Carbon Accounting

Carbon accounting represents the processes and methods used to quantify and track greenhouse gas emissions and carbon removal activities, serving as a crucial foundation for climate action and emissions management.

Core Principles

Scope Classification

Carbon accounting typically divides emissions into three scopes:

1. Scope 1: Direct emissions

   • On-site fossil fuel combustion
   • Company vehicle emissions
   • industrial processes

2. Scope 2: Indirect energy emissions

   • Purchased electricity consumption
   • Steam and heating
   • Cooling systems

3. Scope 3: Other indirect emissions

   • Supply chain activities
   • business travel
   • waste management
   • Employee commuting

Methodologies

Standard Frameworks

Several internationally recognized frameworks guide carbon accounting practices:

• GHG Protocol
• ISO 14064 Standards
• carbon disclosure frameworks
• environmental reporting guidelines

Calculation Approaches

1. Direct Measurement

   • Continuous emissions monitoring
   • sensor networks
   • Point source testing

2. Activity-Based Calculations

   • Emission factors
   • energy consumption data
   • carbon intensity metrics

Implementation

Organizational Level

Organizations implement carbon accounting through:

1. Data Collection

   • Utility records
   • fuel consumption tracking
   • supply chain assessments

2. Analysis and Verification

   • Third-party audits
   • Internal reviews
   • data validation

Product Level

Product-specific carbon accounting includes:

• lifecycle assessment
• carbon footprint calculation
• product certification
