Since 2016, we’ve been working to better understand the scale of the plastic pollution problem in the River Thames – discover what we’ve found so far.
London is a coastal city, with a direct link to the ocean via the tidal River Thames. Through the river, Londoners are connected to the ocean every day. Sadly, both the River Thames and the global ocean are under threat from plastic pollution, and single-use plastic water bottles are a major culprit.
Since 2016, #OneLess has been changing the way Londoners drink water – from plastic water bottles to refilling. We are tackling ocean plastic pollution at source by reducing, and ultimately eliminating, plastic water bottles from London. #OneLess works with major London businesses, cultural attractions, events, places and policy makers to find and implement solutions to enable a refill culture.
