IEA Experts’ Dialogue on Material Trends in Transport

Venue: Centre de Conférence du Ministère des Affaires Etrangères (CCM), Paris

Background

Meeting Scope

The International Energy Agency (IEA) is embarking on a project to analyse material efficiency strategies and material use trends in different sectors of the economy. The project aims to estimate trends in the demand for key materials in the context of 2°C ambitions, as well as the resulting system-level impacts on energy demand and related CO2 emissions. As policy and markets drive the uptake of more sustainable transport patterns and technologies to meet climate objectives, the linkages between material demand and GDP are likely to diverge from historic trends. Demand for materials in transport may change due to strategies such as lightweighting and developing longer-lasting vehicles, intensifying vehicle use through new models of vehicle use (such as fleet-owned provision of mobility services), enhancing component reusability and recyclability, expanding public transit systems, and improving pavement durability and sustainability. These strategies will affect both the quantity and composition of materials demand, which will in turn have implications for CO2 emissions from the industrial sectors that produce key materials like steel, cement and aluminium. To provide strategic insights to this project, the IEA hosted an experts’ dialogue on 8 March 2018 in Paris. 

Workshop presentations and discussions explored current and future trends of materials use in transportation equipment and infrastructure, the implications of emerging transport technologies for materials demand, possible strategies to improve material efficiency and reduce the impact of material use in transport, and analytical methods for assessing current and future materials demand in the sector.

Target Audience

The meeting brought together leading experts and key stakeholders in materials production, vehicles manufacturing and transport infrastructure materials design and production from industry and the research community.
