Accounting rules used for compiling national greenhouse gas inventories play a significant role in constituting the global climate change regime's character. These rules have major political and policy implications. Production-based accounting and national production-based emissions targets contribute to the deadlock in climate negotiations by deflecting attention away from consumption patterns and by accentuating tensions among the climate regime's underlying norms. These dynamics contribute to inefficient domestic mitigation policies, conflict over the norm of “common but differentiated responsibility,” weak international agreements, and continued political neglect of consumption as a driver of emissions. In contrast, consumption-based emissions accounting would shift attention from production to consumption. Consumption-based targets could potentially provide an alternative path by which differentiated responsibility could be implemented. Adoption of consumption-based inventories might also prompt reappraisal of underlying norms and opposing conceptions of justice among states.

Acomprehensive understanding of international environmental politics re quires attention to foreign policy. In this essay we describe a wide range of theories and approaches to foreign policy and international relations, with emphasis on how they can help us to better understand foreign policy in the environmental issue area. We organize the theories into three categories: systemic theories, which emphasize the influence of the international system, including the distribution of power within it; societal theories, which focus our attention on domestic politics and culture; and state-centric theories, which find answers to questions about foreign policy within the structure of the state and the individuals who promulgate and implement foreign policies in the name of a given country. Within this presentation of various theories, we highlight the influence of power, interests and ideas.
