GHG Emissions Calculation and Carbon Accounting


Stop Relying on Spreadsheets. Turn Your Carbon Footprint into Audit-Proof Data and Satisfy Global Procurement Demands.

For mid-market companies and SMEs in Singapore, the rules of business engagement have fundamentally changed. You are no longer just evaluated on quality, cost, and delivery; a fourth pillar has entered the equation: verifiable ESG performance.

Large multinational corporations (MNCs) are under increasing pressure to measure and disclose sustainability and value chain emissions, pushing ESG expectations directly onto their suppliers. If your business relies on manual spreadsheets and rough estimations for its greenhouse gas (GHG) emissions, you are facing a massive operational risk. At ContentFactory, we provide deep technical expertise to calculate your Scope 1, 2, and complex Scope 3 emissions accurately, helping you transition from fragmented data to an automated, audit-ready carbon inventory.

What You Need to Know:

The Challenge:

Calculating emissions, especially Scope 3 (value chain) emissions, is notoriously complex. Relying on inconsistent supplier data and manual spreadsheets creates reporting errors and high audit risks.

The Mandate:

All SGX-listed issuers in Singapore are required to report Scope 1 and Scope 2 GHG emissions from FY2025.

Scope 3 emissions reporting becomes mandatory from FY2026 exclusively for STI constituent listed companies. For all other non-STI listed companies, Scope 3 reporting remains voluntary until further notice under the August 2025 ACRA–SGX RegCo revised roadmap.

External limited assurance for Scope 1 and Scope 2 emissions will become mandatory for all listed issuers from FY2029.

The Procurement Reality:

We have entered a “no data, no deal” environment. Procurement teams are increasingly incorporating ESG and carbon disclosure requirements into supplier onboarding and contract renewal processes.

The Solution:

We develop a comprehensive GHG inventory and leverage digital ESG platforms (like EcoDrisil) to automate calculations, track supplier data, and ensure your numbers can withstand rigorous external audits.

What We Deliver: Accuracy, Automation, and Assurance Readiness

We move your business beyond basic compliance, building a data infrastructure that protects your revenue and satisfies enterprise buyers.

1. Comprehensive GHG Inventory Development (Scope 1, 2 & 3)

We calculate your direct and indirect greenhouse gas emissions using internationally recognized methodologies like the GHG Protocol. We systematically categorize your Scope 1 (direct operations), Scope 2 (purchased electricity), and Scope 3 (value chain) emissions, ensuring alignment with emerging ISSB-aligned disclosure expectations and SGX sustainability reporting requirements.

2. Scope 3 Supply Chain Engagement

Scope 3 is the most difficult metric to track because it requires external data. We help you map your value chain, engage your suppliers, and establish efficient data collection protocols. We implement supplier portals and automated questionnaires to systematically capture this critical information without burdening your procurement team.

3. Digital Data Automation

Manual spreadsheets are a primary cause of reporting inconsistency and audit challenges. We leverage technology partnerships, such as the EcoDrisil platform, to transition your company to centralized data management. We automate complex GHG calculations and build real-time performance dashboards, drastically reducing human error and the time your team spends on manual data entry.

4. Decarbonization Strategy & Target Setting

Measurement is only the first step. Once your baseline is established, we identify emission hotspots within your operations and value chain. We then help your leadership team set credible reduction targets aligned with recognized frameworks and develop a phased decarbonization pathway that prioritizes cost-effective reduction opportunities.

5. Pre-Assurance Readiness

With SGX progressively mandating external limited assurance for Scope 1 and Scope 2 emissions, your data must be auditable. We design clear calculation methodology documentation, establish strict internal controls, and build the verifiable audit trails that third-party assurance providers will require.

The ContentFactory Execution Edge: Pragmatic & Disruption-Free

We understand the fears of the C-Suite. Your operations cannot grind to a halt just to collect sustainability metrics.

Zero Operational Disruption

Designed for the Transformation Champion (COO), our data collection frameworks are integrated seamlessly into your existing workflows. We use automated platforms and API integrations where possible so your team can focus on production targets, not paperwork.

The CFO’s Focus on ROI

We ensure carbon accounting is tied to business value. By accurately measuring energy consumption and resource efficiency, we pinpoint areas for tangible cost savings (such as utility reductions) and risk mitigation, satisfying the Financial Steward’s need for hard numbers.

Audit-Proof Integrity

We do not rely on rough estimates. We build an architecture of strict internal controls, traceable meter readings, and verified supplier documentation, ensuring you confidently prepare for future external limited assurance engagements.

 

Frequently Asked Questions:

Scope 1 emissions are direct GHG emissions from sources your company owns or controls (e.g., fuel consumed by company vehicles or factory equipment). Scope 2 covers indirect emissions from purchased electricity, steam, or cooling consumed by your company. Scope 3 includes all other indirect emissions occurring across your value chain, such as purchased goods and services, logistics, business travel, employee commuting, and waste management.

Scope 3 emissions often represent the largest share of a large corporation’s total footprint, and for STI-listed companies in Singapore, Scope 3 disclosure is already mandatory from FY2026, meaning they must collect value chain emissions data from their suppliers, including SMEs who are not directly regulated. As multinational corporations strengthen their climate disclosure obligations, they increasingly require suppliers to provide verified emissions data to support enterprise-wide reporting and procurement compliance.

Relying on decentralized, manual spreadsheets creates a high risk of human error, inconsistent reporting, and missing audit trails. Automated ESG software improves data accuracy, centralizes reporting, reduces manual effort, and strengthens assurance readiness.

SGX has introduced a phased roadmap for climate-related disclosures aligned with ISSB standards. Scope 1 and Scope 2 emissions reporting is mandatory for all listed issuers from FY2025. Scope 3 reporting starts from FY2026 for STI constituent listed companies only. For all other listed companies, Scope 3 reporting is voluntary until further notice, following the extended timelines confirmed by ACRA and SGX RegCo in August 2025. External limited assurance for Scope 1 and Scope 2 emissions becomes mandatory from FY2029 for all listed issuers.

Carbon accounting is the process of measuring, tracking, and reporting greenhouse gas emissions generated by a business across its operations and value chain. It helps organizations understand environmental impact, identify reduction opportunities, and meet stakeholder or regulatory expectations.

A GHG inventory is a structured record of all greenhouse gas emissions associated with a company’s operations, energy usage, transportation, supply chain, and other activities. It forms the foundation of ESG reporting and climate-related disclosures.

Large enterprises are increasingly required to disclose emissions across their value chains. To comply with these requirements, they need verified emissions data from suppliers, logistics partners, and vendors to calculate Scope 3 emissions accurately.

Many SMEs are not directly mandated under SGX regulations. However, SMEs increasingly face indirect pressure through customer procurement requirements, supply chain audits, export expectations, financing requirements, and enterprise ESG due diligence.

The GHG Protocol is the most widely used global standard for greenhouse gas accounting. Companies may also align disclosures with ISSB, TCFD, GRI, SASB, CDP, or SBTi frameworks depending on business and investor requirements.

Science-based targets are emissions reduction goals aligned with climate science and global decarbonization pathways, including efforts to limit global warming in line with international climate objectives.

Manufacturing, logistics, retail, food production, chemicals, construction, technology, energy, shipping, and export-oriented industries are among the sectors facing increasing emissions disclosure expectations.

Accurate emissions tracking helps organizations identify operational inefficiencies, reduce energy consumption, optimize resource usage, strengthen procurement competitiveness, improve investor confidence, and reduce long-term compliance risks.

 Limited assurance is an independent review conducted by assurance providers to evaluate whether sustainability disclosures and emissions data are materially accurate and prepared according to recognized standards and methodologies.

Depending on operational complexity and data availability, most mid-market organizations can establish an initial GHG inventory within a few months. Scope 3 calculations typically require additional supplier engagement and data collection.

The biggest challenges include incomplete supplier data, inconsistent reporting formats, lack of centralized systems, complex value chains, and difficulties verifying third-party information.

ESG software centralizes sustainability data, automates calculations, improves reporting accuracy, supports audit trails, simplifies supplier engagement, and reduces the operational burden associated with manual data management.
