PTT Public Company Limited or simply PTT is a Thai state-owned SET-listed oil and gas company. Formerly known as the Petroleum Authority of Thailand, it owns extensive submarine gas pipelines in the Gulf of Thailand, a network of LPG terminals throughout the kingdom, and it is involved in electricity generation, petrochemical products, oil and gas exploration and production, and gasoline retailing businesses. The company also owns Café Amazon, a popular coffee chain throughout South East Asia, which shops are often located next to PTT gas stations or inside malls. Affiliated companies include PTT Exploration and Production, PTT Global Chemical, PTT Asia Pacific Mining, and PTT Green Energy. On 15 December 2022, the world's largest institutional investor the Norwegian Government Pension Fund Global divested from PTT and its subsidiary PTT Oil and Retail Business PCL due to "unacceptable risk that the companies contribute to serious violations of individuals’ rights in situations of war or conflict".
