How a Circular Economy Helps Cut CO₂ Emissions

Published: October 28, 2025 | By Chloe Williment | Sustainability Magazine

Understanding the Circular Economy and Its Impact on Emissions

The circular economy is a transformative model essential for achieving global net zero targets. Unlike the traditional linear system of take–make–consume–dispose, it focuses on keeping materials in use as long as possible through five key principles:

• Reduce
• Reuse
• Repair
• Redesign
• Recycle

This shift minimizes waste, reduces pollution, and lowers greenhouse gas (GHG) emissions linked to manufacturing and raw material extraction.

Why Transitioning to Circularity Is Crucial

• Waste Reduction: Recycling and reusing products slow down natural resource depletion, limit biodiversity loss, and curtail landscape disruption.
• Design Efficiency: Over 80% of a product’s environmental footprint is determined at the design stage, underscoring the need for sustainable product innovation.
• Packaging Concerns: Europeans generate approximately 190 kg of packaging waste per person annually, highlighting the urgency to curb excessive packaging and promote recyclable, reusable alternatives.

Didier Trebucq, UN Resident Coordinator in Georgia, emphasizes the circular economy’s triple win for people, the environment, and economic growth by fostering green jobs and cleaner communities.

Addressing Raw Material Challenges

Rising global demand and finite raw material supplies pose supply risks for the EU:

• Each European’s raw material consumption reached 14.9 tonnes in 2022.
• EU raw material trade in 2023 hit €165 billion (US$192.3 billion), with a €29 billion (US$33.8 billion) deficit.

Circular economy strategies reduce import reliance, stabilize prices, and safeguard access to critical raw materials essential for climate technologies like batteries and electric motors.

Economic and Consumer Benefits

The circular economy is projected to:

• Support up to 700,000 new EU jobs by 2030.
• Boost competitiveness and stimulate innovation.
• Deliver consumers longer-lasting, higher-quality products that reduce costs over time.

Jonquil Hackenberg, CEO of the Ellen MacArthur Foundation, champions scaling circularity initiatives across sectors to unlock these benefits.

Corporate Leaders Embracing Circularity

Several major companies exemplify circular economy practices:

• Cisco: Integrates 25 Circular Design Principles, achieving a 75% minimum circularity score on new products. Innovations like eliminating oil-based paint reduced costs by US$9 million and cut VOCs and CO₂e emissions.
• IKEA/Ingka Group: Focuses on product repair, reuse, buy-back programs, and spare parts to extend furniture lifespans.
• Blenheim Palace & Mastercard: Their RFID-enabled reusable cup scheme halved beverage packaging costs and prevented 320,000 single-use cups entering landfills.
• Accenture & Amazon Web Services: Building circular data lakes for automated sustainability measurement.
• CATL & Ellen MacArthur Foundation: Advancing battery reuse and high-quality recycling solutions.
• eBay’s Circular Fashion Fund: Supports repair, resale, and textile recycling.

These initiatives demonstrate how circular business models can drive resource efficiency, reduce emissions, and foster sustainable growth.

Conclusion

The circular economy offers a practical pathway to reduce CO₂ emissions by redesigning consumption cycles, conserving resources, and stimulating innovation. With growing corporate momentum and UN support, circularity is proving to be a crucial part of a sustainable, net zero future.
