Jim Roddy says people who drop litter in Derry city centre should be 'named and shamed'
Londonderry's city centre manager has called for people who are caught on CCTV dropping litter to be "named and shamed".
Derry City Council spent almost £2m on street cleaning last year.
It said it would review its enforcement of on-the-spot fines for littering. Only 20 were issued in 2008, and 17 in 2007.
Jim Roddy from the City Centre Initiative said the £2m was coming out of the pockets of ordinary people.
"We're all paying for this, yet there are people every day walking around the city and dropping litter with gay abandon.
"If we've got CCTV of pictures of that we should be showing them to people and saying these are the people that are making you spend more money, and then maybe people will sit up and take notice," he said.
Tidy Northern Ireland revealed the 26 local councils in Northern Ireland are spending almost £30m every year trying to clean up the mess left behind by careless litterers.
The charity, which is hosting a summit in Belfast, said councils must do more to try to stop the problem at source.
It says this can be done by education, enforcement and public engagement.
"When people throw litter on the ground, they might as well be throwing away five pound notes," Tidy NI chief executive Dr Ian Humphreys said.
"It is staggering to think about the huge sums of money that councils have to spend just because people can't be bothered to dispose of their rubbish in the correct manner.
"The actions of these people are hitting all of us in the pocket, hiking up our rates at a time when people need every penny."
Belfast spends the most per head on tidying litter, with the top five in the expenditure table completed by Moyle, Craigavon, Cookstown and Derry councils.
