Sustainability reporting has traditionally been viewed as complex, largely because organisations have needed to navigate multiple frameworks to disclose their environmental, social, and governance impacts in ways that meet the needs of different audiences.
Investors seek clarity on financially material risks, regulators require compliance with evolving rules, and broader stakeholders expect transparency on social and environmental performance. This landscape has developed over decades, evolving from early environmental disclosures to today’s integrated reporting frameworks.
International Sustainability Standards Board
While reporting was once fragmented, it is now becoming more coherent with the emergence of the International Sustainability Standards Board (ISSB), which provides a global baseline for sustainability-related financial disclosures.
Today, many of the well-known frameworks continue to exist, but their principles and guidance have been consolidated and embedded within the ISSB standards. Rather than competing approaches, they now serve as complementary inputs that underpin a more unified reporting system.
Task Force on Climate-related Financial Disclosures
The Task Force on Climate-related Financial Disclosures (TCFD) focuses on how climate risks and opportunities affect an organisation’s financial performance. It covers governance, strategy, risk management, and metrics, helping investors understand potential climate-related impacts on enterprise value.
The TCFD framework has been absorbed by the ISSB and incorporated into a global accounting-style standard. Yet, the framework remains relevant as many companies require alignment with the TCFD structure – which is followed in the ISSB.
The Greenhouse Gas Protocol
The GHG Protocol provides the rules and categories for measuring and reporting greenhouse gas emissions, including Scope 1 (direct), Scope 2 (indirect energy), and Scope 3 (value chain) emissions. It is widely used as the technical foundation for climate reporting and feeds into other frameworks like CDP, TCFD, and SBTi.
Sustainability Accounting Standards Board (SASB)
SASB provides industry-specific standards that highlight financially material ESG topics. Its focus on decision-useful metrics makes it highly relevant for investors who want to evaluate sustainability performance in the context of financial risk.
Global Reporting Initiative (GRI)
GRI offers comprehensive guidance for reporting to a broad range of stakeholders, including employees, communities, and regulators. It covers environmental, social, and governance issues, providing a flexible and multi-stakeholder framework.
Science-Based Targets initiative (SBTi)
SBTi focuses on setting emissions reduction targets aligned with climate science. Organisations use its methodology to set Scope 1, 2, and 3 targets, and these targets feed into sustainability reports and disclosures, demonstrating credible climate action.
EU Taxonomy and Corporate Sustainability Reporting Directive (CSRD)
The EU Taxonomy defines which economic activities are environmentally sustainable, while CSRD mandates ESG reporting for large companies in Europe. Together, they provide a structured approach for mandatory, comparable, and auditable sustainability disclosures aligned with EU regulations.
Carbon Disclosure Project (CDP)
CDP collects self-reported environmental data from companies, cities, and regions, focusing on climate, water, and forests. Its platform enables transparent, comparable reporting and benchmarking, which is useful for investors, policymakers, and NGOs.
UN Global Compact (UNGC)
The UNGC provides principles-based guidance for organisations to align with global standards on human rights, labour, environment, and anti-corruption. Reporting through UNGC helps companies demonstrate ethical and socially responsible practices.
Integrated Reporting (IR Framework)
Integrated Reporting encourages organisations to combine financial and non-financial information in a single report, illustrating how sustainability factors influence long-term value creation. It introduces the concept of six capitals: financial, manufactured, intellectual, human, social, and natural.
ISO 14001
ISO 14001 is an international standard for environmental management systems. While not a reporting framework per se, compliance provides structured environmental data that supports sustainability disclosures and regulatory reporting.
ISO 26000
ISO 26000 offers guidance on social responsibility, helping organisations embed ethical and socially responsible practices. It informs reporting on human rights, labour practices, community engagement, and governance.
