Bioenergy, including biofuels, could become a substantial tool for mitigating greenhouse gas emissions, locally and globally, possibly providing a large fraction of global primary energy supply by 2020. Exactly how large that share will be is not possible to predict with any precision, being...

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 summarizes and organizes presentations and discussions of the Round Table on Macro-, meso and micro infrastructure planning and assessment tools, that took place at Boston University, on 25 and 26 October 2007. The goal of the meeting was to investigate how recent research on direct...

The transport sector’s demand for oil is less price sensitive than any other part of the economy. This is partly because demand for transport services is relatively insensitive to price and partly because substitutes for oil in road transport are currently far from cost-effective. Evidence...

This paper summarizes and organizes presentations in the Round Table's presentations and discussions, draws conclusions when possible, and points out where opinions differ. It is divided in three main sections. First, the presentations and discussions provided an overview of the advances,...

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...

Les transports terrestres jouent un rôle crucial dans presque toutes les activités sociales et économiques. La fourniture et l'entretien des infrastructures nécessitent des ressources considérables. C'est pourquoi il est essentiel de les aborder selon les modalités les plus efficaces et...

Biofuels received USD 15 billion in subsidies in OECD Member countries in 2007, but did they deliver benefits in terms of climate change or oil security? Present policies make no link between support for biofuels and their environmental performance, and biofuels do not all perform equally well....

En 2007, les biocarburants ont reçu 15 milliards USD de subventions dans les pays membres de l’OCDE. Ont-ils pour autant apporté des bénéfices en termes de protection du climat ou de sécurité énergétique ? Dans le cadre des politiques actuelles, le soutien aux biocarburants n’est pas...

Long-life surfaces could substantially cut the costs of road works, including the delays they cause, especially on congested routes with heavy traffic. These surfaces use new materials that cost more than conventional asphalt and require special handling. This report presents the results of...
