Common but differential responsibility:
i. Common but differentiated responsibility means that every country has to work for protecting environment but more responsibility **** on developed countries.
ii. This argument was accepted in the Rio Summit in 1992.
iii. The developed countries of the North want to discuss the environmental issue as it stands now and want everyone to be equally responsible for ecological conservation.
iv. However the developing countries of the South say that much of the ecological degradation in the world is the product of industrial development undertaken by the developed countries.
v. If they have caused more degradation, they must also take more responsibility for undoing the damage now.
vi. States shall cooperate in the spirit for ecological protection
