Global warming is a result of human influence. However, little has been done to stabilize greenhouse gas concentrations in the atmosphere to a ‘safe’ level. An important factor for such dismal state of affairs is that the international community has emphasized far too much on the State-centric approach to combating climate change. The international legal regime does not directly control major emitters or MNCs. This article recognizes the atmosphere as a part of the global commons and the atmospheric absorptive capacity as the common heritage of mankind. Therefore, the international community can pave the way to link global climate change regime and MNCs. Those common interests of the international community can be protected when MNCs turn their production processes green, by redirecting their investment into green technology, and try to alter the negative status quo.
