and integrates environmental, social, and economic factors into purchasing decisions. It uses the approach and to evaluate impacts throughout the supply chain, from raw materials to disposal.
, , and impact assessments are key components. Organizations engage suppliers through performance measurement, , and incentives to drive sustainability improvements and innovation in their supply chains.

Sustainable sourcing and procurement integrates environmental, social, and economic considerations into organizational purchasing decisions and processes
Triple bottom line approach (people, planet, profit) balances social, environmental, and economic factors in procurement decisions
Life cycle assessment (LCA) evaluates environmental impacts of products and services from raw material extraction to disposal
Considers energy use, emissions, water consumption, and waste generation at each stage
Helps identify hotspots for improvement in the supply chain
principles increasingly integrated into sustainable procurement practices
Design out waste and pollution
Keep products and materials in use (reuse, repair, remanufacture)
Regenerate natural systems
Supplier Standards and Risk Management
Supplier codes of conduct set expectations for labor practices, environmental management, and ethical business conduct
used in supplier selection and evaluation processes
May include certifications (Fair Trade, )
Environmental management systems ()
Transparency and traceability in supply chains verify sustainability claims
Tools include supplier questionnaires, third-party audits, and blockchain technology
Risk assessment and management strategies identify and mitigate sustainability-related risks
May involve , scenario planning, and diversification of supply sources
Environmental and Social Impacts of Supply Chains
Environmental Impact Assessments
assesses greenhouse gas emissions throughout the supply chain
Includes direct emissions from operations and indirect emissions from purchased energy and transportation
Helps identify opportunities for emission reduction (renewable energy, efficient logistics)
evaluates direct and indirect water consumption and pollution
Considers water use in production processes, agriculture, and product use
Identifies water stress hotspots and conservation opportunities
examines effects on ecosystems and species diversity
Particularly important for sourcing from sensitive or protected areas
May involve habitat conservation efforts or sustainable harvesting practices
assesses long-term sustainability of raw material sourcing
Considers scarcity of non-renewable resources
Explores potential for circular or regenerative practices (recycled materials, bio-based alternatives)
Social and Economic Impact Evaluations
consider labor conditions, community relations, and human rights
Evaluates factors such as fair wages, worker safety, and local community engagement
May involve stakeholder consultations and human rights due diligence
evaluate effects on employment and community well-being
Considers job creation, skills development, and support for local businesses
May involve local sourcing initiatives or community investment programs
Waste generation and management assessments examine product lifecycle
Identifies opportunities for waste reduction, recycling, and responsible disposal
Considers impacts on local waste management infrastructure and communities
Supplier Engagement in Sustainability
Performance Measurement and Improvement
assess and track performance on key metrics
May include environmental indicators (energy efficiency, waste reduction)
Social indicators (labor practices, health and safety)
