Europeans don't monkey around when it comes to cigarette warning labels. Large print, simple messages, and impossible to avoid. Apparently, vehicle advertisements need to be a little more clear about the dangers the vehicle poses to the pocketbook and the environment.
Car ads that references a specific make and model, according to EU directive 1999/94/EC, which passed in December 1999, need to reveal fuel use and CO2 emissions in way that is easy to read and prominent and "be easy to understand even on superficial contact." While some car advertisements in the EU and UK have come under fire for being misleading (see examples by Toyota and Lexus and Hummer), a researcher at a Belgian university found that almost every single car ad (99 percent) in the EU is illegal.
Examples of what car ads should look like and ways to voice your concern are available at this site, which was set up by ten environmental and greener car groups, including Greenpeace and the Alliance Against Urban 4x4s (4x4 is the British way of saying SUV).
