Examples of ecosystems: sea, pond, forest, mountain… All of Earth’s ecosystems make up the biosphere.

ENERGY POSITIVE

A concept designating a building (or house) that produces more energy than it consumes.

ENERGY LABEL

Created by the European Commission, it is compulsory. It identifies products whose use saves energy. Class A includes the products that perform best in terms of energy saving. The most energy-consuming products are labelled G

ENVIRONMENTAL FOOTPRINT

It assesses the area and the resources required to maintain a constant standard of living and ensuring elimination of waste. The higher the standard of living, the larger the footprint, and thus the greater the consumption of natural resources.

G

GREEN STICKER

First introduced in 1998 in France; identifies the least-polluting vehicles. If pollution levels are high and alternating traffic is resorted to, “green sticker” cars are not subject to the restriction.

O

OZONE LAYER
