Response to Heavy Duty Vehicles CO2 emission standards

18 Jul 2018

Dear Mr/Mrs, I have a question regarding the following document: ANNEXES: to the Proposal for a regulation of the European Parliament and of the Council setting CO2 emission performance standards for new heavy-duty vehicles Section 2.3: Calculation of the zero- and low-emission factor as referred to in Article 5 The equation to calculate ZLEV is given as follows: ZLEV = V/(Vconv + Vzlev). Suppose I have a fleet consisting of V=1000 vehicles, from which Vconv=900, and Vzlev=100. The 100 vehicles (Vzlev) are low-emission vehicles with a CO2v of 175g/km. Applying the equation for ZLEV leads to: ZLEV = V/(Vconv + Vzlev) = 1000/(900 + 100*(1 - 175/350)) = 1000/(900+50) = 1.0526 Since ZLEV is used to calculate the average specific CO2 emissions (section 2.7), I would assume that ZLEV should be a number between 0.97 (minumum allowed) and 1.0. Any number above 1.0 penalizes the usage of ZLEV vehicles, such as in the case of the previous example. Could you please review the above calculation and explain why a number above 1.0 is possible?
