  • Activity branch
Concepts
  • ECONOMIC ACTIVITY:  Combination of resources such as labour, raw materials, equipment, etc., are joined, leading to the creation of specific goods or services. Regardless of the factors of production integrating the good or service produced, all activities generically imply an input of products (goods or services), a production process and an output of products (goods or services).
  • REFERENCE PERIOD:  Period to which the information refers and which may be a specific day or a time interval (month, fiscal year, calendar year, among others).
  • POTENTIAL ACID EQUIVALENT INDEX - ACIDIFICATION INDEX (PAE):  Measure the potential for acid rain incidence and it`s expressed in number of H+ moles per unit of gas emitted.
Formule (Emissions of nitrogen oxides (Base 2000 - t NO2-equivalents) x 1/46) + (Emissions of sulphur oxides (Base 2000 - t SO2-equivalents) x 1/32) + (Emissions of ammonia (Base 2000 - t) x 1/17)
Measure unit (symbol) Mole/ Tonne (Mol/ t)
