By your metric ways I see you might not be an American. However, you can readily divide the total motor fuel consumption in the US by the population in the US, and use your figure of energy per liter (which is a bit higher than pertrol, but it doesn't matter).

The point is that the global emissions story boils down to transport fuels, meat, leaky houses, and a long tail of irrelevant things, such as your choice of programming language at small scale.

At large scale the economic incentives alone are enough to encourage huge energy consumers to use a decent language (for example, Google and C++). But the whole information industry taken together is irrelevant to the global emissions story as long as we have an airline industry, cars, and hamburgers.
