Why Scope 3 Emissions Account for 90% of Logistics Carbon: Complete Measurement Guide

Hello, I'm from GLEC, a company specializing in carbon emission measurement for the logistics and transportation industry.

If you're struggling to measure your logistics carbon footprint, you're not alone. The shocking truth? 90% of logistics emissions hide in Scope 3 - the part you don't directly control. Here's your complete guide to finding and managing these invisible emissions.

The 90% Problem: Understanding Scope 1, 2, and 3

The GHG Protocol divides emissions into three scopes. For logistics companies, the distribution is eye-opening:

Scope 1 - Direct Emissions (5-15%):

Company-owned vehicle fuel combustion
Warehouse heating systems
Refrigerant leaks from cold storage
On-site generators

These are emissions you directly create and control. Surprisingly, they're the smallest portion.

Scope 2 - Indirect Energy Emissions (10-20%):

Purchased electricity for warehouses
Office heating and cooling
Electric vehicle charging
Purchased steam or heat

These come from energy you buy but don't produce. Still relatively manageable.

Scope 3 - Other Indirect Emissions (70-90%):

Third-party transportation (upstream)
Customer deliveries (downstream)
Purchased goods and services
Employee commuting and travel
Waste disposal

This is where things get complicated. One logistics company discovered they had 10 owned trucks but worked with 3,000 partner carriers. Guess where most emissions came from?

Why Scope 3 Dominates Logistics Emissions

The logistics industry's business model creates this imbalance. Most companies don't own their entire fleet. They orchestrate a complex network of partners, subcontractors, and third-party providers.

Consider this typical scenario:

Your company: 50 trucks
Partner carriers: 2,000+ vehicles
3PL providers: Unknown fleet sizes
Last-mile delivery partners: Thousands of vehicles

Every shipment involves multiple handoffs, each adding to your Scope 3 emissions. Yet these are the hardest to track and control.

The 3-Step Carbon Measurement Process

Step 1: Data Collection

Essential data types in order of accuracy:

Fuel Data (Most Accurate):

Actual fuel consumption by vehicle
Fuel types (diesel, gasoline, LNG)
Receipts and fuel card records

Distance Data (Good Alternative):

Origin-destination actual distances
GPS tracking data
Shipment records

Cargo Data:

Weight in tons
Volume in CBM
Load factors

Vehicle Information:

Vehicle types and tonnage
Age and emission standards
Empty running ratios

The challenge? A logistics manager told me, "Getting data from 3,000 partners feels impossible." Here's how successful companies solve this:

Digitalization: Integrate TMS and ERP for automatic data capture
Partner engagement: Data sharing agreements with key carriers
Standardization: Universal collection templates
Phased approach: Start with top 20% of routes

Step 2: Emission Calculations

The basic formula seems simple: Emissions = Activity Data × Emission Factor × GWP

But implementation varies by data quality:

Fuel-based (Highest Accuracy): CO2 emissions = Fuel consumption (L) × Fuel emission factor

Distance-based (Medium Accuracy): CO2 emissions = Distance (km) × Vehicle emission factor

Ton-kilometer based (Lower Accuracy): CO2 emissions = Cargo weight (tons) × Distance (km) × Modal emission factor

Don't forget empty running! GLEC Framework requires allocating empty vehicle emissions to cargo. One expert joked, "Empty trucks now cost carbon, not just money."

Step 3: ISO 14083 Compliance

The 2023 ISO 14083 standard sets the global benchmark:

Well-to-Wheel approach: Include fuel production through combustion
All transport modes: Road, rail, sea, air
Transparency: Clear methodology documentation
Verification: Third-party validation recommended

GLEC Framework provides practical implementation guidance, offering industry-specific emission factors and detailed application instructions.

Navigating ESG Reporting Requirements

The reporting landscape is complex but manageable:

CDP Requirements:

Logistics-specific questionnaires
Target setting and progress tracking
Supply chain engagement programs

TCFD Compliance:

Climate risk and opportunity analysis
Scenario planning (1.5°C and 2°C)
Financial impact quantification

SBTi Validation:

Science-based target setting
Logistics sector guidance
Target verification process

One ESG manager confessed, "I spend all year writing reports." The solution? Systematic preparation:

Boundary Setting:

Choose organizational boundary (operational control, financial control, or equity share)
Define operational boundary (Scope 1 and 2 mandatory, Scope 3 materiality assessment)

Baseline Establishment:

Select year with reliable data
Create recalculation policy
Document all assumptions

Data Quality Management:

Prioritize primary data
Document secondary data sources
Clearly state estimations

Verification Preparation:

Internal verification systems
Documentation management
Third-party auditor selection

Turning Measurement into Action

"You can't manage what you can't measure" - this adage is especially true for carbon emissions.

Accurate measurement is just the beginning. It enables:

Targeted reduction strategies
Investment prioritization
Performance tracking
Stakeholder communication

The Scope 3 challenge is also an opportunity. By engaging partners in measurement and reduction, you create a sustainable ecosystem that benefits everyone.

Your Next Steps

Start measuring today - perfection isn't required
Focus on your largest emission sources first
Engage key partners in data sharing
Invest in digital solutions for scalability
Use measurement to drive reduction strategies

Remember, 90% of your emissions are in Scope 3. But 100% of the solution is in your hands.

The journey to carbon neutrality begins with understanding where you stand. Once you see the invisible 90%, you can start managing it effectively.
