摘要
为深入分析国际海事组织(IMO)给出的船用含碳燃料碳转换系数的合理性,基于文献阅读法,追溯IMO碳转换系数的相关决议和提案,分析碳转换系数计算方法,发现IMO碳转换系数存在所采用的碳、氢、氧原子量近似值不统一,基础数据源未更新等问题,其会影响到国际海运碳排放精度。针对上述问题,修正了船用含碳燃料碳转换系数;计算得到IMO未给出的乙烷、生物汽油/柴油的碳转换系数;提出了适时修订船用含碳燃料碳转换系数的IMO提案,我国在引用IMO碳转换系数作为国内碳排放核算系数时应审慎对待等建议。
The documents concerning the calculation of conversion coefficients for marine fuels are reviewed to see the rationality of the conversion coefficients given by IMO.The method of calculating the coefficients is analyzed.Inconsistency in given atomic weight approximations for carbon,hydrogen and oxygen is found.Besides,the fundamental data source is not up to date.These problems are degrading the accuracy of carbon emission calculations.The corrections for the conversion coefficients are proposed.The conversion coefficients for ethane and bio-gasoline/biodiesel are calculated.A proposal on timely revising the conversion coefficients is prepared.Prudent treatment is suggested in using the conversion coefficients given by IMO to evaluating domestic emissions.
