The Financial Conduct Authority (FCA) is proposing to extend its sustainability rules to a wider range of investment products, including those managed by portfolio managers. This move is aimed at combating greenwashing, where companies make misleading claims about the environmental or social impact of their products or services. The FCA has already implemented an anti-greenwashing rule for retail investors, which requires firms to ensure that their claims are fair, clear, and not misleading. The new proposals would extend these requirements to a wider range of products, including those managed by portfolio managers.
