LONDON (Reuters) - Too few companies specify their prospective financial hit from climate change under a voluntary global disclosure code that needs wider backing from asset managers and others to be fully effective, a global regulatory body said on Thursday.Climate change can reduce the value of assets or subject companies to costs from flooding and other weather-related events, and a body dubbed the Task Force on Climate-related Financial Disclosures (TCFD) in 2017 published a voluntary set of disclosures to help inform investors. The TCFD, set up by the Financial Stability Board (FSB) which coordinates financial rules for G20 countries, said more than 1,500 organisations worldwide had expressed support for TCFD-aligned disclosures to help cut carbon emissions, up 85% since last year’s update. But the level of disclosure remains inadequate, it said. “Companies’ disclosure of the potential financial impact of climate change on their businesses and strategies remains low,” the TCFD said.
