Deutsche Bank Climate Change Advisors is one of the leading climate change investors in the world. From my perspective, however, the key role they play is as a word of reason from the business side of the ledger. There are so many old-line businesses: industry, banking, manufacturing, etc., that are often pushing against taking strong action on climate change. DBCCA is the opposite.
As a business in the investment industry, they need to be as knowledgeable and insightful and accurate as possible if they intend to succeed in the long run. They have identified climate change as a "mega-trend." From their site:
In the last two years, DBCCA has put out about two dozen investment reports that provide key insights into how climate change interacts with investing and business in general. These reports are well researched and thorough and make strong cases for action on climate as well as taking more in-depth looks at particular industries and trends. Some recent examples include:
Natural Gas and Renewables: A Secure Low Carbon Future Energy Plan for the United States
Climate Change: Addressing the Major Skeptic Arguments
(I particularly like this one for its thorough look at debunking the skeptic arguments. In my opinion, this paper is more influential than many due to its source from a major investment player rather than an advocacy group.)

I receive an email when new research comes out from DBCCA. I was not able to find a place on their web site where you can sign up. If you are interested, though, try sending an email to Bruce Kahn, and he will put you on his list.
