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 eco-costs/value ratio (EVR) is an indicator to reveal sustainable and unsustainable consumption patterns of people. The eco-costs is an indicator for the environmental pollution of the products people buy, the value is the price they pay for it in our free market economy .
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.
Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]
A lot of companies using ecopreneurship principles incorporate sustainable product design. Product design incorporating sustainability can happen at any stage of the business, including material extraction, logistics, the manufacturing process, disposal, etc. Sustainable product design can be achieved using innovative technology (or Eco-innovation), cradle to cradle design, bio-mimicry, etc.
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}} )
Measurable energy conservation and efficiency gains in the 1980s led to the 1987 Energy Security Report to the President (DOE, 1987) that "the United States uses about 29 quads less energy in a year today than it would have if our economic growth since 1972 had been accompanied by the less- efficient trends in energy use we were following at ...
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.
