Full title and description

ISO 14064-2:2019 — Greenhouse gases — Part 2: Specification with guidance at the project level for quantification, monitoring and reporting of greenhouse gas emission reductions or removal enhancements. This standard specifies principles, requirements and guidance for planning, quantifying, monitoring and reporting the GHG effects of specific projects intended to reduce emissions or enhance removals.

Abstract

ISO 14064-2:2019 provides the project-level framework for identifying relevant sources, sinks and reservoirs (SSRs), establishing a baseline scenario, quantifying project and baseline emissions/removals, monitoring performance, managing data quality and documenting and reporting project-level GHG emission reductions or removal enhancements. It is programme-neutral and intended to support transparent, consistent and verifiable project-level GHG accounting.

Scope

This part of ISO 14064 specifies principles and requirements and provides guidance at the project level for the quantification, monitoring and reporting of activities intended to cause greenhouse gas emission reductions or removal enhancements. It covers project planning, selection of SSRs, baseline scenario development, monitoring, quantification, documentation and reporting of project performance and data quality management. The standard is programme-neutral — any additional requirements from a GHG programme would be applied alongside ISO 14064-2.

Key topics and requirements

• Project boundary definition and selection of relevant sources, sinks and reservoirs (SSRs).
• Baseline scenario development and requirements for demonstrating additionality (establishing what would have occurred without the project).
• Quantification methodologies for project and baseline emissions/removals, including conservative assumptions where appropriate.
• Monitoring plans and requirements for data collection, frequency and quality control.
• Accounting for leakage and interactions outside the project boundary.
• Documentation, transparent reporting and record-keeping to support third‑party verification.
• Guidance on managing data quality and uncertainty to ensure consistent, reproducible results.

Typical use and users

ISO 14064-2 is used by project developers, consultants, verification and certification bodies, registries, carbon programme administrators, auditors, and government or corporate sustainability teams that design, quantify or validate GHG reduction/removal projects (e.g., renewable energy, energy efficiency, methane capture, forestry and land‑use projects). It supports project-level accounting to enable robust reporting, stakeholder transparency and third‑party verification.

Related standards

ISO 14064-2 is part of the ISO 14064 family. Closely related standards include ISO 14064-1 (organizational-level quantification and reporting) and ISO 14064-3 (validation and verification of GHG assertions). Other related standards and guidance include ISO 14065, ISO 14066 and product or programme-specific guidance on GHG accounting.

FAQ

Q: What is this standard?

A: ISO 14064-2:2019 is the project‑level part of the ISO 14064 family that specifies principles and guidance for quantifying, monitoring and reporting greenhouse gas emission reductions and removal enhancements associated with specific projects.

Q: What does it cover?

A: It covers project planning, defining project boundaries and relevant SSRs, baseline development (including additionality considerations), quantification methods, monitoring plans, data quality management, reporting and documentation to support independent verification.

Q: Who typically uses it?

A: Project developers, environmental consultants, verification/validation bodies, carbon registries, programme administrators, auditors and corporate or public sector teams involved in designing and reporting GHG reduction/removal projects.

Q: Is it current or superseded?

A: The 2019 second edition is the current published version; ISO indicates the edition was published in April 2019 and was reviewed and confirmed current in ISO’s periodic review process (confirmation noted in 2024). The 2006 edition was withdrawn and replaced by the 2019 edition.

Q: Is it part of a series?

A: Yes — ISO 14064-2 is part of the ISO 14064 series. Related parts include ISO 14064-1 for organizational accounting and ISO 14064-3 for validation and verification of GHG assertions; additional complementary standards cover verifier competence and conformity assessment.

Q: What are the key keywords?

A: Keywords include greenhouse gases (GHG), project-level accounting, emission reductions, removal enhancements, baseline, additionality, monitoring, verification, leakage and ISO 14064.
