Greenpeace activists protest in front of and inside the State Chancellery of North Rhine-Westphalia against dangerous diesel exhaust. The environmental activists deploy a balloon banner that reads: "Diesel makes you sick". Greenpeace activists want to hand over a petition in a hospital bed to Hannelore Kraft (SPD), Prime Minister of North-Rhine Westphalia and ask her to act for a so-called blaue Plakette (blue badge) to get dirty diesel out of affected city districts.
Many cities in North-Rhine Westphalia exceed the limit values for nitrogen oxide. NO2 are mainly caused by diesel motors.
