Why Distinguishing Between Different Types of Greenhouse Gas Emissions Matters for Your Climate Risk Strategy

As climate disclosure requirements evolve globally, understanding the critical difference between direct operational carbon emissions and supply chain greenhouse gas emissions has become essential for accurate financial climate risk assessment. This distinction is not merely a reporting technicality—it fundamentally affects how companies measure, manage, and monetize their environmental impact.

The Growing Importance of Carbon Emission Classification in Financial Reporting

With stringent regulations such as the EU's Corporate Sustainability Reporting Directive (CSRD) and the SEC's proposed climate disclosure rule, organizations must now provide comprehensive greenhouse gas (GHG) emissions data as part of their financial reporting. The challenge lies in ensuring this information accurately represents financial climate risk without double-counting or misattribution across global value chains.

Operational Environmental Cost: Quantifying Direct Climate Exposure

Operational carbon emissions—those directly attributable to a company's activities—form the foundation of measurable and financially material climate risk. These emissions fall into two categories under the GHG Protocol:

  • Scope 1 Emissions: Direct greenhouse gas emissions from company-owned or controlled sources, including:
    • Manufacturing facilities
    • Company vehicle fleets
    • On-site fuel combustion
    • Industrial processes
  • Scope 2 Emissions: Indirect carbon emissions from purchased energy, including:
    • Electricity consumption
    • Steam, heating, and cooling
    • Purchased energy for operational use

These operational emissions represent the core component of a company's carbon footprint that translates directly into financial climate risk. They are integrated into climate-adjusted financial metrics such as environmental-adjusted EBITDA or P&L statements. Because these emissions are under direct company control, they provide a standardized basis for cross-industry comparison and benchmarking of carbon intensity.

Scope 3 Emissions: Measuring Supply Chain Climate Risk

Scope 3 emissions encompass all indirect greenhouse gas emissions that occur throughout a company's value chain—both upstream and downstream. While not directly controlled by the reporting company, these emissions often constitute the largest portion of an organization's total carbon footprint and represent significant financial climate risk exposure.

Scope 3 greenhouse gas emissions include:

  • Purchased goods and services (embodied carbon)
  • Business travel and employee commuting
  • Transportation and distribution networks
  • Use of sold products throughout their lifecycle
  • Waste disposal and end-of-life treatment of products
  • Investments and financing activities

Exposure to these value chain emissions can translate into financial risk through multiple channels:

  • Increased supplier costs due to carbon pricing mechanisms
  • Energy price volatility across the supply chain
  • Evolving regulatory requirements for comprehensive emissions reporting
  • Changing investor expectations regarding carbon management
  • Consumer demand for lower-carbon products and services

For instance, in EcoMap's analysis of the shipping sector, Scope 3 emissions account for over 80 percent of total climate exposure across the value chain. However, Scope 1 and 2 remain the primary drivers of direct operational climate cost, carbon tax exposure, and regulatory compliance requirements.

Why Separate Reporting of Carbon Emission Scopes Is Essential

While Scope 3 emissions are critical for understanding a company's complete greenhouse gas inventory and carbon footprint, incorporating them directly into operational P&L metrics would result in systemic double-counting across the economy. For example:

  • Carbon emissions from steel production would appear as Scope 1 for the steel manufacturer
  • The same emissions would then reappear as Scope 3 for every company using that steel
  • This cascading effect would artificially inflate the total calculated environmental cost

To maintain financial clarity and enable meaningful carbon accounting, emissions should be reported separately by scope. This approach ensures:

  • Clear attribution of greenhouse gas responsibility
  • Transparent assessment of supply chain climate risk exposure
  • Prevention of carbon emission double-counting in financial metrics
  • Standardized climate risk comparisons across industries, sectors, and regions
  • Alignment with global emissions reduction targets and net-zero strategies

An Integrated Approach to Carbon Emissions and Financial Climate Risk

A comprehensive framework for financial climate risk analysis should:

  1. Monetize Scope 1 and 2 emissions as direct Operational Environmental Cost
  2. Quantify Scope 3 emissions separately as supply chain exposure
  3. Avoid double-counting to enable reliable carbon benchmarking
  4. Provide financial-grade climate data for stakeholders across the investment chain
  5. Support climate risk disclosure aligned with regulatory requirements
  6. Enable targeted carbon reduction strategies where they matter most

This structured approach ensures that environmental data can be applied to financial decision-making with confidence and consistency, creating a foundation for effective climate risk management and authentic sustainability leadership.

Take Action on Your Organization's Carbon Footprint

Understanding your organization's greenhouse gas emissions across all scopes is the first step toward effective climate risk management. By accurately classifying, measuring, and addressing your carbon emissions, you can:

  • Identify your most significant sources of climate risk exposure
  • Develop targeted emission reduction strategies
  • Meet evolving regulatory disclosure requirements
  • Respond to investor and stakeholder expectations
  • Position your organization for success in a carbon-constrained economy
