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.

Although in 2011 Japan finally decided not to participate in the second commitment period of the Kyoto Protocol to the United Nations Framework Convention on Climate Change, under the principles of sustainable development and common but differentiated responsibilities, it has probed the ways in which the ‘ultimate objective’ of the UNFCCC will be realized in the international community. With regard to socalled ‘emissions trading,’ since the middle of the 2000s, Japan has continuously adopted various methods and approaches for domestic emissions trading at local and central government levels. This article analyzes Japan’s recent efforts in introducing emissions trading schemes and finally refers to the Joint Crediting Mechanism, which covers the period until a future new agreement under the UNFCCC comes into effect.

Climate change is an emerging environmental issue. To prevent possible trade sanctions from the industrialized trading partners, Taiwan proposed several policies to mitigate greenhouse gas emissions. This includes their preparation of the Greenhouse Gas Reduction Act is under legislature review and the Statute for Renewable Energy Management. Because Taiwan is not a member of the United Nations, it is excluded from participation in the United Nation Convention on Climate Change and lacks access to the flexible mechanisms defined under the Kyoto Protocol. The Taiwan Environment Protection Administration plans to encourage the local emitters to acquire foreign reduction credits to offset domestic emissions. This article approaches Taiwan’s mitigation policies and measures from an international legal perspective. It also introduces adaptation policies and recommends that the government establish a special national adaptation team to prepare data and criteria for risk prioritization. Finally, this paper recommends that the Parties of the UNFCCC adopt the ‘universal apply’principle for climate change and allow any governmental agency whose governing matters are covered by the convention, to participate and share emission-reduction responsibilities.

This paper examines the early operation of the Kyoto Protocol’s non-compliance procedure since 2006. Several important non-compliance cases recently or currently before the Kyoto Compliance Committee of the procedures and mechanisms deserve to be analysed and discussed. As we may see, the enforcement branch of the Compliance Committee has dealt with some important cases of non-compliance; Among them, from the viewpoint of interpretation or application of international environmental treaties, the question of compliance by Croatia would be particularly interesting. What must be noticed is that the Kyoto Protocol’s NCP has prepared a multilateral forum which enables both the parties and the enforcement branch to base their arguments on international legal perspectives. This examination will also contribute to contested theories of compliance with international legal rules.
