Participants completing the programme will be able to:

• Understand the structure and logic of organisational GHG inventories
• Review organisational GHG inventories for methodological consistency
• Evaluate Scope 1, Scope 2, and Scope 3 emissions calculations
• Evaluate emission factor selection and calculation methods
• Identify risks in Scope 3 data collection approaches
• Identify inconsistencies and risks in emissions data and documentation
• Assess data quality, completeness, and traceability
• Assess documentation supporting reported emissions
• Apply verification planning techniques and sampling approaches
• Conduct structured verification reviews of emissions reports
• Prepare structured verification findings, observations, and improvement recommendations

The training runs as an intensive professional programme combining:

• Conceptual foundations of greenhouse gas accounting
• Verification methodologies and principles
• Data quality assessment and documentation review
• Industry-focused case studies
• Practical examples of emissions inventory evaluation

Training can be run:

• Remotely, as live online sessions
• On-site at the client location
• Off-site in Japan

Organisations and professionals often face challenges such as:

• Lack of internal expertise to evaluate GHG inventories
• Difficulty assessing Scope 3 emissions data reliability
• Limited understanding of verification workflows
• Inconsistent documentation supporting emissions calculations
• Increased regulatory scrutiny around emissions reporting
• Growing demand for credible emissions disclosure

The training references key frameworks used in greenhouse gas accounting and verification:

• GHG Protocol — Corporate Standard
• ISO 14064 — greenhouse gas accounting framework
• Verification planning — principles of planning and review
• Risk-based approaches — risk-based verification methods
• Data quality — data quality management principles

The focus is methodological interpretation and practical verification workflows, letting participants evaluate real-world emissions inventories. DEISO is not a certification or verification body; the training covers how these standards are applied and reviewed.

Practical case studies illustrate verification challenges in major industrial sectors:

• Oil and gas industry
• Chemical manufacturing
• Cement and construction materials
• Electronics manufacturing

These case studies show common issues encountered in emissions accounting and verification.

The programme is built for professionals working in:

• Sustainability and climate reporting teams
• Environmental and carbon accounting departments
• Industrial environmental management roles
• Consulting firms providing climate advisory services
• Corporate ESG and sustainability teams
• Research roles working on climate and emissions analysis

Industries that benefit most include:

• Oil and gas
• Chemicals
• Manufacturing
• Energy
• Industrial supply chains

The programme can be run in three formats:

The certificate recognises completion of the DEISO training programme and the associated assessment. It is not a formal accreditation, and DEISO is not a certification or verification body.

Participants may choose to take an optional examination after completing the training. The assessment covers understanding of greenhouse gas accounting principles, emissions inventory development, and verification methodologies.

The examination focuses on the ability to:

• Interpret and evaluate organisational GHG inventories
• Assess Scope 1, Scope 2, and Scope 3 emissions calculations
• Review emissions data sources, documentation, and traceability
• Identify inconsistencies and methodological issues in emissions reporting
• Apply structured verification principles and review procedures

The option is open to participants attending remote, on-site, or off-site sessions. Examination and certificate fees are charged separately.

The programme builds capability in greenhouse gas accounting review, emissions inventory evaluation, and climate reporting assessment. Participants may apply these competencies in roles such as:

• GHG inventory reviewer — evaluate greenhouse gas inventories prepared by organisations and assess data quality, methodological consistency, and completeness of reported emissions
• Carbon accounting specialist — support organisations in reviewing Scope 1, Scope 2, and Scope 3 emissions calculations and improving internal carbon accounting practices
• Climate reporting analyst — assist sustainability and ESG teams in evaluating emissions disclosures and strengthening the credibility of climate-related reporting
• Environmental verification professional — review emissions documentation, assess calculation methodologies, and identify risks or inconsistencies in reported emissions data
• Sustainability consultant — advise organisations on greenhouse gas reporting systems, emissions accounting frameworks, and improvements to carbon management practices

DEISO runs specialised professional training in sustainability, life cycle assessment, and greenhouse gas management.

The training is built and run by experienced sustainability professionals with expertise in environmental assessment methodologies and industrial sustainability analysis.

Organisations that have taken part in DEISO training programmes include companies and institutions across the energy, industrial, and academic sectors.
