A review of recent multi-region input–output models used for consumption-based emission and resource accounting
Thomas Wiedmann
Abstract：
The interest in consumption-based emission and resource accounting has grown significantly.Many studies juxtapose consumer emissions (carbon footprint) and producer (territorial) emissions of greenhouse gases in order to demonstrate the effects of trade on the national emission budget.To this end,a respectable number of studies have been undertaken worldwide in order to estimate emissions embedded in international trade of numerous countries and world regions.Input–output approaches,and increasingly multi-region input–output (MRIO) models,are commonly chosen as they provide an appropriate methodological framework for complete carbon footprint estimates at the national and supra-national level.With increasing processing capabilities of computers and a wider availability of economic accounts,environmental accounts and trade data such models are now being implemented on a wide scale.After a brief overview of salient single-region input–output studies I provide an in-depth review of the most recent multi-region input–output models used for the purpose of consumption-based environmental accounting.The main methodological features and important results are described for around twenty studies covering the years 2007 to 2009.This is followed by a detailed review of studies dealing with uncertainty in MRIO analysis,an area which has not received a lot of attention so far.I conclude that further research is mainly needed in two areas,a) improvements in data availability and quality and b) improvements in the accuracy of MRIO modelling.

一个关于当前多区域投入产出模型的评审.这个模型是用于消费型排放和计算资源开销的.
托马斯 维德曼
摘要：
对于消费型排放和计算资源开销的关注不断的提高.许多关于温室气体的消费型排放（炭追踪）和生产型（本土的）排放的学术研究试图说明国家之间拿排放预算进行交易的效应.为此,相当多的研究在世界范围内进行,用以预测将排放纳入为数众多的国家和地区的国际贸易之中是否靠谱.投入产出法和日渐增多的MRIO模型,被广泛的用来作为一个适当的方法学框架.这个框架可以完成在国家之间和超越国家水平上的对于炭排放路径的估计.随着计算机处理能力的提高和财政预算、环境预算以及贸易数据的更加广泛的可用性,这类模型现在正被广泛的应用.在对突出的单区域投入产出的相关研究做出简明概要之后,我提出一个全面的评审.这个评审是关于最新的用于消费型环境预算的多区域投入产出模型的一个评审.主要的方法的关键点和重要结论是围绕2007~2009年间的20项研究展开的.而紧接着会给出一份详细的有关研究的评审.这些研究的内容是关于处理MRIO分析中的不确定性.而这些研究的内容到目前为止并没有受到广泛的关注.因此我得出结论,更深入的研究在一下两个方面是非常必要的.
a）提高数据的可用性和质量
b）提高MRIO模型的准确度
