JPMorgan Chase's and State Street's investment arms on Thursday both quit a global investor coalition pushing companies to rein in climate-damaging emissions, while BlackRock said it has transferred its membership to its international arm, limiting its involvement.

The decisions together remove nearly $14 trillion of total assets from efforts to coordinate Wall Street action on tackling climate change and came after the coalition, known as Climate Action 100+ (CA100+), asked signatories to take stronger action over laggards.

Financial firms have faced growing pressure from Republican politicians over their membership of such groups, amid accusations that committing to shared action could be a breach of antitrust law or fiduciary duty.
