The CEO of Tourism Ireland has said he hopes that nearly 400 global icons will be lit up in green for St Patrick's Day this year.
Niall Gibbons said 288 landmarks have been confirmed including Victoria Falls in southern Africa and the new Nations Tower in Abu Dhabi.
"We're delighted to see places like Victoria Falls, the largest waterfall in the world, lighting up green for St Patrick's Day.
"Great reflection on our new relationship, or developing relationship, with Africa.
"The Nations Stadium in Abu Dhabi, the Fukuoka stadium in Japan where Ireland will play Japan in the rugby World Cup this year. And over across the water - the Eden Project in Cornwall, which I think is a great tribute and a great reflection for Ireland over there as well, despite the woes we hear about Brexit every day."
He said the initiative has allowed Tourism Ireland to shine a light on Ireland at an important time in the tourism calendar.
Mr Gibbons said the initiative costs very little, around €30,000 so far this year but he claims the return is in excess of €10m.
Mr Gibbons told RTÉ's Morning Ireland that there were a few iconic places that he would like to see go green, including Buckingham Place.
But he added Queen Elizabeth has politely declined.
Mr Gibbons said the initiative gets a great reception globally and means a lot to the Irish diaspora.
"It's hard to describe the power of it. When you see things like Niagara Falls, the Empire State Building, the Sydney Opera House, it means an awful lot to people. Very, very emotive. And certainly when I show these images in presentations around the world, it's a very strong emotional impact that really does bring people together."
