Waste Watch and Keep Britain Tidy are to merge, following a year-long strategic alliance.
The decision was taken by the two trustee boards and will result in a single charity, although the two organisations will retain their brands and offices and trade under Keep Britain Tidy.
The organisation will be led by current Keep Britain Tidy chief executive Phil Barton, while Waste Watch executive director Stewart Crocker will support the transition as a consultant.
The organisations will also undertake a review, with a view to publishing a new business plan and strategy in April 2012.
Waste Watch executive director Stewart Crocker said: “This is a momentous occasion for Keep Britain Tidy and Waste Watch. Individually both charities have made significant contributions to the way we view waste and litter over the years. But we believe we can increase the impact of both organisations through this merger.
“Waste Watch has successfully championed the social benefits of a sustainable lifestyle, showing how we can improve the well-being of communities whilst reducing their environmental footprint. This merger allows us, through our combined skills, resources and experience, to link up local and global issues using an approach that will make an even greater difference to people’s lives and the health of the planet.”
