Xie Zhanhuan: Strengthen Regional Energy Cooperation to Promote Hong Kong's Transition to Net-Zero Generation

On June 24th, the Secretary for the Environment in Hong Kong, Wong Kam-sing, stated in response to questions from lawmakers that the Hong Kong government is gradually promoting energy structure transformation based on four energy policy objectives: safety, reliability, reasonable prices, and environmental performance. This is to reduce carbon emissions and achieve the mid- and long-term goal of "net zero emissions" set out in the "Hong Kong Climate Action 2050 Blueprint." This goal aims to increase the share of zero-carbon energy to around 60-70% by 2035, and achieve "net zero emissions" and carbon neutrality by 2050. Wong Kam-sing pointed out that by gradually replacing coal-fired power generation with natural gas and increasing nuclear input, Hong Kong peaked in carbon emissions in 2014, with emissions reduced by over a quarter by 2024. Currently, coal accounts for less than 20% of Hong Kong's overall electricity fuel mix, zero-carbon energy (including nuclear and renewable energy) accounts for about 28%, and natural gas accounts for over half. In terms of strengthening regional cooperation to promote energy structure transformation, Wong Kam-sing stated that Hong Kong's hilly terrain and limited land area have restricted the development of nuclear, hydro, CECEP Solar Energy, and wind energy. Despite this, Hong Kong has increased nuclear energy's share in the fuel mix to nearly 30% through energy imports. Increasing the input of zero-carbon energy helps to stabilize electricity prices, improve the resilience and stability of the power system, and promote sustainable high-quality development across industries. Regarding cross-border power transmission infrastructure, Wong Kam-sing revealed that China Southern Power Grid Company Limited has established a clean energy transmission system connecting Daya Bay Nuclear Power Station to the southern power grid of China to import zero-carbon electricity. With the strengthening of this system by March 2026, Hong Kong will gradually increase the share of zero-carbon energy in its fuel mix to around 35%. The government is also making forward-looking arrangements to deepen regional energy cooperation and actively cooperate with the country to accelerate the construction of a new energy system to achieve the long-term goals of "net zero emissions" and carbon neutrality. This includes coordinating with national policies to import diverse zero-carbon energy sources, continue planning power supply infrastructure, and establish cooperation mechanisms with mainland entities. Wong Kam-sing noted that the country has made significant progress in renewable energy supply certification and carbon emission accounting. The issuance of Chinese Green Electricity Certificates (Green Certificates) by the National Energy Administration is effective proof of renewable energy attributes (such as CECEP Solar Energy, hydro, wind, etc.). Each Green Certificate unit corresponds to 1000 kWh of renewable energy and is valid for two years. To ensure that the Green Certificates are not double-counted, the National Energy Administration synchronizes updates with various trading platforms through the National Green Certificate issuance and trading system to record and store information on issuance, trading, and verification of Green Certificates. As for carbon emission accounting, it is a mechanism for uniform calculation of greenhouse gas emissions. In the "Outline of the 15th Five-Year Plan," the country also set out processes to develop rules and standards for calculating product carbon footprints and promote international recognition of carbon footprint rules. Hong Kong is actively exploring measures to advance the development of Green Certificates in the Guangdong-Hong Kong-Macao Greater Bay Area. Looking ahead, the government will explore ways to assist national energy-related enterprises and the Green Certificate market in expanding their application scenarios in the international market, promoting green energy transformation from various angles. Regarding facilitating the entry of mainland low-carbon energy and hydrogen energy companies into Hong Kong, Wong Kam-sing stated that in 2022, the government established a cross-departmental working group on hydrogen energy to coordinate the preparation for local hydrogen fuel applications and promote the use of hydrogen energy locally. The working group reviews applications for hydrogen fuel pilot projects and provides advice on safety and planning, facilitating various hydrogen energy companies to carry out hydrogen energy trials. To date, the working group has reviewed and agreed in principle to 40 trial project applications, many of which involve the use of mainland products and technology. Additionally, in December 2024, the Electrical and Mechanical Services Department signed a "Quality and Safety Management Cooperation Arrangement" with the State Administration for Market Regulation, officially establishing a cooperation framework covering five areas, including standard metrology and conformity assessment, special equipment related to hydrogen energy, mechanical devices, household products, and energy efficiency labeling. Substantial progress has been made, including facilitating the implementation of national standards in Hong Kong to lay the foundation for technical specifications for mainland hydrogen energy and related products to be recognized in Hong Kong, using hydrogen energy as a pilot for deepening cooperation to jointly develop national and international standards, promoting the application of mainland-developed hydrogen energy equipment safety monitoring platforms in Hong Kong to enhance the safety supervision of hydrogen energy facilities in both regions, researching the mutual recognition and approval of pressure vessel data between the two regions to simplify cross-border approval processes under controllable risks. Wong Kam-sing pointed out that the State Administration for Market Regulation stated at the International Hydrogen Energy Development Forum held in Hong Kong in May 2026 that the next stage will further deepen cooperation with Hong Kong, moving from "project pilots" to "systematic co-construction." The government will continue to deepen cooperation with the mainland in the field of low-carbon energy and hydrogen energy, leverage its unique advantages in connecting internally and externally, and provide financing support and international standard docking services for related enterprises to "go global" with their technology and products.
