P a g e | 72 So, NOx contaminations from human activities have two critical impacts – regional air quality and climate change. For the transportation sector, it is act locally to act globally (Figures 41 | 42) : Figure 41 – Atmosphere Radiative Forcing (RF) from Road Transportation Source: United Nations IPCC Some still may be confused by the indirect nature of NOx and GHG accumulations and hence incorrectly overlook it.
