A spokesperson for the RCN declined to say which companies were in its portfolio when contacted by POLITICO. The group said it was “committed to social responsibility” and stressed that it did not invest in weapons manufacturing or any “ethically unacceptable practices.”

‘True ethical investment’

The Nurses for Palestine and NGO Corporate Watch report draws on a United Nations investigation into what its human rights council calls Israel’s “Economy of Genocide” to identify companies that activists say link fund managers to Israel’s occupation of the Palestinian Territories.

The International Court of Justice is currently considering allegations of genocide against Israel, while an independent U.N. inquiry found Israel was committing genocide against the Palestinians. Israel has adamantly rejected those allegations and argued it upholds its obligations under international law.

The companies named in the UN report include U.S. tech firms that provide Israel with cloud and artificial intelligence technology. These are among the most widely held shares in the world and are mainstays in the portfolios offered by popular fund managers, which often track the performance of the stock market.

A Palantir spokesperson told POLITICO the company rejected its inclusion in the U.N. report and referred to previous statements clarifying its partnership with the Israeli military.

The report — which follows two open letters whose signatories include 100 RCN members — does not present evidence that the union directly holds shares in companies more directly involved in the arms trade. But it argues that “true ethical investment” should look beyond investors’ own portfolios and at their fund managers’ “wider practices.”
