Pre-submission review

Independent review of your sustainability deliverables before they go out

Engage DEISO to independently assess your sustainability deliverables and strengthen them through structured, verification-ready technical assurance.

Senior LCA strategic advisory | ISO 14040/44 and EPD support

We provide senior-level strategic advisory for Life Cycle Assessment (LCA) programs aligned with ISO 14040 and ISO 14044, including structured methodological guidance for Environmental Product Declarations (EPDs). This engagement supports organisations in strengthening study architecture, system boundary definition, allocation logic, impact assessment method selection and documentation defensibility prior to formal verification or program operator submission.

Our advisory role is strictly independent and governance-focused. We evaluate methodological coherence, PCR alignment, modelling defensibility and disclosure positioning to reduce verification exposure and prevent costly rework.

By reinforcing analytical rigour at the structural level, we position your LCA and EPD deliverables as decision-grade sustainability assets suitable for procurement, investor scrutiny and regulatory environments.

Senior sustainability strategic advisory | ESG, climate, risk and environmental governance

We provide executive-level sustainability advisory to strengthen ESG architecture, climate governance frameworks, environmental risk integration and strategic alignment with global disclosure standards. This engagement is built for organisations seeking senior, independent insight before public reporting, investor engagement, regulatory submission or board-level approval.

Our advisory scope covers ESG structural maturity assessment, climate strategy alignment (Scope 1–3 governance), risk mapping, disclosure positioning and environmental data integration into enterprise decision systems. We evaluate governance coherence, methodological soundness and alignment with international frameworks to support defensible sustainability positioning.

By moving sustainability from a regulatory exercise to governance strategy, we help organisations reduce reputational exposure, strengthen investor confidence and build long-term environmental resilience embedded at the executive level.

Product Carbon Footprint (PCF) review

We conduct independent technical and pre-submission review of Product Carbon Footprint (PCF) studies prior to external verification, customer submission, regulatory disclosure or supply chain reporting. This engagement evaluates system boundaries, allocation logic, functional unit definition, emission factor selection, data representativeness and methodological alignment with ISO 14067 and GHG Protocol Product Standard requirements.

DEISO does not develop the PCF model under this service. We assess internally prepared or consultant-developed product carbon studies to identify structural inconsistencies, unsupported assumptions, calculation errors and documentation gaps before third-party scrutiny.

Our structured review reduces verification risk, strengthens supply chain credibility and buyer confidence, and supports defensible product-level climate disclosures. We position your PCF deliverables as governance-aligned, verification-ready climate intelligence assets.

LCA critical review (ISO 14040 / ISO 14044) — independent technical assessment

We conduct independent Life Cycle Assessment (LCA) critical reviews in accordance with ISO 14040 and ISO 14044 to evaluate methodological conformity, modelling integrity, data representativeness, allocation logic, impact assessment application and reporting transparency. This engagement is built for studies intended for public disclosure, comparative assertions, EPD publication, regulatory submission or high-level stakeholder scrutiny.

DEISO performs this service as an independent technical assessor and does not participate in the preparation or modelling of the study under review. Our structured assessment identifies methodological deviations, boundary inconsistencies, unsupported assumptions and reporting vulnerabilities prior to formal declaration or verification.

By confirming ISO-aligned conformity and analytical defensibility, we reduce reputational risk, build stakeholder confidence and strengthen the credibility of your LCA deliverables within procurement, ESG disclosure and regulatory environments.

Sustainability data governance and internal control review

We conduct independent reviews of sustainability data governance frameworks and internal control systems supporting ESG reporting, GHG inventories, LCA studies and environmental disclosures. This engagement evaluates data ownership structures, control procedures, calculation workflows, documentation traceability, system integration logic and cross-functional accountability mechanisms.

DEISO does not implement internal control systems under this service. We assess existing governance architecture to identify control weaknesses, data integrity risks, segregation-of-duties gaps, audit trail deficiencies and structural misalignment between sustainability data and enterprise reporting systems.

Our structured review strengthens assurance readiness and investor confidence, reduces regulatory exposure, and embeds sustainability into enterprise-grade governance architecture. We turn sustainability data from operational output into controlled, traceable, board-level intelligence.

AI strategic advisory for sustainability and research architecture

We provide executive-level AI strategic advisory tailored to sustainability systems, research architecture and environmental data governance. This engagement supports organisations seeking to integrate artificial intelligence into LCA modelling workflows, GHG accounting systems, ESG analytics, digital reporting frameworks and sustainability research infrastructure.

Our advisory scope evaluates data architecture readiness, model integration logic, automation potential, analytical reliability, governance controls and scalability alignment across enterprise sustainability systems. We assess both technical feasibility and strategic fit — so that AI deployment strengthens methodological integrity rather than introducing risk.

By aligning AI capability with sustainability governance, we help organisations move from static reporting structures to intelligent, automated, decision-support ecosystems. This service turns sustainability data into scalable, AI-supported strategic intelligence built for regulatory resilience and competitive advantage.

Independent ESG report review

We conduct independent, pre-submission technical reviews of ESG reports prior to public disclosure, investor engagement, regulatory filing or external assurance. This engagement evaluates the structural integrity, data consistency, boundary definition, materiality logic, governance alignment and methodological defensibility of your existing ESG documentation.

DEISO does not prepare ESG reports under this service. We strictly assess internally developed or consultant-prepared reports to identify unsupported claims, calculation inconsistencies, disclosure gaps, risk misalignment and governance weaknesses before third-party scrutiny.

Our structured review strengthens credibility, reduces reputational exposure, improves assurance readiness and builds investor confidence. By turning ESG reporting from narrative disclosure into defensible governance intelligence, we help organisations protect strategic positioning while improving transparency and accountability.

GHG emissions review (Scope 1–3)

We perform independent, pre-submission reviews of organisational greenhouse gas inventories covering Scope 1, Scope 2 and Scope 3 emissions. This engagement evaluates boundary definitions, activity data reliability, emission factor selection, calculation methodologies, consolidation approaches and documentation integrity in alignment with ISO 14064 and the GHG Protocol.

DEISO does not develop or calculate the emissions inventory under this service. We assess internally prepared or consultant-generated inventories to identify structural weaknesses, unsupported assumptions, data traceability gaps and methodological inconsistencies before third-party verification, regulatory submission or public disclosure.

Our structured review strengthens verification readiness, reduces assurance findings, builds investor confidence and improves climate governance defensibility. We turn carbon accounting from a reporting obligation into decision-grade climate intelligence.

EPD pre-submission review services

We conduct independent technical review of Environmental Product Declarations (EPDs) prior to submission to program operators or third-party verifiers. This engagement evaluates conformity with ISO 14025 requirements, applicable Product Category Rules (PCRs), underlying LCA methodological alignment, data consistency, impact calculation integrity and documentation completeness.

DEISO does not develop the EPD under this service. We assess internally prepared or consultant-developed EPD documentation to identify structural gaps, methodological inconsistencies, unsupported environmental claims and verification vulnerabilities before formal submission.

Our structured review strengthens approval readiness, reduces verification queries, protects market positioning and supports defensible environmental transparency. We position your EPD deliverables as credible, standards-aligned instruments suitable for green procurement, infrastructure tenders and international market access.

Scope 3 category-level pre-submission review | Categories 1–15

We conduct independent, category-level technical review of Scope 3 emissions inventories across Categories 1–15 to strengthen methodological defensibility prior to external verification, regulatory submission or supply chain disclosure. This engagement evaluates boundary definition, supplier data integrity, estimation methodologies, emission factor selection, spend-based versus activity-based approaches and calculation transparency in alignment with the GHG Protocol.

DEISO does not prepare or calculate Scope 3 emissions under this service. We assess internally developed or consultant-generated inventories to identify structural gaps, double-counting risk, category misclassification, unsupported assumptions and documentation weaknesses before third-party scrutiny.

Our structured review reduces assurance findings, strengthens buyer and investor confidence, and improves climate governance maturity. We turn complex Scope 3 inventories into defensible, review-ready climate intelligence aligned with enterprise risk management and decarbonisation strategy.

Industrial carbon and sustainability exposure diagnostic

We provide a structured diagnostic assessment built to identify carbon exposure, sustainability governance gaps and environmental data risks across enterprise systems. This engagement evaluates the structural integrity of carbon accounting frameworks, Scope 1–3 boundary logic, sustainability data governance architecture, supply chain emissions visibility and readiness for product-level environmental transparency such as PCF and EPD programs.

Unlike implementation engagements, this diagnostic focuses on mapping exposure, identifying systemic weaknesses and clarifying strategic priorities before organisations commit to large sustainability initiatives. By revealing methodological risks, governance gaps and disclosure vulnerabilities early, the diagnostic lets leadership teams make informed decisions about the most effective pathway for strengthening carbon management, sustainability governance and environmental reporting systems.

Industrial carbon readiness assurance program | Scope 1–3 and PCF governance

We run a structured Industrial Carbon Readiness Assurance Program built to evaluate enterprise preparedness across Scope 1–3 emissions governance, Product Carbon Footprint (PCF) methodology, internal controls and decarbonisation strategy alignment. This program integrates organisational-level carbon systems with product-level emissions transparency to assess structural maturity before regulatory enforcement, investor scrutiny or supply chain disclosure mandates.

DEISO does not develop inventories or PCF models under this program. We conduct a complete governance and methodological assessment of existing carbon architecture, identifying data reliability gaps, boundary inconsistencies, control weaknesses and strategic misalignment with international climate frameworks.

Our assurance framework strengthens regulatory positioning, reduces transition risk, builds investor confidence and prepares industrial organisations for evolving carbon regulation and procurement requirements. We position carbon governance as an enterprise-level strategic asset rather than a reporting obligation.

Supporting the Kingdom of Saudi Arabia Vision 2030 industrial transformation

DEISO provides strategic sustainability advisory and technical governance support aligned with the industrial transformation objectives of Saudi Arabia Vision 2030. This engagement supports industrial entities, infrastructure developers, energy operators and advanced manufacturing sectors in strengthening carbon governance, LCA readiness, ESG architecture and environmental compliance frameworks in line with evolving national and international requirements.

Our structured approach integrates Scope 1–3 carbon management, product-level environmental transparency, sustainability data governance and regulatory alignment within large-scale industrial systems. We support organisations preparing for international procurement, green financing access and investor-driven sustainability disclosure expectations.
