For monitoring purposes, environmental sustainability is measured through indicators on energy , water , wastewater , and solid waste management, CO2 emissions, mobility, and air quailty and noise.
ENERGY MANAGEMENT
Daily energy consumption of tourists vs. daily energy consumption of resident population
Establishments that optimise energy consumption
Percentage energy consumption produced by renewable sources vs. total energy consumption
WATER MANAGEMENT
Daily water consumption by tourists, relative to daily water consumption by the resident population
Establishments that optimise water consumption
Percentage of tourist companies using recycled water
WASTEWATER MANAGEMENT
Percentage of sewage treated prior to discharge
SOLID WASTE MANAGEMENT
Establishments that separate waste
Daily waste production by tourists, vs. daily waste production by resident population (Kg)
CO2 Emissions
Percentage of tourist companies involved in climate change mitigation activities – such as reducing CO2 emissions, low energy consumption systems, etc. – and “adaptation” responses and actions
Mobility
Number of passengers embarked and disembarked from cruise ships at the Port of Portimão
Air quality and noise
Air quality index
