We draw on NGO and market research, and corporate and investor activity. The focus is on establishing a framework for analysis and assessing how investors and corporations are responding in terms of risk management, disclosure, corporate capital expenditures and the implications for investors in terms of portfolio management, engagement and divestment. This is done in the context of share and commodity markets. We show that carbon asset risk (CAR) is in the process of moving from discussion and acknowledgement to action and impact.
