|Introduction of CNG-Diesel Hybrid Equipment to Public Buses
GHG emission reduction measures : Introduction of CNG-diesel hybrid equipment to public buses with diesel engines enables to replace diesel fuel with CNG, and also enables to improve fuel efficiency of buses, which lead to GHG emission reductions.
Calculation of reference emissions : Reference emissions are emissions from buses without CNG-diesel hybrid equipment which consume diesel fuel only. They are calculated with CNG and diesel fuel consumption by project buses, net calorific value of CNG and diesel fuel, CO2 emission factor of diesel fuel, and fuel efficiency of project bus and reference bus.
Calculation of project emissions : Project emissions are emissions from buses with CNG-diesel hybrid equipment which consume both CNG and diesel fuel. They are calculated with CNG and diesel fuel consumption by project buses, net calorific value of CNG and diesel fuel, and CO2 emission factor of CNG and diesel fuel. Project emissions from fuel consumption by project fuel trucks to carry CNG from the supplier of CNG to the CNG stations are excluded from project emissions since the emissions from fuel trucks to carry diesel fuel in reference scenario are considered to be the same as the ones for CNG in project scenario.
Monitoring parameters : CNG consumption by project buses; Diesel fuel consumption by project buses; Drive distance of project buses
