Technology priorities for transport in Asia: assessment of economy-wide CO₂ emissions reduction for Lebanon

Abstract

This paper analyses the technology choices of countries that prioritized transport as a sector in Asia under the Technology Needs Assessment project. The countries used a wide variety of criteria to prioritize technologies which were related to the benefits technologies would provide, costs of technologies and availability of technology charactersitics. Non-motorized transport, mass transit and technologies that improve vehicle energy efficiency emerged as the three most preferred technology choices for the countries. These technology choices can be appropriate candidates for nationally appropriate mitigations actions (NAMA) given their strong contribution for developmentand therefore a methodology based on input-output decomposition analysis isproposed for analysing economy wide CO₂ emissions reductions. The methodologyhas been applied for the transport sector of Lebanon where alternative fuels,improvement to cars (private and taxis) and buses for public transport were prioritized by stakeholders. The economy-wide CO₂ emission reduce by 2,269 thousand tons by 2020 if the prioritized technologies are implemented in Lebanon. Fuel mix effect and structural effect would reduce CO₂ emission by 2,611 thousand tons, while the final demand effect would increase the CO₂ emission by 342 thousand tons.
