The Research On Carbon Emissions Factors And Low Carbon Development Strategies In Hunan Province

Global warming has become an indisputable fact. The main cause of climatewarming is the increase of the concentration of greenhouse gases in the atmosphere,and human activities affect carbon dioxide emission which is a main part ofgreenhouse gases. Hunan Province is an important province of central China, and CZTcity cluster approved as the national "Two-oriented society" for development andreform experimental zone. There was great significance to study Hunan Province CO₂emissions and emission reduction measures on sustainable development of HunanProvince and rest of the country.First, this paper analyzed the total energy consumption and changes in thesituation in Hunan Province. And using the IPCC（2006） general method to calculatethe total carbon dioxide emissions of Hunan energy consumption from1995to2007.Then Analysising the changing circumstances of total emissions, industry andconsumption emissions of carbon dioxide. The results showed that the main energyconsumption was industrial. Energy consumption of the province generally showedupward situation, Coal was the main part of energy consumption. The increase inenergy consumption caused rapid increase of carbon dioxide emissions in HunanProvince. The total emission from104.517million tons in1995increased to217.563million tons in2007. Secondary industry which was the largest contribution to carbondioxide emissions determined emissions situation.Second, based on the LMDI model, industrial carbon dioxide emissions in HunanProvince was decomposed to integrated emission coefficient factor, energy intensityfactors, industrial structure factor and industry output factor. The results showed thatoutput growth was the main growth driver of carbon dioxide emissions, and it’scontribution rate was89.67%. Industrial output growth was the greatest contributionfactors. The decline of energy intensity was the main driving factor for reducingcarbon dioxide emissions. The five major industries contributing to the increase incarbon dioxide emissions in order was: industry accounted for73.91%, transport,storage, postal and telecommunication services accounted for12.2%, wholesale andretail trade, catering industry accounted for10.54%, construction2.74%, agriculture,forestry, animal husbandry and fishery accounted for0.58%.Third, this paper used decomposition model to analysis carbon dioxide emissionintensity factors including industry and consumption. The analysis showed that the decline in industrial energy intensity was the most important reason to decreasecarbon dioxide emission intensity in Hunan. The decline of secondary industry energyintensity was the greatest contribution. Reducing industrial energy consumption wasthe most important way to reduce the integrated carbon dioxide emissions intensity inHunan. In addition, there was large potential to decline living energy intensity.Low-carbon consumption and saving energy consumption should be promoted in ourlife. Reducing the thermal power in the energy mix ratio could effectively reduce CO₂integrated emission intensity.Last, according to the actual situation of Hunan Province and guided by theprinciples of sustainable development and new economic growth point, this paparexplored countermeasures of Hunan low-carbon development in terms of energysupply, industry, transportation, construction, agriculture and forestry, life, etc.
