In 2011 Selfridges launched Project Ocean – a landmark campaign using the power of retail to help protect our precious oceans.  In the nine years since it started, Selfridges has done everything from being the first retailer to ban single-use plastic water and carbonated drinks bottles, to setting up a 50-hectare marine reserve in the Philippines.  In this final episode of SELF-Sustainable, we look at the past, present and future of Project Ocean – including an exciting new announcement – as well as what we can all do to make some waves ourselves.
