Respectueux de l'environnement, ou respectueuses de l'environnement, est un terme appliqué aux marchandises, services, processus ou les gens censés pour faire des dommages minimes à l'environnement. Le terme est l'abréviation de « écologique », l'écologie étant l'étude des relations entre les êtres vivants et leur environnement.

Fossil fuels are the deposits of crude oil, natural gas and coal formed by the decay, over millions of years, of organic material (plants, trees animals and bacteria). Because the combustion of fossil fuels releases carbon that has been out of the natural carbon cycle for so long (unlike with living or more recently dead organic matter, known as biomass) it affects the balance between stored carbon and carbon present in the atmosphere as CO2, a greenhouse gas.

Liquid (or 'liquefied') petroleum gas (LPG) is a mixture of butane, propane and other light hydrocarbons produced either as a by-product of oil refining or from natural gas fields, and used as a vehicle fuel with lower CO2emissions than petrol. At standard temperature and pressure, it's a gas but the mixture can be cooled, or subjected to moderate pressure, and is then transformed into a liquid for ease of storage and transportation. LPG is used in dual-fuel vehicles, where it operates alongside a conventional petrol tank. It is also used in heating appliances.

Its light is produced by an electrical current passing through a semiconductive material, so it does not require a filament like an incandescent bulb. They have a long life span, are durable, more energy efficient than CFLs, or incandescent bulbs cool to the touch and, while they have traditionally been used as small indicator lights, multiple LEDs are increasingly being used for household lighting.

An international agreement adopted in December 1997 in Kyoto, Japan. The protocol sets binding greenhouse gas emissions targets for developed countries that would reduce their emissions on average 5.2% below 1990 levels.
Industry:Natural environment
Global warming refers to the increase in the earth's surface (or near-surface) temperature in recent decades due to higher levels of greenhouse gases, and the projected worsening of this effect over time.
Industry:Natural environment
The greenhouse effect keeps the earth's average temperature at around 14°C. Without it, the planet would be too cold to support human life. Greenhouse gases in the atmosphere raise the earth's temperature by trapping energy from the sun after it has hit the earth's surface, rather than allowing it to escape back into space.
Industry:Natural environment
Natural and industrial gases that trap heat from the Earth and warm the surface. The Kyoto Protocol restricts emissions of six greenhouse gases: natural (carbon dioxide, nitrous oxide, and methane) and industrial (perfluorocarbons, hydrofluorocarbons, and sulphur hexafluoride).

Inert gases are those, including helium and neon, that are not normally chemically reactive. The inert gases argon and krypton are often used in sealed double glazing units because they don't conduct heat as well as air, so they provide better insulation.

A kilowatt-hour is an amount of energy equivalent to a power of one kilowatt (a thousand watts) running for one hour. The unit is commonly used on electricity meters. If you know how many kilowatt-hours of energy your household uses, you can translate this into kilograms of CO2 emitted by multiplying it by 0.527. A megawatt hour (MWh) is an amount of energy equivalent to the power of one megawatt (a million watts) running for one hour. Similarly, a gigawatt hour (GWh) is a billion watts for one hour, and a terawatt hour (TWh) is a trillion. While your domestic gas bill will be set out in kWh, the output for a power station, for example, will obviously be expressed in one of these much larger units.
