为了更好地理解人类对生物圈吸收废物能力的需求，本文引入了一种新的基于足迹的指标--“废物吸收足迹”(WAF)。世界自然基金会的提出灵感来自于在自然的多种生态功能上建立足迹的想法。在这一框架内，WAF建立在陆地和水域的废物吸收能力的基础上。这种方法并不局限于特定的废物产品，而是能够包括人类活动产生的各种废物。通过这种方法，人类排放的废物被转化为可吸收的土地和水域。结果可以用平均公顷为单位，根据不同土地利用类型的相对吸收能力来衡量其比例。生态足迹在可持续发展评价中的作用可以通过结合WAF来充分捕捉人为废物排放所造成的环境影响而大大加强。本文还讨论了WAF与其他足迹的关系，旨在为未来关于足迹核算的辩论提供参考。
For a better understanding of human demand on the biosphere's capacity to assimilate wastes, this paper introduces a new footprint-based indicator, which is named the ‘Waste Absorption Footprint’ (WAF). The proposal of the WAF is inspired by the idea of building footprints on nature's multiple ecological functions. Within this framework, the WAF is built upon the waste absorptive capacity of the land and water area. This methodological approach is not confined to a particular waste product, but is able to include a variety of wastes generated by human activities. With this method anthropogenic emissions of wastes are translated into absorptive land and water areas. The results can be expressed in units of average hectares by scaling different land-use types in proportion to their relative absorptive capacity. The utility of the ecological footprint in sustainability evaluation can be greatly strengthened by combining the WAF to fully capture environmental effects induced by anthropogenic emissions of wastes. This paper also discusses the relationships of the WAF with other footprints and is intended to inform future debate on footprint accounting.
