Cigarette butts now make up more than half of all our litter.

Mr Bruton stated: “Thinking twice about how we handle waste is the first step to respecting our environment and the planet we inhabit.
“Littering could be halved if cigarette butts were properly disposed of.
We seem to have a blind spot for this behaviour – it is six times more prevalent than sweet papers.
“Overall the survey shows some promising results. We see an increase in unpolluted areas and a decrease in slightly and significantly polluted areas.
“These results are thanks to the vigorous efforts made by individuals, community groups and Local Authorities in keeping their local area clean.
“However we do also see a very slight increase in the amount of grossly polluted areas, with cigarette related litter remaining the largest offender.
“The amount of chewing gum litter has halved since 2016, thanks in no small part to the co-operation between my Department and industry through the Gum Litter Taskforce.”
