This is promising:

Eager to pour billions of dollars into clean energy and low-carbon investments, some of the largest institutional investors in the world will urge the U.S. Congress next week to accelerate passage of climate-change legislation that would clarify an investment framework.

Companies such as Merrill Lynch, the $230 (U.S.) billion California Public Employees Retirement System, and Allianz, Europe's largest insurance firm, will demand immediate action by the government, said Adam McDaniel, spokesman for CERES, a national network of investors, environmental organizations and public interest groups.

It's also mentioned in the middle of this (credibly optimistic) New York Times editorial.

That's the largest public pension fund in the U.S. (Calpers is huge -- about $230 billion), the largest insurance firm in Europe (Allianz -- around $130 billion in revenue), and the ... no longer largest anything finance outfit Merrill Lynch. Not too shabby.
