"...which could reduce global CO2 emissions by 14 million tons!" Nice article, but how much exactly is 14 million tons? I mean, what are the overall emissions of CO2 by aircrafts? 50 trillions? 50,000 trillions? We really have a lot of problems communicating with the general public. I remember seeing a big banner the other day in the MC boasting that the WB has spent about $750 million fighting malaria since 2005. Well, that's basically 8 days of sales for a company like Coca-Cola. We are never going to be able to communicate anything unless we start putting things in perspective and focus on tangible impacts rather than on huge vague numbers.
