Frequently Asked Questions

Q: Who is accredited to conduct carbon tax verification in Singapore?

Only independent verification companies accredited by the National Environment Agency (NEA) can perform official GHG verification under the Carbon Pricing Act. SG CO2 Pte Ltd is an officially accredited auditor for Non-Complex sectors.

Q: What is the annual deadline for submitting the verified Emissions Report to NEA?

Taxable facilities must submit their verified Emissions Report alongside the accredited verifier's Verification Report to NEA by 30 June of the year following the reporting period.

Q: What scope of emissions is verified during a carbon tax audit?

The third-party verification process focuses specifically on reckonable greenhouse gas (GHG) emissions in accordance with the facility's approved Monitoring Plan and NEA guidelines.

Q: What is the Carbon Pricing Act (CPA) 2018?

The CPA is Singapore's statutory framework enforcing a mandatory Measurement, Reporting, and Verification (MRV) regime combined with a carbon tax. It prices greenhouse gas emissions to incentivize industrial decarbonization across major emitters.

Q: What is the statutory carbon tax rate roadmap?

The tax rate is legislated on a progressive trajectory applied to each metric ton of reckonable direct emissions (tCO2e):
  • 2019 – 2023: S$5/tCO2e
  • 2024 – 2025: S$25/tCO2e
  • 2026 – 2027: S$45/tCO2e
  • 2028 – 2029: Indicative stepped trajectory (S$50 to S$65/tCO2e)
  • 2030 Target: S$50 to S$80/tCO2e

Q: What direct emissions are classified as "Reckonable" versus "Non-Reckonable"?

  • Reckonable (Taxable): Stationary fuel combustion (turbines, boilers, flares), industrial chemical processes (fluorinated gases in electronics, catalytic cracking), and direct waste incineration.
  • Non-Reckonable / Excluded: Mobile vehicle fleets and forklifts (regulated via fuel excise duties), combustion of pure biomass/biofuels, localized fire-suppression testing, and electrical switchgear maintenance.

Q: Who is legally designated as the "Registered Person"?

The corporate entity that exercises operational control over a business facility—defined as holding the legal and practical authority to implement operating, environmental, and health and safety policies at the physical site.

Q: Who within the organization is accountable for CPA compliance?

Under CPA regulations, every registered facility must officially appoint:
  • Designated Representative (DR):): A C-suite executive or director who holds legal liability for signing off on emissions reports, monitoring plans, and statutory declarations.
  • GHG Manager: A designated technical lead responsible for continuous fuel/process data capture, equipment calibration logs, quality assurance, and verification liaison.

Q: Which industry sectors are directly subject to the CPA?

The CPA directly regulates facilities operating across three prescribed high-emitting industry sectors:
  1. Manufacturing and Processing: Refining, petrochemicals, electronics/semiconductors, specialty chemicals, and pharmaceuticals.
  2. Utilities and Power Generation: Thermal power generation plants, steam, compressed air, and district cooling providers.
  3. Waste and Water Infrastructure:Municipal solid waste incineration facilities and large industrial water treatment complexes.

Q: Which sectors are exempt from direct CPA obligations (e.g., Commercial Real Estate, REITs)?

  • Direct Exemption: Commercial office towers, shopping centers, logistics warehouses, data centers, and corporate office spaces are not directly regulated or taxed under the CPA.
  • Reason:Commercial facilities generate emissions primarily through purchased grid electricity (Scope 2). The CPA applies exclusively to direct Scope 1 emissions, which are taxed upstream at power generation stations.
  • Corporate Disclosure Nuance: While exempt from direct CPA filing, listed REITs and large commercial enterprises remain subject to mandatory SGX/ACRA climate reporting standards (ISSB/TCFD), requiring disclosure of both Scope 1 and Scope 2 operational emissions.

Q: When is the statutory deadlines & critical timelines

  • By 31 March (Year Y+1): Submission deadline for unverified emissions reports from Reportable Facilities (≥2,000 tCO2e)
  • By 30 June (Year Y+1):Mandatory submission of audited and verified emissions reports and Verification Statements for Taxable Facilities (≥25,000 tCO2e) via the EDMA portal.
  • By 31 August (Year Y+1):Submission of Evidence of Retirement (EOR) for entities utilizing International Carbon Credits (ICCs) to offset tax liability.
  • By 30 September(Year Y+1):Final settlement date for purchasing and surrendering fixed-price carbon credits following receipt of the Notice of Assessment from the NEA.

Q: How does independent verification operate under ISO 14064-3?

Accredited verification bodies (VBs) must execute an audit strategy built around four core phases:
  1. Risk Evaluation: Assess Inherent Risk (complexity of chemical reactions or calculation formulas) and Control Risk (reliability of flow meters and internal spreadsheets).
  2. Field Execution: On-site inspection of measurement instruments, review of ISO/IEC 17025 calibration certificates, and substantive testing of fuel purchase ledgers.
  3. Independent Technical Review: A qualified technical reviewer—independent of the field audit team—evaluates the working papers and findings before assurance is finalized.
  4. Assurance Threshold: Verifiers certify data to a Reasonable Level of Assurance, ensuring cumulative misstatements or omissions remain strictly under the 5% materiality limit.

Q: How can taxable facilities mitigate their net carbon tax bill?

  • Transitional Allowances Scheme:: Facilities operating in Emissions-Intensive Trade-Exposed (EITE) sectors receive benchmark-based transition allowances covering a portion of their emissions, shielding export competitiveness against jurisdictions without carbon pricing.
  • International Carbon Credits (ICCs):): Facilities may surrender eligible Article 6-compliant international credits to offset up to 5% of their annual taxable emissions.
  • Energy Efficiency Upgrades:: Direct abatement through heat recovery, electrification, and process gas scrubbers reduces physical reckonable emissions at the source.
