What is the objective of your campaign?

The 50by50 campaign seeks to draw attention to the possibilities which existing technologies could bring in improved fuel economy. The campaign shows that we could see a halving in per vehicle CO2 emissions by 2050, thus enabling a massively larger global car fleet to be emitting no extra compared to the base year of 2005, if we pursued those technologies.   It also suggests that whilst the public policy response to this issue may well differ from country to country, and even region to region, everyone must act now to address the issue of fuel economy.
