4.8 Eco-efficiency

Land use (A_29)

The percentage of the service area occupied by the company’s own or leased active facilities (8,199,546 m^²) is 45.96% of the total area (17,841,824 m^²), although if we consider the 7,382,473 m^²of usable area (excluding the 10,459,351 m^²of marshland), the percentage would be 41.38% of this area.

Water consumption (A_30)

Management of the Port’s water supply network, whose consumption points are 100% monitored, is outsourced to the municipal water company Aguas de Huelva, which is responsible for selling water within the Port.

The trend over the last three years in the Port Authority’s total annual water consumption, expressed as total cubic metres and as cubic metres per square metre of the Service Area, is as follows:

Port Authority water consumption by use in 2025:

Huelva Port Authority has installed meters to gain a better understanding of consumption by application and to detect leaks as a cost-saving measure.

Evolution, at least in the last three years, of the efficiency of the water distribution network, expressed as a percentage, for those Port Authorities that directly manage the water distribution network (A_31)

It is important to highlight the significant efforts made by Huelva Port Authority to prevent potential water wastage. The following shows the trend over the last three years:

Electricity consumption (A_32)

Electricity is distributed in the Port of Huelva via the various infrastructure networks belonging to ENDESA Distribución. Since 1 July 2009, pursuant to Decree-Law 485/2009 of 3 April, operators carrying out their activities within the service area of Huelva Port Authority have been able to contract the purchase of electricity from the supplier best suited to their needs from among those present in the market.

The trend over the last three years in total annual electricity consumption at Port Authority facilities and in the lighting of common areas, expressed as total kWh and as total kWh per square metre of the Service Area, is as follows:

Port Authority electricity consumption by use in 2025:

As a control and savings initiative, it is worth highlighting the continued development in 2025 of the energy efficiency project that has been underway since 2019. Furthermore, the APH has been sourcing its electricity from a supplier with a 100% renewable energy mix, contributing to a 100% reduction in CO2 emissions from the Main Office.

It should be noted that there are new facilities in use (such as the Fish Market, Ciudad del Marisco, and the Multifunctional Building), as well as shared port areas, which have increased energy consumption compared to previous years.

Fuel consumption (A_33)

The trend over the last three years in the total annual fuel consumption by Huelva Port Authority, expressed as total cubic metres and as cubic metres per square metre of Service Area, is as follows:

Throughout 2025, the focus remained on energy efficiency measures such as optimising lighting and upgrading the vehicle fleet by replacing diesel vehicles with hybrids.
