This database contains the full outputs from the analysis, which is also updated every other year in line with the publication. It covers the travel demand, vehicle activities, energy consumption, as well as related CO2 emissions of all modes (existing and new emerging modes) for both freight...

This database includes annual information on CO₂ emissions related to commercial passenger and freight flights, on both a territory and a residence basis, for 186 countries. These CO₂ emissions are estimated by the OECD, based on a consistent methodology across countries.

What are the measures and strategies already taken by OECD countries to reduce or stabilise greenhouse gases from road transport? What frameworks exist to evaluate the impact and efficiency of these measures and strategies? And how effective are they? With the continued growth forecast in car...

Transport accounts for nearly a quarter of carbon dioxide emissions from fuel combustion. The price attached to these emissions is critical to climate policies and emissions mitigation efforts in the sector. As the impact of emissions on climate does not depend on where CO2 is released, the...

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...

Non-exhaust emissions of particulate matter constitute a little-known but rising share of emissions from road traffic and have significant negative impacts on public health. This report synthesizes the current state of knowledge about the nature, causes, and consequences of non-exhaust...

This report reviews vehicle emissions standards in Europe, Japan and the United States, providing the reader with valuable comparisons. It also examines incentives for sulphur free fuels - which can contribute to reducing both conventional air emissions and carbon dioxide. It describes emissions...

Transport sector policies already contribute to moderating greenhouse gas emissions from road vehicles. They are increasingly designed to contribute to overall societal targets to mitigate climate change. While abatement costs in transport are relatively high, there are plausible arguments in...
