Since stating carbon peak goal, Shandong has garnered widespread concern over its large GHG emissions. Based on the latest emission factors and detailed activity data, a comprehensive highresolution GHG emission inventory of Shandong Province for 2020 was established by updating estimation methods and allocation profiles. The results indicated that the emissions of CO₂, CH₄, N₂O, HFCs, PFCs and SF₆ had reached 1233.46, 36.49, 45.79, 74.27, 6.21 and 0.56 Mt CO_2eq, respectively. Specifically, CO₂ emissions mainly originated from fossil fuel consumption (81.83%); the major sources of CH₄ emissions were mining industries and agriculture, contributing 1.40% and 0.81% of the total GHG emissions, respectively; industry processes and product use discharged the largest amount of N₂O (1.92%) and were responsible for all of the fluorinated greenhouse gas emissions. To obtain more accurate GHG emission information, GHG emissions were spatially allocated to grid cells with a resolution of 0.05°×0.05° according to appropriate surrogates and results showed that most of the emissions are concentrated over a small number of grid cells, specifically, 10% of grid cells accounts for 73% of GHG, 75% of CO₂, 88% of CH₄ and 40% of N₂O emission. Spatially, the GHG emissions were mainly distributed in eastern and central cities of Shandong and decreased radially from urban centres to the surrounding areas.
