Unit
- Net-zero design operations: A structured approach to creating products and services that result in no net greenhouse gas emissions throughout their lifecycle. This includes reducing emissions at every stage and offsetting residual emissions through verified carbon removal projects.
- Scope boundaries: Net-zero design requires a clear definition of system boundaries. Designers must account for direct emissions from owned sources, indirect emissions from purchased energy, and value chain emissions from suppliers and end users.
- Science-based targets: Organizations align their net-zero goals with climate science, typically following the Science Based Targets initiative (SBTi). These targets set emission reduction pathways consistent with limiting global warming to 1.5 degrees Celsius.
- Design for decarbonization: Integrating carbon reduction into the design phase is more effective than retrofitting. Decisions made during design determine the majority of future emissions, making early-stage interventions critical.
- Life cycle thinking: Net-zero design applies life cycle assessment (LCA) methodology to quantify environmental impacts from raw material extraction, manufacturing, distribution, use, and disposal. This prevents shifting burdens between stages.
- Carbon offsetting vs. reduction: True net-zero emphasizes absolute emission reductions first, using offsets only for unavoidable residual emissions. Offsets must be permanent, additional, and verified to ensure environmental integrity.
- Stakeholder alignment: Achieving net-zero design requires collaboration across departments including product development, procurement, manufacturing, and marketing. Shared metrics and accountability drive consistent progress.
- Continuous improvement: Net-zero is not a one-time certification but an ongoing process. Regular monitoring, reporting, and iterative design cycles help organizations adapt to new technologies and evolving standards.
- Supply chain engagement: Net-zero design extends beyond internal operations to include supplier collaboration. Organizations must work with suppliers to set emission reduction targets, share best practices, and incentivize low-carbon materials. This value chain approach ensures that upstream emissions are addressed systematically, reducing scope 3 impacts effectively.
- Circular economy integration: Designing for circularity complements net-zero goals by extending product life and enabling material recovery. Strategies include modular design for repair, design for disassembly, and using recycled content. These approaches reduce the demand for virgin materials and lower embodied carbon over multiple life cycles.
- Digital tools and data quality: Accurate carbon accounting requires reliable data. Designers should use digital product passports, blockchain for traceability, and automated LCA tools to capture emissions data. High-quality data enables informed decisions and transparent reporting, which is critical for verification and stakeholder trust.
Design Principle
Principle: Holistic Emissions Accounting
Definition: This principle requires designers to consider all greenhouse gas emissions across a product full life cycle, not just direct operational emissions. It ensures that decisions to reduce one type of emission do not inadvertently increase another, avoiding problem shifting.
Application: When redesigning a product, use life cycle assessment software to model the carbon footprint of each material and process alternative. For example, substituting aluminum with recycled plastic may reduce manufacturing emissions but increase end-of-life toxicity. Weigh tradeoffs using a complete inventory of scope 1, 2, and 3 emissions.
