Ira Flatow, NPR: “Replacing dark roofing and pavement with lighter, more reflective materials could reduce temperatures in cities and offset significant quantities of carbon dioxide emissions. In an article published in the journal Climatic Change [Global cooling: increasing world-wide urban albedos to offset CO2 – Hashem Akbari, Surabi Menon and Arthur Rosenfeld
Climatic Change, Volume 94, Numbers 3-4 / June, 2009 – fee only], researchers estimate that replacing 100 square feet of dark colored roof with a white roof could offset about a metric ton of carbon dioxide emissions, in addition to reducing local temperatures and improving local air quality.”
