Ms Anne Graham:

We have a number of regional models that can model carbon emissions reduction we will get for different interventions. There is nothing wrong with the model and a significant amount of work has gone into developing it. The modelling is taking place. The work is under way at present but it is a significant piece of work and takes time to deliver. We do not have the information available for the Chair at present but we can make it available to him when the work is complete.

It will inform the type of questions being asked. If one has €10 billion, where does one put it to achieve the greatest reduction in carbon emissions? I want to see as much public transport infrastructure developed as possible. It is our remit. Of course, I would say the €10 billion should go into public transport infrastructure but there has to be a consideration of where to get the best reduction in terms of carbon emissions for the investment. The modelling work we are doing will help to answer those questions.
