You cannot solve a puzzle by picking out one piece. You solve a puzzle by looking at all the pieces and not stylising yourself as the moral hero and assuming that everyone else will follow. That is short-sighted thinking.
A per capita figure may play a role in politics in negotiations, but it is not relevant for solving the problem.
It is like accusing a Norwegian living in a fjord of wasting water. For example, it is completely irrelevant how high the per capita consumption of an Icelander is. Or a Greenlander. Because it doesn't solve the problem.
Yes, the US has a higher consumption. But it's just 334 million inhabitants vs 1,440 million in China (which still puts America in the top five, but far behind China).
If you really want to solve the problem then you need to develop a practical solution for China.
But let me ask you a question: Let's imagine that everything is suddenly perfect in your country. The economy has suffered brutally because of all the changes, but you are now the world leader in CO2 per capita consumption. What do you think happens then?
