Estimated costs - ??
The proposed OEL for NO2 of 0,5 ppm (8 h) and 1 ppm (15 min) are not impossible to reach but it would require new technology for engines and fuels. With this follows notable costs.
Reliable and standardized measuring methods are key factors to guarantee correct values – Need for new methods
A sufficiently long period of transition is important.
