Todd Thompson, former Citigroup CFO and one-time CEO of its Global Wealth Management Division, is supposedly raising a $3 billion cleantech-focused private-equity fund, according to VentureBeat.

Thompson was reportedly raising $1 to $2 billion for a new private-equity fund last year. But the fund, which was originally slated for other purposes, is now focused on cleantech and carbon-credit companies, according to the blog.

In January of last year, Thomson was ousted from his job during a Citigroup management shakeup.
