Tools for Measuring Tools for Measuring SustainabilitySustainabilityEuropean TechnologyEuropean Technology

The tool focuses on giving an estimate of the CO2 saved in selecting different construction techniques and supply alternatives (use of primary or recycled and secondary aggregates).

The tool uses Microsoft Excel and is designed to assess the CO2 output resulting from four types of construction involving aggregates:

– • bitumen bound – • cement bound– • water bound– • unbound

A few Comments from England:A few Comments from England:– Because of the potential environmental impacts of major

construction projects, alternatives to new road construction will be thoroughly investigated first. (Recycling)

– New roads are expensive. They impose substantial environmental costs. Can problems can be solved by making better use of the existing network before adding additional infrastructure? (Environmental Issues)

– Road-building must be accompanied by measures to lock in the benefits, i.e. prevent new traffic from filling up the new road space. (Restricted Traffic Use)
