The Climate Change Advisory Council will change the State's politics, and the lives of millions as Ireland finally begins to tackle its over-production of environmentally damaging carbon dioxide and other harmful gases
Already, its influence has been compared to the National Public Health Emergency Team (Nphet), though it will last for far longer than the body led by chief medical official Tony Holohan.
This week it has published carbon budget proposals setting out greenhouse gas emissions cuts for the next 15 years. The Government is expected to adopt and implement them – or at least try to do so.
So who are the members of the council which drew up the plans?
