But, by year 2023, the emission reduction due to fossil fuel displacement would be higher than that emission release due to land conversion thereby causing net reduction of GHG emissions. Starting 2032, there would be no more release of GHG emissions from land-use change as well, instead there would be reconversion of crop lands to pasture and forest lands thereby causing net sequestration of GHG emissions. This is because biofuel mandates and targets beyond 2020 are assumed to be kept at 2020 level. Thus, the analysis demonstrates that expansion of biofuels causes increase in global GHG emissions in the short-run but reduces GHG emissions in the long-run as long as biofuel mandates remain at the same level.

但到了2023年,由于化石燃料替代造成的减排量将高于由于土地转化造成的减排量,从而导致温室气体排放量净减少。 从2032年开始,土地利用变化的温室气体排放量将不再释放,而是将农作物的土地重新转化为牧场和林地,从而造成温室气体排放净固定。 这是因为假设2020年以后的生物燃料任务和目标将保持在2020年的水平。 因此,分析表明,生物燃料的扩张在短期内会导致全球温室气体排放量的增加,但只要生物燃料的使用量保持在同一水平,就可以在长期内减少温室气体的排放量。

但,直到2023年,由于化石燃料被取代而导致的排放量的减少量将会高于因为土地转化而导致的温室气体的净减少量。从2023年开始,也将不会有更多地温室气体因为土地利用的变化而被排放。取而代之的是将会有种植土地被还原为草原和森林,凭借于此,温室气体的排放将会被封存。这是因为2020年之后的生物燃料的管理和目标被假定为能保持在2020年应该有的水平。因此,分析表明生物燃料的大面积使用在短期内导致了全球温室气体排放量的增加,但只要使生物燃料管理能保持在相同水平上,生物燃料的大面积使用在长期内能够减少了温室气体的排放量本回答被提问者采纳
