Carbon Accounting

Understanding Carbon Accounting in Logistics

What is Carbon Accounting?

As organizations accelerate their sustainability and ESG initiatives, one fundamental question arises:

"How much carbon is our supply chain actually generating?"

To answer this question, businesses rely on Carbon Accounting.

Carbon Accounting is the process of measuring, calculating, tracking, reporting, and managing greenhouse gas (GHG) emissions generated by an organization's activities.

In logistics and supply chain management, Carbon Accounting helps businesses understand the environmental impact of transportation, warehousing, packaging, and supply chain operations, enabling them to make informed decisions to reduce emissions and achieve sustainability goals.

Simply put:

"You cannot reduce what you cannot measure. Carbon Accounting provides the foundation for decarbonization."

Why Carbon Accounting Matters

Governments, investors, customers, and regulators increasingly expect organizations to disclose their environmental impact.

Carbon Accounting helps organizations:

✅ Measure carbon emissions

✅ Identify emission hotspots

✅ Support ESG reporting

✅ Meet regulatory requirements

✅ Track sustainability performance

✅ Develop decarbonization strategies

✅ Achieve Net-Zero commitments

The Role of Carbon Accounting in Logistics

Logistics operations generate emissions through:

Transportation

Warehousing

Packaging

Energy consumption

Cross-border operations

Reverse logistics

Carbon Accounting provides visibility into where emissions are generated and where improvement opportunities exist.

Understanding Greenhouse Gas Emissions

Carbon Accounting typically measures emissions in:

CO₂e (Carbon Dioxide Equivalent)

Different greenhouse gases have different impacts on global warming.

To simplify reporting, emissions are converted into a common unit called:

CO₂e = Carbon Dioxide Equivalent

This includes:

• Carbon Dioxide (CO₂)
• Methane (CH₄)
• Nitrous Oxide (N₂O)
• Other greenhouse gases

Why CO₂e?

It provides a standardized way to compare environmental impacts.

The Three Emission Scopes

A key concept in Carbon Accounting is the classification of emissions into three categories.

Scope 1: Direct Emissions

Emissions generated directly by company-owned assets.

Examples

Company-owned trucks

Company-operated facilities

Fuel combustion

Logistics Examples

• Fleet fuel consumption
• Warehouse heating systems
• Material handling equipment

Controlled by the Organization

✅ Yes

Scope 2: Indirect Energy Emissions

Emissions associated with purchased energy.

Examples

Electricity

Heating

Cooling

Logistics Examples

• Warehouse electricity consumption
• Distribution center operations
• Office facilities

Controlled by the Organization

✅ Partially

Scope 3: Value Chain Emissions

Emissions generated by activities outside direct organizational control.

For logistics organizations, Scope 3 is often the largest category.

Examples

Third-party transportation

Supplier operations

Product packaging

External freight providers

Product returns

Logistics Impact

Scope 3 often represents more than 70% of total supply chain emissions.

Controlled by the Organization

❌ Indirectly

Why Scope 3 Matters Most in Logistics

Many logistics providers outsource activities to:

• Carriers
• Airlines
• Ocean carriers
• Warehousing providers
• Suppliers

As a result, much of the supply chain's environmental footprint lies outside direct business operations.

Examples

• Contracted trucking companies
• Ocean freight providers
• Third-party logistics providers (3PLs)
• Suppliers and manufacturers

Challenge

Obtaining reliable emissions data across the supply chain.
