Mansley, Mark. "Risking Shareholder Value? ExxonMobil and Climate Change." Claros, May 2002.

Studies the effects of global climate change on the valuation of ExxonMobil, and argues that the company is taking an unnecessary risk with its high-profile opposition to policies intended to control global warming. Assesses the risks to ExxonMobil's market capitalization at over $100 billion (through reputational risk, litigation risk, risks from sudden policy changes, and missed opportunities), but does not provide a detailed analysis of how these numbers were calculated.
