In the 30 years since single use coffee mugs were introduced, an estimated 2 trillion of them have ended up in landfill.
The Environmental Audit Committee - which Caroline Lucas sits on - is looking to tackle the issue by 2023 and Greens have been calling for tough action sooner.
Coffee chains are under pressure to do something themselves and many are introducing fees or discounts to encourage reusable travel mugs.
Yorkshire & the Humber Green Party is looking to buy branded Ecoffee Cup which we can sell.
Ecoffee Cups are made from bamboo fibre and have a re-sealable no-drip lid, making it perfect to take with you everywhere you go.
The 'profit' we make from these will be invested in our local campaigning to elect more Greens.
*Please note that the final design may be different but rest assured it will be Green Party branded
