8 best software solutions to implement ISO 14064

ISO 14064 has become the leading international standard for quantifying, managing and reporting greenhouse gas (GHG) emissions. Its adoption is no longer merely optional: it is one of the elements that underpin decarbonisation strategies, the independent verification of inventories and the transparent disclosure of results to clients, investors and regulators.

Implementing ISO 14064 involves far more than simply adding up emissions: it requires traceability, methodological consistency and a reliable data structure, especially for organisations preparing for external audits or aligning their reporting with frameworks such as the CSRD, the European Green Deal or sector-specific low-carbon initiatives.

In this article we analyse the best software for implementing ISO 14064, what a tool must include to guarantee technical compliance and which international solutions are best suited to different types of organisations, with Manglai leading the ranking for its methodological approach, its alignment with the standard and its ability to automate critical reporting processes.

What is ISO 14064 and why is it essential to corporate sustainability strategy?

ISO 14064 is the standard that defines the requirements for quantifying and reporting GHG emission inventories in a verifiable manner. Unlike more narrative-based standards, ISO 14064 establishes structured criteria, including:

• Organisational and operational boundaries.
• Methodologies for calculating direct and indirect emissions.
• Uncertainty management.
• Data quality controls.
• Requirements for independent verification.

Today, its relevance is decisive for three main reasons:

1. It underpins many regulated sustainability reports: numerous companies use it as the technical foundation for CSRD and ESRS compliance.
2. It enables reliable external audits: verification bodies generally require inventories built under ISO 14064 to issue assurance.
3. It standardises climate communication: it establishes a common language that helps reduce the risk of greenwashing.

If you want to explore how to communicate these results, we recommend our article on how to communicate your decarbonisation strategy and avoid greenwashing.

How to choose the best ISO 14064-compatible software

Selecting the right software to implement ISO 14064 is a strategic decision that directly affects inventory accuracy, reporting quality and the ability to pass external audits smoothly.

Not all tools on the market provide the traceability, methodological rigour or regulatory alignment the standard requires, so comparing functionalities, data sources and verification capabilities is essential.

These are the six criteria any ISO 14064-compatible software should meet:

1. Strict methodological alignment: it must reflect the principles of the standard: relevance, completeness, consistency, transparency and accuracy. The most advanced tools translate these principles into guided workflows, automated controls and validated templates.

2. Data quality and access to emission factors: the system should integrate up-to-date libraries (IPCC, IEA, sector-specific databases) and allow auditable custom emission factors.

3. Scalability: an effective tool must support growth from a basic inventory to multinational operations with dozens of sites, fleets and processes.

4. Calculation automation: automation reduces manual errors and supports consistency over time. Leading platforms provide full traceability from raw activity data to the final result.

5. Verifiable reporting: ISO 14064 requires clear documentation, annexes, inventory boundaries and methodological notes. The tool must generate reports that meet these audit requirements.

6. Integration with other frameworks: especially the GHG Protocol, ESRS E1, ISO 14067 and sector-specific requirements (logistics, industry, food, etc.).

What is the best software to implement ISO 14064?

Choosing the best software to implement ISO 14064 is a decisive step for any organisation seeking to build a reliable, verifiable GHG inventory aligned with international standards.

The quality of the tool determines calculation accuracy, data traceability and how easily the company can pass external audits or report under frameworks such as the CSRD or the GHG Protocol.

In an increasingly fragmented market, identifying which platforms truly meet ISO 14064 requirements, and which only offer partial calculations, is essential to avoid methodological errors and wasted time.

In this section we analyse the most robust solutions on the market, with Manglai at the top, for its regulatory approach, its automated workflows and its ability to generate verifiable reports.

How to start implementing ISO 14064

Starting ISO 14064 implementation requires a structured approach that ensures methodological consistency from day one.

While many companies begin by collecting data without a clear framework, the standard requires defining boundaries, data quality criteria, information sources and verification procedures before performing any calculation. Taking the first steps in an orderly way not only reduces errors and rework but also accelerates audit readiness and facilitates alignment with other regulatory frameworks such as the CSRD or the GHG Protocol.

Below, we guide you through the essential phases to begin implementing ISO 14064 with confidence, clarity and efficiency in your corporate sustainability strategy:

1. Define the purpose of the inventory: the standard requires clarity on the purpose, whether it is regulatory compliance, tenders, CSRD reporting, customer requirements or an internal decarbonisation plan.

2. Establish the organisational boundaries: determine whether the inventory covers operational control, financial control, equity share or a combination.

3. Collect the structural data: including energy consumption, mobility and logistics, processes, procurement, waste and water, and fugitive emissions. This is where software can notably reduce the time involved.

4. Calculate emissions and generate the documentation: the software should create methodological notes, technical annexes, source descriptions and category-level indicators.

5. Prepare for independent verification: the standard requires strict traceability. Good software makes it easier to manage evidence, primary sources, intermediate calculations and version history.

Frequently asked questions about the best software for implementing ISO 14064

Do I need software to become ISO 14064 certified?

It is not strictly mandatory, but it helps considerably, since audits require traceability, structured documentation and verifiable records. Doing it with spreadsheets alone increases the risk of errors and makes version control harder.

What is the difference between ISO 14064 and the GHG Protocol?

The GHG Protocol defines principles and categories, while ISO 14064 defines the method and the verifiable requirements. In practice, many companies combine the two.

Is it mandatory to audit my inventory?

Not always, although it is usually essential for regulated sustainability reporting, public tenders and negotiations with large clients.

Can ISO 14064 be extended to suppliers?

Yes, and a growing number of companies require it. Manglai, for example, allows supplier inventories to be added within the same ecosystem.
