Scope 3 emissions are indirect and often lie outside your operational control, making them harder to track, verify, and reduce. Organizations typically face challenges such as:

• Incomplete or poor-quality supplier data
• Lack of visibility across tiers 2 and 3 of the supply chain
• Low supplier engagement or buy-in
• Limited internal resources or technical capacity
• Confusion around emissions factors, assumptions, and tools

And yet, tackling Scope 3 is what regulators, investors, and customers increasingly expect especially under CSRD, SBTi, and other ESG frameworks that demand full value chain transparency.

For most businesses, Scope 3 is dominated by upstream activities primarily purchased goods and services, which fall directly under the responsibility of procurement, supply chain, and category managers.

That makes supply chain decarbonization the most strategic and the most immediate lever for meeting net zero targets. Key hotspots often include: Raw materials such as metals or plastics, suppliers using fossil-fuel intensive energy, long-distance logistics and shipping, packaging materials, and end-of-life treatment.

This isn’t just about carbon. It’s about building resilient, responsible, and future-fit supply chains that deliver value beyond compliance.

You don’t need perfect data to start. Instead you need a clear roadmap, smart prioritization, and supplier collaboration. Here’s how to move forward:

1. Screen and prioritize Scope 3 categories
   Focus on emissions hotspots based on spend, material intensity, and strategic importance.
2. Map your supplier landscape
   Identify critical suppliers and clusters with the biggest footprint or influence.
3. Engage suppliers early
   Launch awareness campaigns, capacity-building sessions, and supplier scorecards.
4. Request relevant emissions data
   Start with spend-based estimates, then move toward activity-based reporting or primary data.
5. Embed sustainability into procurement
   Use circularity, low-carbon materials, and lifecycle impact as decision-making criteria.
6. Co-create reduction plans
   Work with suppliers to identify reduction levers e.g. renewable energy use, packaging redesign, or transport optimization.
7. Track and iterate
   Build a dashboard or reporting mechanism to monitor Scope 3 progress over time and feed it into CSRD, SBTi, or ESG reports.

Scope 3 emissions are where your climate story becomes real. They are complex, distributed, and harder to control but also where your biggest emissions and opportunities lie. If you’re not decarbonizing your supply chain, your net zero target is only a partial promise.

Start with what matters. Start with Scope 3.
