The push towards sustainability is reshaping how companies operate globally, and Malaysia is no exception. As businesses align with national and international climate goals, understanding their environmental impact becomes crucial. Greenhouse Gas (GHG) accounting is the first essential step on this journey. It provides the data-driven foundation for any meaningful action toward reducing emissions and achieving net zero.

This guide offers a practical roadmap for businesses in Malaysia looking to implement GHG accounting. We will explore why it matters, navigate the local regulatory landscape, and outline the concrete steps you can take to measure your carbon footprint. By mastering GHG accounting, your organization can build a credible and effective sustainability strategy.

Why GHG Accounting is a Business Imperative

GHG accounting is more than just an environmental exercise; it's a strategic business function. It involves quantifying the total greenhouse gases produced directly and indirectly from a company's operations. This process, often called carbon footprint measurement, provides the critical data needed to manage environmental risks and unlock new opportunities.

Gaining a Competitive Edge

In an increasingly eco-conscious market, demonstrating a commitment to sustainability can set your business apart. Customers, especially younger generations, prefer brands that are transparent about their environmental impact. A verified GHG inventory can enhance your brand reputation, build trust with consumers, and attract top talent who want to work for responsible companies. This proactive stance can also open doors to new markets and partnerships with other forward-thinking organizations.

Meeting Investor and Stakeholder Demands

Investors are now scrutinizing environmental, social, and governance (ESG) performance as a key indicator of a company's long-term viability. They use GHG emissions data to assess climate-related risks and a company's readiness for a low-carbon economy. By implementing robust GHG accounting, you provide stakeholders with the transparent data they demand, potentially improving access to capital and lowering financing costs. It signals that your management is proactive, forward-looking, and capable of navigating future challenges.

Preparing for Future Regulations

The regulatory landscape for carbon emissions is tightening worldwide. By voluntarily adopting GHG accounting now, your business can get ahead of potential mandatory reporting requirements in Malaysia. Early adoption allows you to build internal capacity, refine your data collection processes, and integrate sustainability practices into your core operations smoothly. This foresight minimizes the risk of future compliance penalties and ensures a seamless transition as regulations evolve.

The Regulatory Landscape for GHG Reporting in Malaysia

While Malaysia is still developing a comprehensive, mandatory framework for GHG reporting across all sectors, several key policies and initiatives are paving the way. Understanding this evolving landscape is vital for any business planning its net zero journey.

National Commitments and Policies

Malaysia has committed to ambitious climate targets, including becoming a carbon-neutral nation by as early as 2050. The nation updated its Nationally Determined Contribution (NDC) under the Paris Agreement, pledging to reduce its economy-wide carbon intensity against GDP by 45% by 2030 compared to 2005 levels. These national goals are creating a top-down push for corporate climate action.

The National Energy Transition Roadmap (NETR) further outlines strategies to shift Malaysia towards cleaner energy sources, which will directly impact business operations and supply chains. As these policies are implemented, companies will face increasing pressure to align their own targets with the national agenda.

Bursa Malaysia's Reporting Requirements

For publicly listed companies (PLCs), the push for transparency is already here. Bursa Malaysia has enhanced its Sustainability Reporting Framework, requiring PLCs to disclose more detailed information on their ESG performance. This includes reporting on material climate-related risks and opportunities.

Starting from the financial year ending 2024, Main Market PLCs are required to provide climate change-related disclosures aligned with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations. This includes reporting Scope 1 and Scope 2 GHG emissions. ACE Market-listed corporations will need to follow suit by 2026. This mandate makes GHG accounting an essential compliance activity for a significant portion of Malaysia's corporate sector.

Voluntary Programs and Incentives

The Malaysian government and various agencies encourage voluntary action. The Malaysia Green Technology and Climate Change Corporation (MGTC) runs programs like the National GHG Inventory, offering guidance and resources for companies looking to start their carbon footprint measurement. Additionally, incentives such as the Green Investment Tax Allowance (GITA) and Green Income Tax Exemption (GITE) support investments in green technologies that can help reduce a company's carbon footprint.

A Step-by-Step Guide to GHG Accounting

Implementing GHG accounting can seem daunting, but breaking it down into manageable steps makes the process achievable. Following a structured approach ensures your data is accurate, consistent, and useful for decision-making.

Step 1: Define Your Organisational and Operational Boundaries

The first step is to decide what to include in your inventory.

• Organisational Boundaries: Determine which parts of your company will be covered. Will you report on the entire parent company, specific subsidiaries, or joint ventures? The two main approaches are the equity share approach (accounting for emissions based on your ownership percentage) and the control approach (accounting for 100% of emissions from operations you control).
• Operational Boundaries: Identify all the emission sources associated with your operations. This is where the concept of "Scopes" comes in. The GHG Protocol, the most widely used international accounting tool, categorizes emissions into three scopes:

• Scope 1: Direct Emissions: These are emissions from sources owned or controlled by your company. Examples include fuel combustion in company vehicles, boilers, and furnaces, as well as emissions from chemical production.
• Scope 2: Indirect Emissions from Purchased Energy: These are emissions from the generation of purchased electricity, steam, heating, and cooling consumed by your company.
• Scope 3: Other Indirect Emissions: This is the broadest category, covering all other indirect emissions that occur in your company's value chain. Examples include purchased goods and services, business travel, employee commuting, waste disposal, and the use of your sold products.

For businesses starting, focusing on Scope 1 and Scope 2 is a practical first goal. As your capabilities mature, you can progressively expand your reporting to include relevant Scope 3 categories.

Step 2: Collect Activity Data

Once you have defined your boundaries, the next phase is to gather data. This "activity data" represents the measure of activity that results in GHG emissions. The type of data you need depends on the emission source.

• For Scope 1: This includes records of fuel consumption (liters of diesel for trucks, cubic meters of natural gas for boilers), records of refrigerant usage for air conditioning systems, and data on industrial process emissions.
• For Scope 2: This is typically your electricity bills from providers like Tenaga Nasional Berhad (TNB), which state your consumption in kilowatt-hours (kWh).
• For Scope 3: Data collection can be complex. It might involve surveying suppliers about their emissions, tracking flight distances for business travel, or estimating emissions from waste based on weight and type.

Data quality is paramount. Use primary data from invoices, meter readings, and expense reports whenever possible. When primary data is unavailable, you may need to use industry averages or estimates, but be sure to document your methodology.

Step 3: Select Emission Factors and Calculate Emissions

An emission factor is a value that converts your activity data into GHG emissions. It represents the quantity of a GHG emitted per unit of activity (e.g., kg CO2e per liter of fuel).

The basic formula is:
GHG Emissions = Activity Data x Emission Factor

• Finding Emission Factors: Credible emission factors are published by various bodies. The Intergovernmental Panel on Climate Change (IPCC) provides default factors. National bodies and programs often provide country-specific factors that are more accurate. For Malaysia, you can refer to factors from utility providers or national reports. For electricity, the Peninsular Malaysia grid emission factor published by the Energy Commission is a key resource.
• Calculating Emissions: Apply the appropriate emission factor to your collected activity data for each source. For example, multiply the total liters of diesel used by your fleet by the emission factor for diesel to calculate Scope 1 emissions from transport. Sum up the emissions from all sources to get your total carbon footprint for each scope. Emissions are typically reported in tonnes of carbon dioxide equivalent (tCO2e), which standardizes the impact of different greenhouse gases.

Step 4: Verify Your Data and Report Your Findings

To ensure credibility, it's best practice to have your GHG inventory verified by an independent third party. Verification provides assurance to stakeholders that your calculations are accurate, complete, and compliant with established standards.

Finally, compile your findings into a GHG report. A good report should include:

• A description of your company and the reporting period.
• The boundaries you have defined.
• Your total emissions, broken down by Scope 1, 2, and 3.
• The methodologies and emission factors used.
• An explanation of any uncertainties or data gaps.

This report can be a standalone document or integrated into your company's annual or sustainability report.

Tools and Methodologies for GHG Accounting

You don't have to start from scratch. A wealth of established standards and tools can guide your GHG accounting process.

The GHG Protocol

The GHG Protocol Corporate Accounting and Reporting Standard is the global gold standard. Developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD), it provides a comprehensive framework for GHG accounting. Adhering to the GHG Protocol ensures your reporting is credible, consistent, and comparable with peers worldwide. It offers detailed guidance on setting boundaries, categorizing emissions, and reporting.

ISO 14064

The ISO 14064 series of standards provides specifications and guidance for organizations on GHG quantification, monitoring, and reporting.

• ISO 14064-1: Specifies principles and requirements for designing, developing, and reporting GHG inventories at the organizational level. It aligns well with the GHG Protocol.
• ISO 14064-2: Focuses on GHG projects specifically designed to reduce emissions or enhance removals.
• ISO 14064-3: Provides guidance for the validation and verification of GHG statements.

Achieving ISO 14064-1 certification can add another layer of credibility to your emissions reporting.

Software and Calculators

A variety of software solutions can simplify the GHG accounting process. These platforms can help you organize data, automate calculations, manage emission factors, and generate reports. Options range from simple spreadsheets and free online calculators for small businesses to sophisticated enterprise-level software for large corporations. These tools can significantly reduce the administrative burden and improve the accuracy of your inventory.

Overcoming Challenges in GHG Accounting

While the benefits are clear, businesses often face hurdles when implementing GHG accounting. Awareness of these challenges can help you prepare effective solutions.

Challenge: Lack of Data or Poor Data Quality

Solution: Start with what you can measure accurately. Focus on Scope 1 and 2 emissions first, as the data is often readily available from utility bills and fuel purchase records. For Scope 3, begin with the categories most relevant to your business and for which you can get reasonable data, such as business travel or waste. Develop a data collection plan and work with different departments (finance, operations, procurement) to establish processes for gathering the necessary information systematically.

Challenge: Limited Internal Expertise

Solution: Building capacity takes time. Start by training a small, dedicated team or appointing a "sustainability champion" within your organization. Provide them with access to resources like the GHG Protocol's online training modules. For complex inventories or your first time reporting, consider hiring an external consultant. A consultant can help you set up your initial inventory, train your team, and ensure you are following best practices from the start.

Challenge: The Complexity of Scope 3

Solution: Scope 3 is challenging for everyone. The key is to prioritize. Use a screening tool or qualitative analysis to identify which of the 15 Scope 3 categories are most significant for your business. For many companies, emissions from "purchased goods and services" and "use of sold products" are the largest contributors. Engage with your key suppliers to start a dialogue about their emissions and encourage them to begin their own carbon footprint measurement. Collaboration across the value chain is essential for tackling Scope 3.
