MNCs are increasingly facing global environmental issues demanding coordinated market and non-market strategic responses. The home country institutional context and individual company histories can create divergent pressures on strategy for MNCs based in different countries; however, the location of MNCs in global industries and their participation in 'global issues arenas' create issue-level fields within which strategic convergence might also be expected. This paper analyzes the responses of oil MNCs to climate change and finds that local context influenced initial corporate reactions, but that convergent pressures predominate as the issue matures.
