Protecting the future
Over 10,000 trees planted…
and counting
We are proud to have achieved carbon neutral positive status with Carbon Footprint Ltd. They have assessed our carbon emissions within the business, and we have offset our carbon footprint with a School treeplanting scheme in England and an Amazon rainforest preventing deforestation scheme.
In addition to this we have launched our ‘Plant Hire – Plant Tree’ initiative which for every week’s boat hire we plant a tree. This has seen us plant over 2850 native trees in the last year alone and over 10,000 since the scheme started.

Following the storm seasons of 2023 & 2024, the EA set out to review its impact on the UK’s waterways. The River Derwent in Derby was flagged after a sonar scan of its navigation identified a scour hole – a direct result of heavy rainfall pushing sediment downstream.
