"Where companies have not responded to our engagement or where we do not see sufficient progress and attention to climate risk over time, BlackRock Investment Stewardship continues to vote against directors and, where relevant, for shareholder proposals," spokesman Farrell Denby said by email. Vanguard spokeswoman Carolyn Wegemann confirmed the firm received a letter from Boston Trust Walden. "We responded in kind and expressed our willingness to meet and discuss this matter," she said. T. Rowe Price spokesman Brian Lewbart said the firm is evaluating the proposal. J.P. Morgan didn't immediately respond to requests for comment.
