We believe that the findings of this report are highly significant in addressing that challenge. A move across the global fleet towards far better fuel economy at a scale which is already technically achievable, could save over six billion barrels of oil per year by 2050, and cut close to half of CO2 emissions from cars, as well as generate significant local air pollution benefits - and all using existing, cost-effective technologies. This is simply too good to ignore. We have been working in partnership over the past six months to develop the Global Fuel Economy Initia- tive, and are now.
