ISO 14064-1 Carbon Footprint Verification

ISO 14064-1 Standard includes the principles and requirements on calculation and reporting of greenhouse gas emissions and their removals at the level of establishment. This standard also includes the conditions required for the design, improvement, management, reporting and verification of greenhouse gas inventory of an establishment.

The serie of ISO 14064 Standards is an impartial greenhouse gas program. The requirements of this greenhouse gas program are the continuation of the conditions within the serie of ISO 14064 Standards, when a greenhouse gas program is implemented.

The condition of greenhouse gas program is given priority, in case where  one of the clauses of ISO 14064 Standards’ serie forbids an establishment or a project partner to fulfill a condition of greenhouse gas program.

a- Concepts

Greenhouse Gas: Both natural and anthropogenic gas component of atmosphere that is absorbed and released at certain wavelength by the atmosphere and clouds at the infrared radiation spectrum range. Greenhouse gases taken into considertation in calculations within the scope of ISO 14064 standard (CO2, CH4, N2O, HFCS, PFCS, SF6);

Greenhouse Gas Source: A physical unit or process that releases greenhouse gase into the atmosphere.

Greenhouse Gas Sink: A physical unit or process that removes any of the greenhouse gases from the atmosphere.

Greenhouse Gas Reservoir: A physical unit or component for the biosphere’s, geosphere’s or hydrosphere’s storage or accumulation capacity of a greenhouse gas removed from the atmosphere by a greenhouse gas sink or a greenhouse gas retained by a greenhouse gas source.

Greenhouse Gas Emission: The total mass of one of the greenhouse gases released into the atmosphere within a certain period of time.

Greenhouse Gas Removal: The total mass of one of the greenhouse gases removed from the atmosphere within a certain period of time.

Greenhouse Gas Emission and Removal Factor: The factor on activity data carried out for greenhouse gas emissions or removals.

Direct Greenhouse Gas Emission (Scope 1): Greenhouse gas emission released from greenhouse gas sources owned or controlled by our establishment (financial and operational).

Energy-Indirect Greenhouse Gas Emission (Scope 2): Greenhouse gas emission occurring during the manufacturing of the electricity, heat or steam that is externally procured and consumed by our establishment.

Other-Indirect Greenhouse Gas Emission (Scope 3): Greenhouse gas emission resulting from greenhouse gas sources owned or controlled by other establishments as a result of activities of an establishment apart from energy-indirect greenhouse gas emissions.

Greenhouse Gas Activity Data: Quantitative measurement of an activity ending up with a greenhouse gas emission or its removal.

Effect potency on global warming (EPGW): Identifying factor of power effect of a certain type of mass-based greenhouse gas in terms of equivalent carbon dioxide at a certain period of time.

Carbon Dioxide Equivalent (CO2e): The unit used in comparing radiation power of a greenhouse gas with carbon dioxide.

Target User: Individual or establishment whose information on greenhouse gas has been defined by the reporting bodies and that relies on this information in making decision.

Guided Activity: Special activity or initiative that has not been designed as a greenhouse gas project and is implemented by an establishment so as to reduce or hinder direct or indirect greenhouse gas emissions or increase greenhouse gas removals.

Confidence Level: The confidence level demanded by the target user in certification or verification.

Base Year: A period at past specified for the greenhouse gas emissions or removals or information on greenhouse gas to be compared in the future.

b- Determination of establishment Borders

The establishment may consist of one facility or more facilities. Greenhouse gas emissions or removals at facility level can be formed via one greenhouse gas source or more or sinks.

The establishment should combine one of the following approaches with greenhouse gas emissions and removals at facility level:

  1. a) Control: The establishment is liable at all the calculated greenhouse gas emissions and/or removals of the facilities under its financial and administrative control.
    b) Equal Sharing: The establishment is liable at all parts of greenhouse gas emissions and/or removals of the relevant facilities.

c- Determination of Activity Limits

The  establishment should determine and document its activity limits. Determination of activity limits should include identification of greenhouse gas emissions and their removals related to the practices of the establishment and classification of greenhouse gas and their removals as direct emissions (scope 1 mandatory), energy-indirect emissions (scope 2 mandatory) and other-indirect emissions (scope 3 not mandatory). Furthermore; this case includes selecting which other-indirect emissions shall be calculated and reported.

d- Doing The Calculations

The  establishment should determine and document greenhouse gas sources that directly contribute to greenhouse gas emissions (Mobile & Stable Combustion, Fugitive Emissions, Process Emissions, …). The establishment should separately document the suppliers of electricity, heat or steam that it has imported and consumed. The establishment should separately identify and document greenhouse gas sources contributing into other-indirect greenhouse gas emissions, while calculating other-indirect greenhouse gas emissions.

The establishment should separately determine calculation methodology compatible to itself, make a decision on the base year, collect activity data and make decision on Emission Factors (EF), Net Calorific Value (NCV), Effect Potency on Global Warming (EPGW) and other components that may affect the calculation (Oxidation Factor, Density, Cycles…)

e- Reporting

The establishment should prepare a greenhouse gas report so as to facilitate the greenhouse gas inventory to be verified and participation into greenhouse gas program or notify external or internal users. Greenhouse gas reports should be complete, coherent, accurate, relevant and transparent. The establishment should determine the content and structure of greenhouse gas reports, accessibility of the public and announcement methods based on the requisits of the applicable greenhouse gas program, requirements of internal reporting and needs of report’s target users.

The establishment should enable greenhouse gas report prepared as required by the third party’s verifying explanation on the standard or greenhouse gas statement to be accessed by the public, in case where it prepared a public greenhouse gas statement claimed to be compatible with this standard. Verifying statement should be made to the target users, if the greenhouse gas statement of the establishment has been independently verified.

f- Verifying establishment Selection

Overall aim of the verification is that the reported greenhouse gas emissions and removals or greenhouse gas statement shall be independently and objectively reviewed. QSI verifies the Greenhouse Gas Emission Reports prepared in accordance with the ISO 14064-1 based on the ISO 14065 accreditation standard with its expert staff.
