What Is Greenhouse Gas Emission Audit & Accounting?
Greenhouse Gas Emission Audit and Accounting is the systematic process of identifying, quantifying, recording, and evaluating greenhouse gas emissions associated with an organization’s activities.
GHG accounting involves calculating emissions from sources such as fuel combustion, purchased electricity, industrial processes, refrigerant leakage, transportation, and supply chain operations.
A GHG emissions audit reviews the underlying activity data, emission factors, calculation methods, assumptions, and supporting records to identify potential errors, inconsistencies, or gaps in emissions reporting.
The results help organizations establish a reliable greenhouse gas inventory, monitor emission trends, and identify improvement opportunities.
GHG emissions are generally expressed in tonnes of carbon dioxide equivalent (tCO₂e), allowing different greenhouse gases to be measured and reported using a common unit.
Types of Greenhouse Gas Emissions Covered
GHG accounting typically classifies organizational emissions into three scopes under the GHG Protocol.
Scope 1: Direct GHG Emissions
Emissions released from sources owned or controlled by the organization, including boilers, furnaces, diesel generators, company-operated vehicles, industrial processes, and refrigerant leaks.
Scope 2: Energy-Related Indirect GHG Emissions
Emissions associated with the generation of purchased electricity, steam, heating, or cooling consumed by the organization. Where applicable, calculations address location-based and market-based reporting requirements.
Scope 3: Other Indirect GHG Emissions
Emissions generated across the organization’s value chain, including purchased goods, business travel, employee commuting, outsourced transportation, waste treatment, product use, and other relevant upstream or downstream activities.
Our Greenhouse Gas Emission Audit & Accounting Services

GHG Accounting Standards and Frameworks
Greenhouse gas accounting should be carried out using recognized standards and methodologies that support consistent emissions measurement and reporting.
| Standard / Framework | Application |
| ISO 14064-1:2018 | Organization-level GHG emissions and removals quantification and reporting |
| ISO 14064-3 | Validation and verification of GHG statements |
| GHG Protocol Corporate Standard | Corporate greenhouse gas inventories |
| GHG Protocol Scope 2 Guidance | Purchased electricity and energy-related indirect emissions |
| GHG Protocol Scope 3 Standard | Value chain emissions accounting |

ISO 14064-1 establishes requirements for organizational greenhouse gas inventories, while the GHG Protocol provides widely adopted corporate emissions accounting and reporting methodologies.
Greenhouse Gas Emission Reporting Requirements in India
Greenhouse gas accounting is becoming increasingly relevant to Indian businesses due to climate-related reporting requirements, customer expectations, and developments in the Indian Carbon Market.
Under India’s Carbon Credit Trading Scheme (CCTS), specified obligated entities in energy-intensive sectors are subject to notified greenhouse gas emission intensity targets.
The framework includes emissions monitoring, reporting, and verification requirements for applicable entities. Businesses outside the compliance mechanism may also undertake voluntary greenhouse gas accounting for ESG reporting, supply chain assessments, and internal emission reduction planning.
ConsultHive can assist organizations with GHG inventory preparation, emissions data review, and documentation relevant to their reporting requirements. Where accredited third-party verification is mandatory, it must be performed by an appropriately authorized verification agency.

Frequently Asked Questions About GHG Emission Audit & Accounting
1. What is a greenhouse gas emission audit?
A GHG emission audit is a systematic review of an organization’s greenhouse gas emissions data, calculations, methodologies, and supporting records. It helps identify inconsistencies, reporting gaps, and opportunities to improve the accuracy and reliability of GHG inventories.
2. What is greenhouse gas accounting?
Greenhouse gas accounting is the process of identifying, quantifying, recording, and reporting GHG emissions associated with business activities. It uses recognized methodologies and emission factors to calculate emissions in tonnes of carbon dioxide equivalent.
3. What is the difference between GHG accounting and GHG verification?
GHG accounting involves measuring and reporting emissions. A GHG audit can include an internal or consultant-led review of that information. Independent GHG verification is a separate assurance process conducted by an appropriately qualified verification body against specified criteria.
4. What are Scope 1, Scope 2, and Scope 3 emissions?
Scope 1 includes direct emissions from owned or controlled sources. Scope 2 includes indirect emissions from purchased electricity, heating, steam, and cooling. Scope 3 covers other indirect emissions across upstream and downstream value chain activities.
5. Is GHG emission accounting mandatory in India?
GHG accounting is mandatory for certain entities covered by applicable regulatory requirements, including designated obligated entities under the Carbon Credit Trading Scheme. It is not universally mandatory for all businesses. Organizations may also undertake voluntary GHG accounting to meet customer or sustainability reporting requirements.
6. What documents are required for a GHG emission audit?
Documents commonly include electricity bills, fuel purchase records, equipment details, refrigerant usage records, production data, transportation information, waste management records, and relevant supplier data. Exact requirements depend on the reporting boundaries and emission sources.
7. How frequently should GHG emissions be calculated?
Organizations commonly prepare annual GHG inventories to track emissions performance and support sustainability reporting. The reporting frequency may differ where specific customer, regulatory, or internal requirements apply.
8. Can GHG accounting help an organization reduce emissions?
Yes. GHG accounting helps identify significant emission sources, evaluate energy and fuel consumption patterns, and establish measurable reduction priorities. Actual reductions depend on the improvements implemented and their effectiveness.
9. How long does a GHG emission audit take?
The duration depends on company size, number of operational locations, data availability, emission source complexity, and whether Scope 3 emissions are included. The assessment timeline is determined after reviewing the reporting requirements and proposed audit scope.
10. How much do GHG emission audit and accounting services cost in India?
The cost varies according to the number of facilities, applicable emission scopes, complexity of calculations, availability of supporting data, and reporting requirements. Contact ConsultHive for a quotation based on your organization’s needs.
