Ameliorating global warming has been touted as one of the most pressing issues of our time. We investigate whether there are mutual fund families that purposefully decrease their portfolios’ exposure to greenhouse gas emissions, and find families that sign the Principles for Responsible Investment (PRI) have significantly lower portfolio emissions after signing the initiative than do non-signatory families. There are two mechanisms via which this reduction occurs: access to the resources offered by the PRI (networks, information, education, etc.), and families with pro-environmental stakeholders. Families that reduce their emissions experience significantly increased fund flow.

缓和的全球变暖被吹捧为当今时代最紧迫的问题之一。我们调查了是否有共同基金的家庭有意减少其投资组合的温室气体排放风险，并发现签署了《负责任投资原则》（PRI）的家庭在签署该倡议后的投资组合排放显着低于非签署者的家庭。减少排放的机制有两种：访问PRI提供的资源（网络，信息，教育等），以及拥有有利于环境的利益相关者的家庭。减少排放的家庭经历了显着增加的资金流动。
