英文文献摘要：
This paper develops a dynamic, regional analysis of the effects of US and European biofuel mandates on land use, forestry stocks, and carbon emissions. The results suggest that these mandates may cause an additional 23-26 million hectares of forestland losses globally, but additional carbon emissions of 1.2 – 1.6 billion t CO2. The estimates are found to be sensitive to the elasticity parameter on the land supply function in the model, with the higher elasticity estimates associated with larger carbon losses. The regional analysis turns out to be quite important, because some regions end up gaining forestland and increasing carbon stocks. The regional and dynamic effects have been missed by most other noteworthy analyses of the induced land use effects of biofuel policies, potentially leading the authors to overstate the impacts by 3-6 times.
本文对美国和欧洲的生物燃料法令对土地利用、林业库存和碳排放的影响进行了动态的、区域性的分析。研究结果表明，这些法令可能会导致全球额外的2300万至2600万公顷森林面积的损失，但会增加12至16亿t二氧化碳的排放。我们发现，这些估计值对模型中土地供应函数的弹性参数很敏感，弹性估计值越高，碳损失越大。区域分析结果是相当重要的，因为一些地区最终获得了林地，增加了碳储量。关于生物燃料政策诱发的土地利用效应的其他大多数值得注意的分析都忽略了区域和动态效应，这可能导致作者将这些影响夸大了3-6倍。
