① Net profit attributable to owners of the Company.
② 2017 and 2018 figures are based on the Accounting and Reporting Requirements for Greenhouse Gas Emissions Part I: Power Generation Enterprises (GB/T 32151.1-2015, effective from June 1, 2016)
issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and Standardization Administration of the People's Republic of China. Carbon dioxide emissions and carbon emission intensity in thermal power generation increased in 2019 for two reasons: (i) China changed the formulas for carbon oxidation rate and carbon content per unit heat value from coal; (ii) increase in heat supply compared with 2018.
③ Third party performed an independent limited assurance of figures marked with "*". The emission rate is calculated based on the data captured in 2019 by the Continuous Emission Monitoring System installed in thermal power plants (pp. 14-15) that are wholly-owned, controlled (as identified by △ ) by China Resources Power Holding Co., Ltd., and in the Luoyang and Yixing power plants (shutdown in Sep and Dec 2019, respectively) and the Zhuhai project (heat-supply generators). See pages 4 to 5 for the assurance report. Emission rates of nitrogen oxides, sulfur dioxide, and particulates in 2015-2019 are calculated based on data captured by the Continuous Emission Monitoring System.
④ Power consumption rate of factories increased in 2019 for two reasons: (i) expanding heat supply business, resulting in a 11.3% increase in heat supply and 3.2 percentage points increase in heat-topower ratio compared with 2018; (ii) commissioning of new projects and equipment including sludge incinerators, energy storage, electric boilers, and electric air compressors.
⑤ Excluding non-cash expenditures and incomes such as impairments and exchange gains and losses.
⑥ Sulfur dioxide emission rate (g/kWh): Sulfur dioxide emission per unit power generation
Nitrogen oxides emission rate (g/kWh): Nitrogen oxides emission per unit power generation
Particulate emission rate (g/kWh): Particulates emission per unit power generation
Emission rate = total emission/total electricity generated
⑦ Installation rate of desulfurization equipment in coal-fired power plants (%): The number of coal-fired power plants with desulfurization equipment to the total number of coal-fired power plants
⑧ CR Power has been strengthening the management of hazardous wastes, including adopting more rigorous collection, statistical, and disposal protocols. This is reflected in the higher amount and density values.
⑨ The data of personal injury and fatality incidents contains CR Power's stakeholders' accidents. See page 51 for the further description.
⑩ Due to the disposal of coal assets in 2018, the number of employees holding coal-related safety certificates has dropped sharply. In 2019, production assurance managers at all levels enrolled in safety management trainings and obtained qualification certificates. CR Power encourages its employees to take the certified safety engineer examination; many have become certified.
CR Power takes ESG management seriously. We take every ESG performance indicator as a means to gauge and improve our management practices, and continuously improve the soundness and rigor of our statistical methodology. To promote the sustainability of our business, each year we review and promote the indicators thusly optimized, and analyze the cause of and develop improvement plans for any deficiencies.
To the Board of Directors of China Resources Power Holdings Company Limited
We have undertaken a limited assurance engagement in respect of the selected sustainability information of China Resources Power Holdings Company Limited (the "Company") listed below and identified with an asterisk (*) on pages 89 to 90 (the "Identified Sustainability Information") in the Company's sustainability report for the year ended 31 December 2019 ("the 2019 Sustainability Report") .
Identified Sustainability Information
The Identified Sustainability Information for the year ended 31 December 2019 is summarised below:
lNitrogen Oxides (NOX) emissions (kt)
lNitrogen Oxides (NOX) emission rate (g/kWh)
lSulphur Dioxide (SO2) emissions (kt)
lSulphur Dioxide (SO2) emission rate (g/kWh)
lParticulates emissions (kt)
lParticulates emission rate (g/kWh)
lInstallation rate of desulfurization device in coal-fired thermal power plants (%)
lInstallation rate of denitrification device in coal-fired thermal power plants (%)
lNatural gas consumption (Million cubic meters)
lDiesel consumption (kt)
lCoal consumption (kt)
lNet generation coal consumption rate (g/kWh)
lPurchased electricity (MWh)
Our assurance was with respect to the year ended 31 December 2019 information only and we have not performed any procedures with respect to earlier periods or any other elements included in the 2019 Sustainability Report and, therefore, do not express any conclusion thereon.
The criteria used by the Company to prepare the Identified Sustainability Information is set out in Note 3 of "Key Performance Index" on pages 89 to 90 of the 2019 Sustainability Report (the "Criteria").
The Company's Responsibility for the Identified Sustainability Information
The Company is responsible for the preparation of the Identified Sustainability Information in accordance with the Criteria. This responsibility includes the design, implementation and maintenance of internal control relevant to the preparation of Identified Sustainability Information that is free from material misstatement, whether due to fraud or error.
The absence of a significant body of established practice on which to draw to evaluate and measure non-financial information allows for different, but acceptable, measures and measurement techniques and can affect comparability between entities.
Our Independence and Quality Control
We have complied with the independence and other ethical requirements of the International Code of Ethics for Professional Accountants issued by the International Ethics Standards Board for Accountants, which is founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour.
Our firm applies International Standard on Quality Control 1 and accordingly maintains a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.
Our responsibility is to express a limited assurance conclusion on the Identified Sustainability Information based on the procedures we have performed and the evidence we have obtained. We conducted our limited assurance engagement in accordance with International Standard on Assurance Engagements 3000 (Revised), Assurance Engagements other than Audits or Reviews of Historical Financial Information issued by the International Auditing and Assurance Standards Board. That standard requires that we plan and perform this engagement to obtain limited assurance about whether the Identified Sustainability Information is free from material misstatement.
A limited assurance engagement involves assessing the suitability in the circumstances of the Company's use of the Criteria as the basis for the preparation of the Identified Sustainability Information, assessing the risks of material misstatement of the Identified Sustainability Information whether due to fraud or error, responding to the assessed risks as necessary in the circumstances, and evaluating the overall presentation of the Identified Sustainability Information. A limited assurance engagement is substantially less in scope than a reasonable assurance engagement in relation to both the risk assessment procedures, including an understanding of internal control, and the procedures performed in response to the assessed risks.
The procedures we performed were based on our professional judgement and included inquiries, observation of processes performed, inspection of documents, analytical procedures, evaluating the appropriateness of quantification methods and reporting policies, and agreeing or reconciling with underlying records.
Given the circumstances of the engagement, in performing the procedures listed above we:
lMade appropriate inquiries of management of the Company and its subsidiaries;
lAssessed the design of critical process and control for collecting and reporting the Identified Sustainability Information;
lUndertook limited analytical procedures over the Identified Sustainability Information;
lRe vie wed relevant supporting information and documents for Identified Sustainability Information provided by management; and
lDid not perform any testing on the Continuous Emission Monitoring System of the Company.
The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for, a reasonable assurance engagement. Consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had we performed a reasonable assurance engagement. Accordingly, we do not express a reasonable assurance opinion about whether the Company's Identified Sustainability Information has been prepared, in all material respects, in accordance with the Criteria.
Limited Assurance Conclusion
Based on the procedures we have performed and the evidence we have obtained, nothing has come to our attention that causes us to believe that the Company's Identified Sustainability Information for the year ended 31 December 2019 is not prepared, in all material respects, in accordance with the Criteria.
Our report has been prepared for and only for the Board of Directors of the Company and for no other purpose. We do not assume responsibility towards or accept liability to any other person for the content of this report.
