The ecological resource potential (ERP) method allows to calculate the amount of one material that can potentially be produced within Earth system boundaries, if no other anthropogenic activity would take place. It indicates the uppermost potential of one resource extracted, processed and disposed after use with a specific set of technologies and a defined probability of violating Earth system boundaries. This method is an adaption of the ecological resource availability (ERA) method, which calculates the amount of a resource that can be produced within an allocated share of the global boundaries, i.e. when considering all other anthropogenic activities. While more realistic, its allocation can be done in multiple ways and based on a variety of different objectives, which requires scenario modelling. The ERP method, in contrary, only requires information on environmental impacts from resource extraction, processing, and final disposal. The customization of the original ERA method comprises:•Omitting all steps for allocating global boundaries to single resources or resource segments.•Changing the calculation procedure so that ERP is calculated for each resource separately.
生态资源潜力(ERP)方法能够计算出在地球系统边界内,如果不发生其他人为活动,一种物质可能产生的数量。它表明了在使用特定技术集并具有违反地球系统边界的特定概率的情况下,一种资源在提取、加工和使用后处置的最大潜力。该方法是对生态资源可利用性(ERA)方法的一种改进,ERA方法计算的是在全球边界的分配份额内,即在考虑所有其他人为活动的情况下能够产生的资源量。虽然ERA方法更现实,但它的分配可以通过多种方式并基于各种不同目标来进行,这需要情景建模。相反,ERP方法只需要有关资源提取、加工和最终处置的环境影响的信息。对原始ERA方法的定制包括:
• 省略将全球边界分配给单一资源或资源段的所有步骤。
• 改变计算程序,以便分别为每种资源计算ERP。
