Germany alone spends more than $3 billion annually, or $167 per ton of avoided CO2 emissions, which is more than 37 times the cost of carbon reductions in the European Union Emissions Trading System. And the estimate of avoided emissions ignores indirect land-use changes, making the likely real cost at least eight times higher.
与此同时，我们却为生物燃料付出了高昂的代价。仅德国一地每年就需多支出超过30亿美元，合每吨二氧化碳减排多支出167美元，超过了欧盟排放交易系统碳减排定价的37倍。而对减排量的估算并未计算间接的用地变化，因此可能的实际成本至少在8倍以上。
