Preparing for Reasonable Assurance

Methane emissions are under increasing scrutiny from regulators and investors, particularly in the Oil & Gas sector. With the introduction of the EU Methane Regulation and growing expectations for credible, decision-useful disclosures, many organizations are moving beyond limited assurance toward reasonable assurance. This significantly raises expectations for data quality, documentation, controls, and auditability.

This private workshop is designed for intact teams, enabling cross-functional alignment and practical discussion tailored to your organization’s methane reporting approach. It provides a practical, low-risk environment to understand how your current framework stands up to the higher bar of reasonable assurance.

Delivered as an interactive working session, participants bring their current approaches, challenges, and edge cases. The facilitator applies an assurance lens, based on real audit expectations, to help teams identify gaps, clarify requirements, and strengthen their readiness.

By the end of the session, your team will have a clear view of what assurance providers look for, where your risks lie, and how to take immediate steps to improve.

About the Workshop

Methane emissions assurance is becoming a critical component of regulatory compliance, investor confidence, and corporate credibility. Organizations must demonstrate not only accurate reporting, but also robust processes, traceable data flows, and defensible methodologies.

Led by experienced assurance practitioners, this workshop combines:

• Practical insights from real methane assurance engagements
• Interactive discussions tailored to your organization’s setup
• Hands-on readiness evaluation using a structured framework

Participants will leave with a clear understanding of how methane disclosures are evaluated under reasonable assurance, along with practical tools to strengthen alignment across operations, sustainability, engineering, IT, and reporting functions.

Learning Objectives

This workshop equips participants with both conceptual understanding and practical tools to prepare for methane emissions reasonable assurance.

By the end of the session, you will be able to:

• Explain what reasonable assurance is and how it differs from limited assurance
• Understand how methane emissions are assessed under assurance engagements
• Interpret the regulatory and market drivers increasing methane scrutiny
• Identify common audit risk areas in methane emissions reporting
• Conduct a structured internal self-assessment using an assurance lens
• Strengthen alignment across operational, sustainability, engineering, IT, and reporting teams

Who Should Attend

This workshop is designed for professionals involved in methane emissions data, reporting, and assurance preparation:

• Methane emissions teams responsible for measurement, estimation, and reporting
• Sustainability and ESG leads preparing regulatory and investor disclosures
• Operational data owners managing methane data systems and workflows
• Environmental engineers supporting emissions quantification
• IT and data leads responsible for reporting infrastructure and data integrity
• Internal audit, risk, or assurance coordinators preparing for external review

How does this workshop add value?

Workshop Highlights

Assurance Fundamentals

• Materiality in methane emissions disclosures
• The difference between data validation and verification
• Key distinctions between limited and reasonable assurance and their impact on evidence requirements

 Regulatory and Market Context for Methane Emissions

• Drivers of increasing methane regulation globally, including EU requirements
• Why methane presents unique assurance challenges, including:
  • High estimation uncertainty
  • Multiple measurement methodologies
  • Reconciliation challenges between top-down and bottom-up data
• What stakeholders expect from credible, decision-useful disclosures
• The role of independent assurance in reducing regulatory and reputational risk

What to Expect in a Methane Emissions Assessment

Participants will be walked through the typical structure and flow of a methane‑focused Reasonable Assurance assessment, including:

• Review of data sources, boundaries, methodologies, and controls
• Evaluation of documentation and audit trails
• Interviews with key stakeholders and data owners
• Typical findings from methane readiness and assurance engagements
• Differences between readiness assessments, limited assurance, and reasonable assurance

The Assurance Readiness Framework

The workshop introduces a structured framework to evaluate preparedness across five Assurance Readiness Pillars (ARPs):

• Data
• Process
• Technology
• Documentation
• People

This framework provides a clear, actionable way to assess current maturity and prioritize improvements.

Duration & Format

Format: Private, facilitator-led workshop for teams (virtual and/or in-person)

This workshop is delivered exclusively for organizational teams, allowing participants to work through real methane reporting processes, data flows, and challenges together.

During this interactive working session, your team will compare current practices against assurance expectations, raise real scenarios, and receive direct, experience-based guidance tailored to your organization.

Materials

Participants will receive access to workshop materials following the session, enabling continued use as teams work through identified gaps and strengthen their methane assurance readiness over time.

Frequently Asked Questions (FAQ)

Is this workshop delivered publicly or privately?

This is a private workshop delivered exclusively for your organization’s team. It is designed to bring together cross-functional stakeholders (e.g., sustainability, operations, engineering, IT, and audit) to align on methane emissions reporting and assurance readiness in a practical, confidential setting.

What is reasonable assurance for methane emissions?

Reasonable assurance is the highest level of independent verification applied to emissions data. It requires detailed testing of data, controls, and processes, providing stakeholders with a high degree of confidence in the accuracy and completeness of methane disclosures.

Why is methane emissions assurance becoming more important?

Methane is a high-impact greenhouse gas and a growing focus of regulation and investor scrutiny. Frameworks such as the EU Methane Regulation are increasing expectations for transparent, high-quality disclosures supported by robust assurance.

How is reasonable assurance different from limited assurance?

Limited assurance relies primarily on analytical review and inquiry, providing moderate confidence. Reasonable assurance involves extensive evidence gathering, control testing, and validation, resulting in a significantly higher level of rigor and assurance.

Who should attend this workshop?

This workshop is designed for cross-functional teams involved in methane emissions reporting, including sustainability leads, engineers, data owners, IT teams, and internal audit or assurance coordinators.

Why is a team-based workshop important for methane assurance?

Methane reporting relies on multiple functions, including operations, engineering, sustainability, IT, and governance. A team-based workshop ensures alignment across these groups, helping to identify gaps, clarify responsibilities, and reduce friction during assurance engagements.

How will this workshop help my organization prepare?

The workshop applies an assurance lens to your current methane reporting approach, helping your team identify gaps in data, processes, controls, and documentation. You will leave with clear, actionable steps to improve readiness for assurance.

What are the Assurance Readiness Pillars?

The Assurance Readiness Pillars (Data, Process, Technology, Documentation, and People) provide a structured framework to assess your organization’s readiness and prioritize improvements ahead of a methane emissions assurance engagement.
