Norris got the head of sustainability at Owens-Corning, the giant glass products corporation, to donate three hundred fiberglass blankets for water heaters to the school. In Maine, those blankets can reduce carbon emissions by a significant amount-and save households around seventy dollars a year in utility bills. 10 Houses that get the blankets will share part of their fuel savings with the school, which can use that cash to make improvements at the school and still have plenty left over to buy water blankets to give away to two other schools.
Those two schools will repeat the process, each giving blankets to two other schools, in an ever-expanding sequence. The math of such a geometric progression augurs a ripple effect throughout the region and, potentially, far beyond.
In the first round, every participating school gets credited in its handprint with a reduction of some 130 tons of CO2 emissions per year, for an expected blanket life of at least ten years. But Hand printer also gives it successive credits for every other school in the chain; in just six rounds that should include 128 schools, a carbon reduction of around 16,000 tons of C0 • Assuming new "rounds" every three months, that would be 60,000 tons by the start of the third year, and 1 million by the fourth.
"The LCA calculation for one house's heater wrap starts off negative, when you assess the wrap's supply chain and life cycle," says Norris. "But once you get into the impacts of its use, at a cer tain point it becomes progressively positive for greenhouse gases" as a home draws less power from coal-burning power plants or uses less fuel oil.
Handprints put the negatives (our footprint) in the background and positives in the foreground. When we are motivated by posi tive emotions, what we do feels more meaningful and the urge to act lasts longer. It all stays longer in attention. In contrast, fear of global warming's impacts may get our attention quickly, but once we do one thing and feel a little better, we think we're done.
