According to the WBCSD definition, eco-efficiency is achieved through the delivery of "competitively priced goods and services that satisfy human needs and bring quality of life while progressively reducing environmental impacts of goods and resource intensity throughout the entire life-cycle to a level at least in line with the Earth's estimated carrying capacity". [6]
Ecological efficiency is a combination of several related efficiencies that describe resource utilization and the extent to which resources are converted into biomass. [1] Exploitation efficiency is the amount of food ingested divided by the amount of prey production (/)
The boundary between efficiency and sufficiency actions are not always precisely set; some authors have a broad conception of efficiency that may include aspects of lifestyle change. Academic work released in 2022 systematically classified and databased specific public policy measures that can, individually and collectively, contribute to the ...
Ecological efficiency may be anywhere from 5% to 20% depending on how efficient or inefficient that ecosystem is. [8] [1] This decrease in efficiency occurs because organisms need to perform cellular respiration to survive, and energy is lost as heat when cellular respiration is performed. [1]
It has been noted that improvements in resource efficiency can occur at production, consumption, and end of product life stages. [2] Resource efficiency measures, methods, and aims are quite similar to those of resource productivity/resource intensity and of the slightly more environmentally-inclined concept of ecological efficiency/eco-efficiency.
Ecological economics, bioeconomics, ecolonomy, eco-economics, or ecol-econ is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economies and natural ecosystems, both intertemporally and spatially. [1]
The eco-costs of global warming (also called eco-costs of carbon footprint) can be used as an indicator for the carbon footprint. The eco-costs of resource scarcity can be regarded as an indicator for 'circularity' in the theory of the circular economy. However, it is advised to include human toxicity and eco-toxicity, and include the eco-costs ...
The ‘gospel of eco-efficiency’ is concerned with the efficiency of the production process, that is, the efficiency of the technologies involved in it. It focuses on finding solutions that improve the efficiency of resource use and of waste/pollution generation, mainly through investment in research and development .
