Rockefellers to switch investments to 'clean energy'

Heirs to the Rockefeller family, which made its vast fortune from oil, are to sell investments in fossil fuels and reinvest in clean energy, reports say.

The Rockefeller Brothers Fund is joining a coalition of philanthropists pledging to rid themselves of more than $50bn (£31bn) in fossil fuel assets.

The announcement was made on Monday, a day before the UN climate change summit.

Some 650 individuals and 180 institutions have joined the coalition.

Valerie Rockefeller Wayne, chair of the Rockefeller Brothers Fund, spoke to the BBC about the decision.
