New paper published: Reaching net-zero carbon emissions in construction supply chains – Road 44

Recent estimates suggest that the construction sector accounts for approximately one quarter of global CO2 emissions. This paper assesses the potential for reducing the climate impact of road construction. The results indicate that it is technically possible to cut in half road construction CO2 emissions with today's best available technologies and practices, to abate more than three quarters of the emissions by 2030 and achieve close to net zero emissions by 2045.

Highlights

• Achieving current halving, and close to zero CO2 road construction by 2045 possible.

• Upscaling of sustainable biofuel and recycling are priorities in the short-term.

• Zero CO2 requires electrification of machinery/transport and basic industry (or CCS).

• To realise this: Develop, monitor and coordinate industry decarbonization pathways.

• Build on, support and strengthen cross-sectorial collaborations.
