U.S. asset managers factor greenhouse gas emissions and other climate risks into their debt investment decisions as much as peers in Europe, according to a survey released on Tuesday, despite the Republican campaign against climate-focused investing in the United States. Nearly a third of North American fixed income managers surveyed have underweighted investments they consider to have high carbon emissions and 16% have excluded them from portfolios, slightly more than the equivalent percentages for European managers, the survey published by NatWest found.
