700 college students and the Clinton Global Initiative in New Orleans for spring break
Commitments to start social-change initiatives and spirited discussions of global issues -- these aren't typical results of 700 college students heading to New Orleans during spring break season. But last weekend, students from a diverse group of colleges, several dozen university presidents, and prominent social change agents -- not to mention Bill Clinton -- spent a day and a half on Tulane University's campus for Clinton Global Initiative University (with a cameo by Brad Pitt).Trying to live-blog an event while you're also trying to finish your senior thesis -- not a good idea. Nonetheless, a belated report from the Clinton Global Initiative's new youth event:

NYT offers special section on green biz
The Sierra Club is embarking on its first product endorsement, putting its logo on Clorox’s new Green Works cleaning products. Various businesses are aiming to bypass carbon neutrality and move straight on into carbon negativity. These and more stories show up in a New York Times “Business of Green” section Wednesday, which covers the green-biz […]

What investments should be made with carbon tax revenue?
Monica Prasad had an op-ed in The New York Times yesterday called "On Carbon: Tax, Don’t Spend." It’s … peculiar. This basic pitch: "if reducing emissions is the goal, then a carbon tax is a tax you want to impose but never collect." That is to say, per the headline, you Don’t Spend the tax […]

Proposed land swap would allow drilling in Alaska wildlife refuge
Photo: usgs.gov The U.S. Fish and Wildlife Service is considering a land swap with a Native-owned energy company that would open up about 200,000 acres of Yukon Flats National Wildlife Refuge in eastern Alaska to oil and gas drilling. Under the pending deal, the energy company would trade about 150,000 acres of its nearby land […]

California board to vote on requiring fewer zero-emission vehicles
On Thursday, the California Air Resources Board will vote on whether to require fewer zero-emissions vehicles on the state’s roads in coming years. As it stands now, automakers must sell 25,000 zero-emission vehicles by 2014 and an additional 50,000 by 2017. Under the proposed changes, the numbers would drop to 2,500 by 2014 and 25,000 […]

Since when is regulation optimal?
I like Jeffrey Sachs, and I generally agree with what he has to say about poverty, health, and the obligations of the rich to look after the poor. But he gets it dead wrong in the current Scientific American:
Even with a cutback in wasteful energy spending, our current technologies cannot support both a decline in carbon dioxide emissions and an expanding global economy.
Says who? Why can't we find ways to dramatically lower our primary energy use per dollar of GDP? Not because we're already so perfectly balanced. And not because the electric industry (amounting to 40 percent of U.S. GHG emissions) has done a damn thing to increase their energy efficiency in the last 50 years.
Even if every industrial facility in the country had optimally designed their factories for energy efficiency (they didn't), we still would need to confront this reality: an optimal capital allocation when natural gas was $3/MMBtu, coal was $1/MMBtu, oil was $20/bbl, and electricity was 6 cents/kWh looks pretty suboptimal when natural gas is up to $10, coal is pushing $3, oil is north of $100, and electric is running towards 9 cents.
Yes, technology is good. But we have to get beyond the idea that regulation is optimal, all capital is optimally deployed, and there are no significant opportunities for energy efficiency.

A factor of 3.67 makes a big difference when discussing climate
The biggest source of confusion and errors in climate discussions probably concerns "carbon" versus "carbon dioxide." I was reminded of this last week when I saw an analysis done for a major environmental group that confused the two and hence was wrong by a large factor (3.67). The paragraph I usually include in my writing:
Some people use carbon rather than carbon dioxide as a metric. The fraction of carbon in carbon dioxide is the ratio of their weights. The atomic weight of carbon is 12 atomic mass units, while the weight of carbon dioxide is 44, because it includes two oxygen atoms that each weigh 16. So, to switch from one to the other, use the formula: One ton of carbon equals 44/12 = 11/3 = 3.67 tons of carbon dioxide. Thus 11 tons of carbon dioxide equals 3 tons of carbon, and a price of $30 per ton of carbon dioxide equals a price of $110 per ton of carbon.

Not looking good for ice shelf in the Antarctic
While the area of collapse involves 160 square miles at present, a large part of the 5,000-square-mile Wilkins Ice Shelf is now supported only by a narrow strip of ice between two islands, said CU-Boulder's Ted Scambos, lead scientist at NSIDC. "If there is a little bit more retreat, this last 'ice buttress' could collapse and we'd likely lose about half the total ice shelf area in the next few years."

Bon Jovi to offset next tour
Photo: Stephen Lovekin/WireImage. Remember back in 2006, when Jon Bon Jovi said he got into green stuff to offset his hair spray-related indiscretions in the past? Allow me to remind you: Actual quote: “Do you really want to know why I’m doing all this goodwill? … It’s because I feel guilty about the huge hole […]
