NEW YORK (Reuters) -West Virginia has added Citi, HSBC and two other financial firms to a list of institutions that may be barred from some state business due to their energy finance policies, prompting three of them to assert their commitment to that industry. The move was the latest flare-up in a bubbling dispute between Republican officials and Wall Street firms over use of environmental, social and governance (ESG) factors in banking and business. West Virginia, a major energy-producing state, created the list in 2002, placing five firms on it at the time.
