For more than 30 years, Marine Conservation Society volunteers have walked the same marked 100-metre stretches of beach, recording every piece of litter they find. Their painstaking work is now showing how some changes in everyday products are making a measurable difference.
At Lunderston Bay on the Firth of Clyde, volunteers counted 2,441 plastic cotton bud sticks in January 2018. Three years later, after Scotland became the first part of the UK to ban plastic-stemmed cotton buds, they found five.
Across Scotland’s monitored beaches, the average fell from 465 cotton bud sticks per 100 metres in 2018 to 18 in 2021. England introduced its ban in October 2020.
Bag charges show up in the data
The figures also track the impact of carrier bag charges, introduced at different times across the UK. On comparable beaches, England saw bags fall from around 12 per 100 metres to three. The Marine Conservation Society now finds half a bag per 100 metres on average — 88% fewer than before the charges.
There is still plenty of work to do. Volunteers recorded 603,963 items last year, averaging 141 for every 100 metres, against an OSPAR target of 20 for a healthy beach. Plastic made up 87% of the litter and appeared on 99.5% of surveyed beaches.
Why it matters for Britain
The surveys give policymakers reliable evidence about which measures are reducing litter, while highlighting where further action is needed. They also show the value of volunteers maintaining consistent records across beaches from Scotland to Wales and England.
