In the race toward sustainability, understanding and addressing Scope 3 emissions is crucial for organizations aiming to meet their environmental goals. Among these, Category 1: Purchased Goods and Services often represents a significant share of emissions. This category includes all upstream emissions from the production of products (both tangible goods and intangible services) purchased by a company during the reporting year.

This blog provides an in-depth exploration of Scope 3 Category 1 emissions, their importance, and actionable strategies for measuring and reducing them effectively.

What Are Scope 3 Category 1 Emissions?

Scope 3 emissions encompass indirect emissions throughout a company’s value chain. Category 1 includes all upstream (cradle-to-gate) emissions from the production of products or services purchased by a company in a given year. These products could include:

• Goods: Raw materials, components, office supplies.
• Services: Outsourced IT support, consulting services, or logistics.

For example, a construction company’s Category 1 emissions might stem from the cement and steel used, while a tech company might focus on emissions from electronic components.

Importance of Category 1 Emissions

Purchased goods and services frequently contribute the majority of Scope 3 emissions. Addressing these emissions not only reduces environmental impact but also enhances compliance with frameworks like the Greenhouse Gas (GHG) Protocol and Science-Based Targets initiative (SBTi).

Bonus: Distinguishing between production-related and non-production-related purchases can simplify data collection and organization.

Why Managing Scope 3 Category 1 Emissions Matters

1. Significant Contribution to Total Emissions

Purchased goods and services represent a substantial share of Scope 3 emissions, often accounting for 40–70% of a company’s total carbon footprint in industries such as manufacturing, retail, and technology. For instance:

• Manufacturing Sector: In heavy manufacturing, emissions from raw material extraction and processing dominate, with steel and cement production alone contributing around 8% of global emissions annually.

• Retail Sector: Large retailers report that Scope 3 emissions from supply chains, particularly from purchased goods like textiles and packaging, make up over 90% of their total emissions.

• Technology Industry: Electronics companies often trace 70% or more of their emissions to upstream suppliers producing semiconductors and other components.

2. Regulatory and Market Pressures

With regulations like the EU’s Corporate Sustainability Reporting Directive (CSRD), Global Reporting Initiative (GRI), Business Responsibility and Sustainability Reporting (BRSR), and increasing investor demand for transparency, addressing these emissions has become a business imperative.

3. Opportunities for Brand Leadership

Companies leading in sustainability gain a competitive edge, attract eco-conscious customers, and improve stakeholder trust.

Challenges in Managing Scope 3 Category 1 Emissions

Managing Scope 3 Category 1 emissions—those associated with purchased goods and services—can be one of the most complex areas of a company’s carbon footprint due to the following challenges:

1. Complex Supply Chains

Many businesses work with multi-tiered suppliers spread across regions, making it difficult to track emissions at every stage. Often, companies have limited visibility into upstream suppliers, particularly those at Tier 2 or beyond.

2. Data Availability and Accuracy

• Suppliers may lack the tools or expertise to provide reliable emissions data.
• Data gaps, particularly for smaller suppliers, lead to reliance on secondary data sources, which may not accurately represent real-world impacts.

3. Standardization and Reporting Issues

• Different industries and geographies follow various methodologies, making it challenging to standardize calculations.
• Compliance with global frameworks like the TCFD or CDP often requires granular data, which many companies find hard to gather.

4. Costs and Resources

Gathering detailed emissions data and engaging suppliers can require significant financial and operational investment, particularly for small- and medium-sized enterprises.

Methods for Measuring Scope 3 Category 1 Emissions

The GHG Protocol outlines four primary methods, each with varying levels of specificity:

1. Supplier-Specific Method

• Relies on product-level cradle-to-gate GHG data provided directly by suppliers.
• Best For: Businesses with strong supplier relationships and robust data collection systems.

2. Hybrid Method

• Combines supplier-specific data with secondary data to fill gaps.
• Example: Collecting supplier Scope 1 and 2 emissions while using average data for upstream processes.

3. Average-Data Method

• Uses secondary data (e.g., industry averages) based on the physical quantity of goods purchased.
• Best For: Large-scale operations with diverse supply chains.

4. Spend-Based Method

• Multiplies the monetary value of goods and services by average emissions factors.
• Best For: Initial screenings or when supplier-specific data is unavailable.

Insight: Companies should use a combination of methods tailored to their business goals and data availability, as highlighted in the Technical Guidance for Calculating Scope 3 Emissions.

Strategies to Reduce Scope 3 Category 1 Emissions

1. Engage Suppliers

• Collaborate with suppliers to identify and reduce emissions within their processes.
• Offer incentives, such as longer-term contracts or shared cost savings, to encourage adoption of low-carbon technologies.

2. Implement Sustainable Procurement Policies

• Embed sustainability criteria into procurement decisions, such as requiring suppliers to meet certifications like ISO 14001 or Fair Trade.
• Shift to suppliers using renewable energy or low-impact raw materials.

3. Conduct Lifecycle Assessments (LCAs)

• Evaluate the full environmental impact of goods and services, from raw material extraction to disposal.
• Use LCAs to prioritize areas for emissions reduction and align sourcing decisions with sustainable goals.

4. Leverage Technology

• Invest in platforms that enable accurate data tracking across supply chains.
• Utilize AI and blockchain tools for real-time monitoring and better transparency.

5. Educate and Train Internal Teams

• Equip procurement and sustainability teams with training on sustainability standards, data management, and green procurement practices.

Benefits of Addressing Scope 3 Category 1 Emissions

1. Regulatory Compliance

Proactively managing emissions ensures compliance with evolving global regulations, such as the EU’s CSRD or the SEC’s climate disclosure rules, reducing legal and financial risks.

2. Enhanced Brand Reputation

Transparency in emissions reporting positions companies as sustainability leaders, fostering trust among customers, investors, and other stakeholders.

3. Operational and Financial Efficiency

• Reducing waste and optimizing resources in procurement processes can lower costs.
• Green innovations may improve efficiency and create a competitive edge.

4. Investor Attraction

Sustainability-focused investors prioritize businesses with robust Scope 3 management strategies, as they signal long-term resilience and commitment to climate goals.

5. Future-Proofing Business Models

Tackling Scope 3 emissions aligns businesses with global climate goals, ensuring relevance in an increasingly eco-conscious market.

Future Trends in Managing Scope 3 Category 1 Emissions

1. Data-Driven Decision Making

• AI and machine learning will play a larger role in analyzing supplier data and identifying hotspots for emissions reduction.
• Advanced analytics tools will offer predictive insights to guide sustainable procurement strategies.

2. Blockchain for Supply Chain Transparency

Blockchain technology will become more prevalent for tracking emissions and verifying supplier compliance, enhancing trust and accountability.
