Greenhouse efect

Phenomenon by which certain gases that make up the atmosphere retain part of the energy from solar radiation emitted by the ground, causing a moderation of temperature variations of the earth and an increase in its average temperature. This phenomenon is being intensifed by the emission of certain gases in large quantities, such as CO

2

and methane, caused by human activity.

Greenhouse Gas Protocol

International instrument used by government and companies to record and manage their greenhouse gas emissions. This initiative was created by the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute.

Greenhouse gases

Compounds that are found in the atmosphere and which, due to their properties, are responsible for

the greenhouse efect. The massive emission of these gases through activities such as the burning of fossil fuels increases the greenhouse efect; this increase is recognized as the leading cause of global climate change. Among these substances the following ones are included: CO

2

, CH

4

(methane), N

2

O, HFCs, PFCs, SF

and water vapour.

GRI (Global Reporting Initiative)

These guidelines, to be used on a voluntary basis by organisations, exist for the purpose of improving the quality of their reports and achieving greater comparability, consistency and efciency in their dissemination.

GRP (Gross Rating Point)

The basic rating point is the unit of measureof advertising efectiveness. It consists of the percentage of the audience that viewed a given television spot compared to the potential market determined previously between the television operator and the advertiser/media centre. Data that is later contrasted with the data provided by Taylor Nelson Sofres. GRP are measured per minute, although the advertising spots tend to have a shorter duration. GRP can also be calculated by multiplying the net coverage by the frequency of a spot.

Incidence index

Ratio of occupational accidents to the average number of workers exposed to the risk. This index indicates, therefore, the probability of an occupational accident occurring to the staf.
