Eh you've just found a way to not feel guilty about your personal pollution.
I don't know what your friend says but I imagine it was along the lines of "it's not your fault! 80% of carbon emissions are due to these 5 oil producers!", conveniently ignoring the fact that it's ordinary people buying the oil...
Still, you can't fix this by hoping people and companies will care. We probably have to force them with laws. So voting is about all you can really do on a global scale.
