Sustainability reporting using GRI Standards 2021 - from materiality assessment to publication.
Why GRI
Why GRI?
The Global Reporting Initiative (GRI) provides the world's most widely used sustainability reporting standards. Over 10,000 organizations globally use GRI to disclose their environmental, social, and governance impacts in a structured, comparable format.
Investors, ESG rating agencies, and stakeholders recognize GRI as the benchmark for sustainability reporting. GRI reports demonstrate transparency, build trust with capital markets, and satisfy the disclosure expectations of customers, regulators, and civil society. For Indian companies navigating BRSR, CSRD, and CDP requirements, GRI provides a robust foundation that maps across multiple frameworks.
What We Do
Our GRI Service Scope
We provide end-to-end GRI reporting services - from initial materiality assessment through to published report and GRI database registration. Each engagement is tailored to your organization's size, sector, and reporting maturity.
Materiality Assessment
Impact materiality analysis aligned with GRI 3. Stakeholder mapping, topic identification, prioritization matrix, and documentation of material topics with their boundaries.
Stakeholder Engagement
Systematic identification of key stakeholder groups, structured consultation processes, feedback integration into reporting priorities, and documentation of engagement outcomes per GRI 2-29.
Data Collection & Analysis
Comprehensive data gathering across GRI 300 (Environmental), GRI 400 (Social), and GRI 200 (Economic/Governance) topic standards. We build structured data templates and validation checks.
GRI 305 Emissions Reporting
Scope 1, 2, and 3 emissions quantification using the GHG Protocol. Activity data collection, emission factor selection, calculation, and disclosure aligned with GRI 305-1 through 305-7.
Report Writing
Clear, balanced sustainability reports following GRI reporting principles - accuracy, balance, clarity, comparability, completeness, sustainability context, timeliness, and verifiability.
GRI Content Index
Full mapping of all reported disclosures to GRI Standards, with page references, omission explanations where applicable, and compliance with "in accordance" or "with reference" requirements.
External Assurance Coordination
Shortlisting qualified assurance providers, preparing data packages, managing the assurance process, and addressing findings. We ensure your report meets limited or reasonable assurance standards.
GRI Database Registration
Registration of your published report on the GRI Sustainability Disclosure Database for "in accordance" reports, increasing visibility to investors and ESG analysts globally.
Year-over-Year Tracking
Establishing baseline metrics, building comparability across reporting periods, trend analysis, and continuous improvement recommendations to strengthen each subsequent report cycle.
Standards
GRI Universal Standards (2021)
The 2021 revision of the GRI Universal Standards introduced significant changes that apply to all organizations reporting under GRI. Understanding these three foundational standards is essential for compliant reporting.
GRI 1: Foundation - Sets out the purpose and system of GRI Standards, defines key concepts such as impact materiality, and establishes the requirements for reporting "in accordance" with GRI. This is the starting point for any GRI report.
GRI 2: General Disclosures - Requires disclosure about the organization itself: governance structure, strategy, policies, stakeholder engagement practices, and reporting practices. These disclosures provide context for all topic-specific data.
GRI 3: Material Topics - Defines the process for determining material topics, including impact assessment and stakeholder input. Organizations must disclose how they identified material topics, their list of material topics, and how they manage each one.
Unified Reporting
GRI + BRSR: Unified Reporting
Many Indian companies need to report under both GRI Standards and BRSR. The good news: there is significant overlap. Many BRSR KPIs map directly to GRI disclosures - energy consumption, emissions, water withdrawal, waste generation, workforce diversity, and community engagement data serve both frameworks.
We help organizations build a single, integrated data collection system that feeds both GRI and BRSR reports. This eliminates duplicate effort, ensures consistency across disclosures, and reduces the overall cost and time of sustainability reporting. Read our complete guide to BRSR reporting or explore our BRSR reporting services.
For companies with EU exposure, GRI also maps well to TCFD climate disclosures and the EU CSRD requirements, making it an excellent foundation for a multi-framework reporting strategy.
Industries
Industries We Serve
GRI reporting applies across all sectors. We have experience preparing GRI reports for companies across India's key industries, with sector-specific knowledge of material topics, data sources, and reporting nuances.
End-to-end GRI reporting: materiality assessment, stakeholder engagement, data collection for GRI 300/400/200 series, report writing, GRI Content Index preparation, external assurance coordination, and GRI database registration. We support both first-time reporters and organizations looking to improve existing reports.
Does O₂log support both "in accordance" and "with reference" reporting?
Yes. We help companies determine the appropriate level and prepare accordingly. "In accordance" requires all applicable disclosures for each material topic; "with reference" allows selective reporting of specific GRI Standards. We recommend the level that best matches your reporting maturity and stakeholder expectations.
How does GRI relate to BRSR?
GRI and BRSR overlap significantly. Many BRSR KPIs map to GRI Standards - energy, emissions, water, waste, workforce data. Companies doing both can use a single data collection system. We help build unified reporting frameworks that satisfy both requirements efficiently. Learn more in our BRSR reporting guide.
How long does GRI report preparation take?
First-time reports typically take 12-16 weeks, with the materiality assessment phase taking the longest. Subsequent years are faster - usually 6-8 weeks - with established data systems, templates, and baseline metrics already in place.
