Tourism Ireland has launched a Conference CO2 calculator app for the iPhone. The free app has been developed to help conference and events professional check the carbon emissions associated with international delegate travel. It also offers tips on hosting greener meetings. “One of the main reasons delegates choose to come to Ireland is its green credentials,” said Tourism Ireland’s Deputy Director Great Britain David Boyce. “The iPhone app, coupled with the opening of The Convention Centre Dublin further underlines the destination’s commitment to green and we hope this encourages more people to choose Ireland for their event.” Through the app, users will be able to specify departure locations, compare the emissions used and evaluate their event with travel to Dublin. Venue and hotel special offers will also be featured.
