Business has become a key part of the fabric of global environmental governance, considered here as the network which orders and regulates economic activity and its impacts. We argue that businesses generally are willing to undertake limited measures consistent with a fragmented and weak policy regime. Further, the actions of businesses act to create, shape and preserve that compromised regime. We examine three types of indicators of business responses in North America: ratings by external organizations, commitments regarding emissions, and joint political action. We find business response to be highly ambiguous, with energetic efforts yielding few results.
