Embattled city Comptroller John Liu has delivered a $16.56 million contract to the former vice president�s environmentally friendly investment firm, Generation Investment Management, to help manage hundreds of millions of dollars in city pension funds, The Post has learned.

The Comptroller�s Office had previously awarded Gore�s firm $12.8 million in pension-fund business under Liu�s predecessor, Bill Thompson.

Since 2009, state Comptroller Tom DiNapoli has approved $6 million in contracts to the firm, co-founded and chaired by Gore. Generation now manages nearly a half-billion dollars of state pension-fund investments, records show.

In total, that�s more than $35 million in greenbacks to Gore�s firm.

Liu�s office proposes investment-management contracts to the board of trustees of the city�s five major pension funds. Generation is an investment manager for two of them: the New York City Employees Retirement System (NYCERS) and the Police Pension Fund.

But the Gore connection has been a closely held secret.

One NYCERS trustee said he didn�t even know Gore�s firm was a city investment manager.

�That�s been way under the radar. I was unaware of it,� said NYCERS trustee Gregory Floyd, head of Teamsters Local 237.

Gore, who won a Nobel Peace Prize in 2007 for his campaign to tackle global warming, is a leading proponent of �sustainable capitalism.� He focuses on the long-term value of companies that address risks like climate change and slams the market�s obsession with short-term profits.
