Special Project Session 2 - Carbon neutrality of the road sector

Wednesday, October 4 14:30 - 18:00
Chair: Patrick MALLÉJACQ, Secretary General of PIARC
Room: Conference Hall, 4th floor

Road transport is vital for society to function and, for the foreseeable future, is expected to remain the dominant mode of transport for people and goods. However, the construction, operation, maintenance and use of the highway infrastructure are responsible for large quantities of carbon emissions. Knowledge of the non-reversible, damaging consequences of climate change has resulted in global acceptance of the need to reduce carbon emissions in all sectors of human activity, including the highways sector. However, as efficient transport is vital to national economic growth, actions to reduce carbon emissions must not negatively impact the development and maintenance of high-quality road infrastructure, particularly for LMICs.

This session aimed to identify actions being undertaken as well as potential new options to progress towards carbon neutrality.
