International Construction Projects Sustainable construction
– tools to achieve environmental objectives in the climate change crisis

Thursday, April 25
Location (Room)

The Paris Agreement is a landmark treaty by which countries around the world have agreed to work together to combat climate change. The construction industry as a whole accounts for 36% of worldwide energy usage and 40% of CO2 emissions. Green construction therefore is particularly important for countries wishing to meet their carbon reduction targets. Stakeholders in the industry are taking steps to achieve this through setting new standards, engaging with new technology, repurposing existing structures through innovative thinking and designs, etc. At the same time, safeguards must be had against greenwashing. In this session, focus is placed in particular on:

  • Eco-clauses in contracts - what requirements could be included;
  • Certifications and standards in contact and obligation of the parties to obtain specific environmental clarifications;
  • Risk management in the context of sustainable construction - what specific risks can arise and how to allocate them
    • - incentive and sanctions – what motivates the contractor to meet environmental standards;
    • - materials and waste management;
    • - sustainable practices in the supply chain – controlled selection of subcontractors;
