A few days ago, the European Commission presented its Green Deal, which aims to make the EU climate neutral by 2050 in order to protect the environment and improve people's health and quality of life. One of the planned measures is the introduction of stricter exhaust regulations. The limit values for pollutant emissions from vehicles have already been laid down by law. The current target value is 6x1011 particles per kilometer (Euro 6d-Temp), but only particulate matter bigger than 23 nanometer... PHYS.ORG · 1 month
