ISO 14064-1 Carbon Footprint

Frequently Asked Questions: 

• What is ISO 14064-1?

  ISO 14064-1 is the international standard for measuring, quantifying, reporting and managing an organisation's greenhouse gas (GHG) emissions. It provides a recognised framework for developing a carbon footprint by calculating Scope 1, Scope 2 and, where applicable, Scope 3 emissions. Implementing ISO 14064-1 helps organisations improve the accuracy of their emissions reporting, support sustainability objectives and prepare for independent verification or broader ESG reporting requirements. 

• What is the difference between ISO 14064-1 and the GHG Protocol?

  Both ISO 14064-1 and the GHG Protocol provide frameworks for measuring greenhouse gas emissions, but they serve slightly different purposes. The GHG Protocol is widely used as an accounting methodology for calculating emissions, while ISO 14064-1 is an internationally recognised management standard that establishes requirements for quantifying, reporting and managing organisational greenhouse gas inventories. Many organisations use the GHG Protocol alongside ISO 14064-1 to strengthen the accuracy and credibility of their carbon reporting. 

• Who should implement ISO 14064-1?

  ISO 14064-1 is suitable for organisations of all sizes and sectors that want to understand and manage their greenhouse gas emissions. It is particularly valuable for businesses responding to customer sustainability requirements, preparing ESG or voluntary sustainability reports, pursuing Net Zero goals, participating in public procurement, or improving environmental performance through internationally recognised best practice.

• What are Scope 1, Scope 2 and Scope 3 emissions?

  ISO 14064-1 categorises greenhouse gas emissions into different sources. Scope 1 emissions are direct emissions from sources owned or controlled by your organisation, such as company vehicles or fuel combustion. Scope 2 emissions are indirect emissions from purchased electricity, heating or cooling. Scope 3 emissions include other indirect emissions across your value chain, such as purchased goods, business travel, waste and employee commuting. Measuring all relevant emission sources provides a more complete understanding of your organisation's carbon footprint. 

• Is ISO 14064-1 certification mandatory?

  No. ISO 14064-1 certification is not a legal requirement, but implementing the standard can provide significant commercial and strategic advantages. Organisations increasingly use ISO 14064-1 to demonstrate credible carbon reporting, meet customer expectations, strengthen ESG disclosures, support Net Zero commitments and prepare for independent greenhouse gas verification. 

• How long does it take to implement ISO 14064-1?

  The time required to implement ISO 14064-1 depends on the size and complexity of the organisation, the availability of emissions data and the maturity of existing sustainability processes. Many organisations can establish a compliant greenhouse gas inventory within a few months, while larger or more complex organisations may require additional time to collect data, calculate emissions and prepare for verification.  

• What information is needed to calculate an organisational carbon footprint?

  Developing an ISO 14064-1 greenhouse gas inventory typically requires data on fuel consumption, electricity usage, refrigerants, business travel, waste generation, water consumption and other relevant operational activities. Depending on the reporting boundary, organisations may also collect supply chain and procurement data to calculate Scope 3 emissions. Accurate and complete data improves the reliability of carbon reporting and supports future reduction initiatives.

• Can ISO 14064-1 support ESG and sustainability reporting?

  Yes. ISO 14064-1 provides a robust framework for producing accurate greenhouse gas data that can support ESG reporting, voluntary sustainability reporting, customer disclosures and climate-related reporting initiatives. Reliable emissions data also helps organisations demonstrate transparency, monitor progress towards environmental objectives and build stakeholder confidence. 

• Can small and medium-sized businesses implement ISO 14064-1?

  Yes. ISO 14064-1 is suitable for organisations of all sizes, including SMEs. The standard can be applied proportionately, allowing smaller organisations to establish a structured greenhouse gas inventory without unnecessary complexity. Many SMEs implement ISO 14064-1 to meet customer expectations, improve sustainability performance and gain a competitive advantage in procurement opportunities. 

• Does ISO 14064-1 help organisations achieve Net Zero?

  ISO 14064-1 does not certify an organisation as Net Zero, but it provides the essential foundation for any credible Net Zero strategy. By accurately measuring greenhouse gas emissions and establishing a reliable baseline, organisations can identify reduction opportunities, monitor progress over time and develop evidence-based carbon reduction plans that support long-term climate goals.
