FAQ

ESG consulting and reporting with DEISO: frequently asked questions

What does DEISO do in ESG consulting and reporting?

DEISO is a Tokyo-based consulting firm that builds governance-ready ESG systems and reports. We select the applicable frameworks, assess materiality, structure ESG data and indicators, draft the report and prepare it for third-party assurance, with environmental and social metrics backed by DEISO's own LCA, S-LCA, GHG and EPD evidence.

Which ESG reporting frameworks does DEISO work with?

DEISO works with the GRI Standards, IFRS S1 and S2 from the ISSB, CSRD and the European Sustainability Reporting Standards (ESRS), Japan's SSBJ standards and CDP, and identifies which ones apply to your organisation.

What is a double materiality assessment?

A double materiality assessment looks at sustainability topics from two directions: impact materiality, meaning how your organisation affects people and the environment, and financial materiality, meaning how sustainability matters affect your organisation's financial position. ESRS requires it, and DEISO documents the results in an impacts, risks and opportunities register.

Can DEISO support CSRD and ESRS reporting?

Yes. The DEISO ESG Expert and Expert+ plans include an ESRS-aligned double materiality assessment, ESRS datapoint mapping and assurance readiness. DEISO prepares the report for assurance; assurance itself is carried out by an independent provider.

How do LCA, S-LCA and GHG data strengthen ESG reporting?

They give ESG claims quantified, system-based evidence. LCA and EPDs support product and environmental metrics, S-LCA supports social and supply-chain indicators, and GHG accounting supports climate disclosures, so the report rests on data that holds up under investor and assurance review.

Does an ESG plan include a GHG inventory?

ESG plans use your existing GHG data. A full Scope 1 to 3 GHG inventory is a separate DEISO GHG accounting plan, which can run alongside the ESG engagement.

Is third-party assurance included?

No. Third-party assurance fees are not covered by DEISO. Assurance is carried out by an independent assurance provider and paid by the client directly; DEISO prepares the report for assurance and coordinates the process.

How much does ESG consulting with DEISO cost?

DEISO ESG plans start from USD 9,500 for ESG Basic (readiness), USD 32,000 for ESG Pro (ESG report), USD 44,000 for ESG Expert (adds double materiality, datapoint mapping, assurance readiness, training and support) and USD 59,000 for ESG Expert+ (group programmes up to 3 entities), for one reporting year. Assurance fees are not included. See the plan comparison.

How long does an ESG engagement take?

ESG Basic typically takes 3 to 5 weeks, ESG Pro 2 to 4 months, ESG Expert 3 to 5 months and ESG Expert+ 4 to 6 months, counted from receipt of complete data and stakeholder availability.

How do I start an ESG engagement with DEISO?

Send a short description of your organisation, the frameworks or requirements you face, your reporting year and any existing ESG data to or through the quotation form. DEISO replies with scoping questions and a proposal covering frameworks, materiality approach, timeline and outputs.
