You're looking at absolute numbers. CO2 usage used to be accelerating rapidly. The first step to reducing the absolute number is to change the second derivative, the acceleration. We've done that, the second derivative of that graph is significantly negative. Once the area under the curve of the second derivative is negative enough, the first derivative, the velocity, will go negative. We're about there, the year on year change is now about zero. Once the first derivative is negative the absolute number starts dropping.

So yes, more than nothing has been done to reduce emissions, but you need to look at the right numbers and graphs.
