For a number of years, there have been concerns that climate change negotiations will essentially ignore a key principle of climate change negotiation frameworks: the common but differentiated responsibilities. This recognizes that historically:

Industrialized nations have emitted far more greenhouse gas emissions than developing nations (even if some developing nations are only now increasing theirs) enabling a cheaper path to industrialization;

Rich countries therefore face the biggest responsibility and burden for action to address climate change; and

Rich countries therefore must support developing nations adapt to avoid the polluting (i.e. easier and cheaper) path to development—through financing and technology transfer, for example.
