Towns and cities across the UK are sticking together to try get more done to clean chewing gum off the streets.
Councils in 20 places want companies that make chewing gum to contribute towards cleaning up the mess that it leaves on the streets.
The group says that every single piece of gum costs 10p to clean up, but only costs 3p to make.
They add that if gum companies handed over 1p from every pack sold it would add £9m to the clean-up fund.
A spokesman for Westminster Council in London said they spend £100,000 every year on cleaning up discarded chewing gum.
Alan Bradley added: "It is time the manufacturer and the people who throw this mess on to the ground take responsibility for their actions - it is time to make the polluters pay."
On Monday the Government-backed Chewing Gum Action Group is holding a conference on the issue too.
