Analysis Of Carbon Emission Reduction Potential And Abatement Cost In Typical Sectors Of Wuhan

As the climate gets warmer, greenhouse gas emissions and climate change issues increasingly become the focus of the world. In the post-Kyoto era, sectoral reduction becomes the main debate of the international climate conference, this research is based on the the view of sectoral reduction to study greenhouse gas emission reduction potential and abatement costs.Firstly, power and steel sector were selected as typical sectors, based on the energy distribution of Wuhan industry; then scenario analysis and LEAP model were used to estimate carbon emission reduction potential of power and steel sector of Wuhan, and to assess abatement costs of key technologies in typical sectors. On the basis, economically viable technical path and associated carbon emission reduction potential and abatement costs was given via the survey of the application of key abatement technology in typical sectors. Finally, based on low-carbon urban development policy Selection Tool?BEST Cities?, carbon emission reduction potential and abatement costs of low-carbon industrial policy in Wuhan was simulated to analyze and verify the carbon emission reduction potential and abatement cost of typical sectors based on LEAP model, and targeted policy recommendations were proposed. The main conclusions are as follows:?1? Compared with the baseline scenario, carbon emission reduction potential under energy efficiency limitation scenario and coal power action plan scenario of power sector was 130000 tons and 240000 tons in 2020, accounting for 1.1% and 2.0% of carbon dioxide emissions under baseline scenario, so carbon reduction potential of power sector is limited. However, based on cost analysis of specific carbon emission reduction technology, Wuhan power sector was advised to invest 400 million yuan to promote steam turbine operation optimization and other five energy-saving technologies in turn, which can reduce 714900 tons of carbon dioxide, much higher than the possible carbon emission reduction potential via scenarios analysis of Wuhan power sector. It is illustrated that Wuhan power sector need more stringent energy standard because power enterprises in Wuhan can reach a predetermined value policy advanced by promoting energy-saving technologies.?2? Compared with the baseline scenario, carbon emission reduction potential under energy efficiency improvement scenario and energy structure change scenario of Wuhan Iron and Steel sector was 1.91 million tons and 5.17 million tons in 2030, accounting for 6% and 16% of carbon dioxide emissions under baseline scenario, so carbon emission reduction potential of steel sector is large. however, the unit cost under energy efficiency improvements scenario and energy structure change scenario was-145.9 yuan / tCO₂ and 813.1 yuan / tCO₂, so energy efficiency improvement scenario was the most economical and viable path to carbon emission reduction of Wuhan Iron and Steel sector currently. Based on cost analysis of specific carbon emission reduction technology, Wuhan Iron and Steel sector was advised to invest 1.5 billion yuan to promote dry TRT and other four technologies in turn, which can reduce 940000 tons of carbon dioxide, accounting for about 2.8% of carbon emissions of Wuhan Iron and Steel industry in 2014.?3?To achieve carbon emissions reduction of Wuhan industry, Wuhan should vigorously improve the carbon trading system; pay attention to the promotion of old power plants, and develop the lowest standard of energy efficiency or carbon emission of power sector; develop renewable energy and non-fossil energy targets or quotas; attach importance to the basis work of energy saving and carbon emission reduction; develop local energy consumption limitation standard in typical sectors.
