Professor Brian Ó Gallachóir:

Related to that, and which comes out in volume 2, in general we spend a great deal of time looking ahead and do not spend enough time looking back and doing ex-post analysis of policies and measures to try to help explain how we got here in certain areas. This is one example where it would be useful to explore what policies and measures got us to this point and what policies and measures could have been introduced. As Professor Caulfield mentioned, we have policies and measures which are being considered now on weight but if we had introduced those sooner, what would the emissions impact have been? Ex-post analysis in general is an important feature which is too often neglected in how we do things. I thank the Cathaoirleach.
