Boston looks to generate electricity from indoor composting

The city of Boston is looking to build an urban, indoor composting facility. Most cities, if they compost at all, transport food and yard waste in gas-guzzling trucks to dumps outside the city limits, where energy and methane from decomposing biomass get lost to the atmosphere. The first-of-its-kind proposed Boston facility would generate electricity from […]

National Hanging Out Day on April 19

Here's a great way to mark Earth Day next month. Each year, the grassroots group Project Laundry List promotes the very picturesque observance of National Hanging Out Day, both to raise awareness about the enormous energy benefits of air-drying laundry and also to draw attention to the fact that, amazingly, this practice is severely restricted in many places around the U.S., especially green ol' California, where 35,000 homeowners' associations have banned the practice.

But electric dryers are inefficient and expensive to run, so the "right to dry" is becoming a new rallying cry around the land. PLL is pushing legislation in a number of states, including its home state of New Hampshire, where the measure recently failed.

So on April 19, consider a colorful clothesline display, plus info from PLL's site to enlighten and amuse. A lot hangs in the balance, you might say.

Water problem? What water problem?

There’s no water problem. Dean Kamen solved it: More details here.

Americans want to spend on green, but can’t figure out how, says study

Americans are primed to spend up to $104 billion on “green” technologies this year — but don’t know where to find them, says a new study. Which seems crazy, considering the plethora of green-shopping websites and companies joining in on the “green revolution,” but what do we know? According to the survey conducted by Rockbridge […]

Carbon policy is close to getting the macro right, but plenty of smaller decisions remain

My recent exchange with Gar has made it clear that there is a wide gulf between those details of carbon policy that are theoretically optimal and those which actually impact carbon reductions. Or, to be blunt, those that come up in our weekly staff meetings as actually affecting our decision to consider potential carbon reduction projects and those which simply elicit groans around the conference room of the "great intent, why did they screw up the execution?" variety.*

From our perspective, the good news is that our policy does finally appear to be moving not only toward putting a price on CO2 emissions, but getting the really important details (like auction vs. allocation) right. The bad news is that most of the other details are still wrong.

Umbra on trash bags

Dear Umbra, I am attempting to wean myself off plastic bags. I am also aware of the environmental impact of brown paper bags. So we are OK with cloth grocery bags, but can you suggest an alternative that can be used as a trash can liner (that’s economical)? Lisa Columbus, Ga. Dearest Lisa, Plastic trash […]

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 […]
