Challenges facing the development of new drive train technologies and use of alternative fuels are posed by high investment costs associated with research, production and infrastructure development. Switching from internal combustion engines to electronic motors would sharply reduce energy demand and lower CO2 emissions from vehicles. Most urgent for governments in the region is development of guidelines for coordinated CO2 related taxation; as well as establishing regional fuel efficiency standards.Text1 digital file (51 p. : ill.)application/pdfenAUTOMOBILE INDUSTRYVEHICLESEMISSION CONTROLCARBON DIOXIDE EMISSIONSENVIRONMENTAL LEGISLATIONMECHANICAL ENGINEERINGNEW TECHNOLOGYENERGY EFFICIENCYGREENHOUSE GASESSynthesis Report
