The fund had also previously owned large stakes in oil companies Noble Energy and pipeline company Kinder Morgan Inc, according to disclosures.
Nomura's $13.5 million Nomura Global Climate Change Fund, launched in 2007 and ranked 16th-largest in the field, was among the most heavily invested in oil and gas at about 5.8 percent of its portfolio. Among the stock's holdings was a small stake in TransCanada Corp.
TransCanada became a symbolic enemy of the U.S. green movement in recent years over worries its Keystone project would have led to an increase in oil sands production. The project was rejected by the Obama administration on Nov. 6 on environmental grounds after a prolonged review.
A spokesman for Nomura said the fund was small and available only to investors in Taiwan. He did not respond to requests for comment about the fund's holdings.
Nomura's fund also held stock in Australia’s top oil and gas producer, Woodside Petroleum Ltd, and Norway's Statoil.
Another Taiwan-based fund, the Jih Sun Anti-Global Warming Fund, held a small stake in Enbridge Inc, a Canadian company that has proposed an oil sands pipeline to Canada's West Coast, a potential Plan B to the failed Keystone XL project.
The best performers in the climate fund field so far this year were portfolios that avoided fossil fuels entirely. A global glut in oil and gas supplies has crushed prices since late 2014 and in turn the share prices of producers.
They include Schroder’s $196 million ISF Glo Climate Change Equity fund, which was up 13.7 percent, and the $11.1 million Jupiter JGF Global Ecology Growth fund, which was up 10.8 percent – eye-popping returns in a lackluster overall market.
A spokeswoman for Schroder did not comment.
Among the biggest holdings in the five largest climate-focused portfolios as measured by assets under management were U.S. design and manufacturing firm Danaher Corp, U.S. wind energy and aerospace materials maker Hexcel Corp, and wind and solar power company NextEra Energy Inc.
