Enhancing the State of Transport Modeling in IAMs

An expert workshop carried out within the framework of the European Commission FP7 ADVANCE project.

Jointly organized by the Netherlands Environmental Assessment Agency (PBL) and International Institute for Applied Systems Analysis (IIASA) 

The great challenge for transport in the twenty-first century is ensuring that its development is sustainable: meeting the growing mobility demands of billions whilst minimizing the consequent environmental and social impacts. The world’s current stock of cars, trucks, buses, two-wheelers, trains, ships, and airplanes already accounts for approximately one-fifth of all primary energy consumed by mankind and comprises 25% of all energy-related carbon dioxide emissions. Future growth could put further strain on natural resources and the environment.

Within the scientific community, Integrated Assessment Models (IAM) have become increasingly important tools for informing policy and decision making. Modelers have expended considerable effort in recent years to improve their representation of end-use sectors, particularly of transport. However, much work remains to be done, as capturing demand-side heterogeneity and consumer choices is challenging from a modeling perspective. 

The specific aim of the ADVANCE workshop on "Enhancing the State of Transport Modeling in IAMs" is to bring together transport sector experts from both inside and outside the integrated assessment modeling community, in order for meeting participants to benefit from the current knowledge base and, ultimately, to improve the scientific community's ability to develop robust transport-energy projections and conduct reliable mitigation analyses. Planned workshop topics include data availability and statistics, determinants of transportation demand, consumer choice and behavioral considerations, and infrastructural bottlenecks and spatial constraints.

Participation in the workshop is by invitation only.
