The number of pension funds and asset managers that refuse to invest in nuclear armament-makers appears to be growing, although financing is still abundant, an annual survey by anti-nuclear campaigners said Wednesday.

The report, entitled "Don't bank on the bomb," found that 22 financial institutions comprehensively prevented any involvement in nuclear weapon-producing companies in 2017, up from 18 in 2016 and 13 in 2015.

The new names included Norway's Government Pension Fund, Australia's Future Super, U.S.-based fund manager Green Century and Denmark's MP Pension, which manages pensions for Danish academics.
