GHG Emissions Assessment: A Key Step in Achieving Corporate Sustainability Goals

What is Greenhouse Gas (GHG) Emissions Assessment?

A Greenhouse Gas (GHG) Emissions Assessment is the systematic process of identifying, measuring, and reporting an organization’s direct and indirect greenhouse gas emissions. It is a foundational step in understanding your company’s carbon footprint and aligning with global climate commitments.

GHG emissions are categorized into three scopes:

• Scope 1: Direct emissions from owned or controlled sources (e.g., fuel combustion, company vehicles).
• Scope 2: Indirect emissions from purchased electricity, steam, heating, and cooling.
• Scope 3: All other indirect emissions across the value chain (e.g., purchased goods, transportation, waste, employee commuting)

This assessment follows international standards such as the Greenhouse Gas Protocol, ISO 14064, and national GHG inventory methodologies. The output provides a comprehensive baseline for tracking emissions, identifying carbon hotspots, and developing targeted climate action strategies.

Why GHG Emissions Assessment is Important for Businesses

Whether you're a manufacturer, service provider, or multinational corporation, a verified GHG assessment is critical for the following reasons:

✔ Climate Risk Management

Understanding your GHG emissions helps mitigate physical risks (like extreme weather events) and transitional risks (such as evolving carbon policies and market expectations).

✔ Regulatory Compliance: 

Many countries and regions are adopting climate regulations, including carbon pricing, emission trading systems, and disclosure requirements (e.g., SEC Climate Rules, CSRD, TCFD). GHG assessments ensure your business is compliant and future-ready.

✔ Reputation and Market Differentiation

Transparent GHG reporting enhances corporate reputation and appeals to investors, customers, and employees focused on ESG performance.

✔ Strategic Decision-Making

A robust GHG inventory supports data-driven decisions on energy efficiency, renewable sourcing, and supply chain optimization.

✔ Foundation for Climate Targets

A credible emissions baseline is the first step toward setting Science-Based Targets (SBTs), Net Zero commitments, or climate-neutral certifications.

Benefits of Conducting GHG Emissions Assessment

• Credible Sustainability Reporting:  GHG data forms the core of ESG reports and enables companies to respond confidently to sustainability disclosures and frameworks such as CDP, GRI, and SASB.
• Resource Efficiency and Cost Savings: Identifying emissions hotspots often leads to uncovering energy inefficiencies, reducing operational costs, and improving resource management.
• Investor Confidence: Investors increasingly demand climate-related disclosures. GHG assessments demonstrate corporate accountability and risk readiness.
• Supply Chain Transparency: Scope 3 analysis promotes collaboration with suppliers and customers to reduce upstream and downstream emissions.
• Climate Leadership: Early action on emissions sets companies apart as industry leaders and responsible global citizens.
   

Steps to Conduct GHG Emissions Assessment

• Define Organizational and Operational Boundaries: Determine which business units, facilities, and processes are included using the control or equity share approach.
• Identify Emission Sources: List all emission sources under Scopes 1, 2, and 3. This includes everything from fuel usage to purchased goods and business travel.
• Collect Activity Data: Gather data such as fuel consumption, energy bills, production metrics, and transport logs for the reporting period.
• Apply Emission Factors: Convert activity data to GHG emissions using recognized emission factors from IPCC, EPA, or national inventories.
• Calculate Emissions: Calculate emissions for each scope. Typically reported in metric tons of CO₂-equivalent (tCO₂e).
• Verify and Validate: (Optional but recommended) Third-party verification enhances accuracy, credibility, and trust.
• Report and Use Results: Disclose emissions in sustainability reports or regulatory filings and use results to develop reduction strategies or apply for SBTi, net-zero labels, etc.
