Résumé
This thesis explores climate mitigation instruments that would decarbonise, stimulate greening and foster leapfrogging in the Ethiopian road transport sector in general and cars in particular yet without compromising the many promises of enhanced mobility. To do so, a socio-legal approach and a broader designing approach involving ‘principles’ and frameworks that are common in climate and transport regulations - integration, leapfrogging, and complementary mixes - are used. Transport has a significant potential for long-term carbon mitigation plans, and more importantly, in developing countries that are not in an infrastructure/carbon lock-in situation. For this, Ethiopia is taken as a case study jurisdiction. Review of existing strategies revealed that Ethiopian mitigation strategies are ineffective to decarbonise the sector, and instead, other government policies and decisions have fuelled motorisation and hence carbon emissions. Equally, the comparative analysis presented in the thesis revealed that there is no single instrument that fits all countries’ situations. Thus, after a robust analysis of the socio-economic, political and environmental contexts of Ethiopia, the thesis presents additional instruments that would stimulate both the incremental and transformative changes required to decarbonise road transport. In the car regulation system, it is argued that a comprehensive and tailored mix of transport strategies and instruments that address both the demand and supply side of car market are needed. Hence, the potentials of fuel efficiency and carbon emissions standards, taxes, fiscal incentives, car use restrictions and other complementary instruments are discussed. Apart from the conventional mitigation strategies, the thesis argues that decarbonisation requires fixing regulatory loopholes and creating an integrated system in the importation/production, operation and final disposal of cars. It is also argued that instruments that stimulate non-motorised and mass transport, electric vehicles and integration of the modes are needed to open up the opportunity for a transport leapfrogging.
