic effect of such a transition involves a move from carbon-intensive energy sources, which require high amounts capital, to renewable sources that require high amounts of labor, so renewable production of hydrogen as an energy storage mechanism ends up boosting employment and economic growth.

Consoli presented the EU Parliament’s Written Declaration on energy, and it’s five pillars:

• Efficiency
• Renewables
• CO2 Reduction
• Hydrogen
• Smart Grids

As you might imagine, the questions and responses came quickly and furiously to these presentations, and included thoughts about the political reality of carbon taxation, the idea that such taxes create a right to pollute, the problem of hydrogen generation from "dirty" sources, and the methods by which governments can encourage their citizens to accept changes that could be painful in the short term. As usual, I’m giving a quick and dirty overview here — feel free to ask questions or offer your own responses.
