Cleantech : These are industrial techniques and services that use natural resources - water, energy, raw materials - to improve efficiency and productivity. This method allows a systematic reduction in the volume and toxicity of waste while guaranteeing the same or even better performance than existing technologies. 

EPD : Environmental Product Declaration. Life cycle analysis to find out the environmental impact of a product. Established in Europe, according to the EN 15804 standard, implemented and framed by the ISO 14020 and ISO 14025 standards.

Ecofeminism : Movement initiated in the United States that defines itself as philosophical, ethical and political, resulting from the junction between feminist ideas and actions and environmentalist impulses.

Ecogestures : Each one of us can carry out ecogestures. They reduce pollution and in fact improve the environment. They form the good practices of daily ecology (or practical ecology). They must be adapted to the habits and customs of the countries.  

Ecoresponsible: is said of someone who does his or her utmost to preserve nature and the environment. 

Ecosystem: Basic ecological unit of the environment (biotope) and the organisms living in it (biocenosis). For example, marine environments, deserts, mountains, forests are ecosystems.  

Greenhouse effect : Heating of the earth (surface) and the atmosphere (lower layers), created by the absorption and return of part of the infrared radiation of certain gases emitted by the earth and the compensation of the sun's radiation absorbed by it. 

Rebound Effect : This is the difference between the positive side of energy efficiency such as building insulation, improved heating systems, and less energy-intensive vehicles, and the negative side of increased use such as higher temperatures in homes and longer travel distances. The beneficial effect of efforts in terms of ecological economy is therefore cancelled out by an increase in consumer habits and customs.

Grey energy : Also called embodied energy, is the amount of energy used throughout the life cycle of a material or equipment. The stages are: production, extraction, transformation, manufacturing, transportation, implementation, maintenance and recycling. This is masked, non-direct energy (as opposed to easily traceable use). Grey energy is human, animal, electrical, thermal, etc... The addition of these factors can determine the need for a product throughout its life cycle. The knowledge of these calculations will guide the consumer towards a reduction of the environmental impact thus generated. 

Green Tech : The Green Tech Community, initiated by the Ministry, is a new approach of the collective to better achieve sustainable development objectives. The fusion of digital and green transition has generated the creation of a community of values, supported by smart grids and data sharing. A new development model, gas pedal of technological innovation and promoter of wealth and employment is emerging thanks to GreenTech verte. A new kind of digital and ecological thinking in a nutshell.

Greenwashing : a marketing or advertising method chosen by a structure to illusion on its eco-responsible commitment false. Other possible names: "greenwashing" "greening".

Low Tech : In French "basse technologie". Is opposed to high-tech. These are practical, popular, economical, simple techniques, one of the characteristics of which is to consume recycled obsolete machines. 

Mixity : The term mixité only appeared in 1963 in our French dictionaries. The very old term "mixed" meant "to mix" and was related to the education of girls. After the Second World War, co-education was related to women's rights or more generally to equality between men and women. Today, co-education tends to become diversity, i.e. the absence of all forms of discrimination and segregation. Definition according to Marie Donzel, for the blog EVE. Case of social mix: simultaneous presence or cohabitation, in the same place, of individuals of different nationalities, cultures, ages, socio-professional categories.

Programmed obsolescence : Techniques put in place by equipment manufacturers to consciously reduce the lifespan of equipment, to encourage faster replacement. A few examples: equipment that is not designed for the evolution of technologies, weakening of connection cables, wearing parts and "consumables" with a short life span.

Digital pollution : Digital pollution is the set of negative environmental impacts due to the effects of digital - information and communication technologies.

Ecological resilience : This is the ability of a living system to recover its entire initial organization after a crisis or disorder. The quality of resilience can bring about profound changes in the structure and activity of an ecological system. Good resilience is ensured by bio-diversity and respect for the ecosystem, whereas, on the other hand, human activity can undermine the quality of resilience of the ecology.

CSR : Corporate Social Responsibility This is the integration, by the company, of ethical and social issues in its activities, whether economic, internal and external interactions.

Digital Sobriety : An approach taken to minimize the impact of digital technology on the environment. The expression comes from the association GreenIt (2008) to encourage a more sober use of digital technology on a daily basis.  

Ecological transition : Set of principles and practices used to evolve and renew an economic and social model.
