The Maturity-Based Pathways for Advanced Climate Reporting

Climate-related disclosure requirements are rapidly becoming the global baseline for corporate reporting.

The International Sustainability Standards Board (ISSB) issued IFRS S2 Climate-related Disclosures to establish a globally consistent framework for reporting climate-related risks and opportunities. The standard requires organisations to explain how climate matters affect governance, strategy, risk management, financial performance and long-term enterprise value.

Many stock exchanges and regulators have already adopted, or announced plans to adopt, IFRS S2-aligned reporting requirements. Companies should therefore begin strengthening their governance, internal processes, greenhouse gas accounting and climate risk management well before mandatory reporting takes effect.

At GreenCo ESG , we help organisations build practical and proportionate climate disclosure capabilities based on their current level of readiness. Whether your organisation is just beginning its climate reporting journey or preparing for full IFRS S2 compliance, we provide a structured roadmap that balances regulatory expectations with available resources.

IFRS S2 Is Becoming the Global Reporting Baseline

Today, IFRS S2 serves as the reference framework for climate-related reporting in many jurisdictions.

Different regulators may adopt the standard at different speeds or with local modifications, but the overall direction is clear — climate disclosures are becoming increasingly mandatory for listed companies and large organisations.

Examples include:

  • Hong Kong Stock Exchange (HKEX) Climate Requirements
  • Singapore Exchange (SGX) Climate Reporting Roadmap
  • Australian Sustainability Reporting Standards (ASRS)
  • IFRS Sustainability Disclosure Standards adopted in numerous jurisdictions

Rather than waiting until reporting becomes mandatory, organisations that prepare early are generally able to implement stronger governance processes, improve data quality and reduce future compliance costs.

Our IFRS S2 Advisory Framework

Every organisation starts from a different level of climate reporting maturity.

Some companies only require assistance in preparing their first climate disclosure, while others seek comprehensive support covering governance, climate strategy, scenario analysis, financial impacts and decarbonisation planning.

To accommodate different levels of readiness, GreenCo offers three advisory approaches.

Three Advisory Approaches

Baseline

  • Suitable for: Organisations beginning climate reporting

  • Consultant involvement: High

  • Company involvement: Review and approve

  • Recommended for: First-time reporters

Streamlined

  • Suitable for: Organisations enhancing existing climate disclosures

  • Consultant involvement: Shared

  • Company involvement: Active participation

  • Recommended for: Companies with existing ESG reporting

Comprehensive

  • Suitable for: Organisations pursuing full IFRS S2 alignment

  • Consultant involvement: Strategic partnership

  • Company involvement: Extensive management engagement

  • Recommended for: Companies seeking best practice disclosure

Instead of offering a one-size-fits-all solution, we assess each client’s existing governance arrangements, data availability, internal resources and reporting objectives before recommending the most appropriate approach.

Choosing the Right Approach

There is no single “correct” way to prepare for IFRS S2.

Some organisations prefer a consultant-led approach to minimise internal resource requirements, while others wish to build internal capabilities through greater management participation.

Our consultants first conduct a readiness assessment covering areas such as:

  • Existing ESG and climate disclosures
  • Corporate governance arrangements
  • Greenhouse gas data availability
  • Climate risk management processes
  • Internal reporting capability
  • Future regulatory obligations

Based on this assessment, we recommend the advisory approach that best matches your organisation’s reporting maturity, timeline and available resources.
