Regulatory and Technological Initiatives
In response to Hong Kong’s growing climate challenges, the Government launched the Hong Kong’s Climate Action Plan 2050, outlining goals under the following themes.
Zero-carbon
Emissions
Liveable City
Sustainable
Development
The EMSD actively supports this vision through its Regulatory and Trading Services, by promoting innovative technologies, advancing energy efficiency, and adopting sustainable workplace practices, aligned with key government initiatives and renewable energy goals.

Regulations and Guidelines for Sustainable Buildings |

|
We regularly review legislation and policies to promote responsible energy use, with the Buildings Energy Efficiency Ordinance serving as a cornerstone. In 2024, the EMSD updated the Codes of Practice for Energy Efficiency of Building Services Installation and Building Energy Audit, raising standards by over 20% compared to 2015. These updates are projected to save 5.4 billion kWh annually by 2035.

Efficient Cooling:
- The EMSD promotes water-cooled air-conditioning systems and released guidelines relating to the Fresh Water Cooling Tower Scheme, Code of Practice, and Guidebook, which were implemented in 2024.
- The EMSD developed the ChillStream® AI Chiller Plant Optimisation System, which uses real-time data and artificial intelligence (AI) algorithm to improve efficiency, achieving 3%-5% energy savings compared to traditional rule-based controllers.
- The EMSD supports large-scale systems like the District Cooling System and Fresh Water Cooling Towers.
- The EMSD promotes renewable energy through the issuance of the Technical Guidelines on Grid Connection of Renewable Energy Power Systems and the Guidance Notes for Solar Photovoltaic System Installation, the publication of resources (such as Hong Kong Renewable Energy Net and Hong Kong Energy Efficiency Net), and the development of a dedicated Feed-in Tariff hotline.
