That is an argument but there is other evidence to show that it does not dramatically decrease emissions. If we look at the dramatic increase in emissions overall over the past few decades, this may be borne out. Carbon tax imposed on ordinary people to change their behaviour is a bad model, particularly in the model in Ireland where we have poor public transport, do not have access to cheap retrofitting and electric cars are expensive. Could Professor FitzGerald comment on the other part of my question?
