Et andet vigtigt emne på COP 5 var udviklingslandenes frivillige forpligtelser, og det er anbefalelsesværdigt, at udviklingslande såsom Argentina og Kasakhstan tager initiativ til at reducere deres egne emissioner af drivhusgasser.
Another important feature at COP 5 concerned the voluntary commitments of developing countries and it is commendable that developing countries such as Argentina and Kazakhstan are taking the initiative to reduce their own greenhouse gas emissions.
