ABSTRACT
This chapter focuses on two of the most complex, challenging, fully global and multi-sectoral environmental issues inciting the largest and most sustained attention by the G7 leaders since the 1989 Paris Summit-climate change and biodiversity. It also details the commitments made by both Canada and the United States at each of the summits since 1989 in the area of climate change and assesses the degree to which compliance with these commitments has occurred in the ensuing year. A number of the commitments reached at Houston would in fact appear to be a reiteration from the Paris communiqué. The London communiqué made many concrete, identifiable and forward-reaching climate change commitments. Similar to Houston and Paris, the London communiqué reiterated the importance of achieving an effective framework convention on climate change. The empirical findings on climate change commitments suggest considerable support for regime theory and its corresponding institutional variables.
