The best way to reduce fuel emissions is to use public transport. So, instead of driving to work, maybe you can take a bus or the metro. You can also try pooling with a couple of your co-workers that live in the same area. We also think, Shuttl is a great app and transport service to avail. Other little things you can do is maybe always take an Uber pool, rather than Go.
You can ride a Shuttl bus for approximately INR 80 per trip.
