A group of institutional investors, who say the collectively represent about 100 million Exxon shares, want Exxon Mobil director Michael Boskin removed and will withold support for his reappointment because he has failed to take action on climate strategy, Dallas Business Journal reports.

The investors, which include the California State Teachers Retirement System, the New York State Common Retirement Fund and more than a dozen others, say Boskin has refused five times since late 2005 to meet about the issue.

Exxon Mobil says senior management has invested substantial time and resources over the past year addressing the concerns and that Boskin has personally responded in writing.

The announcement came the same day as Exxon Mobil released its 2006 Corporate Citizenship Report.
