Scope 3 decarbonisation across regional supply chains
Work directly with suppliers, contract manufacturers, and smallholder farms to reduce value chain emissions with verifiable primary data.
Overcoming the Scope 3 data challenge in Asia Pacific
For most enterprises in food, retail, logistics, and manufacturing, Scope 3 accounts for 75% to 90% of total emissions. Yet relying on generic spend-based industry averages prevents you from claiming actual supplier decarbonisation progress.
The 4-stage supplier engagement journey
Practical interventions taking supply chain partners from initial spend categorization to primary supplier emissions data.
Classify procurement spend across all 15 GHG Protocol Scope 3 categories to pinpoint high-carbon supplier tiers and hotspot materials.
Equip key Tier-1 and Tier-2 suppliers with practical carbon accounting templates, data capture workshops, and localized capacity training in Bahasa and Vietnamese.
Implement on-site solar, regenerative farming, packaging redesign, or fleet logistics improvements with joint financing models and supplier incentives.
Compile primary emission reduction certificates and immutable data trails recognized by corporate greenhouse gas auditors under ISSB and CSRD.
Frequently asked questions about supply chain emissions
Key answers on supplier surveys, data quality hierarchies, and decarbonisation pilots.
We start with environmentally-extended input-output (EEIO) spend models to establish a preliminary baseline. Then we prioritize the top 20% of suppliers generating 80% of emissions, providing them with simplified data collection templates in their native languages to replace generic proxies with primary data.
Across Asia Pacific, Category 1 (Purchased Goods and Services) and Category 4 (Upstream Transportation and Distribution) typically account for over 75% of total corporate value chain footprint. Focusing interventions on core raw materials and transport routing yields the most cost-effective carbon reductions.
Double-counting within a single company's inventory is prevented by strict adherence to GHG Protocol Scope 3 category definitions. When collaborating with suppliers, we use allocation factors based on physical output or contract value, ensuring each reduction is attributed once without overlapping claims.
Yes. AION structures joint financing mechanisms and buyer-backed Power Purchase Agreements where buyers aggregate supplier demand to negotiate lower equipment and clean tariff rates across industrial estates in Vietnam, Indonesia, and Malaysia.
