Focusing on the top 20%

Even if every house on your street looks the same, there's a good chance they're emitting vastly different amounts of pollution, according to a new study published by Environmental Science and Technology.

Researchers found that 21% of the households in the investigated region were responsible for 50% of the total greenhouse gas emissions. If those homes cut their emissions in half, the total emissions for the whole community would be reduced by 25%.
