Carbon Emissions Calculation Of Gasoline And Diesel Fuel Based On Life Cycle Assessment

In recent years,climate change caused by global warming have become increasingly prominent.Correspondingly,environmental regulations are increasingly stringent.Improvement and development of carbon taxes and carbon labeling has been the main trend of low-carbon economy.As one of the major source of greenhouse gas emissions,carbon emissions of fuel combustion from road transport pose a severe challenge to the automotive industry and refineries.Low carbon emissions of vehicle and carbon responsibility system for refineries has became a trend.To adapt to low-carbon development,it is a necessary requirement to do well of the calculation of carbon emissions from fuel.Firstly,on the basis of Life Cycle Assessment,the paper divides the full life cycle of gasoline and diesel into five stages to calculate the carbon emissions from fuel,including oil exploration,oil transportation,fuel production,fuel transportation and car use.Taking into account of the characteristics of each stage,then establish the methods and models of every stages to calculate carbon emissions.Secondly,focus on researching the calculation methods and model of the producing stage.By analyzing the characteristics of carbon emissions in this stage,the method of emissions calculation is determined based on activity-based costing method.And then to calculate carbon emissions from the refinery production stage of gasoline and diesel products with different grades and different quality.With the analysis,the paper concluds that: in refinery production stage,gasoline and diesel from different refinery has different carbon emissions;for the same refinery,gasoline release more carbon emissions than diesel;as for gasoline,carbon emissions from gasoline 95# is generally higher than gasoline 92#;as for diesel,regular diesel produces more carbon emissions than the diesel using in vehicles.Finally,based on life cycle analysis,the paper calculates the carbon emissions of gasoline and diesel from selected refineries,and then make comparation and analysis of various stages.In summary,the results of the paper can be used to estimate gasoline and diesel from different refinery processing routes as well as different grades of different quality of gasoline and diesel products.In order to provide the basis data for energy saving of oil products.And it also can be used for refineries to choose different processing routes by providing carbon emissions data,but also can prepare for the gasoline and diesel products to determine carbon tax and carbon labels.
