Hong Kong’s Integrated Approach to ESG and Tax Policy
Hong Kong is strategically positioning itself as a preeminent center for green and sustainable finance in the Asia-Pacific region, underpinned by a comprehensive framework of tax incentives, grant schemes, and regulatory requirements. The Hong Kong Special Administrative Region (HKSAR) government has committed to achieving carbon neutrality before 2050, with renewable energy targets of 7.5-10% by 2035 and 15% by 2050.
The city’s approach combines fiscal incentives with mandatory disclosure requirements, creating a dual-pronged strategy that both encourages ESG-compliant business practices and ensures transparency in environmental reporting. Hong Kong has become one of the first jurisdictions globally to align its climate reporting requirements with the International Sustainability Standards Board (ISSB) standards, effective from January 1, 2025.
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.
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 |

Patent Box Tax Regime: Innovation Meets Sustainability
The Inland Revenue (Amendment) (Tax Concessions for Intellectual Property Income) Ordinance 2024, enacted on July 5, 2024, introduces a preferential tax rate for intellectual property income, including green technology patents. This regime complements ESG initiatives by incentivizing innovation in sustainable technologies.
Key Features of the Patent Box Regime
| Feature | Details |
|---|---|
| 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

ISSB Standards Alignment
Hong Kong is among the world’s first exchanges to enhance climate-related disclosure requirements based on IFRS S2 (Climate-related Disclosures). The Hong Kong Financial Reporting Standards (HKFRS) S1 and S2, fully aligned with IFRS S1 and S2, will come into effect on August 1, 2025.
Four Pillars of Climate Disclosure:
- Governance: Board oversight and management’s role in climate-related risks and opportunities
- Strategy: Climate-related risks and opportunities affecting business model, strategy, and financial planning
- Risk Management: Processes for identifying, assessing, and managing climate-related risks
- Metrics and Targets: Metrics used to assess climate-related risks/opportunities, including GHG emissions (Scopes 1, 2, and 3)
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
- The only platform in the region offering dual-currency settlement
- Attracts 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
Existing Carbon-Related Levies
| Levy Type | Description | Tax Treatment |
|---|---|---|
| Hydrocarbon Oil Duties | Form of carbon taxation on imported coal and natural gas | Standard excise duties apply |
| Progressive Electricity Tariffs | Higher rates for increased consumption | Not a direct tax; utility pricing mechanism |
| Carbon Credits (voluntary) | Traded on HKEX Core Climate platform | No specific tax treatment; general profits tax applies to trading profits |
Policy Outlook: As of 2024-2025, Hong Kong has not announced plans to implement a mandatory carbon tax, primarily due to concerns about energy cost stability. The government’s focus remains on developing voluntary carbon markets and supporting the decarbonization goals of Greater Bay Area and Belt and Road Initiative participants.
