About this report

Our goal is to be the leading responsible energy provider in the Asia-Pacific region, from one generation to the next. This report discusses in detail how we create value for our stakeholders over the long term.

Welcome to our 2017 report


Under our Value Framework, CLP is committed to communicating and reporting the economic, social and environmental impact of our business to our stakeholders on a regular basis. To fulfill this commitment, the advances in communications technology has led to the need for us to actively engage and listen to our stakeholders through an increasing number of channels that suit their needs and preference. This year we have moved our full Sustainability Report online, allowing us to enhance signposting, draw reference from different sources, show key ideas visually, and to interact with readers more easily.

We hope you will like these changes and welcome your feedback through the online survey or email. As a token of our appreciation, each stakeholder who sends us feedback on or before 30 June 2018 will receive a corporate souvenir from us (subject to availability).

Reporting period and scope


This report covers CLP Group’s sustainability performance for the calendar year ending 31 December 2017. It includes discussions on the “material” topics and “most material” topics identified through our materiality assessment for our relevant company boundaries. It is published at the same time as our Integrated Annual Report. Our previous report was published in March 2017.


For 2016 to 2017, there were no material restatements of the quantitative Key Performance Indicators. Changes to our reporting scopes in 2017 are:

  • Environmental scope: addition of the Fangchenggang II, Laizhou I and Sandu I Power Stations, as they completed their first full calendar year of operation under CLP ownership in 2017. Cathedral Rocks Wind Farm was removed as we transferred the asset management to the asset joint owner as of 1 July 2017, and therefore it did not fulfil the “full calendar year of operation” requirement.
  • Safety scope: Cathedral Rocks is included in the safety scope until 30 June 2017 when the asset management was transferred to the asset joint owner.

Below is the definition of the company boundary for each of the main categories of data included in this Report. Please refer to our 2017 Annual Report for more details on the entities included in our consolidated financial statements.


Includes all people employed by CLP entities or their subsidiaries. It does not include non-CLP employees in our Joint Ventures, Joint Operations or Associates.


Selected financial figures are extracted from our Annual Report and include the financial statements of CLP Holdings Limited and its subsidiaries as well as the Group’s interests in joint ventures and associates in accordance with Hong Kong Financial Reporting Standards (HKFRS) issued by the Hong Kong Institute of Certified Public Accountants (HKICPA). For a detailed description of the financial reporting scope, please refer to the Significant Accounting Policies – Consolidation on pages 201 and 202 of our 2017 Annual Report.


Includes all people employed by CLP entities or their subsidiaries (excluding part time staff unless otherwise specified). It does not include employees of our joint ventures, joint operations, associates or contractors.


Includes all entities which hold power assets, transmission and distribution infrastructure, fuel storage facilities or regional office areas:

  • That are wholly owned or majority owned by CLP; or
  • That are under CLP’s operational control, defined as full authority to implement CLP’s operating policies; and
  • That are under construction or in operation.
  • Resource Use
  • GHG & Air Emissions
  • Environmental Compliance

Includes all entities which hold power assets, transmission and distribution infrastructure or fuel storage facilities and satisfy all the following criteria:

  • That pose material impact to the environment;
  • That are under CLP’s operational control, defined as full authority to implement CLP’s operating policies; and
  • That have been operating for a full calendar year.

100% of the performance data for in scope entities is reported without adjustment of the data to reflect our equity share, unless otherwise stated.


Includes all entities which hold power generation assets.

  • Entities are included on an equity ownership basis, meaning the definition of operational control is not considered, only whether CLP holds an equity share; and
  • The scope includes all entities that were in operation at some point during the reporting year, meaning assets which were acquired during the reporting year are included despite not having been in operation for a full calendar year under CLP ownership.

Performance data is consolidated on an equity basis – i.e. if CLP holds a fraction of the total entity, performance is consolidated on a pro rata basis in accordance with CLP's equity holding.

Some statistical data derived from our overseas operations may not be strictly comparable because local and / or regulatory definitions may vary.


Includes all power generation assets involved with the delivery of electricity to CLP Power Hong Kong customers, and:

  • The total annual CO2 and CO2e emissions are from CAPCO assets in Hong Kong only (as nuclear power does not result in significant carbon emissions); and
  • The GWh is from our Total Electricity Sales for CLPP HK and includes generation from Daya Bay Nuclear Power Station.

Reporting frameworks and content indices

We reference different reporting guidelines and frameworks to ensure our reporting is comprehensive and aligns with international best practices.

Global Reporting Initiative (GRI)
  • The GRI is an international independent organisation which provides the world’s most widely used standards on sustainability reporting.
  • CLP has been reporting with reference to the GRI since 2007, and has adopted the GRI Standards for the second year since it was launched in 2016.
  • This report has been prepared in accordance with GRI Standards: Core option. It also reports on the GRI G4 Electric Utilities Sector Disclosures, and has been checked by GRI on materiality disclosure.

International Integrated Reporting Council (IIRC)
  • The IIRC is a global coalition that created the International Framework which has become the widely used guideline for integrated reporting.
  • CLP’s Annual Report has been reporting with reference to this guideline since 2011. Moving towards a more integrated reporting approach, this report continues to makes reference to the Framework, particularly on the concept of the six capitals.
Hong Kong Stock Exchange Environmental, Social and Governance (ESG) Reporting Guide
  • Companies listed on the Hong Kong Stock Exchange (HKEx) are now required to meet the “General Disclosure” and Key Performance Indicators (KPIs) in the “Environmental” Subject Area, in a “comply or explain” manner.
  • As a Hong Kong listed company, CLP first began reporting according to the ESG Guide in 2012. This report satisfies the “comply or explain” provisions as well as “recommended disclosures” of the Hong Kong Stock Exchange Environmental, Social and Governance (ESG) Reporting Guide (ESG Guide).

Greenhouse Gas Emissions
  • CLP’s greenhouse gas (GHG) emissions inventory covers the six originally specified gases in accordance with the Kyoto Protocol. We have also considered the seventh one added under the Kyoto Protocol, namely nitrogen trifluoride (NF3), but have deemed it immaterial to our operations.
  • Our GHG emissions are reported with reference to: The World Resources Institute (WRI) / World Business Council for Sustainable Development (WBCSD) GHG Protocol, the Intergovernmental Panel on Climate Change’s Guidelines for National Greenhouse Gas Inventories 2006 and international standard ISO 14064.
  • To facilitate implementation, in 2007, we developed the first version of our Group-wide GHG reporting guideline with reference to the aforementioned guidelines. The reporting guideline is regularly reviewed in accordance with CLP practice at least every three years.
Financial Data
  • All financial data in this report is in alignment with the figures published in the audited financial statements as published in our Annual Report. The financial statements are prepared in accordance with Hong Kong Financial Reporting Standards (HKFRS) issued by the Hong Kong Institute of Certified Public Accountants (HKICPA) and the Hong Kong Companies Ordinance.

Materiality for 2017 and stakeholder concerns


The content of this report was determined using our Boundary Scoping and Materiality Identification (BSMI) methodology. The most material topics were identified by our internal and external stakeholders, through their concerns or interests collected during the year from existing engagement channels embedded in our daily operations. The reporting boundary for each topic was defined in terms of including the most relevant material business entities. This year, we piloted additional channels to gauge external views – we commissioned an online stakeholder survey and a technology-driven data analytics report. The results indicated that our internal assessment results seemed broadly aligned with the external views.


Our stakeholders’ concerns or interests about our business vary depending on the location and context and therefore require different actions or responses. The main topics that arose during the year in our various regions, as well as the actions we undertook to address them, are summarised in the following table by stakeholder group.
