Investors and companies are increasingly aware that climate change and its associated needs for reducing CO2 emissions are likely to impact structurally many areas of the economy. This paper offers a contribution to understand these impacts on companies’ strategy, by studying management systems. A typology is introduced based upon a two stage model. At stage one, the firm becomes aware of the risk and CO2 is a compliance issue. At stage two, the firm is involved in a more global re-assessment of its business portfolio including its relationship with suppliers and clients. The construction is based on three case studies: DuPont (chemicals), Lafarge (building materials) and Unilever (consumer goods). The implications of the analysis for investors are drawn.
