THEY are part of centuries-old tradition, but now sky lanterns could be banned on all county council owned property.

Usually made of tissue paper, firelighters or candles, and a wire frame, the lanterns can measure up to 30cm, and have become increasingly popular at parties or memorials.

They are traditionally used across China, Thailand, Taiwan, Portugal and Brazil for celebrations.

However animal welfare groups say they are dangerous, and in 2011 Hampshire County Council unanimously passed a motion calling on the Government to ban their use.

Today council leader Roy Perry will consider banning sky lanterns on all county-council owned property.

He said: “We've been concerned about the safety of sky lanterns and the potential damage they can cause for some time and debated the matter three years ago.

“As well as their impact on the environment, livestock and animals including littering on land and at sea, they are a potential hazard to air traffic, coastal shipping and consumer safety.

“Given these concerns, and in the absence of a Government ban, at my decision day as Executive Member for Policy and Resources, I will be considering a ban on their use on all county council-owned property. I will also be considering writing to schools urging them to consider imposing a similar ban relating to events and activities in their grounds and premises.”
