Alongside a collaboration of scientific institutions and ocean groups from around the world, we've launched a new experiment to monitor the movement of plastic bottles in the ocean. A GPS signal will be sent from the bottles several times a day to provide a live update on their location, this allows us to monitor their progress and track how far they have travelled in real time.

About us

#OneLess was established in 2016 to reduce London’s single-use plastic footprint and tackle ocean plastic pollution at source. London is an estuarine city, directly connected to the ocean via the River Thames, and our actions in this city profoundly impact the ocean. When we started in 2016, Londoners bought over a billion single-use plastic water bottles every year, with many of these making their way into the River Thames and potentially flowing out to the ocean.
