On 5 June, churches and faith-based organizations from Colombia, the United Kingdom, and Ireland, together with investment and ecumenical partners, submitted a complaint under the OECD Guidelines for Multinational Enterprises on Responsible Business Conduct. The complaint concerns HSBC Holdings plc and its financial relationship with Glencore, the company operating the Cerrejón coal mine in La Guajira, Colombia. This is the third in a feature story series that illustrates the impacts of the Cerrejón mining operation on the environment, water access, and pollution.
