I refer to the recently published document "Ireland, Climate Change, CO2 Abatement Strategy", a copy of which is in the Oireachtas Library. In line with EC policy, the strategy is concerned primarily with CO2, the principal greenhouse gas. An inventory of methane emissions will also be prepared under the strategy. CFC emissions will, of course, be substantially reduced by reason of the operation of the UN Montreal Protocol on substances that deplete the ozone layer, to which Ireland is a party. In reviewing the national strategy, account will be taken of the contribution of various emissions to the greenhouse effect and the possibilities which exist for limiting such emissions.
