This short outlook is designed to test the potential for key policy instruments for mitigating emissions from road transport, and particularly from light duty vehicles, the largest source of CO2 emissions from transport (see Figure 1 and Table 1). It also examines uncertainties in the baseline...

This report investigates how tax revenue from transport fuels could evolve over time as vehicles rely less on fossil fuels, with a focus on the case study of the Republic of Slovenia. Reducing the reliance on fossil fuels in the transport sector is a welcome development from the perspective of...

This study assesses the impact of international sulphur emission reduction regulations on global shipping. Ships emit a large amount of sulphur oxides that have significant health impacts. To mitigate these, international regulations cap the sulphur content of ship fuel. In certain parts of the...

This report examines how lowering vehicle mass can reduce CO2 emissions from road transport. The average mass of new passenger cars in the European Union has increased by around 40% over the past four decades. Lowering vehicle mass to levels observed in the mid-1970s could reduce vehicle...

Governments around the world are increasingly intervening in automobile markets to improve fuel economy and reduce emissions of CO2 from new vehicles. This report reviews the rationale for such intervention and examines measures for maximum effectiveness and minimum cost. The Round Table brought...

Transport sector policies already contribute to moderating greenhouse gas emissions from road vehicles and are increasingly designed to contribute to overall societal targets to mitigate climate change. The Round Table investigated the effectiveness and costs of various mitigation options. The...

This paper reviews opportunities and challenges for mitigating greenhouse gas emissions from Azerbaijan’s transport sector. It provides an overview of Azerbaijan’s transport system and reviews the country’s existing policies and future plans for reducing CO2 emissions from transport. The...

This report reviews the effectiveness of carbon pricing, how it might be applied to the shipping sector and with what effects. It also evaluates recent proposals by countries to introduce a price on shipping’s carbon emissions and examines related policy issues.
