Sustainable development: Sustainable development takes into account all aspects related to the business (i.e.) raw materials, human and economic system.
Sustainable development can produce products and services that meet the desires and human needs while preserving the environment for future generations.
We can then say that sustainable development is linked with ethics.
The World Commission on Environment and Development United Nations defines sustainable development in 1987 this way:
"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
The ecological footprint is a tool to evaluate the quantity of energy used for the production of a product or service. Can then be compared with this tool the difference between what natures provides us and what we consume.
It is used to make predictions but also to measure human actions on the environment. It measures not only for human consumption but also of a country, or even the planet nature necessary for the production of an object.
E. Williams REES one of the two creators of the term suggests the following definition:
"The ecological footprint is the corresponding area of productive land and aquatic ecosystems required to produce the resources consumed and to assimilate the wastes produced by a defined population at a specified material life. '
The carbon balance: The carbon footprint is a tool to quantify the greenhouse gas effect greenhouse (GHG) emissions of a company or an administration. These emissions can be direct or indirect. Carbon footprint to become much more important than the ecological footprint as international governments based GHG limits on companies that are based on the calculation methods.
The great strength of the carbon footprint that is compatible with the ISO 14064 and 14065 with the theme here is the official definition proposed by ADEME:
"A method of accounting for emissions of greenhouse gases from readily available data to arrive at a proper assessment of direct or indirect emissions from your business or territory."
These definitions related to the various international meetings and scientific reports have led to the emergence of these themes in world governments. The Kyoto Protocol in 1997 was the first meeting has taken quantified commitments. It aims to reduce emissions of greenhouse gases (GHGs).
