Abstract

Based on the typical city survey data and statistics of Guangdong Province, a 2018-based 3 km×3 km gridded greenhouse gas emissions inventory was developed for Guangdong Province using the combination of top-down and bottom-up emission factor methods. The inventory covered the CO <subscript>2</subscript> , CH <subscript>4,</subscript> and N <subscript>2</subscript> O emissions from energy, industrial processes, agriculture, land use change and forest, waste management, and indirect sources. The results showed that estimates for CO <subscript>2</subscript> , CH <subscript>4</subscript> , and N <subscript>2</subscript> O in Guangdong Province for the year 2018 were 8.5×10 <superscript>8</superscript> , 1.9×10 <superscript>6</superscript> , and 1.1×10 <superscript>5</superscript> t, respectively, and 8.5×10 <superscript>8</superscript> , 4.0×10 <superscript>7</superscript> , and 3.4×10 <superscript>7</superscript> t by equivalent carbon dioxide, totaling 9.2×10 <superscript>8</superscript> t. CO <subscript>2</subscript> was the main greenhouse gas in Guangdong Province, accounting for 92.0% of the total emissions. Energy and indirect sources were the main emission sources, accounting for 77.9% and 7.6%, respectively, totaling 85.5%. Spatial distributions illustrated that most grids were greenhouse gas emissions, whereas some others were greenhouse gas sinks; the greenhouse gas emissions were distributed mainly in the Pearl River Delta region and had certain characteristics of distribution along the road network and channels. The greenhouse gas grids of high emission were mainly the locations of high energy-consuming enterprises such as large power plants, steel mills, and cement plants.
