Diagnostic study

The measurement of the carbon footprints is carried out on the basis of the analysis of each of the key sectors in the territories:

Houses which make up the residential sector of the cities; the main emissions sources from this sector are the use of electricity and natural gas in homes. This sector also has a high level of water consumption and generation of waste water.

The industrial sector is made up of several subsectors such as tanneries, textiles, drinks, amongst others that generate products and hence consume significant levels of water, energy and fuels (especially LPG and diesel).

This sector consists of installations dedicated to commercial activities and government and municipal institutions, so it has a high demand for water, energy and fuels (especially LPG).

This sector takes into account the consumption of fuels such as petrol, diesel, NGV, LPG, and even electricity, by both private vehicles and public transport in the cities.

This sector includes solid waste disposal activities and waste water treatment in the cities.
