The Environment

Hong Kong cooperates internationally on climate action. It is a member of the C40 Cities Climate Leadership Group and sits on the group's Steering Committee.

The EPD provides nine guidebooks, covering different types of premises, for carbon audits in the public and private sectors. Bureaus and departments conduct carbon audits on major government buildings and publish the results. The EPD operates a Carbon Footprint Repository to encourage regular carbon auditing in the private sector. More than 80 listed companies share their carbon management experiences and practices on the repository's website. The government also works with Hong Kong Exchanges and Clearing Limited to promote carbon audits among listed companies.

Energy

Electricity

The Hongkong Electric Company Limited (HK Electric) supplies electricity to Hong Kong Island and the neighbouring islands of Ap Lei Chau and Lamma. CLP Power Hong Kong Limited (CLP Power) supplies Kowloon and the New Territories, including Lantau and several other outlying islands. The electricity supply to consumers is 50 hertz alternating current, while the voltage is 220 volts single-phase and 380 volts three-phase.

Both power companies are investor-owned. The government monitors them through mutually agreed Scheme of Control Agreements, with the current ones signed in 2017. These require the companies to seek the government's approval for certain aspects of their development plans, including projected basic tariff levels, to ensure the continued supply of reliable, safe and efficient electricity at reasonable prices. The agreements do not give the companies any exclusive rights to supply electricity. They are not franchises, nor do they define a supply area for either company or exclude newcomers to the market. The companies receive a return on their average net fixed assets at the permitted rate of return specified in the agreements.

HK Electric has a total installed capacity of 3,637 megawatts at its Lamma Power Station. CLP Power receives its electricity supply from the Castle Peak Power Company Limited's power stations at Black Point (3,175MW), Castle Peak (4,108MW) and Penny's Bay (300MW).

Each company owns its respective transmission and distribution systems. The two transmission systems are connected by a cross-harbour link, which provides emergency backup and some sharing of generating capacity reserves between the two systems. The link has a total capacity of 720 megavoltamperes.

CLP Power's transmission system is also connected to the Guangdong electricity network which allows electricity exports and imports to and from the province. The company imports about 70 per cent of the power generated by the Daya Bay nuclear power station, which has two 984MW pressurised water reactors. In addition, from 2014 to 2023 it imports on a temporary basis another 10 per cent of Daya Bay's electricity.
