Abstract: The 2015 Paris Agreement proposed that the global average temperature rise by the end of the century should be controlled within 2 ℃ above pre-industrial levels. In order to actively respond to climate change, the Chinese government has put forward the goal of “carbon peaking by 2030 and carbon neutrality by 2060”. However, the economic transformation under low-carbon operation still faces severe challenges. In this regard, based on the carbon market, carbon trading and carbon policy, the status of global CO₂ emissions and the energy transformation measures taken by international oil and gas companies for the dual carbon goal were investigated and analyzed with data mining and artificial intelligence data analysis. Based on the status of carbon emission in China and the practical decarbonization technologies in the oil and gas field, four key recommendations for decarbonization pathways were put forward, including popularizing new low-carbon material and technologies, promoting general carbon market standards, formulating protective policies for green transformation enterprises, and encouraging low-carbon research and development. What's more, five key areas for the energy transformation of oil companies in China were proposed, which are accelerating low-carbon development and exploration of oil and gas, carrying out carbon footprint full-chain evaluation, promoting intelligent and intensive development of shale gas, expediting research and development of hydrogen energy and CCUS technology. The research results can provide a valuable reference for the achievement of the dual carbon goal and the smooth transformation of oil companies.
