Remarks:

- Revise 2020 - 2022 data for better accuracy
- In 2020, the total volume of water withdrawal has decreased due to the Water Conservation projects and the reduction of production of Rayong Gas Separation Plant Unit 1.
- In 2022, total water withdrawal in Water stress areas increased due to Pipeline Operations Center District 10, Chachoengsao Province, added water to the center's firefighting water storage pond.
- In 2023, the total volume of water withdrawal closely approximates that of 2022
- In 2022, there were a total of 15 sites located in water stress areas. These included Pipeline Operations Center Region 1, 2, 9, 10, 11, Chonburi Operations Center, PTT Innovation Institute, Main gas distribution stations at Kaeng Khoi, Nimmit Ma, Nimmit Mai 2, Ban Bung, Rangsit Pathum Thani, Lad Lum Kaeo, Lan Krabue, and Lam Luk Ka.
- From 2023, due to an update on WRI Aqueduct (Water Stress Area) version used to assess sites located in water stress areas, in the number of PTT sites in water stress area increased to 28 sites. These included Khanom Gas Separation Plant, Rayong Gas Separation Plant, Main gas distribution stations at Kalpapruek, Kaeng Khoi, Khon Kaen, Thung Kru, Nimmit Mai, Nimmit Mai 2, Ban Bueng, Rangsit Pathum Thani, Ladlumkaew, Lakorn Khae, Lad Lum Kaeo, Lan Krabue, Lam Luk Ka, PTT Head Office, Ban Rong Po LPG Terminal, Khao Bo Ya LPG Terminal, Sriracha Oil Terminal, Pipeline Operations Center Region 1, 2, 3, 4, 6, 9, 10, 11, 12, Chonburi Operations Center, and Onshore Operations Plant . Consequently, this resulted in an increase in the total water use within waste stress areas.
- The reported data does not include staff accommodation in Rayong province, as it is not under the operational control of PTT.

[2] Crude oil equivalent barrels (mboe) calculated from the sales product volume by PTT Public Company Limited.
- In 2023, the emission of NOx increased due to expanded production capacity, leading to higher volumes of Feed Gas entering the Rayong Gas Separation Plant. Additionally, there was an increased use of Natural Gas for electricity generation for internal supply, displacing the need for purchased electricity.
- In 2023 and 2024, the emission of SO2 increased due to expanded production capacity, leading to higher volumes of Feed Gas entering the Rayong Gas Separation Plant. Additionally, there was an increased in the proportion of hydrogen sulfide in the gas composition from upstream compared to 2022.
- In 2024, NOx emission decreases due to shutdown maintenance of gas saperation plant unit1 (GSP1) 10 days and 50% turndown of gas saperation plant unit 5 (GSP5) and unit 6 (GSP6) 111 and 36 days, respectively.

Remarks:

The organizational boundary of PTT Group based on the equity share approach includes all domestic subsidiaries in which PTT directly owns more than 20% of shares or indirectly owns 100% of shares.
• PTT’s indirect energy consumption is including electricity purchase from grid and electricity from solar panel installation at Innovation Institutes (InI), Khanom Gas Separation Plant, Gas Transmission Pipeline Operation Offices, NGV and Wangchan Valley.
• In 2023, PTT’s renewable energy consumption increased as the solar panels have been installed at Khanom Gas Separation Plant, Gas Transmission Pipeline Operation Offices, and Wangchan Valley. In addition, the indirect energy consumption decreased due to the reduction in purchasing electricity from external sources. Electricity production within the Rayong Natural Gas Separation Plant area has been initiated to replace purchasing from the grid. Meanwhile, direct energy consumption decreased because of halting the annual maintenance of Rayong Natural Gas Separation Plant unit 3.
• n 2023, the intensity of energy consumption in oil and gas production was affected by the termination of the "Bongkot Project " in the first quarter, combined with the transition to the new project, G2/61.
• In 2023, the energy intensity of petrochemicals increased due to the demand for electricity for the production of High-value products by PTT Global Chemical.
PTT Group’s indirect energy consumption is including electricity purchased and electricity from solar panel at PTT, PTTEP, GC, IRPC, TOP, GPSC, PTT Tank, Enco, PTTLNG
