They only have a ridiculously small environmental footprint until they end up moving to the 1st world. And they aren't moving to consume less. Immigration is pegged as a matter of policy to boost consumption, and increase wealth for the wealthy. The fertility rate in the 1st world is stagnant - immigration is the reason the population grows. Emissions rise because of demand, and for the past 20 years, that demand has been a result of rising economies (e.g. China), and to a lesser extent growth in the Western world (through immigration). Emissions will keep rising until that quells. Fortunately, it's projected to in 100 years or so, but ending that sooner is possible and warranted. We can achieve this with universal access to contraceptives, and by lifting countries out of poverty more rapidly.
