A map below displays which nations pollute the most disproportionately for their level of consumption and production.
<1x nations have especially effective industries and the best regulatory standards. While the >1x nations are below-par.
For example, Ulaanbaatar (Mongolia) is the coldest capital city in the world and many of the pastoral nomads live in yurts. So to stay warm they burn large quantities of coal because they don’t have any other option.
<1x nations are more likely to have service-oriented economies and produce fewer emissions for their level of production, while the >1x countries are more likely to be industrial-based. But the service-oriented economy often, importing the emission-related stuff from abroad (for example from China) thus “not contributing” or just being poor without many industries.
