CLIMATE & SUSTAINABILITY STRATEGY
Double materiality is the EU's regulatory requirement — mandatory under CSRD and ESRS — that organizations assess sustainability topics from two perspectives simultaneously: how sustainability issues affect the business financially (financial materiality), and how the business affects people and the environment (impact materiality). The double materiality assessment is not a reporting exercise. It is the analytical decision that determines which sustainability topics an organization must disclose under ESRS, which topics anchor the GRI sustainability report, which risks and opportunities must be communicated under IFRS S2, and which areas of organizational activity require the most strategic attention.
Semtrio designs double materiality assessments that produce one documented, audit-ready output serving all three functions simultaneously — the CSRD/ESRS materiality determination, the GRI materiality matrix, and the risk and opportunity identification that IFRS S2 requires. One assessment. One stakeholder engagement process. Every framework anchored.
CSRD requires organizations to conduct and document a double materiality assessment as the basis for determining which ESRS topical standards apply to their sustainability statement. The assessment must be documented to a standard that satisfies external limited assurance — meaning it must record the methodology used, the stakeholders consulted, the impact and risk identification process, and the thresholds applied to determine materiality. An assessment conducted informally, or without the documentation depth that assurance providers require, is a CSRD compliance risk.
GRI's impact materiality concept — the identification of an organization's most significant impacts on people and the environment — is the impact dimension of double materiality. Organizations that conduct a rigorous double materiality assessment for CSRD are simultaneously completing the GRI materiality process. Semtrio designs the assessment methodology so that the impact materiality findings directly feed the GRI materiality matrix — no separate exercise required.
IFRS S2 requires organizations to identify material climate-related risks and opportunities — the financial materiality half of a double materiality assessment. An organization that has conducted a well-documented double materiality assessment has already performed the risk and opportunity identification exercise that IFRS S2 requires. Semtrio structures the financial materiality assessment to produce IFRS S2-compatible risk and opportunity outputs simultaneously with the ESRS materiality determination.
The most common failure in double materiality assessments is treating them as a reporting compliance exercise rather than an analytical decision tool. Organizations that conduct a materiality assessment primarily to check the CSRD box produce a defensible document but miss the strategic intelligence that a well-executed assessment generates: which sustainability topics create the greatest financial risk to the business, where in the value chain the organization's most significant impacts occur, which topics are most important to the investors and stakeholders whose relationships matter most commercially.
Semtrio designs double materiality assessments as a strategic decision-making process that produces a compliance output as a by-product. We structure the impact identification, financial risk assessment, and stakeholder engagement to generate insights that inform the sustainability strategy and capital allocation decisions — not just a matrix that satisfies a reporting obligation.
OUR PROCESS
A documented, auditable double materiality assessment — anchoring CSRD, GRI, IFRS S2, and sustainability strategy from one exercise.
The double materiality assessment is the mandatory first step of CSRD compliance — it determines which ESRS topical standards apply to the organization's sustainability statement. Semtrio designs the assessment and the ESRS disclosure architecture as a single integrated engagement, eliminating the gap between materiality determination and reporting execution.
Learn moreClimate is the most commonly material topic in double materiality assessments — from both impact and financial perspectives. A verified, methodology-aligned GHG inventory is the quantitative foundation for climate materiality determination and for the ESRS E1 disclosures that climate materiality activates.
Learn moreGRI's impact materiality requirement is satisfied by the impact dimension of a double materiality assessment — organizations that have conducted a Semtrio double materiality assessment can directly use the impact materiality findings as the GRI materiality matrix, without a separate materiality exercise.
Learn moreDouble materiality findings identify the ESG topics most significant to the business and its value chain — directly informing which EcoVadis assessment themes should be prioritized for improvement. Semtrio designs both engagements in coordination, using materiality findings to focus EcoVadis preparation on the topics with the greatest strategic and scoring impact.
Learn moreOne assessment designed to anchor every framework — and the strategic intelligence to make materiality useful beyond the compliance requirement.
Semtrio designs double materiality assessments at the intersection of ESRS methodology, GRI Standards, and IFRS S2 risk identification — producing a single output that simultaneously satisfies all three frameworks' materiality requirements. The framework mapping we produce is explicit: each material topic is linked to the ESRS topical standards it activates, the GRI topic-specific Standards it maps to, and the IFRS S2 risk and opportunity categories it corresponds to. Organizations that complete their double materiality assessment with Semtrio enter their ESRS reporting, GRI report production, and IFRS S2 disclosure with a complete, auditable materiality foundation — not a separately managed materiality process for each.
Beyond compliance, the quality of a double materiality assessment determines the quality of every strategic and reporting decision that follows it. The assessment identifies which topics drive the greatest financial risk and where the business has its most significant real-world impacts — intelligence that should be shaping capital allocation, operational improvement priorities, and investor communications. We design the assessment process to surface this intelligence as a primary output, not as an afterthought to the compliance documentation.

Frequently asked questions about double materiality assessment
Double materiality requires organizations to assess sustainability topics from two perspectives simultaneously. Financial materiality asks: how do sustainability issues affect the organization's financial performance, position, and prospects — what ESG risks and opportunities are material to investors? Impact materiality asks: how does the organization affect people and the environment through its operations and value chain — what are the organization's most significant impacts on society and the natural world? Single materiality — used by IFRS S2 and TCFD — covers only the financial materiality perspective. GRI covers only impact materiality. Double materiality — now mandatory under CSRD and its ESRS — requires both perspectives simultaneously, making it the most comprehensive materiality framework and the one that subsumes both IFRS S2 and GRI's individual requirements within a single assessment.
CSRD requires organizations to conduct a double materiality assessment as the basis for determining which ESRS topical standards are material to their sustainability statement. The assessment must identify the organization's actual and potential impacts, risks, and opportunities across its operations and value chain, apply documented thresholds to determine which are material from each perspective, and engage relevant stakeholders in the process. The assessment methodology, stakeholder engagement approach, impact and risk identification process, and materiality determination must all be documented in sufficient detail to satisfy external limited assurance. Material topics activate the corresponding ESRS topical standards: a material determination on climate change activates ESRS E1, on workers activates ESRS S1, and so on.
GRI's impact materiality requirement — identifying the organization's most significant impacts on people and the environment — is the impact dimension of double materiality. Organizations that conduct a rigorous double materiality assessment for CSRD are simultaneously completing the GRI materiality determination, producing the impact materiality matrix that GRI-aligned sustainability reports require. IFRS S2's requirement to identify material climate-related risks and opportunities is the financial materiality dimension of double materiality, focused specifically on climate. Organizations that conduct a complete double materiality assessment — covering financial materiality across all sustainability topics — are simultaneously generating the climate risk and opportunity identification that IFRS S2 requires. A well-designed double materiality assessment is therefore the single analytical exercise that anchors CSRD, GRI, and IFRS S2 simultaneously.
The double materiality assessment process involves four stages. First, impact identification — mapping the organization's actual and potential positive and negative impacts on people and the environment across operations and value chain. Second, financial risk and opportunity assessment — identifying how sustainability factors create risks to and opportunities for the organization's financial performance, strategy, and business model. Third, stakeholder engagement — consulting relevant stakeholder groups to gather perspectives on the identified impacts and financial risks and validate the materiality determination. Fourth, materiality determination and documentation — applying the agreed thresholds, producing the double materiality matrix, and documenting the complete assessment in assurance-ready format.
Semtrio conducts double materiality assessments in four phases. We begin with framework design and stakeholder mapping — establishing the assessment methodology, impact and risk identification scope, materiality thresholds, and stakeholder engagement plan. We conduct the impact identification and financial risk assessment — mapping impacts and ESG risks and opportunities across operations and value chain — and apply materiality thresholds to determine which topics are material from each perspective. We conduct the stakeholder engagement process and integrate findings into the materiality determination. We produce the final double materiality matrix with explicit mapping of each material topic to the relevant ESRS topical standards, GRI topic-specific Standards, and IFRS S2 risk categories — and deliver the assurance-ready documentation and strategic brief. The assessment is designed from the outset to serve CSRD, GRI, and IFRS S2 from one exercise, without requiring separate materiality processes for each framework.
