Conor Horgan from IBAL said no area suvered were found to be "heavily littered".
Speaking on RTÉ's Morning Ireland, he said: "We've been monitoring our coastline for the last eight years. If I go back just a few years, there was only a handful of areas deemed 'clean'. This morning's report shows that the majority of our beaches and harbours are clean.
"The other side of the coin at the bottom end of our table, we had no areas deemed litter black spots."
Mr Horgan said, despite "lots of traffic to our beaches" over the summer months, "this is very good news".
He said Portmarnock Beach had a "notable improvement". The Dublin beach was deemed "littered" in the last survey and is now "clean".
Mr Hogan also said Blackrock Castle and Castletownbere in Cork had similar improvements.
He said the majority of litter found at beaches and harbours is from sweet wrappers, plastic bottles and cans.
The survey found vapes were less prevalent than in previous years.
However, it found there was no decrease in litter from coffee cups, which were found in 42% of the areas surveyed.
