Abstract

Abstract Cellulosic biofuels from non-food feedstocks, while appealing, continue to encounter uncertainty about their induced land use change (ILUC) effects, net greenhouse gas (GHG) saving potential and their economic costs. We analyse the implications of multiple uncertainties along the biofuel supply chain from feedstock yields, land availability for production to conversion to fuel in the refinery on these outcomes. We find that compared to corn ethanol, cellulosic biofuels have a substantially smaller and less uncertain ILUC-related GHG intensity and lead to larger GHG savings at lower welfare costs of abatement, indicating the potential to make robust and substantial contributions to cost-effective climate change mitigation.
量化温室气体节约和纤维素生物燃料减排成本的不确定性
来自非粮食原料的纤维素生物燃料虽然很有吸引力,但在其诱导的土地利用变化(ILUC)效应、净温室气体(GHG)节约潜力及其经济成本方面仍面临不确定性。我们分析了生物燃料供应链上从原料产量、生产土地可用性到炼油厂转化为燃料的多重不确定性对这些结果的影响。我们发现,与玉米乙醇相比,纤维素生物燃料与iluc相关的温室气体强度要小得多,不确定性也更低,并以更低的减排福利成本节省更多的温室气体,这表明有可能为具有成本效益的气候变化缓解做出强有力的实质性贡献。

期刊介绍: The European Review of Agricultural Economics serves as a forum for innovative theoretical and applied agricultural economics research. The ERAE strives for balanced coverage of economic issues within the broad subject matter of agricultural and food production, consumption and trade, rural development, and resource use and conservation. Topics of specific interest include multiple roles of agriculture; trade and development; industrial organisation of the food sector; institutional dynamics; consumer behaviour; sustainable resource use; bioenergy; agricultural, agri-environmental and rural policy; specific European issues. Methodological articles are welcome. All published papers are at least double peer reviewed and must show originality and innovation. The ERAE also publishes book reviews.
