Did you know that Hong Kong’s green bond market grew by 43.2% in 2024 alone? As businesses worldwide face increasing pressure to adopt sustainable practices, Hong Kong has positioned itself as Asia’s premier hub for ESG-compliant finance. The city offers a powerful combination of tax incentives, grant schemes, and regulatory frameworks that make going green not just environmentally responsible but financially advantageous. Let’s explore how your business can benefit from Hong Kong’s comprehensive ESG tax ecosystem.
Hong Kong’s Strategic ESG and Tax Integration
Hong Kong is strategically positioning itself as Asia-Pacific’s leading center for green and sustainable finance, backed by a comprehensive framework of tax incentives, grant schemes, and regulatory requirements. The HKSAR government has committed to achieving carbon neutrality before 2050, with renewable energy targets of 7.5-10% by 2035 and 15% by 2050. This dual approach combines fiscal incentives with mandatory disclosure requirements, creating a powerful strategy that both encourages ESG-compliant business practices and ensures transparency in environmental reporting.
Qualifying Debt Instruments: Tax Exemptions for Green Bonds
The cornerstone of Hong Kong’s green finance tax policy is the Qualifying Debt Instrument (QDI) scheme, administered by the Inland Revenue Department (IRD). This scheme provides significant tax advantages for green bonds and other sustainable debt instruments, making sustainable financing more cost-effective than conventional options.
Tax Treatment Based on Issuance Date
| Issuance Period | Instrument Type | Maturity Period | Tax Treatment |
|---|---|---|---|
| Before April 1, 2018 | Short-term debt | Less than 3 years | 50% concessionary rate (8.25% effective rate) |
| Before April 1, 2018 | Medium-term debt | 3 to 7 years | 50% concessionary rate (8.25% effective rate) |
| Before April 1, 2018 | Long-term debt | 7 years or more | Full profits tax exemption |
| On or after April 1, 2018 | All QDIs | Any tenor | Full profits tax exemption |
QDI Eligibility Requirements
For green bonds and sustainable debt instruments to qualify for tax exemption, they must meet specific criteria:
- Lodging/Listing Requirement: Instruments must be either lodged with and cleared through the Central Moneymarkets Unit (CMU) operated by the Hong Kong Monetary Authority (HKMA), or listed on the Stock Exchange of Hong Kong Limited (SEHK)
- Qualifying Instruments: Interest income and trading profits from QDIs are exempt from profits tax under Section 14A(1B) of the Inland Revenue Ordinance
- Application Process: Issuers must apply to the IRD for QDI status; the IRD maintains a public list of approved instruments updated quarterly
Green and Sustainable Finance Grant Scheme
Launched in May 2021 and extended to 2027, the Green and Sustainable Finance (GSF) Grant Scheme provides direct financial subsidies to eligible bond issuers and loan borrowers. The scheme was significantly expanded in May 2024 to include transition bonds and loans, reflecting Hong Kong’s commitment to supporting industries in their decarbonization journey.

| Tax Rate | 5% concessionary rate (vs. 16.5% standard profits tax rate) |
| Effective Date | Retroactive application from 2023/24 year of assessment |
| Eligible IP | Patents, copyrighted software, plant variety rights |
| Development Requirement | IP must be self-developed by the taxpayer |
| Nexus Approach | Qualifying R&D expenditure ÷ Total development expenditure = Eligible profit percentage |
| Registration Requirement | Non-Hong Kong patents must obtain local registration by July 5, 2026 |
ESG Application: Green Technology Patents
The patent box regime is particularly valuable for companies developing:
- Renewable energy technologies
- Carbon capture and storage solutions

Carbon Markets and Taxation: Current Status
Unlike many jurisdictions, Hong Kong currently does not impose a carbon tax or operate a mandatory emissions trading system (ETS). However, the city is positioning itself as a regional hub for voluntary carbon trading.
Carbon Trading Infrastructure
- Core Climate Platform: Launched by HKEX in late 2022, this voluntary carbon marketplace offers HKD and RMB settlement for international carbon credit transactions, attracting carbon offset projects from across Asia-Pacific
- Regulatory Framework: Securities and Futures Commission (SFC) published regulatory framework for carbon markets
- Strategic Goal: Position Hong Kong as the carbon trading hub for Asia-Pacific region
Compliance Roadmap for Businesses
For Green Bond Issuers
- Pre-Issuance Planning: Determine if instrument meets QDI criteria for tax exemption, engage recognized external reviewer for green bond verification, prepare documentation aligned with international green bond principles
- Issuance and Listing: Ensure minimum issuance size meets GSF Grant Scheme thresholds, list on SEHK or lodge with CMU for QDI eligibility, apply for GSF Grant Scheme within 3 months of issuance
- Post-Issuance Compliance: File for QDI status with IRD, maintain annual reporting on use of proceeds, conduct post-issuance external verification
For HKEX-Listed Companies
- Immediate Actions (2025): Establish GHG emissions data collection systems for Scope 1 and 2, implement climate governance structures (board oversight, management roles), prepare comply-or-explain disclosures for other climate requirements
- Medium-Term Preparation (2026): LargeCap issuers: Develop Scope 3 emissions measurement capabilities, align reporting with ISSB IFRS S2 requirements, consider obtaining external assurance for climate disclosures
- Long-Term Strategic Alignment (2028+): Prepare for full ISSB Standards implementation (HKFRS S1 & S2), integrate sustainability considerations into overall business strategy, develop transition plans consistent with 2050 carbon neutrality goals
For IP-Driven Green Tech Companies
- Patent Box Optimization: Document all R&D expenditure for nexus ratio calculation, ensure IP development is conducted in-house or track outsourcing ratios, register non-Hong Kong patents locally by July 5, 2026 deadline
- Tax Planning: Separate IP income streams for 5% rate application, ensure proper transfer pricing documentation for intra-group IP transactions, coordinate with FSIE regime for any offshore IP income
