interested countries and organizations. We ask ECE to review progress in this regard at regular intervals. (h) To introduce and update comprehensive policies to remove the existing barriers for market penetration of energy efficient technology, renewable energy and clean life-cycle technology and to promote energy efficient processes in all sectors. The funding of research, development and demonstration for renewable and non-renewable energy sources should be brought into a reasonable balance. In some countries, this should result in increased funding for renewables. (i) To reduce the harmful effects of the transport sector on the environment by promoting fast, safe and convenient urban and regional transport services and reducing urban car traffic by means of a co-ordinated strategy reflecting national circumstances to: improve the efficiency of public transport services such as railways, underground trains, and buses; favour use of more e~ergy efficient motor vehicles with low emission levels through economic, regulatory or other instruments noting, inter alia, the encouraging progress in the development of the lean-burn engine and that small car prototypes have achieved 2-4 litres per hundred kilometres in test conditions; consider the introduction of maximum speed limits, bans on idling, traffic-free urban areas, and bicycle paths; encourage physical planning and traffic management as instruments for promoting an urban development with a sound and clean transport infrastructure and low transport demand; encourage development of environmentally preferable alternative fuel vehicles and technologies; utilize information campaigns or other measures to encourage a change in transport behaviour; pay increased attention to air transport efficiency; further develop a jcint strategy within the ECE framework for improving and integrating public and goods transportation with railways and waterways in mainland Europe including the harmonization of technical standards in rail transportation, particularly with a view to developing transportation betw~an East and West Europe. (j) All relevant international organizations are requested:
