MESSAGE FROM THE CHAIRMAN 07 We achieved steady and quality-based business growth by consolidating growth momentum with further innovation and deeper reform. Innovation within technology, management and the business model is the fundamental path to address global energy challenges and realize an energy revolution. In this regard, PetroChina focuses on capacity building and promotes organizational and mechanism reforms related to technical innovation to stimulate research institutions and talents. In 2019, PetroChina achieved good performance in technical innovation, contributing effective solutions to issues, such as equal access to energy, response to climate change and enhancement of energy efficiency. Technical advancements boosted increases in reserves and production, as well as a series of major discoveries in risk exploration, including the 3 billion-ton Qingcheng oilfield, and two trillion-m gas regions (i.e. shale gas in the Sichuan Basin and Bozi-Dabei in the Tarim Basin). Innovative theories and new technologies/products were developed, and breakthroughs were made in some core technologies. PetroChina won the First Prize of the National Science and Technology Progress Award for the 100-million-tons production capacity project and the efficient development of carbonate reservoirs in the Middle East. We increased the use of information technology across the industry chain by promoting the formation of digital oilfields, smart refineries, smart pipelines, smart gas stations and IoT, enabling the integration of automatic data collection, remote monitoring and production/business decision-making and enhancement of the efficiency and the reliability of business operations. We further consolidated the foundation for sustainable development through improving compliance management and corporate governance. PetroChina has continued to improve its management mechanism for sustainable development, integrating this concept into the whole value chain for effective control of environmental, social and governance risks. The Company has made increased efforts to improve corporate governance and its internal control system, through compliance management focused on system optimization and responsibility implementation, together with staff training in compliance education to ensure effective control of compliance-related risks. Our internal th control and risk management system was found to have zero defects in external auditing for the 14 consecutive year. PetroChina enhanced supplier access and process monitoring to control ESG risks in the supply chain, and further improved communication and engagement with stakeholders to make our business operations more transparent. The Company was honored with awards such as the Most Honored Oil & Gas Company in Asia, and the Best ESG/SRI Indicators, further adding to PetroChina’s brand value. We have worked on openness and cooperation, to build a community of shared interests in the international oil and gas sector, and witnessed expansion of international cooperation. PetroChina is committed to being a good corporate citizen, a preferred partner of the industry, and to addressing the major changes in the energy sector together with its peers. Its aim is to establish a shared-interest community featuring openness and a win-win cooperation. In 2019, PetroChina hosted important international exchange activities including the Belt and Road Roundtable for Oil & Gas Cooperation, the Sino-Russian Energy Business Forum, and the International Cooperation Forum on the sidelines of the China International Import Expo, and the memorandum on expanding cooperation in the oil and gas field of Kazakhstan and the extension contract of Block 5 in Oman were successfully signed, which represents the continuously expansion of cooperation scale and areas in the oil and gas field. Through corporate social responsibility, we secured equitable and inclusive development. PetroChina has undertaken projects for people’s well-being, and increased employees’ personal benefits by linking their pay to the performance of the Company, thus ensuring the employees enjoyed greater gains, enthusiasm and confidence. We managed to expand up-, mid- and downstream business partnerships with local investors to drive the economic and social development of local areas. PetroChina also leveraged its industrial, technical and human resources for targeted poverty alleviation to support the government’s initiative. In 2019, we implemented nearly 70 targeted alleviation projects, and allocated 73% more funds than in 2018, helping to lift eight of the 10 targeted counties out of poverty. The localization strategy of the Company in overseas operations secured an over 90% local employment rate, among which many took up key technical or management posts. PetroChina paid taxes according to local laws, totaling RMB 42.9 billion overseas. Meanwhile, the Company continued to implement a series of projects to support local communities. PetroChina was honored with the Responsible Enterprise 2019 award for its outstanding social contributions. In the year to come, given the complex situation, with accelerating energy transition and the profound adjustment of the energy supply- demand pattern, PetroChina will have to shoulder greater responsibilities and face more challenges as well as more opportunities. Nevertheless, we will continue to implement the strategy with respect to resources, the market, internationalization and innovation and the goal of building a top-class international energy company. While focusing on efficiency and profit and maintaining quality-based development, we will also seize the opportunities for the petroleum industry’s low-carbon transformation, accelerate the research and layout of new energy business and contribute to the UN Sustainable Development Goals 2030, creating and sharing a bright future with all our stakeholders.

2019 ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT 38 Case Study: “Coal-to-gas” in Xiong’an Xiong’an New Area in Baoding, Hebei Province, is a state-level new area proposed by the State Council in 2017. It is of great significance for easing Beijing’s non-capital functions, optimizing the urban layout in the Beijing-Tianjin- Hebei region, and fostering a new engine for the innovation-driven development. Accordingly, there are much stricter requirements for Xiong’an than other cities in terms of ecological protection and clean energy supply. PetroChina proactively contributed to the construction of Xiong’an New Area through undertaking the “coal-to- gas” rural heating renovation project in 2019. This project benefits about 550,000 residents in 140,000 households 2 with an area of 1,460 km . It is expected to help save about 500,000 tons of coal annually, equivalent to reduction of about 1.5 million tons of wood. Local residents entered the “gas era”, accessing clean, safe and convenient natural gas. Efficient completion of “coal-to-gas” project The “coal-to-gas” project involves the vast countryside, where the geographical environment is relatively complex and the village infrastructure is weak. It corresponds to many risk points, a large work quantity, and a high time pressure. Nevertheless, through scientific coordination and efficient operation, PetroChina completed the coal-to-gas switch in just four months. Ultimately, the whole Xiong’an New Area can enjoy clean gas via the medium-pressure pipeline network connecting the high-pressure gas pipelines such as the Baxian-Baoding Pipeline and the Wen’an-Xiongxian Pipeline. Provision of smart and safe services PetroChina installed domestically advanced smart gas meters, which can simultaneously realize functions such as the remote transmission of operation data, automatic uploading of user information and mobile payment. Safety was ensured by the installation of gas alarm devices for each household. We actively respond to Increased gas supply To further satisfy gas demand in the Xiong’an New Area, PetroChina increased the supply of natural gas to the area by 150 million cubic meters. “Gas is much better!

He has won 19 awards, including the National Special Prize on Science & Technology Progress Award and the National Special Prize of the Science & Technology Achievement Award. His achievements are outstanding. The Efficient Water Injection Method overrides the popular moderate water injection in China and inaugurated a new solution to stabilize production in oilfields with middle to low water cut. The development mode of “separate-layer exploitation, and production stabilization in alternative manner” increased water flooding recovery by 10%~15% during the production test. The research on untabulated reservoir development implied the addition of 740 million tons of geological reserves for Daqing Oilfield. The new super-high molecular polymer flooding has contributed benefits close to RMB 300 million. In 2019, Wang was honored as the “People’s Model” by the Standing Committee of National People’s Congress and the “Superb Striver” by the Publicity Department of the CPC Central Committee. “I’ve done but one thing all my life, that is how to best develop the Daqing Oilfield”, says Wang Qimin.EMPLOYEE DEVELOPMENT 57 Case Study: “China Skills Carnival 2019 — Approaching PetroChina” In 2019, PetroChina carried out, in conjunction with the Ministry of Human Resources and Social Security and the State-owned Assets Supervision and Administration Commission of the State Council, the “China Skills Carnival 2019 — Approaching PetroChina”, or the Year for Promoting the Skilled Personnel Training and Development Project.

SOCIAL CONTRIBUTION 67 A Village-level Town was Formed through Meeting the Community’s Case Study: Requirements Gudawa, which is close to the Ronier Oilfield in Chad, was a small village with a population of less than 500, and without satisfactory and sufficient living infrastructure such as roads, school and water supply. In the dry season, villagers had to relocate to places close to the water source, which made them suffer an unstable life, lacking a decent education or better livelihood. PetroChina took over the Ronier Oilfield in 2011. Since then, the Company’s public relations department visited local communities to understand their needs. For clean drinkable water, PetroChina drilled 49 wells, benefiting 25,000 residents in 39 villages nearby including Gudawa. Moreover, PetroChina constructed the main road in Gudawa and a primary public school accommodating 300 students in six grades. The oilfield development also created job opportunities for local people – up to 969 people in total. The prosperity of Gudawa, typically the water wells and school, have attracted numerous people from other villages. Now, Gudawa has developed into a village-level town with more than 10,000 residents.

2019 ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT 80 GLOSSARY Liquefied natural gas is produced by dewatering, deacidifying, dehydrating and Liquefied natural gas (LNG) fractionating the natural gas produced from a gas field and then turning it into liquid under low temperatures and high pressure. New energy refers to unconventional energy and renewable energies, mainly including New energy CBM, shale gas, oil sands, oil shale, fuel ethanol, biodiesel, geothermal energy, wind energy, solar energy, hydrogen energy, water-soluble gas and NGH. A low-carbon economy is an economic development model characterized by low energy consumption, low pollution and low emissions. Its essence is efficient energy consumption, development of clean energy and pursuit of green GDP. The core of Low-carbon economy this model is the optimization of the industrial structure, low-carbon technology and institutional innovation. A low-carbon economy is developed by means of energy conservation, emissions reduction and the development of clean energy. Greenhouse gases are gases in an atmosphere that absorb solar radiation from the surface and then emit radiation, such as water vapor, CO , and most refrigerants. Their 2 Greenhouse gas (GHG) effect is making the Earth’s surface warmer, as the “greenhouse effect” sequestrates solar radiation and increases the temperature of the air. Greenhouse gases in the Earth’s atmosphere mainly include CO , CH , N O, HFC , PFC and SF . 2 4 2 S S 6 Also refers to carbon sinks. It is the process, activity and mechanism to remove carbon dioxide from the air. Generally, it indicates the capability of forests to absorb and Carbon sequestration store carbon dioxide. Carbon dioxide in the atmosphere is artificially sequestrated in biological forms in plants and the soil through forestation, forest management, and other forest carbon sequestration measures. HSE is the acronym of the health, safety and environment management system. The HSE management system is an integration of various elements such as organizational structures, mandates, practices, procedures, processes and resources used for health, HSE management system safety and environment management.
