GPS
Global positioning system. A system that calculates the current location on the Earth (latitude and longitude) of a radio wave receiver using information obtained from 24 orbiting satellites. GPS is used in applications such as car navigation systems.
GWP
Global warming potential. Indicates the impact on global warming as a ratio of CO₂.
Global warming
Global warming is the phenomenon whereby the average temperature of the Earth is rising due to increases in the amounts of greenhouse gases such as CO₂ in the atmosphere. It is predicted that if this situation continues, the average temperature of the Earth will rise by 2 degrees by the end of the 21st century. There is great concern that global warming will lead to the destruction of ecosystems due to sudden temperature changes and weather anomalies such as heavy rain, drought, and extreme heat, as well as the submersion of low-lying regions due to rising sea levels.
Green certification
To certify a supplier who meets the required conditions as a source of green procurement.
Green procurement
This means to prioritize procurement of materials with low impact on the environment with the aim of promoting the development of environmentally sound products and raising the environmental awareness of designers and developers
Green purchasing
This means to consider carefully the necessity of a product or service before purchasing it, and to place purchasing priority not only on the price and quality, but also on the impact that a product or service has on the environment.
Greenhouse gases (substances that cause global warming)
Also known as global-warming gases, these substances absorb infrared rays from the Earth's surface. Typical examples are CO₂ and methane. The Earth's surface is warmed by heat from the sun. Most of this heat, in the form of infrared rays, then escapes into space. But some infrared rays are absorbed by greenhouse gases. So not all the heat escapes. Although an appropriate amount of greenhouse gases is indispensable, an excessive amount of such gases in the atmosphere leads to global warming.
