Summary
• Innovations, new production techniques and design optimisation
will significantly reduce emissions – first projects show ±50%
reduction potential
• 87-98% of CO2 in construction is emitted through supply chain
• ‘MKI’ helps to analyse full life cycle impact of construction projects
– CO2

Recommendations
• Invest in knowledge, resources and tools to quantify and optimise
project impact
• Early involvement of client, contractor and supply chain partners
make construction project more sustainable
• Include criteria to evaluate quality of tenders based on CO2/MKI!
– Benefit for clients
– Benefits for BAM
• Reward sustainable performance in contract awarding
