I'd expect developing countries to massive increase emissions first as they capitalize. Reason why PRC uses more concrete in 3 years than US uses in last 100 apart from PRC being massive is because US/west emissions from capital/construction (30% of total) is spread out over time. All the developing countries are going to be pouring tons of concrete as they grow. Some emissions can be mitigated from production end but a lot of the dirtier stuff is unavoidable.
