World's biggest wealth fund excludes 52 coal-related groups

Norway's sovereign wealth fund divests from energy companies that derive more than 30% of revenues from coal, on ethical grounds

Norway's sovereign wealth fund, the world's biggest, has excluded 52 coal-related companies in line with new ethical guidelines barring it from investing in such groups, Norway's central bank said on Thursday.

The move was seen as a sign of the growing influence investors wield in the fight against climate change.
