Résumé : Firms are key actors interfering with the negotiations of international environmental agreements. However, their ability to engage in collective lobbying via the establishment of business transnational coalitions has received little attention so far. In order to fill this gap, this article conducts a micro–macro analysis of corporate lobbying during the negotiations of two sub-agreements of the Convention on Biological Diversity. In particular, it scrutinises the degree of transnationalisation of two senior business lobby coalitions in these negotiations: the Global Industry Coalition and the International Chamber of Commerce. In contrast to former studies of business lobbying on environmental agreements, the analysis stresses the variety of business interests represented in international negotiations and underlines the bargaining processes taking place inside each transnational business coalition. Transnational business lobby coalitions are found useful for business networking activities, either as tactical tools or as information platforms. Yet corporate lobbying efforts are still conducted predominantly on an individual basis.
