To mark ten years of the Global Greening tourism initiative, Taoiseach Leo Varadkar T.D. joined Tourism Ireland on 11th March to launch a new book, called Ireland’s Greening of the World.

The book tells the story of Tourism Ireland’s Global Greening since it began in 2010 and how it has since captured the imagination of people everywhere.

The initiative, which see hundreds of landmarks around the world light up green to celebrate the island of Ireland and St. Patrick, first began in Sydney when the Sydney Opera House went green on 17th March 2010.

The greening of Sydney Opera House was on the 200th anniversary of an historic event celebrating Ireland, hosted by the then Governor of New South Wales, Lachlan Macquarie.

The campaign has gone from strength to strength every year since, with around 360 sites in at least 51 different countries set to take part in 2019.

Tourism Ireland’s Global Greening complements the Government’s Global Ireland strategy, which will see the initiative grow to 600 participating sites by 2025.

The book is available to buy in bookshops and online at

An Taoiseach Leo Varadkar T.D. said: “The Global Greening project, like our diaspora, stretches across the world, to every continent, going beyond our historical connections into where we can now be found.”

Niall Gibbons, CEO of Tourism Ireland, said: “It is hard to believe that Tourism Ireland’s Global Greening is 10 years old. To mark the occasion, we have produced a special commemorative book, ‘Ireland’s Greening of the World’. We’re delighted the Taoiseach has agreed to launch it today.

“More than 70m people around the world claim links to the island of Ireland and St. Patrick’s Day is a truly unique opportunity to reconnect them with their heritage. We will distribute Ireland’s Greening of the World through Tourism Ireland’s offices around the world and through the Irish embassy network.”
