Impact investing funds Arjuna Capital and Baldwin Brothers are set to put forth proposals on ways Facebook  (FB) - Get Report can be proactive in combating fake news at the company's annual shareholder conference on Thursday, CNBC reported. 

Facebook has taken steps in recent months to combat the problem, after widespread dissemination of fake news in the run up to last November's election showed just how pervasive the problem is. 

"The big risk to Facebook is a loss in user trust and people getting what has been coined 'Facebook fatigue' and turning away from the platform," said Natasha Lamb,  Arjuna's director of equity research and shareholder engagement.
