TOKYO -- Japanese companies are forming an alliance this month to disclose the risks posed by climate change to their businesses, taking a step toward greater transparency in an area where corporate Japan has lagged its Western peers. The move seeks to attract long-term investment as environmental, social and governance criteria rapidly become a factor in how institutional investors in the U.S. and Europe allocate their capital. The Japanese corporate group will support proposals by the Task Force on Climate-related Financial Disclosures, created by the Financial Stability Board, an international body of financial regulators headquartered in Basel, Switzerland.
