Analyse supply chain emissions

Scope 3 emissions typically represent 70-90% of most companies' carbon footprints. But tracking them is hard. You're dealing with hundreds or thousands of suppliers, each providing different products with different emissions profiles.

Most companies either skip detailed Scope 3 tracking (too complex) or calculate it once a year using spend-based estimates that don't reveal which suppliers or products actually drive emissions.

Gardenia breaks down Scope 3 emissions by supplier, product, and category - so you can see where emissions actually come from and prioritise reduction efforts.

What you can do:

• See total Scope 3 emissions - Supply chain emissions, emissions intensity, and year-over-year trends alongside revenue
• Break down by category - Identify which spend categories drive emissions (purchased goods, transportation, services)
• Drill into products - See line-by-line emissions for every product or service, with emissions contribution, spend, and carbon intensity (kgCO2e/spend)
• Analyse by supplier - View emissions by counterparty, including inbound and outbound transportation
• Sort by carbon intensity - Rank products and suppliers by kgCO2e per unit of spend to find the most carbon-intensive items
• Track transportation - See emissions from both inbound (supplier to you) and outbound (you to customer) logistics, including routes and modes

Why it matters:

Knowing your total Scope 3 emissions doesn't tell you what to do about them. The number might be 150K tCO2e, but that doesn't reveal whether the problem is one high-emitting supplier, one product category, or distributed across your entire supply chain.

With supplier and product-level breakdowns, you can see that one spend category - purchased goods and services - represents 97% of your upstream emissions. Within that, electronic components and supplies might be the main driver.

Then you can drill deeper: which specific products have the highest carbon intensity? A product with 4.02 kgCO2e per pound spent is very different from one with 2.00 kgCO2e per pound spent - even if the total spend is similar.

This granularity matters for decisions. Do you engage with your top 10 suppliers on decarbonisation? Switch to lower-carbon alternatives for specific high-intensity products? Focus on optimising transportation routes?
