Businesses leaders have hit back at a survey which found parts of the capital were a litter blackspot.
Dublin City Business Improvement District (BID) fears tourism, revenue and jobs could be jeopardised over what it claimed was misleading and untrue information on the cleanliness of the city.
It maintained the Irish Business Against Litter (IBAL) survey was amateur and included residential areas, presenting them as Dublin City Centre.
Richard Guiney, chief executive of Dublin City BID, said a tourist considering visiting the capital could be misled into believing it is dirty.
"The majority of Dublin's main tourist areas are recorded as clean," he said.
"While there are areas outside the BID area which are regarded as unclean, we note again that these are mainly in private or residential areas for example, in basements which cleaning organisations cannot access.
"It's also important to point out that these surveys are a snapshot of a point in time and are not representative of the true situation on the streets."
Trim was announced as the cleanest town in Ireland at an IBAL ceremony, pipping Swords and Killarney in the 2011 survey of litter levels in 53 towns and cities.
IBAL said 38 towns were classed as Clean to European Norms, while nine were moderately littered and Portlaoise, Letterkenny, Dublin City and Tipperary town were listed as littered.
However Dublin's north inner city and Knocknaheeny in Cork were both listed as litter blackspots.
