Reporting of greenhouse gas (GHG) emissions is important for companies wishing to monitor their carbon emissions, reduce environmental impacts, cut costs and demonstrate exemplary corporate social responsibility.

With increasing global concern about climate change, consumer demand is shifting towards products and services which are low-carbon and environmentally friendly. In Hong Kong and worldwide, corporate social responsibility is becoming increasingly synonymous with the “triple bottom line” of “People, Planet, Profit”.

By reporting and verifying emissions, companies can benefit Hong Kong as a whole, helping the economy reach the highest standards of information transparency and environmental performance.

Reminder: No translation of submitted information will be provided by this website. It is highly recommended that all descriptive information shall be provided by reporters in both English and Chinese, so that readers of either language can read them.


Part 1 Reporting Entity Information

1.1 Company information

The basic information of your company should be reported. First, input the name of your company and the company stock code as listed on the Hong Kong Stock Exchange.

Input the industry under which your company is classified by the Hang Seng Industry Classification System, plus the specific sector. If your company operates a hotel for example, you should input “Consumer Discretionary – 23” for industry and “Travel & Leisure – 2340” for sector. You may also input any additional information on your reporting, e.g. parent-subsidiary relationship.

1.2 Basis of information reported in this form

If you have conducted greenhouse gas (GHG) emissions reporting for your company, please provide the basis of information reported in this form under Part 1.2. You can also list out the weblinks that can be accessed to your respective reports (e.g. Carbon Audit report, ESG report, Sustainability Report, or any other related reports).

Part 2 Greenhouse Gas (GHG) Emissions

2.1 GHG emissions data

First input the reporting period for which the GHG emissions have been accounted. According to EPD/EMSD guidelines and other equivalent protocols and standards, the customary reporting period is usually one year.

The data you enter is the estimates made or measurements taken of all the different GHG emission sources the company is reporting for. The more activities that are included, the closer the reported GHG emissions approach the actual emissions. Data should be categorised according to the “Scopes” of emissions as defined by the GHG Protocol, as follows:

  • Scope 1: Direct emissions from sources which are owned and controlled by the company, including fossil fuels burned on site such as town gas, company-owned and company-leased vehicles, GHG release from leaking systems such as air-conditioning and refrigeration systems; and removal of GHG such as tree planting.

  • Scope 2: Energy indirect emissions from generation and transmission energy purchased by the company, i.e. electricity and town gas.

  • Scope 3: Other indirect emissions from sources not owned or not directly controlled by the company but related to the company’s operations. These include emissions from fresh water purchased, corresponding sewage treatment, waste disposal, and any outsourced activities. 

When filling out the quantity of emissions calculated for each scope, be careful to report in the correct units - tonnes CO2-e. This represents tonnes of carbon dioxide equivalent, the most common reference unit for GHG emissions reporting. The reported GHG emission in total will equal the sum of all Scope 1, 2 and 3 emissions.

2.2 Company related information

Enter company information of employees, gross floor area (m2) and revenue (HK$ million) where applicable, as accurately as possible. If possible, the information given should be relevant only to the company operations covered by greenhouse gas emissions reporting.

2.3 Geographical coverage of reported GHG emission data

The geographical coverage of the company will depend on the physical boundary chosen by the company, prior to GHG accounting. Some companies may prefer to report exclusively on emissions from their operations in Hong Kong, whereas as others may be reporting for all international branches and subsidiaries. Please specify details of the branches reported for in Hong Kong and abroad, as well as subsidiaries. Space is also provided for any additional information on the physical boundary, if applicable, e.g. only certain part of the company covered by the reported GHG emission data.

Part 3 GHG Emission Reduction Measures, Future Initiatives and Targets

3.1 GHG emission reduction measures implemented during the Reporting Period

Emission reduction measures are any activities which lead to less greenhouse gas emissions, such as planting of trees. These can be reported in Table 3.1.

Reductions may be reported quantitatively, accounting for accurate numeric amounts of GHG reductions. Please input the estimated quantity of reductions in tonnes CO2-e for quantitative emissions reductions. Reductions may also be qualitative, without accurate numeric values but still positively reducing emissions. Please also report the company’s qualitative reduction measures, even if the company does not have precise data for the quantity of reductions.

3.2 GHG emission reduction measures for future initiatives and targets

Besides reporting GHG emissions and reductions in the company’s report, for the purpose of continuous development and improvement it is equally important to set new targets for decreasing the company’s carbon footprint. Please enter any future initiatives the company intends to pursue in Table 3.2, as well as the targeted quantitative/qualitative reductions.

If there is insufficient space for reporting all reduction measures, please add additional points on a separate sheet.

Part 4 Renewable Energy

4.1 Feed-in Tariff (FiT) Scheme

The Feed-in Tariff (FiT) Scheme ( is an important initiative to promote the development of renewable energy (RE) under the current Scheme of Control Agreements (SCAs), which were signed between the Government and the respective two power companies in April 2017. Under the scheme, people who install solar photovoltaic (PV) or wind systems at their premises can sell the RE they generate to the power companies at a rate higher than the normal electricity tariff rate to help recover the costs of investment in the RE systems and generation. If your company has joined the FiT scheme, please provide the type of RE technology (i.e. solar or wind) that is used to participate in the FiT scheme, as well as the generation capacity of the installed RE system.

4.2 Renewable Energy Certificates

The Renewable Energy Certificates (RE Certificates) Scheme ( is another important RE initiative introduced under the current Scheme of Control Agreements (SCAs). Under this scheme, RE Certificates are sold by the power companies for units of electricity from local RE sources such that buyers can claim their operation or activities are carbon-free. If your company has purchased RE Certificates, please indicate whether they were purchased from The Hongkong Electric Co., Ltd or CLP Power Hong Kong Ltd, and the amount of electricity purchased.

Part 5 Verification

Independent verification of GHG emissions can facilitate management in forming a better understanding of the carbon footprint of the company’s operations and identifying areas for improvement. Verification provides credibility and professional quality assurance when disclosing carbon footprint information, and enhances corporate image in terms of transparency and accountability.

In December 2012, the Hong Kong Accreditation Service (HKAS) introduced accreditation service for ISO 14064 GHG validation and verification for validation/verification bodies’ voluntary application. Accredited validation/verification bodies’ technical competence is rigorously assessed by HKAS, so that the reliability of their results can be assured. Relevant HKAS-accredited validation/verification bodies, once available, will be announced at HKAS’s website at: (Open new window).

If your GHG report has been verified, please check “Yes” and enter the name of the verification body, the standards which the body adopts and the date on which the verification was conducted.

Submission and Consent for Disclosure

The CEO or his/her delegated staff(s) should state his/her consent, on behalf of the listed company, to disclose the information by filling in, signing, and submitting the Consent Form together with the Reporting Form, either by hardcopy or through online submission. Our Helpdesk will contact you if further clarification is needed.
