适用于可持续认证的生物质能温室气体排放核算方法

 能源领域可持续认证标准要有温室气体（greenhouse gas，GHG）排放核算方法作为支撑。中国尚未开发适用于生物质能可持续认证的GHG排放核算方法。本文梳理了GHG排放核算的一般方法，基于国外生物质能可持续政策要求与认证标准的相关方法学，识别出核算方法的关键要素。在对中国研究层面生物质能生命周期GHG排放核算不同认识进行梳理和讨论的基础上，提出了适合于中国可持续认证的核算方法的建议。

Calculation of greenhouse gas emission in bioenergy sustainability certification

The calculation of the Greenhouse Gas (GHG) emissions is an important component in the sustainability certification of the energy product, but so far without an adequate methodology consistent with the certification requirements of the bioenergy sustainability in China. This paper presents the key elements involved in the GHG emission calculation for the bioenergy sustainable certification. Firstly, the general method of the GHG calculation is briefly presented. Then, based on the review of the methodologies of the bioenergy sustainability standards developed by the institutions in the world, the key elements of the calculation methodology are identified and analyzed. Finally, the paper analyzes different understandings in the current LCA analysis in China and makes preliminary suggestions on developing the GHG calculation methodology of the bioenergy for the sustainability certification in China.
