THE CIRCULAR ECONOMYA POWERFUL FORCE FOR CLIMATE MITIGATION
WHY THIS STUDY – KEY MATERIALS ACCOUNT
FOR 21% OF GLOBAL CO2 EMISSIONS
• Steel, plastics, aluminium and cement account
for 21% of global emissions
• Steel and cement alone emit more than light-duty
vehicles
• Discussions to date focus on supply side – with
significant challenges
• New processes, CCS, international competition,
large investment, large energy needs
• Demand side not in focus – but can be the
missing piece of the puzzle

High-value recycling and less
new material
High-value recycling
• Increased collection rates
• Design for disassembly and
improved materials
separation
• Less contamination and
downgrading of materials

Less material input for each
car, building etc.
Improved production
• Less production waste
• Avoid over-specification
Reuse of components
Improved design
• High-strength materials
• New design principles
• Variation in size
Fewer products to achieve
the same benefit
Higher utilisation
• Sharing of products
• Product as service
Longer lifetime
• Design for durability and
disassembly
• Long lasting materials
• Improved maintenance
• Remanufacturing
