Major transport and urban projects increase material demand, making supply stability, price movements and greener production important issues.

Industry developments
Green construction extends from individual energy measures to lifecycle management of materials, construction, operation and refurbishment. Assessment requires clear project boundaries and data.
Engineering practice
Supply, cost, performance and material availability influence low-carbon solutions. Project teams must balance safety, quality, programme and environmental requirements.
Further observations
Follow new criteria, measured data, material supply and operating performance to assess whether green measures can be applied more widely.
