Then there's is no progress to be made. Developing using cheap energy regardless of emissions, i.e. the harm/ethics (positives) of poverty reduction > pollution any day. US/west sets the baseline for historic not just annual per capita emission - annual doesn't capture historic emissions for building infra/capita base. Many countries still have magnitude more steel to smelt and concrete to pour. If developing / low middle income countries does most of the growing/developing on clean generation, better, if west wants to subsidize that like prior climate pledges, they're welcome to. Until then, their per capita is floor of what everyone should aim for. Ultimately, global emissions isn't really worth worrying, as in even if it's existential for some tiny islands or climate death zones, there's shit all do because most of the world who desires to be rich and comfortable will just chug along.
