What Is the GHG Protocol and Who Uses It

If your company has started on the path to sustainability reporting, you have almost certainly encountered the term “GHG Protocol.” It appears in regulatory guidance, investor questionnaires, exchange listing requirements, and sustainability reports from virtually every major corporation. But for operations teams and finance leaders in industrial businesses, understanding what the GHG Protocol actually requires, and how to implement it in practice, can feel less straightforward than the guidance documents suggest.

The GHG Protocol, formally known as the Greenhouse Gas Protocol, is the world’s most widely used standard for measuring and managing greenhouse gas emissions. It was developed jointly by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), and its first corporate standard was published in 2001. Since then, it has become the foundational methodology that underpins virtually every major carbon reporting framework in use today.

The protocol’s importance lies not just in what it measures, but in how it organises the measurement. It classifies greenhouse gas emissions into three distinct scopes, each capturing a different category of an organisation’s climate impact. This classification system provides a common language that allows companies, regulators, investors, and supply chain partners to communicate about emissions in a standardised and comparable way.

Who relies on the GHG Protocol

The reach of the GHG Protocol extends far beyond any single industry or geography. It is used by national and local governments, multinational corporations, financial institutions, and standards bodies around the world. In Asia, its influence is particularly significant for the sectors that form the backbone of regional manufacturing economies.

In Singapore, the National Environment Agency’s mandatory GHG reporting framework draws directly on GHG Protocol methodologies. Listed companies on the Singapore Exchange are expected to report their Scope 1 and Scope 2 emissions, and increasingly their material Scope 3 categories, using the protocol’s accounting principles. The Monetary Authority of Singapore’s environmental risk management guidelines also reference GHG Protocol-aligned reporting as a benchmark for financial institutions assessing climate risk.

Taiwan’s Financial Supervisory Commission requires listed companies to disclose greenhouse gas emissions, and the Taiwan Stock Exchange has progressively expanded these requirements. For semiconductor fabs and electronics manufacturers in Taiwan, many of which supply global technology brands, GHG Protocol reporting is effectively a condition of doing business with international customers who have their own emissions disclosure commitments.

Thailand, Indonesia, and Malaysia are at various stages of developing their regulatory frameworks for carbon reporting. In each case, the GHG Protocol is either explicitly referenced or serves as the implicit standard that local guidelines are designed around. For petrochemical plants in Thailand, steel mills in Indonesia, and electronics manufacturers in Malaysia, building GHG Protocol-compliant reporting systems now means being prepared for the regulations that are coming, rather than scrambling to respond after they arrive.

Beyond regulators, the GHG Protocol is used by the International Sustainability Standards Board (ISSB) as the basis for the emissions disclosure requirements in IFRS S2. It underpins the European Union’s Corporate Sustainability Reporting Directive (CSRD) through the European Sustainability Reporting Standards. It is referenced by the Science Based Targets initiative (SBTi), which requires companies to set emissions reduction targets consistent with the Paris Agreement. And it is used by major accounting firms and assurance providers as the standard against which emissions data is verified.

In practical terms, if your company needs to report its carbon emissions to any stakeholder, whether a regulator, an investor, a customer, or a voluntary initiative, the GHG Protocol is the methodology you will be expected to follow.

The five accounting principles

The GHG Protocol is built on five core accounting principles that apply to all emissions measurement and reporting:

– Relevance: Ensure the GHG inventory appropriately reflects the company’s emissions and serves the decision-making needs of users, both internal and external

– Completeness: Account for all emission sources and activities within the chosen inventory boundary, disclosing and justifying any specific exclusions

– Consistency: Use consistent methodologies to allow for meaningful comparisons of emissions over time

– Transparency: Disclose all relevant assumptions and provide sufficient context for users to understand the underlying data and decisions

– Accuracy: Ensure that the quantification of emissions is systematic and does not over- or under-estimate actual emissions, to the extent that is practically achievable

These principles are not abstract ideals. They are practical requirements that directly affect the credibility and usefulness of your emissions data. When a CSO presents emissions figures to the board, or a CFO includes them in a financing application, the confidence that stakeholders place in those numbers depends on how well the underlying data satisfies these five principles. This is why at Evercomm, we build these principles into every stage of our data pipeline, from IoT sensor deployment to the production of assured reports.

Scope 1: Direct Emissions from Manufacturing Operations

Scope 1 emissions are, in many respects, the most tangible and directly controllable category of greenhouse gas emissions. They are the emissions that come from sources that are owned or controlled by your company. For industrial operations, this category typically represents a significant share of total reported emissions, and it is the area where operational changes can have the most immediate and measurable impact.

Understanding what falls within Scope 1, and how to measure it accurately, is the essential first step in building a compliant GHG inventory.

Sources of Scope 1 emissions in industry

For manufacturing, semiconductor, steel, and petrochemical operations, the primary sources of Scope 1 emissions fall into four broad categories:

– Stationary combustion: This is the largest source of Scope 1 emissions for most industrial facilities. It includes the burning of natural gas in boilers and furnaces, the combustion of diesel or fuel oil in backup generators, and the use of coal or biomass in on-site power generation. For a petrochemical plant in Thailand or a steel mill in Indonesia, stationary combustion can account for the majority of direct emissions

– Mobile combustion: Emissions from vehicles owned or controlled by the company, including delivery trucks, forklifts, company cars, and any other mobile equipment that burns fuel. This category is typically smaller than stationary combustion for heavy industry, but it is still a material source that needs to be accounted for accurately

– Process emissions: Some industrial processes release greenhouse gases as a direct by-product of chemical reactions, rather than through combustion. In the semiconductor industry, perfluorocarbons (PFCs), nitrogen trifluoride (NF3), and sulphur hexafluoride (SF6) are used in manufacturing processes and are released during chamber cleaning and etching. In the steel industry, process emissions from the reduction of iron ore are a major source of CO2. In petrochemical refining, process emissions arise from flaring, venting, and fugitive releases

– Fugitive emissions: These are unintentional releases of greenhouse gases from equipment such as valves, flanges, pumps, and storage tanks. In petrochemical and chemical manufacturing, fugitive emissions of methane and other gases can be substantial, and they are among the most difficult sources to measure accurately

Measuring Scope 1 accurately

The accuracy of Scope 1 reporting depends fundamentally on the quality of the underlying activity data. There are two broad approaches to collecting this data, and the distinction between them has significant implications for the reliability of your emissions inventory.

The first approach relies on fuel purchase records and engineering estimates. You know how much natural gas your facility purchased in a given period, and you apply a standard emission factor to convert that volume into CO2 equivalent. This approach is common, relatively straightforward, and is often acceptable for initial reporting. However, it has inherent limitations. Fuel purchases do not always match actual consumption, particularly when tanks are being filled or drawn down across reporting period boundaries. Engineering estimates for process emissions and fugitive releases are, by definition, approximations that may not reflect actual operating conditions.

The second approach uses direct measurement through IoT sensors and continuous monitoring systems. This is where the most significant improvements in data quality are being achieved. Real-time monitoring solutions, such as Evercomm’s NxOps platform, deploy IoT sensors directly on boilers, furnaces, generators, and process equipment to capture actual fuel consumption, energy use, and process parameters as they occur. This data is transmitted continuously to a central platform, eliminating the time lag associated with manual collection and providing a complete, auditable record of facility operations.

The practical difference between these two approaches is substantial. We have encountered industrial facilities where the gap between estimated and measured Scope 1 emissions was significant enough to affect the credibility of the entire emissions inventory. Direct measurement not only improves accuracy, it also provides the operational intelligence needed to identify inefficiencies and drive reductions. When you can see, in real time, which equipment is consuming more fuel than expected, you can take corrective action immediately rather than waiting for the next reporting cycle.

For semiconductor manufacturers in Taiwan and Singapore, where process emissions of high-global-warming-potential gases are a critical concern, direct measurement is increasingly becoming the expected standard rather than a best-practice aspiration. Regulators and customers alike are asking for data that reflects actual process conditions, not theoretical estimates.

Scope 2: Market-Based vs Location-Based Electricity Emissions

Scope 2 emissions are the indirect greenhouse gas emissions that result from the generation of purchased electricity, steam, heating, and cooling consumed by your company. For many industrial operations, particularly those in sectors like semiconductor manufacturing and electronics assembly where electricity is the dominant energy input, Scope 2 can represent the largest single category of reported emissions.

The GHG Protocol introduced a significant update to Scope 2 accounting in 2015, when it introduced the dual reporting framework that requires companies to report both location-based and market-based Scope 2 emissions. Understanding the difference between these two methods, and when each is appropriate, is essential for accurate and compliant reporting.

Location-based Scope 2 emissions

The location-based method reflects the average emission intensity of the electricity grid serving your facility. It uses a grid-average emission factor, which is typically published by national energy authorities or international databases. This method tells you and your stakeholders what the emissions impact of your electricity consumption is, based on the overall mix of generation sources in your region.

For a manufacturing facility in Singapore, the location-based emission factor reflects the country’s generation mix, which is heavily reliant on natural gas. For a facility in Indonesia, the factor will be different, reflecting a higher proportion of coal-fired generation. For a facility in Taiwan, it will vary depending on the proportion of nuclear, coal, natural gas, and renewable generation in the grid at the time.

Location-based reporting provides a consistent and comparable measure of the emissions associated with your electricity consumption, regardless of any specific purchasing decisions your company has made. It is the default method and is always required as part of a complete GHG Protocol inventory.

Market-based Scope 2 emissions

The market-based method reflects the emissions impact of the electricity that your company has specifically chosen to purchase. If your company buys renewable energy through a power purchase agreement (PPA), purchases renewable energy certificates (RECs), or participates in a green tariff programme offered by your utility, the market-based method allows you to report the emissions associated with those specific contractual instruments, rather than the grid average.

In practice, this means that a company with a robust renewable energy procurement strategy can report significantly lower market-based Scope 2 emissions than location-based emissions. A semiconductor fab in Singapore that has signed a long-term PPA for solar energy, for example, would report its location-based emissions using the Singapore grid average, and its market-based emissions based on the contractual attributes of the PPA.

Both figures are required. The location-based figure provides the baseline that reflects the physical reality of grid-connected consumption. The market-based figure reflects the company’s procurement decisions and its contribution to driving renewable energy generation. Together, they give stakeholders a complete picture.

Practical considerations for Asian industrial facilities

For industrial companies operating across Asia, Scope 2 reporting presents some specific challenges. Renewable energy markets are at different stages of development in different countries. In Singapore, the market for corporate PPAs and RECs is maturing rapidly, and several major industrial energy users have signed long-term agreements. In Taiwan, the government has introduced renewable energy certificate programmes that allow companies to offset their grid electricity emissions. In Thailand, Indonesia, and Malaysia, the availability and regulatory treatment of renewable energy instruments varies, and companies need to understand the specific rules in each jurisdiction.

The key practical advice is to maintain detailed records of all electricity procurement contracts, including PPA terms, REC purchases, and green tariff arrangements. This documentation is essential for supporting market-based claims and for withstanding scrutiny during assurance engagements. A carbon accounting platform that can handle both location-based and market-based calculations, and maintain the audit trail linking each reported figure to its underlying contractual basis, is not a luxury. It is a necessity.

NxMap, Evercomm’s carbon accounting platform, is designed to manage exactly this complexity. It applies the correct emission factors for each facility’s location, tracks contractual instruments for market-based reporting, and maintains a complete audit trail from source data to reported figures. For companies with facilities in multiple Asian countries, this capability is essential for producing consolidated emissions inventories that are consistent, comparable, and compliant.

Scope 3: Value Chain Emissions That Matter Most

Scope 3 is the broadest and most complex of the three emissions categories. It covers all indirect emissions that occur in a company’s value chain, both upstream and downstream. For many industrial companies, Scope 3 emissions are the largest share of their total carbon emissions, often representing 70% to 90% of the total. Yet they are also the most challenging to measure, because they occur outside the company’s direct control.

The GHG Protocol’s Corporate Value Chain (Scope 3) Standard divides Scope 3 into 15 categories, grouped into upstream and downstream activities. Understanding which of these categories are material to your business is critical for building an efficient and meaningful Scope 3 inventory.

The 15 Scope 3 categories

The upstream categories, covering emissions that occur before your product reaches your facility, include:

– Category 1: Purchased goods and services — Emissions from the production of raw materials, components, and services that your company buys

– Category 2: Capital goods — Emissions from the production of assets such as machinery, buildings, and vehicles

– Category 3: Fuel and energy-related activities — Emissions from the extraction, production, and transportation of fuels and energy purchased by the company, not including the combustion itself (which is Scope 1)

– Category 4: Upstream transportation — Emissions from the transportation of purchased goods and materials to your facility

– Category 5: Waste generated in operations — Emissions from the treatment and disposal of waste produced by your operations

– Category 6: Business travel — Emissions from employee travel for business purposes

– Category 7: Employee commuting — Emissions from employees travelling between their homes and workplaces

– Category 8: Upstream leased assets — Emissions from the operation of assets that your company leases but does not own

The downstream categories, covering emissions that occur after your product leaves your facility, include:

– Category 9: Downstream transportation — Emissions from the transportation and distribution of your products

– Category 10: Processing of sold products — Emissions from further processing of your products by other companies

– Category 11: Use of sold products — Emissions from the use of your products by end consumers

– Category 12: End-of-life treatment — Emissions from the disposal or recycling of your products at the end of their life

– Category 13: Downstream leased assets — Emissions from the operation of assets that your company owns and leases to others

– Category 14: Franchises — Emissions from the operation of franchises

– Category 15: Investments — Emissions from the operation of investments, such as equity investments and project finance

Which categories matter most for your industry

The GHG Protocol does not require companies to measure all 15 categories with equal precision. It recommends a screening assessment to identify which categories are expected to be material, and to focus measurement efforts accordingly. For industrial companies in Asia, the material categories tend to cluster around a few key areas.

For semiconductor manufacturers, purchased goods and services (Category 1) and capital goods (Category 2) are typically the largest Scope 3 sources, reflecting the emissions intensity of raw materials such as silicon wafers, specialty gases, and chemicals. The use of sold products (Category 11) may also be significant, depending on the energy consumption of the end-use devices that incorporate the company’s components.

For steel manufacturers, the use of sold products (Category 11) is often the dominant category, because the steel produced is used in construction, automotive, and industrial applications that consume energy and generate emissions during their use phase. Purchased goods and services (Category 1), particularly raw materials such as iron ore and coal, are also typically material.

For petrochemical companies, the picture is similarly complex. Purchased goods and services, upstream transportation, and the use of sold products can all be material categories. Process emissions, while classified as Scope 1 when they occur at the company’s own facilities, may also arise at supplier facilities and contribute to Category 1.

The practical guidance is to start with a screening assessment using available data, industry benchmarks, and spend-based estimation methods. This will give you a directional understanding of where your Scope 3 emissions are concentrated. You can then prioritise the most material categories for more detailed measurement, using supplier-specific data where available and average data where it is not.

The growing regulatory expectation for Scope 3

Until recently, many companies focused their emissions reporting on Scope 1 and Scope 2, treating Scope 3 as a future concern. That position is becoming increasingly difficult to maintain. The ISSB’s IFRS S2 standard requires disclosure of material Scope 3 emissions. The EU’s CSRD requires Scope 3 reporting for companies within its scope. The SBTi requires companies to include Scope 3 in their science-based targets.

For Asian industrial companies supplying European or North American markets, Scope 3 reporting is no longer optional. Your customers are being required to report their own Scope 3 emissions, which means they need emissions data from their suppliers. If you cannot provide this data, you risk being excluded from supply chains.

The good news is that building a Scope 3 inventory does not need to be an all-or-nothing exercise. Starting with a screening assessment, focusing on the most material categories, and progressively improving data quality over time is an accepted and practical approach. The GHG Protocol itself acknowledges that Scope 3 accounting involves uncertainty and encourages companies to be transparent about their estimation methods and data limitations.

GHG Protocol Calculation Methodologies for Energy-Intensive Industries

The basic formula for calculating greenhouse gas emissions under the GHG Protocol is straightforward: activity data multiplied by an emission factor. In practice, however, the application of this formula in energy-intensive industrial settings requires careful attention to a range of technical factors.

Activity data collection

Activity data is the quantitative measure of the activity that generates emissions. For combustion sources, this is typically the volume or mass of fuel consumed. For purchased electricity, it is the quantity of electricity consumed. For process emissions, it may be the quantity of a specific chemical used or the volume of a gas released.

The quality of your activity data is the single most important determinant of the accuracy of your emissions inventory. There are several tiers of data quality recognised by the GHG Protocol, ranging from primary data collected through direct measurement to secondary data based on industry averages and spend-based estimates.

For energy-intensive industries, the priority should be to move from secondary to primary data wherever possible. This means:

– Installing flow meters on fuel lines to measure actual consumption rather than relying on delivery records

– Deploying IoT sensors on boilers, furnaces, and generators to capture real-time operational data through solutions like NxOps

– Submetering electricity consumption at the process level, rather than relying on a single utility meter for an entire facility

– Implementing continuous emissions monitoring systems (CEMS) for major point sources where process emissions are significant

The investment in primary data collection delivers value beyond compliance. It provides the operational intelligence needed to identify inefficiencies, optimise processes, and reduce both emissions and costs. When a steel mill can see, in real time, which production lines are consuming the most energy per unit of output, it can make operational adjustments that improve both environmental and financial performance.

Emission factor selection

Emission factors convert activity data into greenhouse gas emissions, typically expressed in tonnes of CO2 equivalent (tCO2e). The choice of emission factor depends on the type of activity, the fuel or material involved, and the geographic location.

The GHG Protocol provides guidance on emission factor selection, and there are several authoritative sources that companies can draw on:

– The IPCC Emission Factor Database provides default emission factors for various fuel types and industrial processes

– National energy authorities, such as Singapore’s National Environment Agency and Taiwan’s Environmental Protection Administration, publish country-specific emission factors

– Industry associations, such as the World Steel Association and SEMI for semiconductors, provide sector-specific emission factors and calculation guidance

– Electricity grid emission factors are published by national grid operators or international databases such as the International Energy Agency

For global warming potential (GWP) values, the GHG Protocol recommends using the values from the IPCC Assessment Reports. It is important to be consistent in the GWP values used across the inventory, and to clearly disclose which set of values has been applied. Switching between different GWP reporting periods without adjustment can introduce inconsistencies that undermine comparability.

Global warming potential and CO2 equivalent

The GHG Protocol requires emissions to be reported in CO2 equivalent (CO2e), which is a standardised unit that allows different greenhouse gases to be aggregated into a single figure. Each greenhouse gas has a global warming potential (GWP) that expresses how much heat it traps in the atmosphere relative to CO2 over a specified time period, typically 100 years.

For industrial operations, the most relevant greenhouse gases include:

– Carbon dioxide (CO2): GWP of 1, the reference gas

– Methane (CH4): GWP of approximately 28, relevant for fugitive emissions in petrochemical and natural gas operations

– Nitrous oxide (N2O): GWP of approximately 265, relevant for certain chemical production processes

– Perfluorocarbons (PFCs): GWPs ranging from several thousand to over 10,000, relevant for semiconductor manufacturing

– Sulphur hexafluoride (SF6): GWP of approximately 23,500, used in electrical equipment and some industrial processes

– Nitrogen trifluoride (NF3): GWP of approximately 16,100, used in semiconductor and display manufacturing

The extremely high GWPs of some of these gases mean that even small quantities can have a significant impact on a company’s total reported emissions. For semiconductor manufacturers, PFCs and NF3 can account for a substantial share of Scope 1 emissions despite being used in relatively small volumes. Accurate measurement and management of these gases is therefore critical for both compliance and operational performance.

Building a Compliant GHG Inventory Step by Step

Building a GHG Protocol-compliant inventory is a structured process that, when approached methodically, is both manageable and repeatable. The following steps outline the approach that we recommend for industrial companies in Asia, drawing on our experience working with manufacturers, semiconductor fabs, steel producers, and petrochemical plants across the region.

Step 1: Define your organisational and operational boundaries

Before you can measure your emissions, you need to define what you are measuring. The GHG Protocol requires companies to establish two boundaries:

The organisational boundary determines which operations are included in the inventory. The GHG Protocol offers two consolidation approaches: the equity share approach, which accounts for emissions from joint ventures and subsidiaries in proportion to your equity stake, and the control approach, which accounts for 100% of emissions from operations over which you have either financial or operational control. Most industrial companies use the control approach.

The operational boundary determines which emission sources within the organisational boundary are included, categorised by scope. This is where you identify all your Scope 1, Scope 2, and material Scope 3 sources.

For a manufacturing company with facilities in Singapore, Malaysia, and Indonesia, this step involves mapping each facility, identifying the emission sources at each site, and determining which scope each source falls into. It is worth investing time in this step, because gaps in the boundary definition lead to gaps in the inventory that are difficult and costly to correct later.

Step 2: Collect activity data

With the boundaries defined, the next step is to collect the activity data needed for each emission source. This includes fuel consumption records, electricity bills, process chemical usage logs, transportation data, and waste disposal records.

The quality of your data collection processes directly determines the quality of your emissions inventory. As discussed earlier, the priority should be to use primary data wherever possible, supported by direct measurement systems. For facilities where primary data is not yet available, secondary data from industry averages or spend-based estimates can be used as a starting point, with a clear plan for progressive improvement.

This is where the combination of NxOps for real-time data capture and NxMap for data processing becomes particularly valuable. NxOps captures actual operational data from IoT sensors deployed across your facilities, providing the primary data that underpins a high-quality inventory. NxMap then processes this data using the appropriate emission factors and methodologies, maintaining the audit trail that assurance providers require.

Step 3: Apply emission factors and calculate emissions

With activity data in hand, the next step is to apply the appropriate emission factors to calculate emissions for each source. This involves selecting the correct emission factor for each fuel type, electricity grid, and process, applying the relevant GWP values, and aggregating the results by scope and by greenhouse gas.

Attention to detail matters here. Using an outdated emission factor, or applying the wrong GWP value, can introduce errors that propagate through the entire inventory. A carbon accounting platform that is maintained with up-to-date emission factors and GWP values reduces this risk significantly.

Step 4: Verify and validate

Verification is the process of checking that your inventory is accurate, complete, and consistent. Internal verification involves reviewing the data, calculations, and assumptions for errors and inconsistencies. External verification involves engaging an independent third party, such as Bureau Veritas, to provide assurance on your reported emissions.

External verification to ISO 14064 is increasingly expected by regulators and investors. Evercomm holds ISO 14064 certification and works with Bureau Veritas to provide verified emissions data for our clients. This means that the inventories we help build are not just accurate, they are independently assured, giving stakeholders confidence that the reported figures are reliable.

Verification also builds internal confidence. When a CFO presents emissions data to the board, or when a CSO reports against a science-based target, knowing that the numbers have been independently verified provides a level of assurance that is difficult to achieve through internal processes alone.

Step 5: Report, improve, and iterate

The final step is to compile the verified emissions data into reports that meet the requirements of your relevant frameworks and stakeholders. This may include a sustainability report for your exchange listing requirements, a disclosure aligned with ISSB standards, a response to a customer questionnaire, or a submission to a voluntary initiative such as the CDP.

The key principle is to treat the inventory as a living system, not a one-off exercise. Each reporting cycle should build on the previous one, with improvements in data quality, expanded Scope 3 coverage, and updated emission factors. Over time, the inventory becomes increasingly comprehensive and increasingly accurate, providing a solid foundation for both compliance and strategic decision-making.

With the right systems in place, this iterative process becomes manageable rather than burdensome. Companies using automated data collection and carbon accounting platforms have reported up to 80% faster reporting cycles, freeing their teams to focus on analysis and action rather than data wrangling.

How the GHG Protocol Aligns with ISSB and CSRD Requirements

One of the most common questions we hear from CFOs and CSOs is whether the effort invested in GHG Protocol reporting will carry over to newer disclosure requirements such as the ISSB standards and the EU’s CSRD. The answer is encouragingly positive.

ISSB IFRS S2 and the GHG Protocol

The ISSB’s IFRS S2 standard, which focuses on climate-related disclosures, explicitly references the GHG Protocol as the basis for its emissions disclosure requirements. IFRS S2 requires companies to disclose their Scope 1, Scope 2, and material Scope 3 greenhouse gas emissions, using the GHG Protocol’s classification system and accounting methodologies.

This means that a company with a well-constructed GHG Protocol inventory is already meeting the emissions measurement requirements of IFRS S2. The additional requirements of IFRS S2 relate primarily to disclosure, including governance, strategy, risk management, and targets and metrics, rather than to the underlying emissions accounting.

For Asian companies that may be subject to ISSB-aligned requirements through their local regulators, such as SGX in Singapore, this alignment is particularly valuable. Building your emissions inventory on the GHG Protocol foundation means that you are prepared for ISSB compliance without needing to re-engineer your data systems.

CSRD and the European Sustainability Reporting Standards

The EU’s Corporate Sustainability Reporting Directive (CSRD) is one of the most comprehensive sustainability disclosure frameworks in the world. While it applies primarily to EU-based companies, its reach extends to non-EU companies that have significant revenue from EU operations or are listed on EU-regulated markets. For Asian manufacturers exporting to Europe, CSRD compliance is an increasingly relevant consideration.

The European Sustainability Reporting Standards (ESRS) that underpin the CSRD draw heavily on the GHG Protocol for emissions accounting. ESRS E1 (Climate Change) requires disclosure of gross Scope 1, Scope 2, and material Scope 3 GHG emissions, using the GHG Protocol’s methodology as the basis. The CSRD also requires information on the GHG Protocol’s three scopes to be presented in a way that is consistent with its classification system.

Again, the practical implication is clear: a GHG Protocol-compliant inventory is the foundation upon which CSRD-aligned reporting can be built. Companies that invest in robust GHG Protocol accounting now will be well positioned to respond to CSRD requirements as they become applicable.

Building a future-proof emissions data system

The convergence of major disclosure frameworks around the GHG Protocol’s classification system and accounting principles means that the investment you make in your emissions data infrastructure today will serve you across multiple current and future reporting requirements.

Rather than building separate data systems for each framework, the efficient approach is to build a single, high-quality GHG Protocol inventory and then use it as the basis for generating reports that satisfy multiple frameworks. This is precisely the approach that NxMap is designed to support. By applying GHG Protocol methodologies as the foundation, and then structuring outputs to meet the specific requirements of the ISSB, CSRD, SGX, and other frameworks, NxMap enables companies to produce compliant reports from a single verified dataset.

The regulatory landscape in Asia is evolving quickly. Singapore, Taiwan, Thailand, Indonesia, and Malaysia are all moving towards more comprehensive and prescriptive emissions disclosure requirements. The companies that will navigate this transition most successfully are those that invest now in robust, GHG Protocol-aligned data systems that can adapt to whatever specific requirements emerge.

The assurance imperative

Both the ISSB and CSRD frameworks are moving towards requiring or strongly encouraging third-party assurance of emissions data. This reflects a broader trend: stakeholders are no longer satisfied with self-reported numbers. They want independent verification that the data is accurate, complete, and prepared in accordance with recognised standards.

For industrial companies, this means that building a GHG Protocol inventory is not just about getting the calculations right. It is about building the systems, controls, and documentation that allow an independent assurance provider to verify your numbers with confidence. This includes maintaining clear audit trails, documenting data sources and methodologies, and having robust internal review processes.

Evercomm’s approach is designed with assurance in mind from the outset. Our data pipeline, from IoT sensors to verified reports, is built to produce emissions data that meets the evidentiary standards required by Bureau Veritas and other leading assurance providers. With up to 90% data authenticity achieved through direct measurement and automated processing, and up to 80% faster reporting cycles, we enable our clients to produce assured reports that satisfy the most demanding stakeholders.

Getting Started with GHG Protocol Compliance

Building a GHG Protocol-compliant emissions inventory is not a one-time project. It is the foundation of a continuous process of measurement, improvement, and disclosure that will increasingly define how industrial companies are evaluated by regulators, investors, customers, and the broader market.

The journey begins with understanding where your emissions come from, collecting accurate data on those sources, and applying the GHG Protocol’s methodologies consistently and transparently. It progresses through verification, disclosure, and iterative improvement. And it culminates in a data system that not only satisfies compliance requirements but provides the actionable data needed to drive operational improvements, reduce emissions, and strengthen your company’s position in an increasingly sustainability-conscious market.

For CFOs, the value proposition is clear: a well-built GHG inventory reduces compliance risk, improves access to sustainable finance, and supports more informed capital allocation decisions. For CSOs, it provides the credible, verifiable data needed to set and report against meaningful targets. For Operations Directors, it delivers the real-time operational intelligence needed to identify and eliminate inefficiencies.

At Evercomm, we have guided industrial enterprises across Singapore, Taiwan, Thailand, Indonesia, and Malaysia through this journey. As a certified B Corporation with a B Impact Score of 94.6, ISO 14064 certification, and Bureau Veritas verification, we bring both the technical capability and the institutional credibility to support your GHG Protocol compliance from start to finish.
