Not all homes pollute equally—even in the relatively homogeneous world of a mid-sized town in Switzerland. A study of a village of 3,000 finds that 21 percent of households belched half the town’s greenhouse gases. The biggest factors running up the carbon tabs of the disproportionate polluters: the size of their houses and the length of their commutes. Airline travel wasn’t factored into this research.

The energy people use to power their homes and drive their lives accounts for more than 70 percent of CO2 emissions, write the authors in  Environmental Science & Technology. But in addressing that problem policymakers and environmentalists mostly point their fingers at the supply side: power plants, heating and cooling systems, and the fuel efficiency of cars. The Swiss researchers chose to parse it differently and developed a lifecycle assessment model of how energy consumption for housing and car travel, per household and per capita, impacts greenhouse gas emissions.

Their conclusion: ?energy conservation in a small number of households could go a long way to reducing greenhouse gas emissions. If the super polluting homes cut their emissions in half, the authors write, “the total emissions of the community would be reduced by 25 percent.”

Be interesting to see the model these researchers developed used to compare the larger income and lifestyle gaps typical in US towns and cities.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
