There are some potential solutions to reduce these emissions, but so far its still theoretical

since the industrial revolution we have not only invented a lot of things but also identified certain harmful policies, and with inventions and policies-to-avoid in mind, countries can develop with a lot less emissions than current western countries did, and most likely with a higher quality of life per amount of emissions

for example, in terms of harmful-policies-to-avoid, we learned that subsidising a vegan diet and eliminating car dependency in urban planning not only eliminates a ton of emissions, but also increases quality of life; these two things can be easily incorporated into spending/planning policies of any country without any additional investment or technological breakthroughs

electricity generation using solar panes and wind turbines is now cheaper than conventional electricity generation with fossil fuels, so developing countries can to a large degree avoid relying on the latter, but this does require some investment and technological innovation in order to happen (something western nations could help with)

there’s also probably a lot of other similar aspects which would be easily optimized but that i don’t know about

so all in all, there are certainly unavoidable emissions that come with development and quality of life improvements, but developing countries can avoid a lot of these emissions with either no/little investment and technological improvements
