17TH World Congress on Road Winter Service, Resilience and Decarbonisation - Pre-proceedings of the Congress

Workshop 08 - Unlocking decarbonisation in road construction & maintenance

Thursday, March 12 11:30 - 13:00
Chair: Louis Bettini, Chair TC4.5, Australia
Room: Room 6

How can the road sector accelerate its transition to low-carbon practices? PIARC’s Technical Committee 4.5 is leading global efforts to identify and reduce carbon impacts across all phases of road projects. In this interactive workshop, the Committee will share its latest findings and practical solutions, drawn from case studies, literature reviews, and international surveys. Delegates will gain insights into real-world decarbonization impacts, supported by clear indicators and best practices, and be able to directly challange committee members.

*What to expect: 
 -A deep dive into logistical and technological challenges for decarbonsiation in construction and maintenance—and strategies to overcome them.
 -Practical examples of mitigation measures that deliver measurable carbon reductions.
 -An interactive discussion with experts shaping global standards for sustainable roads.

*Core topics covered:
 -Improving efficiency in road construction and maintenance processes.
 -Innovative technologies for decarbonization including low carbon materials and design.
 -Decarbonizing project logistics to reduce emissions across supply chains.
 -Lowering emissions from equipment used in construction and maintenance.
 -Carbon calculators – tools for accurate measurement and informed decision-making.

*Why attend?
 -This session is an opportunity to learn from global best practices, directly engage and question leading experts from TC4.5, and take away actionable strategies for reducing carbon emissions in your projects.
