LONDON (Reuters) - A U.N.-backed banking climate coalition on Wednesday released updated guidance for members requiring them to disclose more about how they plan to cut carbon emissions, including for the first time those from their capital markets activities.

The Net-Zero Banking Alliance whose 143 members oversee $74 trillion in capital said the guidelines will also see more data disclosed on client transition planning and advocacy.
