21 percent of homes account for 50 percent of greenhouse gas emissions

Energy conservation in a small number of households could go a long way to reducing greenhouse gas emissions, scientists are reporting. Their study, which measured differences in energy demands at the household level, appears in the ACS journal Environmental Science & Technology.

Dominik Saner and colleagues point out that the energy people use to power their homes and to satisfy their mobility needs accounts for more than 70 percent of emissions of carbon dioxide, the main greenhouse gas involved in global climate change. To cope with that problem, policymakers and environmentalists have focused largely on the supply side, for instance, electric power plants, heating systems and cars that release carbon dioxide into the atmosphere. Saner and his team decided to take a close look at the other end of the equation—how energy consumption for housing and land-based mobility at the household level impacts .

Their study of more than 3,000 households in a Swiss town found that only 21 percent of the households accounted for almost 50 percent of greenhouse gas emissions. The biggest factors contributing to a few families having a disproportionately large environmental footprint were large living spaces (which use energy for heating, lighting and cooling) and long commutes in private vehicles. "If their emissions could be halved, the total emissions of the community would be reduced by 25 percent," the scientists concluded.

Tell it to Al Gore - his footprint is big and heavy.

nein sense, as usual, has no sense.

Why do I think he'd enjoy landing a "big and heavy" footprint on your posterior? Could it be a history of misleading, unconstructive troll posts?

Vicar Gore burns over 20 times the power of the average US household and despite this, AGW cultists would kiss his posterior.

One wearies of your constant pecking at one aspect of a subject like an insane woodpecker looking for a grub in a block of concrete.

You lack the humour to be entertaining, the knowledge to be informative, and have all the charm and attraction of a deceased rat which suffered from leprosy and incontinence.

What kind of sick mind would produce a statement like the above. What's even more disturbing is that the cult takes delight in it.

What a dessicated mind you must have to fail to appreciate its artistic qualities.
