      Comparing supplier Product Carbon Footprints (PCFs)

      This guide shows how to review and compare PCFs in Emitwise.

      Introduction

      Sometimes you need to go beyond the high-level company data and dive into specific product carbon footprints (PCFs) to see which products contribute the most to your Scope 3 emissions. This guide shows how to review and compare PCFs in Emitwise.

      Step-by-Step Guide

      1. Go to Products Overview

        • Go to Analyze / Products Overview to see a list of products and their associated carbon footprints.

      2. Review the Product List

        • You’ll see each product’s PCF Intensity (kg CO₂e per unit), which indicates its carbon impact.
        • Other relevant information may include Product Category, Supplier, and Data Quality indicators.

      3. Apply Filters for Effective Comparison

        • Filter by Supplier, Product Category, or other custom fields.
        • Example: Compare only products within a specific category or from a particular supplier to see who’s offering the lowest carbon footprint options.

      4. Ask the Right Questions

        • Which product has the highest PCF?
        • Are there more carbon-efficient alternatives I can source?
        • How do PCFs differ between suppliers offering similar products?

      5. Interpret Your Findings and Engage Suppliers

        • If Supplier A’s product has a significantly lower PCF than Supplier B’s, it might inform your purchasing choices.
        • Discuss with suppliers having higher PCFs about possible reduction strategies or process improvements.

      Common Issues/Tips

      • Tip: For service-based suppliers, PCFs might be less relevant. In that case, focus on their Company Emission Factor from the corporate view.
      • Issue: Some suppliers may not have calculated PCFs yet. Encourage them to use Emitwise’s free calculation tools to get started.

      Conclusion

      By comparing PCFs, you pinpoint where to make strategic changes in your procurement practices. This data supports dialogues with suppliers to reduce product-level emissions and achieve broader climate goals.
