correct me if I’m wrong: I think CNG taxis
are still more environmentally friendy than euro 4 or 5 diesel
taxis as I find that less exhaust fumes are emitted from
CNG taxis. I think its time to import more
environmentally friendy vehicles, and not limited to taxis only, as
I find the roads nowadays are quite polluted. Also, our govt should
discourage the use of old vehicles and introduce regulations to get
them scrapped asap, as they generally are very pollutive and emit
lots of smelly and harmful smoke.
