How millions of people are fooled by a clique of alleged world improvers. By Harald Kaiser
It's about the number 40. Because 40 micrograms of the gases nitrogen oxide or nitrogen dioxide (NOX / NO2) per cubic meter of air are said to be harmful to health. This is what it has been like to hear, see or read in the war against car emissions for at least three years. Above all, it means the exhaust gas from diesel cars. And because this EU limit value is exceeded more often, especially in city centers, German courts are increasingly imposing driving bans. No matter whether this limit makes sense or is nonsense. Courts do not have to rule on this, they just have to enforce compliance. That is why such judgments are formally okay, because the respective chambers have no choice. Everything else, such as setting the level of such limit values, is a matter for politics.
