White Roofs Could Reduce Global Warming
At the Global Climate Change Conference recently, scientists from the Lawrence Berkeley National Laboratory presented a plan that could offset 44 gigatonnes of atmospheric carbon dioxide. The study insists that if people whitewashed or painted their roofs white, this action would reflect more solar radiation, thus reducing global warming while saving money on air conditioning bills. White-topping the roof of an average family home is like sucking 10 tons of carbon dioxide out of the air and it also cuts energy costs by 20 percent. If major cities in tropical and temperate zones adopted paler roofs and pavements, it could offset 44 gigatonnes’ worth of atmospheric carbon dioxide. That’s more than the world emits in a year.
