Sustainability Reporting and Disclosure Services
Sustainability reporting is an essential practice for organisations seeking to communicate their environmental, social, and governance performance to stakeholders, regulators, and the broader investment community. At SESG, we deliver comprehensive sustainability reporting and disclosure services that transform complex ESG data into clear, credible, and compelling narratives aligned with global standards. Our team works alongside your organisation to build reporting frameworks that satisfy regulatory requirements while telling a meaningful story about your progress, challenges, and future ambitions.Why Sustainability Reporting Matters for Your Organisation
Effective sustainability reporting goes far beyond compliance. It strengthens stakeholder trust, attracts responsible investment, and provides leadership teams with a structured view of risks and opportunities across the value chain. With evolving regulations such as the International Sustainability Standards Board (ISSB) frameworks, AASB sustainability standards, and the European ESRS requirements, the expectations placed on corporate disclosure have never been higher. Organisations that invest in quality sustainability reporting position themselves ahead of regulatory change and gain a competitive advantage in capital markets. At SESG, our reporting specialists bring deep expertise in IFRS/ESRS, GRI, SASB, the UN Sustainable Development Goals, and a wide range of voluntary benchmarking standards. This breadth of knowledge allows us to guide your organisation through complex reporting landscapes and ensure every disclosure is accurate, material, and aligned with stakeholder expectations.Our Approach to Sustainability Reporting and Disclosure
We recognise that no two organisations share the same reporting priorities. That is why we take a tailored approach to every sustainability reporting engagement, beginning with a thorough assessment of your current disclosure practices, material topics, and stakeholder needs. From there, we collaborate closely with your team to structure reports that balance regulatory compliance with authentic communication. Our sustainability reporting services span the full disclosure lifecycle. We support organisations with framework selection and gap analysis, data collection and verification, narrative development, design and formatting, and final review processes. Whether you need a comprehensive annual sustainability report, a targeted climate disclosure aligned with TCFD or ISSB recommendations, or an investor-focused ESG performance summary, our team delivers reports that are thorough, transparent, and fit for purpose. We also help organisations develop integrated reporting strategies that connect financial and non-financial performance, providing a holistic view of value creation. This integrated approach to sustainability reporting ensures that disclosures resonate with diverse audiences, from institutional investors and rating agencies to employees and community stakeholders.Connecting Reporting with Compliance and Strategy
Sustainability reporting is most effective when it is embedded within your broader ESG strategy. Our consultants work with your leadership to align reporting outputs with strategic objectives, ensuring that every disclosure reinforces your organisation’s commitment to responsible business practices. We integrate sustainability reporting with impact measurement, materiality assessment, and stakeholder engagement to create a cohesive disclosure framework that evolves with your organisation. From regulatory compliance submissions to voluntary sustainability statements, our reporting and disclosure services are designed to reduce the burden on internal teams while elevating the quality and credibility of your public communications. We bring the technical expertise, industry knowledge, and editorial capability needed to produce sustainability reports that meet the highest standards of transparency and accountability.Key Benefits of Our Reporting & Disclosure Service

Proven Outcomes in Reporting & Disclosure
Case Study: Luxury Cruise Company – Sustainability Impact Report
We partnered with a global luxury cruise company to deliver their second Sustainability Impact Report, evolving and strengthening the foundations established in their first report. The 2025 edition was designed to meet the needs of investors, structured to align with the UN Sustainable Development Goals (SDGs), and began the transition towards the European Sustainability Reporting Standards (ESRS) to prepare for upcoming regulatory requirements.
Working closely with the company’s international teams across multiple regions, we extrapolated complex ESG data and translated it into a compelling, accessible, and visually engaging report. This evolution not only showcased progress against material sustainability issues but also provided investors with transparent, credible insights, reinforcing the company’s commitment to responsible growth and long-term value creation.
Case Study: Dual-Listed Mining Company – Sustainability Reporting Transition
We supported a Hong Kong and ASX-listed mining company in the evolution of their sustainability reporting approach. While they had traditionally reported against GRI disclosures, the company sought to align its reporting with a revised sustainability framework and begin transitioning toward a SASB- and AASB-aligned narrative to meet emerging investor and regulatory expectations.
Our role was to maintain the integrity of key voluntary sustainability disclosures while restructuring the report to present a compelling, standards-aligned story for external stakeholders. At the same time, we worked with the business to ensure the report served an internal purpose, highlighting case studies that showcased how teams across the organisation contribute to sustainability performance. This dual focus strengthened credibility with investors while motivating employees by connecting their work to broader sustainability outcomes.
Case Study: Power Station – AASB S2 Climate Disclosures Dry Run Report
We partnered with a power station operator to prepare an early dry run sustainability report against the AASB S2 disclosure standards. The objective was to assess current readiness, identify shortfalls, and provide clear insights into the organisation’s ability to meet upcoming regulatory requirements.
Through this process, we highlighted gaps across governance, risk management, and disclosure practices, while recognising existing strengths. The outcome was a practical roadmap for future compliance, giving the business confidence in its next steps and a clear plan to build capability ahead of mandatory reporting. This proactive approach positioned the company to respond effectively to regulatory change.
What reporting standard should I use?
When it comes to reporting standards, there are many to choose from and selecting the right ones for your organisation is important. Factors affecting selection can include compliance obligations such as reporting in line with the Australian Sustainability Reporting Standards (ASRS), investor expectations, resource availability and your company’s level of appetite for disclosing sustainability-related information. It may be that your organisation uses a mix of standards to satisfy varying requirements. A good place to start is to think about the key drivers for your organisation to develop a sustainability report.
What is the difference between the GRI and SASB reporting standards?
The two standards are similar in that they both provide a structured framework for disclosure of sustainability related issues. The key difference between the two is that GRI focuses on the broader societal and environmental impacts whereby SASB is more focused on financially material sustainability related information that is relevant to investors. GRI reporting is intended for a wider range of stakeholders whereas SASB is primarily focused on investors and providers of financial capital.
What are the benefits of using voluntary reporting standards?
Using voluntary reporting standards that go beyond your current obligation, provides structure and demonstrates an enhanced level of sustainability assurance, setting your company apart from its peers. Increased reporting reassures suppliers, investors, and customers with validated reports and transparency, strengthening trust and setting the standard.
