March Madness causes more than broken dreams and a loss of productivity, The Washington Post reported. Booz Allen Hamilton created an online game that lets users measure the carbon footprint of their predicted winners. It found that Louisville, Mississippi, Davidson and Northwestern State would have yielded the smallest carbon footprint of any outcome, had they all reached the Final Four. Additionally, Indiana, Syracuse, Miami and Marquette added about 140,000 metric tons of carbon dioxide emissions into the atmosphere while traveling to the Sweet 16. That is equal to one year of heat and electricity for 7,147 homes.
