Biography
In 2003, he had a near-fatal accident while filming a documentary in Chernobyl. In April 2014, he vowed to walk out of an interview on the Newstalk Breakfast Show unless he was given more time to speak on the topic of climate change. During the interview he claimed that climate change is not sufficiently covered by the Irish media. In 2018, he and George Lee (also of RTÉ) were promoting the Nissan Leaf. In 2023 he retired from RTÉ as Eco Eye was axed. That same year, he was awarded the Freedom of the City of Dublin by Green Party Lord Mayor of Dublin Caroline Conroy.
