What is GHG Protocol?

What is GHG Protocol and How Can You Ensure Compliance?

The Greenhouse Gas Protocol, or GHG Protocol, is the leading international framework for measuring and managing greenhouse gas (GHG) emissions.

It was developed in partnership between the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD). The GHG Protocol was first introduced in the late 1990s to establish a common language and methodology for businesses, governments, and other entities to assess and report their emissions accurately and consistently.

In this guide we will dive deeper into the topic of the GHG Protocol and explain its core standards, the different scopes of emissions it covers, and the ways different businesses can utilize it to achieve sustainability goals.

Understanding the GHG Protocol

The GHG Protocol provides the foundational principles and guidelines for entities aiming to monitor and manage their greenhouse gas emissions. Today, it supports not only voluntary carbon accounting but also aligns with mandatory reporting initiatives globally. It’s used across the globe by companies, cities, and governments to measure their emissions, identify reduction opportunities, and implement meaningful climate action.

Who Uses the GHG Protocol?

The GHG Protocol applies to a diverse array of stakeholders, including businesses of all sizes, government bodies, non-governmental organizations (NGOs), cities, and investors. 

  1. Businesses: Companies, including 92% of Fortune 500 firms, use the GHG Protocol to calculate and manage their emissions. Its standards serve as the basis for various corporate sustainability initiatives.
  2. Governments: National, regional, and local government entities use the protocol to align with international agreements, such as the Paris Agreement. The GHG Protocol is also used to design effective climate policies.
  3. Cities and Municipalities: Urban centers apply the GHG Protocol to track emissions from sources like transportation, public infrastructure, and energy use.
  4. Investors: Investors are also increasingly turning to GHG data to evaluate the climate risk exposure of businesses and assess their alignment with long-term climate commitments.

NGOs and Research Institutions: Non-profits and research bodies also use the protocol to gather data and benchmark environmental goals in the fight against climate change.

Breaking Down Emissions: Scope 1, 2, and 3

One of the GHG Protocol’s major contributions is its categorization of emissions into these three scopes:

  • Scope 1 (Direct Emissions): Emissions from sources owned or controlled by the organization, such as company vehicles or manufacturing facilities.
  • Scope 2 (Indirect Emissions from Purchased Energy): Emissions generated by the production of electricity, heat, or steam that the company purchases and uses.
  • Scope 3 (Indirect Value Chain Emissions): The broadest and most challenging category to measure, Scope 3 includes emissions up and down the value chain, from supplier activities and product distribution to employee travel and customer product use.

The Importance of Scope 3 Emissions

Scope 3 emissions reveal an organization’s broader environmental impact by considering emissions beyond direct control. Therefore, tracking these emissions enables companies to influence sustainability within their entire ecosystem.

For example, engaging suppliers in emissions reduction or enhancing product design to lower environmental impact throughout the product’s lifecycle can reduce Scope 3 emissions significantly. Addressing Scope 3 is a growing priority as it directly aligns with comprehensive climate goals and often represents a significant portion of total emissions.

Core Standards of the GHG Protocol

To meet the diverse needs of various sectors the protocol includes several standards.

  1. Corporate Standard: The foundation of the GHG Protocol, this standard guides businesses in calculating emissions from both direct (Scope 1) and indirect (Scope 2 and Scope 3) sources, providing a complete carbon footprint of their operations.
  2. Corporate Value Chain (Scope 3) Standard: Focused on emissions that fall outside a company’s direct operations, this standard helps organizations assess emissions across the entire value chain—from suppliers to product end-of-life.
  3. Product Standard: This standard is designed to help companies assess emissions tied to a product’s entire life cycle, from sourcing and manufacturing to disposal.

GHG Protocol for Cities: This framework is tailored for urban emissions, enabling cities to measure and manage emissions from local sources, infrastructure, and public services.

Regulatory Compliance

Governments worldwide are implementing stricter regulations on climate impact reporting. Businesses that start early with carbon accounting can better prepare for these legal requirements and avoid penalties. Accurate carbon data also helps organizations stay ahead of future regulatory changes.

Business Opportunities

Carbon accounting is not just about compliance and sustainability. Companies that track and reduce their emissions can gain competitive advantages, minimize operational inefficiencies, and strengthen brand loyalty by demonstrating environmental responsibility.

Risk Reduction

Accurate carbon accounting helps businesses avoid the risk of greenwashing—making misleading claims about their environmental impact. Many companies unintentionally overestimate their sustainability efforts and carbon accounting provides a clear and accurate measure to mitigate this risk.

What Does Carbon Accounting Mean in Today’s Business Environment?

In today’s world, carbon accounting represents a strategic approach to understanding and reducing carbon footprints, ensuring a sustainable future for everyone. 

Companies across industries use carbon accounting to achieve net-zero emissions, which refers to balancing the amount of greenhouse gasses emitted with an equivalent amount of carbon removal or offset.

How Does Carbon Accounting Work?

Furthermore, carbon accounting revolves around two core elements: data collection and data processing. To accurately calculate emissions, you need two types of data:

  • Business data: Information about business activities, such as the amount of fuel consumed or goods purchased.
  • Emissions factors: The amount of GHG emissions associated with each unit of business activity.

Once the necessary data is collected, one can estimate their carbon footprint using one of two primary methods: spend-based or activity-based.

Spend-Based Method

This approach calculates emissions by multiplying the financial value of a purchased good or service by an emissions factor. It’s a quick way to estimate carbon emissions but tends to be less precise as it relies on industry averages.

Activity-Based Method

This method, on the other hand, is more specific and accurate, using actual data on the quantity of materials, fuel, or other resources used. Emission factors from scientific studies are then applied to calculate emissions.

Hybrid Method

A combination of the two, the hybrid method is recommended by the Greenhouse Gas Protocol, the most widely used standard for carbon accounting. It allows businesses to use activity-based data where possible and supplement it with spend-based estimates where data is lacking.

Key Outputs of Carbon Accounting

The result of carbon accounting is an estimate of a business’s total carbon footprint, typically broken down into three “scopes” based on the Greenhouse Gas Protocol:

  • Scope 1: Direct emissions from owned or controlled sources (e.g., company vehicles, manufacturing processes).
  • Scope 2: Indirect emissions from purchased energy (e.g., electricity).
  • Scope 3: All other indirect emissions, such as those generated by suppliers or the use of sold products (often referred to as value chain emissions).

Aligning with these standards ensures that your business is compliant with regulations and you can publicly share your sustainability efforts with confidence.

For an in-depth breakdown of these standards, including how to apply them to your business, explore our Guide to Carbon Accounting Standards and Global Frameworks.

Carbon Accounting Software: Automating the Process

Given the complexity of collecting and analyzing emissions data, many companies are turning to carbon accounting softwares to streamline the process. These kinds of softwares automate data gathering from various sources, making it easier to produce accurate carbon footprints and meet reporting requirements. 

It’s especially beneficial for businesses with extensive supply chains, where manual data collection would be time-consuming and prone to errors.

Using a carbon accounting software does not only help to save time, but it also provides more precise insights into emissions hotspots, helping companies target the most impactful areas for reduction.

Carbon Accounting for Enterprises: Tackling the Value Chain

For large companies, especially those with thousands of suppliers, carbon accounting is crucial for identifying emissions within the value chain. 

On average, value chain emissions (Scope 3) account for 92% of a business’s carbon footprint. Hence, these emissions don’t come directly from the company but from the smaller businesses that supply goods and services.

Enterprises can start by using a spend-based approach to estimate value chain emissions. From there, they can refine their data by gathering activity-based information from their most significant suppliers. This targeted approach ensures that carbon reduction efforts focus on the most impactful areas.

Carbon Accounting Management: Building Expertise in a Growing Field

As carbon accounting becomes a core business function, professionals in sustainability, finance, and operations are increasingly seeking to enhance their expertise in the field.

Through carbon accounting courses or advisory services they are offered training on methodologies, data collection, and reporting standards, equipping individuals with the knowledge to lead their organization’s sustainability initiatives. These courses are an excellent way to stay ahead in a rapidly evolving area of business.

Why Carbon Accounting Standards Matter

Carbon accounting standards are more than just compliance tools—they are strategic enablers for organizations looking to be leaders within sustainability. By adopting these frameworks, businesses can:

  • Enhance transparency through clear and verifiable reporting of emissions data.
  • Benchmark performance by comparing their carbon footprint with industry peers.
  • Drive informed action by identifying reduction opportunities and aligning with science-based targets.

The Key Carbon Accounting Standards

1. Greenhouse Gas Protocol (GHGP)

The GHG Protocol is the most widely adopted framework for measuring and managing emissions globally. Jointly developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), it forms the foundation of most other frameworks as well.

Its structure categorizes emissions into three scopes, to give us a comprehensive understanding of different types of carbon footprint. 

  • Scope 1 (Direct Emissions): These emissions stem from sources directly owned or controlled by an organization (e.g., fuel combustion in company-owned facilities).
  • Scope 2 (Indirect Energy Emissions): These result from the electricity, heating, or cooling purchased and used by the company. Tracking Scope 2 is crucial for organizations pursuing renewable energy adoption.

Scope 3 (Value Chain Emissions): Often the largest source of emissions, Scope 3 includes indirect emissions across the value chain, such as supplier activities, waste, and employee travel. While challenging to measure, they are critical for developing a holistic carbon strategy.

inforgraphic showing the three scopes of emissions in carbon accounting: Scope 1 (Direct Emissions), Scope 2 (Indirect Energy Emissions), and Scope 3 (Value Chain Emissions), with examples for each.

The GHG Protocol is foundational for frameworks like ISO 14064, PCAF, and regulatory mandates such as the CSRD. For a detailed exploration, refer to our Guide to the GHG Protocol.

2. ISO Standards for Carbon Management and Neutrality

ISO 14064

ISO 14064, developed by the International Organization for Standardization (ISO), complements the GHG Protocol by offering detailed methodologies for GHG quantification, reporting, and verification.

It is divided into three parts: Part 1 focuses on organization-level GHG inventories, addressing Scopes 1 and 2; Part 2 is tailored for project-level emissions, such as renewable energy installations or carbon capture initiatives; and Part 3 ensures independent validation and verification of emissions inventories or reductions.
ISO 14064 is ideal for organizations already working within ISO management system frameworks, providing a seamless path to integrating environmental goals.

ISO 14068-1:2023

Effective January 2025, ISO 14068-1:2023 will replace PAS 2060 as the global standard for carbon neutrality verification. Introduced at COP28, ISO 14068-1 builds on the foundation of standards like ISO 14064, offering a rigorous framework for organizations to measure, reduce, and offset their emissions systematically. 

Key features include a strong focus on emission reduction, prioritizing meaningful reductions over offsets to align with long-term climate goals, and independent verification to ensure the credibility of neutrality claims. By adopting ISO 14068-1, organizations can credibly pursue carbon neutrality while adhering to the highest standards of accountability.

3. Partnership for Carbon Accounting Financials (PCAF)

PCAF addresses the growing demand for carbon accounting in the financial sector by focusing on financed emissions, or emissions generated by an institution’s investments and lending activities.

They have tailored approaches for different types of assets, such as corporate loans, mortgages, and private equity. This means that each financial sector can measure its carbon impact in a way that fits its specific activities, making the process more accurate and relevant.

In addition, PCAF aligns with the Greenhouse Gas (GHG) Protocol’s Scope 3, particularly Category 15, which focuses on emissions from investments. This helps financial institutions assess the carbon footprint of their investments, making it easier to align their strategies with science-based climate targets and assess climate-related risks.

4. IFRS Sustainability Disclosure Standards (S1 and S2)

The IFRS Sustainability Disclosure Standards are becoming the global baseline for climate-related financial disclosures. IFRS S2, in particular, focuses on climate risks and opportunities, requiring organizations to disclose material information about emissions, climate resilience, and governance processes.

Key elements include

  • Governance: Emphasizes board-level oversight of climate-related risks and opportunities.
  • Scenario Analysis: Guides modeling of climate scenarios and their potential impact on business performance.
  • Metrics and Targets: Promotes comprehensive reporting of emissions across all scopes.

IFRS S2 is increasingly viewed as essential for global reporting and compliance, particularly in jurisdictions like the EU.

Key Features of the CSRD

The Corporate Sustainability Reporting Directive introduces several key features designed to enhance corporate accountability and transparency:

Enhanced Transparency

Under the CSRD, companies are required to standardize the reporting of their sustainability efforts. This change enables stakeholders to make informed comparisons across industries. Take, for example, a company that has long reported its climate impacts in a transparent manner. With the CSRD, other companies will need to follow, ensuring consistency and reducing the prevalence of vague or misleading claims.

Double Materiality

The principle of double materiality expands corporate reporting beyond financial impacts. Companies must report both how ESG factors affect their financial health and how their operations impact society and the environment. A company reporting on carbon emissions not only discusses the risks it faces due to climate change but also how its emissions contribute to global warming.

Auditing Requirements

One of the significant changes brought by the CSRD is the requirement for third-party auditing of sustainability reports. This ensures that the disclosed information is accurate, making the reported data trustworthy. With sustainability becoming a competitive differentiator, the inclusion of independent audits prevents businesses from overstating their ESG achievements.

Integrating Standards with Other Frameworks

CSRD Reporting

The Corporate Sustainability Reporting Directive (CSRD) mandates detailed disclosures on sustainability, including emissions data. Organizations can simplify compliance by adopting standards like the GHG Protocol or ISO 14064, which provide the rigorous methodologies required for these disclosures. Learn more in our CSRD Reporting Guide.

Aligning Multiple Standards

What is CSRD? Overview of the Corporate Sustainability Reporting Directive

What is CSRD? Overview of the Corporate Sustainability Reporting Directive

The Corporate Sustainability Reporting Directive (CSRD) was introduced by the European Commission late in 2022, and is a groundbreaking piece of legislation that reshapes how companies across Europe disclose their environmental, social, and governance (ESG) performance.

stable of wooden bricks with sustainability illustrations

This directive is a significant evolution from the previous Non-Financial Reporting Directive (NFRD), expanding both the scope of companies required to report and the depth of information that is required. In essence, CSRD is placing sustainability at the heart of corporate accountability, not only influencing EU-based businesses but also international companies with significant operations within the EU.

In this guide, we’ll dive deeper into what CSRD is, its objectives, reporting requirements, and what businesses need to do to comply.

What Does CSRD Stand For?

CSRD stands for the Corporate Sustainability Reporting Directive, a legislative initiative aimed at harmonizing and enhancing sustainability reporting standards across the European Union. Additionally, the CSRD represents a shift in corporate responsibility—an acknowledgment that businesses must be accountable for their broader impact on society and the environment, not just their bottom line.

By expanding on the requirements set by the NFRD, the CSRD obliges companies to go beyond financial disclosures and provide detailed information about their ESG impacts. This includes reporting on issues such as carbon emissions, climate change mitigation strategies, social responsibilities, and governance practices. This information is crucial for investors, consumers, and stakeholders in evaluating a company’s true sustainability footprint.

CSRD Meaning: The Importance of Transparency

At its core, the CSRD demands transparency. For instance, IR Magazine highlights in their article that ESG data is now considered “table stakes” or critical for competitive differentiation by a significant majority of firms. 89% of respondents in one survey viewed ESG data as either essential to keep pace with competitors or critical for their firm’s competitive edge. 

As more stakeholders prioritize sustainability, the CSRD ensures businesses can no longer gloss over their environmental and social responsibilities. Companies that don’t provide transparent and comparable data risk losing investor trust and facing reputational damage. 

On the other hand, those that embrace this have a great opportunity to position themselves as leaders in the sustainable business landscape.

Key Features of the CSRD

The Corporate Sustainability Reporting Directive introduces several key features designed to enhance corporate accountability and transparency:

Enhanced Transparency

Under the CSRD, companies are required to standardize the reporting of their sustainability efforts. This change enables stakeholders to make informed comparisons across industries. Take, for example, a company that has long reported its climate impacts in a transparent manner.

Double Materiality

The principle of double materiality expands corporate reporting beyond financial impacts. Companies must report both how ESG factors affect their financial health and how their operations impact society and the environment. A company reporting on carbon emissions not only discusses the risks it faces due to climate change but also how its emissions contribute to global warming.

Auditing Requirements

One of the significant changes brought by the CSRD is the requirement for third-party auditing of sustainability reports. This ensures that the disclosed information is accurate, making the reported data trustworthy. With sustainability becoming a competitive differentiator, the inclusion of independent audits prevents businesses from overstating their ESG achievements.

Who Needs to Comply with CSRD?

The CSRD broadens its reach to nearly 50,000 companies, consisting of large EU firms and international companies with significant EU operations. This includes companies that meet at least two criteria: over 250 employees, €40 million in turnover, or €20 million in assets.

For example, multinational corporations like Amazon and Shell, with extensive European operations, will now fall under this directive, as will listed small- and medium-sized enterprises (SMEs) starting in 2026.

The expanded scope means that even international companies with subsidiaries or branches in the EU will be subject to these requirements if they meet certain thresholds. The global impact of the CSRD is significant, as businesses operating in multiple regions will need to align with these new sustainability standards, contributing to more consistent and comparable ESG data worldwide.

CSRD for Non-EU Companies

The Corporate Sustainability Reporting Directive (CSRD) impacts not only EU-based businesses but also non-EU companies with significant operations within the European Union. Understanding these new regulations is crucial to stay compliant and align your business with sustainability goals.

If you missed our live session, you can still access the valuable insights shared by industry experts. Watch the recording of our webinar on CSRD for Non-EU Companies to learn about the steps your company should take to meet CSRD requirements and ensure you’re up to date in the evolving landscape of ESG reporting.

CSRD Reporting Requirements

CSRD introduces far more comprehensive reporting requirements compared to its predecessor. Companies must disclose their impact on various ESG metrics, such as carbon emissions, resource management, and biodiversity.

If you’re running a company you will need to detail your progress toward net-zero emissions goals or human rights practices across the entire value chain. By digitizing reports with XBRL standards, companies can make sure that stakeholders have easy access and can analyze this information, further enhancing transparency.

Timeline for CSRD Implementation

The CSRD will be implemented in a phased manner, giving companies time to prepare for the new reporting standards:

  • January 1, 2024: Large public-interest companies begin reporting for the fiscal year 2024.
  • January 1, 2025: All other large companies start reporting for the fiscal year 2025.
  • January 1, 2026: Listed SMEs begin reporting for the fiscal year 2026.
  • January 1, 2028: Non-EU companies with significant EU operations will start reporting for the fiscal year 2028.

In other words, the deadline has already passed for the largest companies and the clock is ticking for every business to align with CSRD requirements. While listed SMEs won’t need to report until 2026, it’s crucial that all companies start preparing now. Organizations should begin by assessing their current ESG reporting capabilities and consider adopting digital reporting tools like CEMAsys’ software to streamline the process. Early adopters of the CSRD will not only stay compliant but also gain a competitive edge in the marketplace.

Implications of the CSRD for Businesses

For businesses, the implications of the CSRD are clear—compliance is non-negotiable. First and foremost, it increases the pressure on companies to accurately track, report, and improve their ESG performance. As stakeholders place greater importance on sustainability, businesses that fail to comply with CSRD requirements may face reputational damage, legal consequences, and loss of investor confidence.

However, for companies that embrace the CSRD, there are clear benefits. By providing transparent, reliable ESG data, businesses can improve their reputation, attract sustainable investment, and better align themselves with consumer and regulatory demands for greater corporate responsibility. Moreover, companies that lead in sustainability are often better positioned to innovate and respond to the global shift towards greener, more responsible business practices.
