Countries such as People's Republic of China and India, which were regarded as developing countries at the time of ratification, have economically developed steadily afterward and they have come to produced a massive amount of greenhouse gases to be the world's top-class emitter due to their inefficient energy policies; accordingly, it is problematic that they have not undertaken any obligation in spite of such a situation.
締約当時に開発途上国と見なされた中華人民共和国・インドなどが、その後順調な経済的発展を遂げ、非効率的なエネルギー政策で大量に温室効果ガスを発生させ、世界有数の排出国となっているにも関わらず、何ら義務を負っていないことも問題視されている。
