#OneLess is a rapidly growing movement of pioneering and progressive individuals, communities, businesses, NGOs and policymakers, collaboratively striving to reduce the amount of single-use plastic water bottles entering the ocean from the city of London.
By taking a systems-change approach, together we are championing London's refill culture by enabling innovative ways to quench the capital's thirst and stop our reliance on single-use plastic water bottles. Londoners currently drink more bottled water than anywhere else in the UK. The average Londoner buys 3.37 plastic water bottles every week that's 175 a year.
The #OneLess initiative is fostering a culture where using a refillable water bottle is the new social norm and we are working to ensure that the systems and infrastructure are in place across the city to support this behaviour.
#OneLess is working to ensure Londoners value and feel connected to the ocean. London is a coastal city, linked to the ocean via the tidal River Thames. Sadly, the river takes a relentless flow of plastic from the city to the ocean, and plastic water bottles are one of the most common items accounting for 10% of all litter items found in the river (plastic and non-plastic).
But its not too late to reverse this damaging current. A refill revolution is underway in London! With clean drinking water available out of the tap, Londoners are switching to refillable bottles to quench the capitals thirst and make throwaway, single-use plastic bottled water a thing of the past. Every time we refill, fewer single-use plastic water bottles pollute our streets, river and ocean.
All across London, people are joining the refill revolution, either by personally pledging to use a refillable water bottle instead of hundreds of wasteful single-use bottles, or by working to create a refill culture in their workplaces and communities.
And its not just in London. #OneLess can be adopted by cities and communities across the world. Its inclusive, experimental and systems-change nature means that lessons can be learned and shared, and the movement can be locally adapted and scaled up internationally.
Underpinning the #OneLess initiative are various programmes of work, including a major, multifaceted litter research programme along the River Thames, to determine levels of plastic entering Londons waterways and being carried out to the ocean. In partnership with teachers and London schools, a #OneLess education programme is being developed, that will be available online for schools across the UK and beyond. And importantly the entire movement is being monitored and evaluated to measure its impact and continually improve its approach.
The #OneLess initiative is led by the Zoological Society of London, Forum for the Future, the International Programme on the State of the Ocean and the Thames Estuary Partnership, with support from the Calouste Gulbenkian Foundation UK and the Oak Foundation.
