Trucks have a major impact on global warming, the air we breathe, and the safety of pedestrians, cyclists and other road users.

The good news is that the EU is acting and that technology is developing rapidly too. Europe’s first truck CO2 standards were agreed in 2019.
In another first, Europe also agreed a ‘direct vision’ standard for trucks in 2019, along with design changes to enable truck-makers build safer and more aerodynamic cabs.

But much remains to be done.
