Environmental impact spans the full life cycle of a product or service, from suppliers, assets, travel, raw material extraction, and production, through to consumer usage, disposal, and recycling. Measuring that impact across complex global value chains starts with visibility of what ‘environmental’ actually covers and where those impacts sit along the chain.
To do this, organisations must bring together qualitative and quantitative data from the various categories, including primary data from supplier tiers, using traceability standards and lifecycle analysis approaches. By standardising this information into consistent frameworks and technology-enabled solutions, companies can establish a baseline, identify the areas driving the greatest impact and track progress over time.
Supplier and stakeholder engagement is also essential, as much of a business’ environmental impact sits outside its direct control. By working with suppliers, third-party verifiers, and others across the value chain to improve data quality and assess factors such as carbon intensity, resource consumption, and software efficiency, organisations can build a clearer picture of their overall footprint.
It’s important to remember that the data may not be perfect from day one. However, organisations that commit to using and improving it will be better positioned to reduce environmental impact across the value chain.
