It sounds simple: If something has a big carbon footprint and you get rid of it, you eliminate those carbon dioxide emissions. Right?

But it’s not always that easy. In a recent study published in The Journal of Industrial Ecology, researchers at the Center for Environmental Strategy at the University of Surrey in England estimated the annual carbon footprint of crime in England and Wales, and found that reducing crime could actually cause society’s overall carbon footprint of society to increase.

The findings illustrated the rebound effect, which describes how reducing the emissions of greenhouse gases in one area can lead to more emissions in the aggregate, because of direct or indirect effects. It’s something that policy makers have often been encouraged to consider when they set out to reduce emissions.
