Mostly, what you are seeing is that the half of the world living in the India-SEA-China circle [1] are living much better lives, which requires far more energy then living as subsistence farmers did. In the G7, CO2 emissions have declined (but not as fast as they need to stay below the 2C target) but the rest of the world is emitting more: during the negotiations for the Kyoto Accords in 1998 G7 countries produced about half of the world's CO2 and now they produce about a quarter. That's mostly because the rest of the world started emitting more and only a little because of drops in the amount produced by G7 countries.

There is obviously major ethical issues here. The rich, already developed world- having emitted enormous quantities of CO2 to get there- telling poor, undeveloped people living as subsistence farmers that they can't use any more energy because of all the CO2 already in the atmosphere is a really hard argument to make, locking them into being poor forever while the developed world benefits from all that CO2 consumption. But on the other hand, by skipping right to large scale solar, maybe those inside the circle can do a better job?
