Road transport : the leader in emission

A research on emissions by transport sector in India had been conducted by T V Ramachandra and Swetmala. Transport sector had emitted 258.1 Terragram of Carbon Dioxide in 2003-04. One Terragram = 1000,000,000 Kg = 1000,000 MT. Hence, the amount of CO2 emitted in a single year by transport sector in 2003-04 was 258,100,000,000 Kg.  The road mode was the major contributor of this emission accounting for 94.5%. While Aviation, Railways and Shipping had emitted 5.5% of CO2 put together.

If we look at statewise emission data, then Maharashtra, Tamilnadu, Gujarat, Uttar Pradesh, Rajasthan and Karnataka had contributed almost half of India’s emission.

There could be multiple conclusions and interpretation of these data. But one conclusion is very clear that we must need to pay attention to road sector on how the emission can be reduced. The key to pollution lies there. Let’s do deliberation and put into action before it becomes too late.
