Beijing has consistently rejected long term goals to reduce emissions. This is because they see it as a threat to its economic growth. The controversy is whether china should be given the autonomy to pursue its route to economic growth, or their process of industrialisation should be halted in order to "go green".
This situation can obviously be regarded from various perspectives. As a TOK student, I believe that a sense of morality cannot be applied to this situation as it will ultimately be a biased opinion.
China is a powerhouse and their economy is clearly not ready to be stopped in order to reduce emissions, and many countries depend on them as well.
