Mr. Brian Carroll:

A couple of comments could be made on that. The €50 billion is based on today's costs. It is the total investment required, not distinguishing between what the State, and the private sector, might contribute. That is the first important distinction to make. The second is that in the climate action plan there is a new model of retrofitting to be brought forward where we are seeking to aggregate groups of houses and, through aggregation, achieve economies of scale. The expectation would be that over time the costs of retrofitting houses will fall.
