Hong Kong's Evolving Tax Incentives for Green Investments: What's New in 2024-2025

As Hong Kong positions itself as a leading green finance hub in Asia, the government has significantly expanded its suite of tax incentives and grant schemes to encourage sustainable investments. From enhanced R&D deductions to carbon credit tax concessions, businesses and investors now have unprecedented opportunities to benefit from green initiatives while contributing to Hong Kong's decarbonisation goals.

Green and Sustainable Finance Grant Scheme: Extended and Expanded

The cornerstone of Hong Kong's green finance incentives is the Green and Sustainable Finance (GSF) Grant Scheme, launched in May 2021. Following its success, the 2024-25 Budget extended the scheme by three years to 2027 and expanded its scope to include transition bonds and loans.

Impressive Track Record

By August 2025, the GSF Grant Scheme had supported over 600 green and sustainable debt instruments worth approximately US$167 billion. This represents a substantial increase from the initial 340 instruments totalling US$100 billion reported earlier in the scheme's operation.

What the Scheme Covers

The GSF Grant Scheme provides subsidies in two categories:

General bond issuance costs: Legal fees, stock exchange listing fees, and related expenses
External review costs: Pre-issuance and post-issuance third-party opinions and verification

For green and sustainable loans, subsidies are limited to external review costs only. The scheme now covers green bonds, sustainable bonds, sustainability-linked bonds, and the newly added transition bonds and loans, providing flexibility for industries transitioning toward decarbonisation.

Digital Bond Grant Scheme: New in 2024

Complementing traditional green finance incentives, the Hong Kong Monetary Authority launched the Digital Bond Grant Scheme (DBGS) in November 2024, marking a significant innovation in sustainable finance technology.

Grant Structure

Half Grant: HK$1.25 million (50% of eligible expenses) for issuances meeting Basic Requirements
Full Grant: HK$2.5 million (50% of eligible expenses) for issuances meeting all Additional Requirements
Duration: Three-year initial period, accepting applications from 28 November 2024

This scheme encourages the use of distributed ledger technology in green bond issuances, positioning Hong Kong at the forefront of digital securities markets.

Enhanced R&D Tax Deductions for Green Technology

Hong Kong's "super tax deduction" for research and development, introduced in the 2018/19 assessment year, provides substantial benefits for companies investing in green technology innovation.

Deduction Rates

Expenditure Type	Amount Range	Deduction Rate
Type A Expenditure	All amounts	100%
Type B Expenditure	First HK$2 million	300%
Type B Expenditure	Amount exceeding HK$2 million	200%

Qualification Requirements

To qualify for the enhanced deduction rates, businesses must meet specific criteria:

R&D activities must be conducted in Hong Kong
Activities can be carried out by the taxpayer or outsourced to designated local research institutions
Only consumables and staff costs directly related to R&D qualify
Expenses must be exclusively and directly attributable to qualifying R&D activities

For companies conducting R&D overseas, a 100% deduction is available, but only if overseas costs do not exceed 20% of total R&D expenditure and the reimbursed amount is HK$2 million or less.

Environmental Protection Equipment: 100% Immediate Deduction

Since the 2018-19 assessment year, Hong Kong has offered accelerated capital allowances for environmental investments, fundamentally changing the tax treatment of green assets.

Eligible Assets

Capital expenditure on the following qualifies for 100% immediate deduction in the year of acquisition:

Environmental protection machinery and installations
Energy-efficient building installations registered under HKEERSB (Hong Kong Energy Efficiency Registration Scheme for Buildings)
Renewable energy devices
Environment-friendly vehicles (hybrid and electric vehicles)

Energy-Efficient Building Installations

To qualify for accelerated deduction, energy-efficient building installations must be registered under the HKEERSB administered by the Electrical and Mechanical Services Department (EMSD). A compliance certificate from EMSD serves as proof of registration.

Important: If the HKEERSB registration application is withdrawn, ceased, or refused within six years, the Inland Revenue Department will raise a profits tax assessment to withdraw the previously granted deduction.

Connection to BEAM Plus Certification

The BEAM Plus Assessment System, administered by the Hong Kong Green Building Council, is connected to the HKEERSB registration scheme. Buildings pursuing BEAM Plus certification can benefit from the accelerated tax deductions for qualifying energy-efficient installations.

Carbon Credits and Emission Derivatives: Proposed Tax Treatment

In November 2024, the Financial Services and Treasury Bureau (FSTB) issued a groundbreaking consultation paper proposing significant enhancements to Hong Kong's preferential tax regimes, with implications for green investments.

Proposed Expansion of Unified Fund Exemption (UFE)

The consultation proposed including carbon credits and emission derivatives as qualifying assets under three key tax regimes:

Unified Fund Exemption (UFE)
Family-Owned Investment Holding Vehicle (FIHV) tax concession
Carried Interest Tax Concession

Scope of Qualifying Assets

The proposed scope includes:

Emission derivatives: Trading systems such as the UK Emissions Trading Registry and the European Union Emissions Trading System
Carbon credits: Credits traded on the Core Climate platform established by Hong Kong Exchanges and Clearing Limited (HKEX)

The consultation closed on 3 January 2025, and the final policies are expected to be shaped by industry feedback received during this period.

Strategic Significance

Hong Kong currently operates a voluntary carbon market through HKEX's Core Climate platform, the only marketplace in Asia-Pacific offering HKD and RMB settlement for international carbon credit transactions. While Hong Kong has no mandatory emissions trading system, carbon tax, or carbon border adjustment mechanism, it aims to develop into a regional carbon trading hub, particularly as China operates the world's largest emissions trading system.

Green Tech Fund: Direct R&D Support

Beyond tax deductions, the Green Tech Fund (GTF) provides direct financial support for green technology research and development projects.

Environment-Friendly Commercial Vehicles

Since April 2008, businesses investing in environmentally friendly commercial vehicles meeting Euro V emission standards receive First Registration Tax (FRT) reductions:

100% reduction for taxis, light buses, non-franchised buses, and special purpose vehicles
50% reduction for goods vehicles (except van-type up to 1.9 tonnes)
30% reduction for van-type goods vehicles up to 1.9 tonnes permitted gross vehicle weight

Qualifying Debt Instrument (QDI) Scheme

Introduced in 1996 and expanded over time, the QDI scheme provides concessionary tax treatment on interest income and trading profits from qualifying debt instruments, including green bonds. This longstanding incentive continues to attract overseas issuers to Hong Kong's debt market.

Broader Green R&D Funding Landscape

Beyond the Green Tech Fund, Hong Kong supports green R&D through multiple channels, with over HK$800 million approved across:

Innovation and Technology Fund
Green Tech Fund
New Energy Transport Fund
Other specialised funding programmes

These funds have supported hundreds of R&D and pilot projects in net-zero electricity generation, energy-saving technologies, green buildings, and sustainable transport solutions.

ESG Regulatory Developments Supporting Green Investment

Hong Kong's green tax incentives operate within an evolving ESG regulatory framework:

ISSB Standards Roadmap (December 2024)

On 10 December 2024, the Hong Kong government issued its roadmap for adopting International Sustainability Standards Board (ISSB) disclosure standards. Large publicly accountable entities will fully adopt ISSB standards by 2028, creating demand for green investments that meet new disclosure requirements.

Mandatory Climate Disclosures

From 1 January 2026, issuers on the Hang Seng Composite LargeCap Index must disclose climate-related risks on a mandatory basis. Hong Kong Exchange plans to consult in 2027 on mandatory sustainability reporting for all listed companies from 1 January 2028.

ESG Code of Conduct

In October 2024, the International Capital Market Association published Hong Kong's voluntary Code of Conduct for ESG Ratings and Data Products Providers, sponsored by the Securities and Futures Commission. This enhances transparency and reliability in ESG markets.

Market Dynamics Driving Green Investment

Hong Kong's green tax incentives respond to strong market demand:

The SFC reported a 35% increase in ESG fund registrations in 2024
91% of Hong Kong consumers are willing to pay up to 7% more for eco-friendly products (2024 Consumer Council survey)
68% of B2B decision-makers prioritise suppliers with clear ESG commitments, up from 52% in 2022 (HKTDC and PwC Hong Kong 2024 report)
