I propose to take Questions Nos. 5 and 18 together.
Increased car numbers of the order indicated, with significant reductions in air pollution from stationary sources, make road traffic a relatively greater contributor to air pollution in Ireland than in the past. The recent Environmental Protection Agency report on the state of the environment in Ireland identifies road traffic as potentially the most serious source of air pollution, especially in urban areas. The agency predicts that vehicle emissions will continue to increase over the next five years before corrective measures, such as the compulsory fitting of catalytic converters to new cars, begin to bring about significant reductions.
As stated in reply to Question No. 109 of 28 May 1996, national policy in relation to CO 2 abatement recognises the likelihood of continued increases in CO 2 emissions from transport in the medium term and that measures in this area will play a key role in containing overall emissions. Important measures in this context include: implementation of the Dublin Transportation Initiative; improvement of public transport infrastructure; extension of vehicle testing requirements; and support by Ireland for EU measures to reduce CO 2 emissions from vehicles.
Under the Operational Programme for Transport, 25 per cent of total investment will be directed at the improvement of public transport infrastructure. Particular emphasis is being placed on the improvement of public transport in the greater Dublin area as the largest urban centre and the area offering the greatest potential for alternatives to road-based transport. Compared with a "do minimum" approach, implementation of the DTI recommended strategy is projected to secure a 5 per cent reduction in CO 2 emissions by 2001 and an 11 per cent reduction by 2011.
The forthcoming national sustainable development strategy will address sustainable transport in the context of providing a framework of objectives and policies for achieving sustainability in Ireland.
