Scope 3 & Supply Chain Carbon

Understanding Scope 3 Emissions

For many organizations, the largest share of greenhouse gas (GHG) emissions occurs outside their direct operations. These indirect emissions are known as Scope 3 emissions and arise throughout the value chain.

Scope 3 includes emissions generated by suppliers, transport providers, waste treatment companies, and other partners involved in the production and delivery of goods and services.

Understanding and managing Scope 3 emissions has become increasingly important for companies responding to supply chain requirements, sustainability reporting and climate disclosure expectations.

Green Analytics helps organizations identify, structure and calculate Scope 3 emissions using internationally recognized carbon accounting methodologies.

Scope 3 in the GHG Protocol

Scope 3 emissions are defined by the GHG Protocol as all indirect emissions that occur in the value chain of a reporting organization. These emissions are typically grouped into upstream and downstream categories.

Upstream emissions may include:

• purchased goods and services;
• capital goods;
• fuel- and energy-related activities;
• upstream transport and distribution;
• waste generated in operations;
• business travel;
• employee commuting,

Downstream emissions may include:

• transport and distribution of products;
• processing of sold products;
• use of sold products;
• end-of-life treatment of products;
• downstream leased assets;
• investments and other value chain activities.

Depending on the organization and sector, Scope 3 emissions can represent the majority of the total carbon footprint.

Identifying Relevant Scope 3 Categories

Not all Scope 3 categories are equally relevant for every organization.

Green Analytics supports companies in identifying material Scope 3 sources by evaluating:

• operational activities;
• supply chain structure;
• industry-specific emission sources;
• data availability and reliability.

This process ensures that Scope 3 calculations focus on the most significant emission sources within the value chain.

Data Collection from the Supply Chain

Collecting reliable Scope 3 data can be challenging because emissions originate from external partners and suppliers.

Green Analytics helps organizations structure supply chain carbon data through:

• supplier questionnaires and data requests;
• activity-based data collection;
• transport and logistics data analysis;
• procurement and purchasing data evaluation.

Where direct supplier data is not available, emissions can be estimated using recognized calculation approaches and emission factor databases.

Calculation Approaches

Scope 3 emissions can be calculated using several recognized approaches depending on data availability.

Typical methods include:

• supplier-specific data provided by suppliers;
• activity-based calculations using operational data;
• spend-based estimation methods when activity data is not available;
• hybrid approaches combining multiple data sources.

Green Analytics selects the most appropriate approach based on the quality of available data and the reporting objectives of the organization.

Supply Chain Carbon Transparency

Many organizations now require their suppliers to disclose carbon footprint data.

Supply chain carbon transparency is increasingly driven by:

• corporate sustainability reporting;
• climate commitments and net-zero strategies;
• customer carbon disclosure requirements;
• ESG and climate reporting frameworks.

Green Analytics helps companies prepare supply chain carbon data that can be shared with clients, partners and sustainability platforms.

Preparing Scope 3 Data for Reporting

Scope 3 emissions are commonly required for:

• corporate carbon footprint reporting;
• sustainability reports;
• supply chain carbon disclosure;
• climate strategy development;
• ESG and climate reporting frameworks.

Green Analytics structures Scope 3 calculations so that they are consistent, transparent and aligned with recognized carbon accounting standards.

Supporting Supply Chain Decarbonization

Understanding Scope 3 emissions is often the first step toward reducing emissions across the value chain.

Once key emission sources are identified, organizations can work with suppliers and partners to:

• improve supply chain efficiency;
• reduce transport emissions;
• optimize procurement decisions;
• identify lower-carbon alternatives.

Green Analytics supports organizations in transforming supply chain carbon data into actionable climate insights.
