MIT professor of mechanical engineering Timothy Gutowski recently had his students compare the energy consumption of different people in different socio-economic classes, from a homeless person to a senator. In total, 18 different lifestyles were chosen ranging from vegetarian students to pro-golfers to a five-year-old.
What the researchers at MIT found was that even in the U.S. people with the lowest energy usage, a homeless person, a five-year-old and a Buddhist monk, all have a carbon footprint twice as large as the average global citizen. This is because the services provided for every American, including infrastructure and public services, guarantee set a baseline that no American can drop below.
The carbon footprint of the low energy consumers were about one-third the American average. Americans are big foots when it comes to their carbon footprint. The world average is four tons; Americans on average consume 20 tons.
Bill Gates, specifically chosen for the study, has a carbon footprint about 10,000 times the average. Of course, he also has produced a great deal of wealth and growth for the world. In general, the researchers found that as income rises, so do emissions. A homeless person, who ate at soup kitchens and slept in shelters, had an average carbon footprint of 8.5 tonnes, still twice as much as the world average. Even monks, who lived half the year in the forest, had carbon footprints of 10.5 tonnes.
But the big question of how to lower carbon footprints is a tough answer. The study found that voluntary reductions is likely unobtainable for the average American. Considerably more can be done by the wealthy, but the best way to lower footprints is to tax carbon use which, Professor Gutowski says, is a hard pill to swallow, especially for politicians.

Carbon emissions and pollution are not the same thing... Trees produce Carbon Dioxide at night.. does that mean trees are bad and we should cut them all down to reduce baron emission?? of course not.. because Carbon emissions are just too overly simplified a view of pollution... the public seems to love it... but it is just incorrect and inaccurate way of looking at pollution.
Then to bring in homeless people and talk about what all Americans have is a joke... most large cities still have laws on the books that try to make just being homeless a crime... homeless do not enjoy the benefits that they are supposed to have on paper... society does not treat them the same.... even if it legally should... U.S. society simply does not.
By the reasoning of that study... the Average U.S. Black Bear pollutes more than the average world citizen just because it lives in the U.S....
Grrrerrr.

That study is a joke. It brings into question the values of this site too. I am forming the opinion that this site is just a honeypot to attract people of a 'green demographic' for advertising.

While it certainly is not enjoyable to have close to nothing and struggle for survival, I hope our society transforms its values and ends tolerating those who live above and beyond. Don't know how - don't know when, but we need a value revolution and turn away from what is considered desirable by most Americans.

Practical Advice to Pollute Less

Oh! Oh! Suddenly the tables have turned, and the homeless is in fact the less sustainable wretch!
Seriously, pay attention to the ratios. Just because Google uses more juice to power its data centers than any other search engine doesn't mean they're bad. Per gigabyte of traffic, they may in fact require less kwh, placing them in the lead. Same goes for this.

And you morons are going to continue to spout this non-sense, regardless of how wrong you will be proven to be about it.
There is only one solution for the likes of you vermin.

1. encourage ingenuity to develop less polluting and more efficient technologies, etc.
2. it would responsibly penalize those who pollute more compared to those who pollute less.
3. would it not (along with the Cap & Trade mechanism) work to quickly reduce overall inefficiencies?
From what I know, yes, it might initially impact productivity and performance of those countries that don't like it; but we're looking here to solve a global issue (one that doesn't respect territorial boundaries (except one, the vacuum of space and the "bubble" of our atmosphere).
As for people like us (I am assuming you're meaning people who believe in fixing those problems which either we have or have been enacted upon us), whom you seem to call vermin; what did we do to you?

Of course rich people have a greater climate impact than poor people - they consume more. Of course North Americans have a greater climate impact than the global average - the energy embodied in our infrastructure is huge. These are not scandalous, counter-intuitive notions. They make complete sense, and denying them out of some sort of righteous indignation at being "blamed" helps no one.
As for the last comment, I'd be very interested to hear your thoughtful rationale for why a carbon tax is such a terrible solution. And then I'd be happy to debunk said rationale.

Relative to other environmentalist measures, elemental rebalancing seems to me a mere distraction. Why don't we start rebalancing our consumption of iron to fit natural and exact stoichiometric ratios? Count every little atom and lose sight of the real reason why we're doing creative accounting!

Also, trees emit co2 at night, but oxygen by day, and the total balance is evident in the mass of the tree, which is mostly carbon. So the tree *is* the carbon it has absorbed.
and mr. green people are vermin, go kill yourself and do the planet a favor.

The universal measurement among all fossil fuels, both those used for electricity and transpo, is CO2. So for accounting purposes, it makes sense for this to be the metric. And just in case human-induced global warming is real (it is), we might be able to solve that, too. So pick your reason. Call it whatever you want. Fossil fuels have to be taxed. If carbon had been taxed since the '90s, we would have depressed demand a long time ago, developed more efficient vehicles, and wouldn't be in the current oil crisis.
We might have more electric cars, which are both more efficient and can run on secure, domestically produced energy...even if much of that currently comes from coal. It's still more efficient as an energy source (cheaper and less CO2), even with a carbon tax, and it doesn't require a war to secure.
