A deposit scheme will be introduced at the Aviva Stadium for drinks cups at today's Six Nations match.
A one euro charge will apply that's refundable for the reusable cup to stop the use of single-use plastics at the ground.
There will also be no sachets of food condiments - and instead dispensers to reduce the amount of waste.
Martin Murphy, Stadium Director, said they want to continue to reduce the Aviva Stadium's carbon footprint.
"We're trying to eliminate single-use plastic," he said.
"The two initiatives we have are; the elimination of sauce sachets, and that'll save around 300,000 sachets going to landfill, and also we want to eliminate single-use plastic beakers for drinks."
