1999] COMMON BUT DIFFERENTIATED RESPONSIBILITY 29
(e.g., Antarctica and the deep seabed) and resources (e.g.,
whales) as “common interests” of humankind.

Bearing in mind
that humans depend on a healthy climate for their survival, the
General Assembly went further by recognizing the earth’s cli-
mate as a “common concern” of humankind.
12
This implicates
not only the need for international cooperation to protect human
interests, but also a “certain higher status inasmuch as it empha-
sizes the potential dangers underlying the problem of global
warming and ozone depletion [and suggests] that international
governance regarding those ‘concerns’ is not only necessary or
desired but rather essential for the survival of humankind.”
13
Insofar as the climate is of such crucial “common concern”
to humankind, it follows that there is a responsibility on the part
of countries to protect it. This begs the question of who is re-
sponsible for climate pollution. The answer is a function of each
country’s historical responsibility for the problem, its level of
economic development, and its capability to act. This was sug-
gested by Principle 23 of the 1972 Stockholm Declaration, which
states that it is essential to consider “the extent of the applicabil-
ity of standards which are valid for the most advanced countries
but which may be inappropriate and of unwarranted social cost
for developing countries.”

The CBDR principle is described succinctly in Principle 7 of
the Rio Declaration on Environment and Development:
