Not a fan of your color map. Because you used a diverging color map, the least saturated colors, near 50%, isn't some intuitive reference value such as 0, and look too much like NA. You should have used a sequential color map.

I tried that and I would tend to agree with you that in principle a sequential color map would be the preferrable choice. However the big advantage that a diverging scale gives, is that the extremes in either direction are highlighted which I think gives more immediate insight for this kind of data. You can immediately see which countries have not reduced their emission yet, but also which countries have reduced their emission a lot.

With a sequential map only one of the extremes would stand out.
