Correct Answer
10-12%

And here's something for you to take back

There are over a billion cars on the world's roads that are emitting exhaust gases every day, not to mention the emissions from two and three wheelers and buses and trucks.

10-12% of the emissions of these billion plus vehicles will be CO2, that can be quite humungous, don't you think?
