All FTSE 100 and 250 CEOs - along with leading corporate law firms, the Confederation of British Industry, the Institute of Directors and the Association of British Insurers - have been sent a copy of Amnesty’s new 50-page report - Think Twice: Can companies do business with the Israeli settlements in the Occupied Palestinian Territories while respecting human rights? - which says that while a “thriving settlement economy” might appear to provide an attractive location for international businesses, no company can involve itself in this economy without contributing to - or being linked to - human rights abuses...[N]umerous...business sectors - including [tourism] banking, law firms, construction companies, and food and manufacturing companies - are...heavily implicated in the perpetuation and expansion of the settlements.Yet, under the UN Guiding Principles on Business and Human Rights, all companies have a responsibility to respect international humanitarian and human rights law wherever they operate in the world. Israel’s settlements breach the Geneva Conventions and amount to war crimes, and Amnesty is warning that no company - however it may seek to justify its involvement - can do business in or with the settlements in a way that is consistent with international humanitarian and human rights law.
