Yes "The Green Party does not have a specific policy on banning of goods produced in settlements, but we support the right of individuals to boycott goods produced by particular corporations and countries based on their human rights record."

Our South East Green MEP Keith Taylor meets PSC http://www.keithtaylormep.org.uk/2013/11/06/keith-meets-with-uk-palestine-solidarity-campaign/
Keith Taylor, Green Party MEP for the South East of England, met with Hugh Lanning, the chair of the UK’s Palestine Solidarity Campaign, to discuss the new EU guidelines on Israeli settlement funding which will come into force in January. The guidelines, launched in July, will serve to prohibit grants, prizes or funding from the EU to the settlements of the Golan Heights, West Bank, or East Jerusalem, captured during the Arab-Israeli 1967 war.
The Palestine Solidarity Campaign have been campaigning to ensure full implementation of the guidelines, following concerns that the Commission is facing intense pressure from Israel to water down their proposals. For example, it is believed that the EU is being pressured towards a compromise, such that Israel would not have to declare its compliance with the guidelines, but rather, the EU would be responsible for identifying breaches of the guidelines.
Ultimately, the Israeli settlements in the Occupied Territories are in breach of international law, and as such, the guidelines represent concrete actions to ensure the that EU funding is in conformity with international law.
Keith was very pleased to meet with Mr Lanning, to share their hopes that positive steps can still be made, and that the guidelines will be implemented in full. .
Earlier in October, Keith co-signed a letter to Catherine Ashton, the High Representative for Foreign Affairs and Security Policy, urging her to implement the guidelines properly, rather than giving into Israeli pressure. Keith also took the opportunity to discuss the current petition drawn up by Brighton and Hove PSC in his constituency, who are campaigning against a shop in Brighton which sells settlement products.
