I know it is difficult to make political assessments. The IPCC has good wording where it considers predictions to be "likely", "less likely", "more likely", "very likely" and so on. For a country like Ireland, where there is a target of an 80% reduction in emissions by 2050, everything the witnesses are saying suggests that it must be a 100% decarbonisation. What is the likelihood of us facing that reality in a regulatory political assessment before 2030? If we set out on a less ambitious path for 2030 and, halfway there, the international rules and the political environment in Europe and elsewhere change, what is the percentage of probability that would happen? Assuming at some stage we will have a higher target within the international mechanisms to which we are a party, what is the advice for us?
