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 efficiency of algorithms affects the amount of computer resources required for any given computing function and there are many efficiency trade-offs in writing programs. Algorithm changes, such as switching from a slow (e.g. linear) search algorithm to a fast (e.g. hashed or indexed) search algorithm can reduce resource usage for a given ...
Here also, depending on authors' definitions, the boundary between efficiency and sufficiency may not always be perfectly drawn. As an illustration, a report for UNEP classifies items such as reducing living spaces, driving smaller cars and car sharing as material efficiency, while they would be more traditionally viewed as sufficiency.

Resource efficiency is the maximising of the supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively, with minimum wasted resource expenses. It means using the Earth's limited resources in a sustainable manner while minimising environmental impact.
Eco-labeling standardization is a new form of regulation which is voluntary in nature but impose upon large companies market forces in order to harmonize production of goods and services with stronger ecological practices. Recently, it has turned into a new form of non-state authority at both national and international levels.

In order to achieve sustainable consumption, two developments have to take place: an increase in the efficiency of consumption, and a change in consumption patterns and reductions in consumption levels in industrialized countries and rich social classes in developing countries which have a large ecological footprint and set an example for ...
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}} )
