Cafes in council-run buildings in Bristol are set to introduce a charge for single-use cups.
The 5p levy is aimed at deterring people from using the disposable cups, which are considered harmful to the environment.
People are being encouraged to take their own re-useable cups.
It is thought to be the first action of its kind passed by a local authority in the country.
The levy motion was passed by LibDem councillor for Westbury-on-Trym and Henleaze, Clare Campion Smith on Tuesday 12 December.
In the UK, up to 2.5 billion paper coffee cups are thrown away every year.
Only one in 400 cups is recycled because of the challenge of separating their plastic coating and cardboard in order to recycle the card.
No date has so far been set for the charges to come in to effect.
