Independent Third-Party Verification, Assurance, Optimization, and Training
Supporting Reliable, Traceable, and Standards-Based ESG and Carbon Management Performance
—— Verify. Assure. Improve. ——
Your Trusted Partner on the Sustainability Journey
Through independent third-party verification and assurance, we help organizations turn sustainability commitments into measurable, credible, and actionable outcomes.
We believe sustainability should not be defined by promises alone, but by results that can be verified, assessed, and continuously improved.
Built upon our ESG Assurance Solution, iSDG combines Verified, Optimized, and iSDG Academy to support organizations in strengthening compliance, building evidence-based practices, and developing the capabilities needed for long-term sustainable success.
Third-Party Verification & Assurance
We conduct independent verification and assurance based on internationally recognized standards and evidence-based methodologies, ensuring that sustainability disclosures and performance outcomes are credible, traceable, and able to withstand external scrutiny.
Our services cover climate-related standards and frameworks, including ISO 14064-1, ISO 14067, ISO 14068-1, and TCFD. We also provide sustainability report assurance in accordance with the GRI Standards and support AA1000AS assurance engagements (Type 1 and Type 2 Moderate Assurance), helping organizations establish ESG disclosures with internationally recognized credibility.
Optimization & Improvement
Through our Verify & Optimize approach, we identify gaps, risks, and opportunities for improvement from an assurance perspective. Using a continuous cycle of Identify → Process → Implement → Analyze, we transform verification findings into actionable improvement pathways that enhance organizational performance, compliance readiness, and auditability.
Capability Building & Training
Through iSDG Academy, we help organizations develop internal sustainability and assurance competencies while establishing a shared professional language across teams. Our training programs are designed to make methodologies scalable, repeatable, and practical for implementation.
Course offerings include ISO 14064-1, ISO 14064-2, ISO 14067, ISO 14068-1, SBTi, EcoVadis, ESG, and other sustainability-related standards and frameworks.
Our Services
uilt on Assurance. Driven by Improvement. Empowered through Training.
At iSDG, our ESG Assurance Solution is built around three core pillars: Third-Party Verification & Assurance (Verified), Performance Optimization (Optimized), and Professional Training (iSDG Academy).
Through internationally recognized standards and evidence-based methodologies, we help organizations establish robust, traceable carbon and ESG management systems. Guided by our Verify & Optimize approach, we transform assurance findings into continuous improvement actions, enabling organizations to strengthen performance, enhance credibility, and sustain long-term progress.
Third-Party Verification & Assurance Services
We conduct reviews based on internationally recognized standards and evidence-based methodologies to ensure that corporate ESG performance is credible, traceable, and ready for external scrutiny.
Our professional scope includes:
Climate and Carbon Management: Verification services for ISO 14064-1 (organization-level GHG inventories), ISO 14067 (product carbon footprints), ISO 14068-1 (carbon neutrality), and TCFD-related climate disclosures.
Sustainability Report Assurance: Assurance services based on the GRI Standards and AA1000AS, supporting Type 1 and Type 2 Moderate Assurance to ensure that disclosed information aligns with the principles of inclusivity, materiality, and impact.
Optimization Solutions
Centered on our Verify & Optimize approach, we translate assurance insights into actionable improvement pathways. Through a continuous cycle of Identify → Process → Implement → Analyze, we help organizations identify gaps, reduce risks, and enhance performance.
Potential optimization areas include technical improvements, performance tracking, low-carbon materials, process enhancement, recycling and reuse, and transition planning toward carbon neutrality and net zero.
Corporate Training
Through iSDG Academy, we help organizations establish a shared internal language and practical capabilities, making sustainability methodologies repeatable, scalable, and easier to implement across teams.
Training topics may include ISO 14064-1 / 14064-2, ISO 14067, ISO 14068-1, SBTi, EcoVadis, ESG, and other related standards and frameworks. Learning pathways can also be tailored to different roles and responsibilities.
Turning Sustainability into Action, Evidence, and Results
At iSDG, we build our services on independent third-party verification and assurance, combined with our Verify & Optimize methodology. We help organizations transform sustainability requirements into actionable processes, traceable data, and verifiable outcomes.
From carbon management and sustainability disclosure frameworks to systematic performance improvement, we work alongside organizations to strengthen internal capabilities, reduce implementation barriers, and drive meaningful progress.
Our goal is to ensure that sustainability is not merely a compliance exercise, but a strategic driver of operational excellence, business resilience, and long-term performance.
