Umbra on the other greenhouse gases

Dear Umbra, I have heard and am beginning to understand one of the biggest movements of social change occurring right now: we need to reduce our carbon footprint. I have also heard that while carbon is our most abundant greenhouse gas byproduct (by way of the burning of fossil fuels) other gases, such as methane, […]

Umbra on water softeners

Dear Umbra, I live in an area that has fairly hard water. The calcium build-up on the sink faucets, shower enclosures, and even the dog water bowls is really bad, and hard to remove. So I have considered a full house water softener. However, I know nothing about them — but I do know you […]

What is the most unsustainable piece of junk you own?

An unusually unsustainable device that I own (see below).

I'm hoping to expand on the Ponzi scheme discussion in my next Salon piece. So I'm gathering examples of unsustainability at every scale.

In asking what is the most unsustainable piece of crap junk you own, I wasn't really thinking private jet or Hummer, not that I think any of you own that uber-unsustainable stuff.

Nor was I thinking of an electric dryer, since most people (in this country) own that laborsaving device. But that does get us closer to the key question, though: How many of the 10 billion people on the planet post-2050 will be using large amounts of electricity for things that are easily done without electricity -- once we have moved beyond desperation and are actually in the midst of the climate catastrophe.

By junk I was thinking of something closer to a relatively superfluous device that symbolizes the Ponzi scheme we have created. What comes to mind at the moderate cost level is a leaf blower and even a Segway (sorry, Dean Kamen -- your genius is really needed urgently for sustainability, not for electrifying human walking, even if many people find some value in that). I don't own either of those, but I do own a treadmill and a 50-inch flat panel TV (but hey it is Energy Star), which are close to what I have in mind in this post.

And I'd also be interested in hearing about any of the truly pointless low-cost stuff you have, like an electric pencil sharpener. Indeed, what really got me thinking about all this yesterday was my use of a gadget (pictured above) whose pointlessness and unsustainability simply staggers the imagination:

The NYT asks: are we shaming our politicians about their lifestyles enough?

Eager to find new ways to trivialize the warming of the planet, the New York Times has been reporting on the carbon footprint of individual politicians and legislatures.

They are abetted in this effort by Terra Eco, a French environmental magazine that has calculated British Prime Minister Gordon Brown's footprint to be -- quelle horreur! -- 8,400 tons of CO2 per year. By my calcs, that's about 0.0001 percent of America's carbon footprint, so as soon as Brown buys a bicycle, we should have the climate problem pretty well licked.

In the meantime, I applaud Terra Eco's work on this important issue, and look forward to their upcoming report on the size of Al Gore's swimming pool.

Umbra on beer and wine

Hi Umbra, Due to, among other things, (organic) beer, I ended up in a rather heated discussion on the environment the other day. I’m wondering if you could help clear up a couple of these more or less classic micro-level questions. Which is more environmentally friendly: lighting a cigarette with a match or a lighter? […]

Greenpeace assesses the carbon footprint of Obama’s stimulus plan

The Obama administration’s original stimulus proposal would reduce greenhouse-gas emissions by at least 61 million tons per year, according to an analysis commissioned by Greenpeace from the consulting firm ICF International. (Here’s the summary report and highlights.) The report estimates that reductions resulting from the Obama plan would be equivalent to eliminating the emissions of […]

Umbra on gift cards

Dear Umbra, I received a gift card this holiday season from a friend to a company which I generally avoid due to its subpar eco-practices. Since my friend has already given the money to this company, do I forgo my moral objections and use the card, or is there another way I can make the […]

Do the emissions from a single Google search matter?

Apparently the question of how much greenhouse gas emissions can be traced to a single Google search is the hottest topic on the internets.

Research from U.S. physicist Alex Wissner-Gross says a single search produces 7g of CO2. Google says, nuh uh, it only produces 0.2g CO2 -- less than your personal computer generates while running it. Lots more here.

There may be some value in drawing attention to the substantial carbon footprint of the IT industry, but by the time this kind of thing gets filtered through the media it ends up yet another story about how every human action is a source of guilt and shame. Now they want us to search Google less?

In fact, the emissions of Google searches is a goofy distraction. As Joe notes, the internet has been a phenomenal driver of energy efficiency and dematerialization. Imagine how much clueless driving around has been eliminated by Google Maps!

Umbra on biodiesel vs. hybrids

Dear Umbra, I live in Massachusetts and am trying to decide whether to buy a hybrid or a biodiesel. Since it is cold here, I would need to use 20 percent biodiesel and 80 percent diesel in the winter. How does this compare with a hybrid’s emissions? Which would be better for the environment? Tom […]
