5.4.2 POTENTIAL CO₂ SAVINGS

An extensive analysis was conducted in order to estimate the potential annual green- house gas savings by substituting 5% of total diesel fuel consumption with CNG in the CEE region. The expected results for both methodologies can be seen in Figures 5.8 and 5.9.

Figure 5.9: GHG – 5% substitution of diesel fuel by CNG, DLR & Partners’ methodology

The results show a greenhouse gas reduction of 3.8% using the JEC methodology, which represents 477 thousand tons of CO ²  eq . When the DLR & Partners’ method- ology is employed, an even more significant GHG reduction of 11.8% is achieved, corresponding to 1,511 thousand tons of CO ²  eq . This figure incorporates not only passenger cars but also buses, which represent heavy-duty vehicles. As described above, an even more significant reduction can be reached by blending CNG with biomethane.
