Cornwall Council has supported a proposal to ban sky lanterns from being released. Members backed a motion put forward by Mevagissey councillor James Mustoe against the small wire and paper balloons.
Countryside campaigners say the items present a fire risk and are a danger to wildlife and livestock, as well as being mistaken for distress flares.
Sky lanterns are small hot air balloons made of paper and plastic, with an opening at the bottom where a fire is suspended. They carry a risk of causing a fire miles from where they have been launched and can be a particular menace to crops and thatched properties.
Animals can also get entangled in them or eat them, which can cause serious problems or even death. The motion to ban their release from council-owned land received widespread cross-party support as well as being backed by conservation groups, charities and many members of the public.
Earlier this year, Fife council issued a warning after a sky lantern sparked a fire in Kirkcaldy, Fife.
