Emissions, effluents, and waste


The SyV Group’s main greenhouse gas emissions can be classified as follows:

- Direct emissions arising from fuel combustion to generate energy.

- Direct emissions arising from fuel consumed to drive machinery, vehicles, and ancillary systems such as generators and temporary facilities (concrete and crushing plants), diesel and gas boilers, etc.. These emissions come from sources owned or controlled by the Group.

- Indirect emissions arising from the generation of power purchased and consumed by the Group. These emissions occur physically at the specific plant where the power is originally generated, i.e., the emissions do not arise in the course of the SyV Group’s actual activities.

Emisiones directas derivadas del consumo de combustible

Sacyr Vallehermoso has both combustion installations that fall within the scope of Council Directive 96/61/EC of 24 September 1996 concerning integrated pollution prevention and control (IPPC) –which are obliged to report data to the European Pollutant Release and Transfer Register (PRTR)- and those that, while not included in the Directive, voluntarily calculate their emissions.

Total emissions at Valoriza Energía’s installations are calculated based on the guidance document for reporting emissions at thermal power stations and other combustion installations. Emissions of the installations within the scope of the IPPC Directive are made public as specified in EC regulations concerning the establishment of a European Pollutant Release and Transfer Register.

Continuous measuring equipment for combustion gases (NOX and CO) are available in the chimneys of the biomass boilers.

With the entry into force of the Kyoto Protocol, Spanish companies included in the National Allocation Plan (NAP) have the responsibility and obligation to ensure that their emissions are controlled efficiently and comply with the limits established in prevailing legislation.


A decrease in grammes of CO2/kwh generated due to the start-up in 2011 of Biolinares, a biomass combustion facility which was opened in May 2010. This lowered the CO2 / kWh ratio in 2011 vs. 2010 by 1.68%.
