What is your objective, to hold people accountable or to save the planet? Saying that individuals are responsible for the majority of climate emissions is not about shifting blame. Oil companies and bad luck (society picked fossil fuels before we really understood climate change) are to blame, but now we have to switch to damage control mode and that falls on individuals (and the government and corporations, but in a democratic free market society those both wrap back around to individuals anyways). It's just the hand that we have been dealt.
