The word "emission" literally means "discharging". This term is commonly used in finance and physics, but the greatest popularity of emissions has been gained through the link with ecology. In this case, it is mainly the discharge of harmful substances from different sources into the atmosphere. The most common emission engineers are classic gasoline cars or factories that emit harmful particles from chimneys. In today's developed countries, an emission limit is normally set, which can not be exceeded. Emissions are calculated in mg / hr / month / year.
