Yeah, this is true.

From the actual report:

The richest 10% (around 630 million people) accounted for 46% of the total emissions growth – only marginally less than the 49% contributed by the middle 40%. The poorest 50% barely increased their consumption emissions at all.

Adding up the top 10 countries’ populations doesn’t even reach 630 million.

People will probably use this to say that the top 10% need to pay for taxes and be held accountable, without realizing they’re probably in that 10%.

I’d actually like to see the 10% broken down even further.
