Green-leaning Britons are exploiting peer pressure to curb global warming.
Across the country, individuals are pledging their commitment to low-carbon lifestyles by joining Carbon Rationing Action Groups, or CRAGs.
The “craggers,” as they are known, calculate their personal carbon emissions from home energy bills, car emissions and airplane travel and then agree to limit their emissions to an amount set by the CRAG. Although each CRAG sets its own rules, in some groups, members who exceed their personal limit pay a fine which may then be donated to climate action nonprofits. Those who progressively limit their emissions each year can earn money from less frugal members, who pay into the group.
