Embodied carbon emissions in Hainan Province based on input-output model
Utilizing the input-output tables and corresponding energy consumption data from Hainan Province in the years of 2007,2012,and 2017,the non-competitive input-output model was used to estimate the embodied carbon emissions of 26 sectors in Hainan Province,and analyzes the carbon emission intensity.The outcomes revealed that:1)From 2007 to 2017,the direct carbon emissions of Hainan Province surged from 26.02 million tons to 47.61 million tons,representing an annual growth rate of 5.16％.The main sources of carbon emissions are the service industry,production and supply of electric power and thermal energy,chemical industry,transportation and storage,postal & telecommunications services,paper printing and cultural,educational and sports articles.2)Most sectors ran into carbon deficits in both foreign and domestic commerce.Hainan Province gains environmental benefits from trade by importing products with high carbon emission intensity such as smelting and pressing of metals and metal products,and exporting low-carbon products like farming,forestry,animal husbandry,fishery & water conservancy,construction,transport,storage,postal &telecommunications services.In 2017,this province facilitated the transfer of 40.97 million tons of carbon to other regions via trade.3)Over the decade spanning from 2007 to 2017,both direct and embodied carbon emission intensity of industrial sectors in Hainan Province decreased significantly,with direct carbon emission intensity decreasing from 0.7 tons/CNY 10 000 to 0.38 tons/CNY 10 000 and embodied carbon emission intensity decreasing from 1.36 tons/CNY 10 000 to 0.63 tons/CNY 10 000.In addition,the number of sectors with high embodied carbon intensity(greater than 1.5 tons/CNY 10 000)shrank from 13 to 4.
