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]
The EVR model is a life cycle assessment based method to analyse consumption patterns, business strategies and design options in terms of eco-efficient value creation. Next to this it is used to compare products and service systems (e.g. benchmarking).
According to him, the development of the concept of eco-efficiency allowed the development of the TBL model, a framework that he believes can save businesspeople from ecological communism". [25] Eco-efficiency is equivalent to weak sustainability and corresponds to a relative measure of socio-environmental impacts compared to value creation.
The formula is the NPP = GPP - R. [4] The NPP is the overall efficiency of the plants in the ecosystem. Through having a constant efficiency in NPP, the ecosystem is then more sustainable. The GPP refers to the rate of energy stored by photosynthesis in plants. The R refers to the maintenance and reproduction of plants from the energy expended.
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 ( I n / P n − 1 {\displaystyle I_{n}/P_{n-1}} )
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 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]
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.
