Sustainability Standards for ESG Reporting

As a corporate ESG and sustainability reporting expert, I require in-depth knowledge of Environmental, Social and Governance (ESG) voluntary and mandatory reporting frameworks and standards such as GRI, IFRS/ISSB, TCFD and the EU's CSRD. This knowledge helps me create effective disclosures and construct a sound strategic management narrative for a company's performance each year.

These ESG Standards and Frameworks are designed to help businesses transparently disclose and manage ESG governance, strategy, impacts, risks and opportunities, policies, performance, metrics and targets. ESG programs are typically structured around a set of material topics, and companies routinely update their stakeholders on any significant changes to their sustainability approach and give activity and performance updates on an annual basis.

Below, I've compiled some basic information on the most commonly used sustainability standards and frameworks in my field. I hope this list will be helpful for anyone who hopes to gain a stronger understanding of the reporting universe.

Recent updates To ESG Frameworks Standards

Recent consolidation and standards setting led by the International Sustainability Standards Board (ISSB) and the International Financial Reporting Standards (IFRS) has helped to merge some of the main branches of sustainability-linked financial reporting: SASB, IR and TCFD.

Their efforts have created an “international baseline of sustainability-related disclosures.” So far, they have launched S1 “General Disclosures” and S2 “Climate-related disclosures.”

However, GRI standards still remain important for multi-stakeholder reporting on environmental and social impacts, whereas ISSB created standards that are decision-useful for investors and other financial actors.

The EU has also developed its own set of mandatory sustainability reporting standards that go further than ISSB and IFRS in its requirements for social and human rights reporting (see CSRD below).

CSRD

The EU’s updated Corporate Sustainability Reporting Directive went into effect on January 5, 2023, requiring approximately 50,000 companies to report under the European Sustainability Reporting Standards (ESRS) for the 2023 fiscal year in 2024.

The EU standards (ESRS) are part of a broader sustainable finance ecosystem that includes the EU Taxonomy, Sustainable Finance Roadmap, and the European Green Deal.

CSRD snapshot:

• Replaces the EU NFRD (Non-financial reporting disclosure)

• Effective for the first time for the reporting year 2024 with the first compliant reports published in 2025

• 50,000+ businesses to disclose under CSRD according to a phase-in schedule. Includes EU-based subsidiaries of in-scope companies headquartered outside of the EU. Includes reporting on the entire value chain of in-scope companies, including suppliers located outside of the EU.

• Reporting period aligns with annual financial reporting period.

• Reporting should be published in the management report section of the financial report in XBRL format.

• Limited assurance is required for reported information.

• CSRD aims for reporting interoperability with GRI, TCFD, IFRS/ISSB and other major reporting frameworks.

CSRD applies a “double materiality” lens to reporting. All organizations required to report under CSRD should prepare a double materiality assessment that considers outward and inward impacts on organizations.

• Outward impacts: These include the positive and negative, actual and potential impacts on people and the environment in the short-, medium- and long-term.

• Inward impacts: These include the financial risks and opportunities associated with material topics across the value chain in the short-, medium-, and long-term.

Companies are required to report on general disclosuers and material topic disclosures either covered by one of the ESRSs for the E, S, and G categories or other company-defined metrics. The EU's EFRAG (the standard setting authority) is in the process of developing sector standards in addition to its topic standards.

CSRD includes "cross-cutting standards” which are standard reporting requirements for each material topic including governance (GOV), strategy (SBM), impacts, risks and opportunities (IRO), policies and actions (PA), and metrics and targets (MT). In addition to these disclosures, companies should report on specific metrics and recommendations for reporting outlined within the relevant material topic standards.

All companies should report on ESRS E1 Climate Change, unless they can explain a strong reason for excluding this disclosure. ESRS E1 includes Scope 3 emissions and generally follows the GHG Protocol, though it requires reporting with an operational boundary, without the option to choose a financial or equity share boundary.

GHG Protocol

The GHG Protocol Corporate (Scope 1 and 2) Standard and Value Chain (Scope 3) Standard is a framework referenced in most other standards and frameworks for reporting on greenhouse gas (GHG) emissions. It provide recommendations for creating a GHG inventory and mapping emissions across organizational structures.

Under the GHG Protocol, companies can determine whether they apply operational, financial or equity share boundaries, measure location-based or market-based Scope 2 emissions, and other issues that aid flexibility.

GHG Protocol snapshot:

• Originally established in 1998 with subsequent initial publications of its Corporate Standard (2004) and Value Chain Standard (2009), which are regularly updated.

• GHG Protocol is referenced within TCFD (metrics and targets), GRI (material topic on GHG emissions), CDP and other major standards and frameworks.

• Recommends reporting all major GHG emissions by type and converting these into their CO2 equivalents

• Organizations define and report their GHG emissions as Scope 1, 2 and 3 emissions:

  • Scope 1 emissions: Direct operational emissions from fuel burning in vehicle fleets, furnaces or other equipment, emissions from industrial processes and fugitive emissions (such as refrigerants.

  • Scope 2 emissions: Indirect operational emissions from purchased electricity, heating or other energy or water resources, usually from utilities.

  • Scope 3 emissions: Indirect value chain emissions from business relationships across the upstream, downstream, transportation, product, investment, leased asset, and employee emissions (across a total of 15 common categories). These emissions require data collection from parties external to an organization and generally use estimates using emissions factors. For most organizations, the majority of their emissions are reflected in their Scope 3 emissions.

GRI*

*Learn about my GRI certification here.

The Global Reporting Initiative (GRI) is a set of cross-sector sustainability standards for environmental, social and governance issues developed by multi-stakeholder input through the Global Sustainability Standards Board. GRI is one of the longest standing and most widely adopted set of ESG reporting standards.

GRI snapshot:

• Founded in 1997. GRI has provided global sustainability reporting standards since 2016.

• 10,000+ companies report using GRI standards in over 100 countries.

• 73% of the world’s 250 largest companies report using GRI standards. 

• There is no reporting deadline set by GRI. Companies report according to their own stated reporting period.

• Where there are reasons for omission, it is helpful to report plans to develop a specific process or management system for a given disclosure.

• GRI provides advice on alignment with SDGs, SASB and TCFD among other standards.

• GRI emphasizes the Rio precautionary principle suggesting lack of scientific certainty should not prevent mitigation of serious or irreversible environmental impacts.

• GRI also emphasizes human rights practices in alignment with the Universal Declaration of Human Rights.

The GRI standards are outward facing, meaning they focus on the impacts businesses have on society. Other frameworks that require reporting on the risks posed by climate or other ESG issues on businesses.

GRI regularly updates its standards with the most recent 2021 update effective as of January 1, 2023. The 2021 updated standards emphasize four key areas: impact, materiality, due diligence and stakeholder engagement.

Companies may either report as members of GRI by reporting “in accordance” with the standards, and providing responses or reasons for omission to all required disclosures, or they may report “with reference” to the standards, a more flexible option for businesses gearing up to report under GRI. All disclosures are generally contained in a GRI content index in the appendix of an ESG report.

The structure of the standards is as follows:

• GRI 1, 2 and 3 are the universal standards which all companies reporting under GRI should disclose. These standards replace GRI 101, 102 and 103 from the 2016 standards.

• GRI 1 includes the nine foundational principles of reporting and best practices. It is basically the instruction manual for effective reporting under GRI. It contains the 8 principles organizations are expected to apply across their reporting: accuracy, balance, clarity, timeliness, verifiability, completeness, sustainability context, and comparability

• GRI 2 contains general disclosures that all businesses must report on. It includes general information about the organization and its reporting practices and ESG data relevant to all sectors. The main sections within GRI 2 are organization and reporting practices; activities and workers; governance; strategy, policies and practices; and stakeholder engagement.

• GRI 3 contains 3 disclosures on the development of the material topics considered by an organization. Organizations are expected to disclose their process to consider their actual and potential positive and negative impacts for environmental, social and governance issues. They should also disclose their list of material topics and how they manage their impacts.

• GRI Sector Standards are currently in development. GRI expects to release a total of 40 sector standards, starting with the highest priority sectors. So far just 3 have been made public: Oil and Gas (GRI 11), Coal (GRI 12) and Agriculture, Aquaculture and Fishing (GRI 13). Organizations are required to report using the sector standards for their industry, if sector standards are available.

• GRI Material Topic Standards are not new for 2021. They are a list of disclosures for material topics organizations have selected in their process of determining what issues are material to their organization. Organizations are required to report on the material topic standards that they have chosen in their list of material topics.

IFRS & ISSB

With the creation of the International Sustainability Standards Board (ISSB) at COP26 on November 3, 2021, the International Financial Reporting Standards (IFRS) announced the launch of a series of consolidation and standards setting efforts.

Timeline of changes:

• In 2021, the International Integrated Reporting Council (IIRC) and the Sustainability Accounting Standards Board (SASB) consolidated into the Value Reporting Foundation (VRF) in 2021.

• In June 2022, further consolidation of the Carbon Disclosure Standards Board (CDSB) and VRF into the International Financial Reporting Standards (IFRS) finalized.

• In July 2023, ISSB released its S1 General Disclosures Standards and its S2 Climate-related disclosures, while IFRS took over the responsibility for TCFD monitoring.

The result is a streamlined global set of standards aimed at supporting the transition of financial flows towards sustainable business and activities.

IIRC

The Integrated Reporting Framework integrates financial and non-financial reporting into the same strategic review and planning cycle, while drawing connections across financial and sustainability performance. 

In 2021, SASB and the International Integrated Reporting Council (IIRC) merged to form the Value Reporting Foundation, to combine approaches. 

SASB

Even though the Sustainability Accounting Standards Board (SASB) has been consolidated with IIRC into VRF and IFRS, it helps to understand how the standards developed. The standards were established in 2011 to improve the cross-comparability of sustainability metrics, especially for investors interested in simplifying ESG comparisons with clear KPIs.

SASB Snapshot:

• Created in 2011.

• Recently consolidated into VRF and IFRS.

• Uses a sector-based standards approach with clear, simple KPIs.

The SASB Framework covers 5 main areas and 26 key issues:

• Social Capital - Human rights and community relations, customer privacy, data security, access and affordability, product quality and safety, customer welfare, selling practice and product labelling 

• Human Capital - Labor practices, employee health and safety, employee engagement, diversity and inclusion

• Governance - Business ethics, competitive behavior, management of the legal and regulatory environment, critical incident risk management, systemic risk management

• Business Model - Product design and lifecycle management, business model resilience, supply chain management, materials sourcing and efficiency, physical impacts of climate change

• Environment - GHG emissions, air quality, energy management, water and wastewater management, waste and hazardous materials management, ecological impacts

SASB standards provide details on key material sustainability issues across 77 industries. 

TCFD*

*Learn about my Climate Risk certification here.

The Task Force on Climate Related Financial Disclosures (TCFD) is a set of recommended disclosures created by the Financial Stability Board (FSB) in 2015. The aim of TCFD is to provide governments, investors and financial institutions with data on climate-related financial risks and opportunities and the management of these risks.

Many current reporting regulations are based at least in part on the TCFD’s framework, as it is considered the most effective means for identifying potential systemic risks within financial systems.

TCFD snapshot:

• Created in 2015.

• 4,000+ reporting organizations and financial institutions.

• Report due within four months after the entity’s financial year-end.

• Annual reporting recommended.

• Many other standards and frameworks aim to align with TCFD: CDP, GRI, etc.

• TCFD is a set of forward-looking recommendations. Effective reporting often requires the support of data analytics and machine learning software that draws on climate science, geographic location and socio-economic data sets.

These financial risks fall into two categories: physical risks (and/or opportunities) from direct acute or chronic climate hazards and transition risks (and/or opportunities) from climate-related changes to policy and regulations, litigation trends, technology, consumer demand and reputation.

TCFD recommends disclosures on four key areas:

• Governance 

• Ensuring board oversight of climate risks. 

• Describe management’s role and process for conducting climate risk assessments. 

• Strategy 

• Assessing climate related physical and transition risks and opportunities for assets and portfolios and reporting on the impacts of these risks and opportunities on strategy and financial planning. 

• Conducting scenario analysis to explore and quantify the financial impacts (risks and opportunities) of climate change to assess business resilience per a range of scenarios including 2C warming. 

• Risk Management 

• Describe the risk management processes for assessing and reporting climate risks and opportunities. 

• Describe how climate risk assessment is integrated into broader risk management processes. 

• Metrics and targets 

• Reporting GHG emissions for Scope 1, 2, and 3 (recommended). 

• Describe the metrics used for reporting climate risk. 

• Describe the targets in place for managing climate risk and report performance against targets.

TCFD has a unique emphasis on comparing forward-looking short-, medium- and long-term climate risks. This acknowledges an important fact about climate risks: business activities today can significantly impact future climate hazards, by either growing or diminishing the risk curve.

TCFD also recommends scenario analysis of at least two pathways, given that climate risks vary significantly between a lower warming scenario versus a higher warming scenario. Businesses are expected to disclose their strategy for climate risks and opportunities in consideration of these varying scenarios.

TCFD reporting captures the “inward facing” risks of climate change on business. For example, physical risks are determined using the hazard, vulnerability and risk (HVR) framework that combines external hazards with vulnerabilities based on asset structures, insurance coverage, or other metrics to quantify the resulting financial risk from issues like flooding, temperature increase, wildfires, the increasing probability of damage from storms, etc.

For individual businesses, asset materials and location data can be used to assess physical risk, while carbon pricing can generally be used as a proxy to quantify transition risk. For larger financial institutions and banks, other means of arriving at estimates across investment portfolios are used to simplify the risk quantification process.

UN SDGs

The United Nation Sustainable Development Goals are a set of 17 goals with a total of 169 associated targets to achieve by the year 2030. They are part of the UN’s 2030 Agenda for Sustainable Development, which was launched in 2015.

SDGs snapshot:

• Created in 2015.

• 83% of global companies have showed support for the UN SDGs

• While the SDGs do not directly align with other standards, companies often disclose when their activities align with SDGs in their ESG reports.

• SDGs are broad-reaching goals intended to drive action with specific targets.

Sustainable development, by definition, is balancing the needs of future generations with those of today. This means society must avoid depleting resources beyond their ability to regenerate, or harming groups of people to the extent that they may struggle to access basic needs or enjoy human rights.

Sustainability has been implemented in multi-national frameworks through goals and target-setting, rather than strict rules and policies. The UN SDGs are an example of this.

The SDGs engage the private sector to contribute to making improvements on globally impacting issues ranging environmental, social and economic (ESG) topics. SDGs are also used by the public sector and non-profits to drive action towards societal improvements.

Businesses reporting their ESG activities often disclose the alignment of these activities with the UN SDGs, which may also influence organizations’ policies and initiatives.

UN Global Compact (UNGC)

More information coming soon.

Key facts:

• Launched in 2000, it is a UN pact encouraging businesses to adopt sustainable practices and report on their activities. 

• It has 13,000 participants and representatives from 170 countries. 

• The cross-sector framework covers 10 principles on  4 key areas:

• Human rights

• Labor

• Environment

• Anti-corruption 

CDP

Originally the “Carbon Disclosure Project,” CDP boasts the world’s largest database of environmental data on the private sector with information businesses voluntarily report. The database is used by stakeholders interested in business activities such as banks, investors and customers.

CDP snapshot:

• Founded in 2000.

• 13,000+ businesses disclose through CDP.

• Questionnaire responses are due on July 26 each year.

• Answering questions inadequately is better than leaving them blank in the eyes of CDP.

• CDP’s questionnaire aligns with TCFD.

• CDP includes climate, forest risks and water security questionnaires.

Businesses responding to the questionnaire often do so at the request of their investors or partners, but they may also do so voluntarily without receiving a request. By reporting data to CDP, they may improve their reputation and better assess environmental risks and track and benchmark their progress.

Its questionnaires cover three main areas: climate, forests and water security. The questionnaire includes sector specific questions and respondents are only scored on their primary sector. CDP scores each member who submits a questionnaire a letter rating and publishes an annual A-List of top-performing entities. It regularly reviews and updates the requirements for receiving a high score.
