这项研究旨在修改生态足迹方法，将不可再生或非生物资源作为一个额外的类别。利用热力学方法，非生物资源的使用可以量化为全球公顷。对澳大利亚、比利时、巴西、加拿大、日本、美国和越南等多个国家的详细案例研究表明，使用新的修正生态足迹(EF)作为可持续发展指标具有优势。修改后的生态足迹不仅包括生物资源，还包括非生物资源。实例研究表明，在比利时和澳大利亚的情况下，改进后的EF与传统EF的差异高达123%和90%。对于巴西和越南等发展中国家，差异相对较小(巴西为21%，越南为9.4%)。与使用原始生态足迹方法的结果相比，使用新方法估计的全球总生态足迹意味着与过度消费相关的更严重的问题。
This study is to modify the ecological footprint methodology by incorporating non-renewable or abiotic resources as an additional category. The use of abiotic resources can be quantified as global hectare by using thermodynamic approaches. A detailed case study on various countries including Australia, Belgium, Brazil, Canada, Japan, USA, and Vietnam shows the advantage of using the new modified ecological footprint (EF) as an indicator for sustainable development. The modified EF includes not only biotic resources, but also the abiotic resources. The case study indicates that the modified EF differs from the traditional EF up to 123% in the case of Belgium, and 90% in the case of Australia. For developing countries such as Brazil and Vietnam, the differences are relatively smaller (21% for Brazil and 9.4% for Vietnam). The estimated total ecological footprint of the world using the new method implies more serious problems associated with over consumption than using results from the original ecological footprint method.
