Liberia's largest palm oil company, Golden Veroleum, has quit a global eco-certification body in response to accusations from a global watchdog that it failed to get consent from communities before expanding onto their lands, the firm said.

The Roundtable on Sustainable Palm Oil (RSPO) a voluntary global certification body for the industry, ruled that the Singapore-controlled company violated its commitments.

The RSPO is aimed at getting palm oil firms to adopt environmentally and socially responsible policies in an industry with a long history of land grabs and rainforest destruction.
