Ferrovial - Integrated annual report 2013 / Feedback from analysts

Ferrovial was recognized by the CDP for its climate change strategy. It was included in the Climate Disclosure Leadership Index and Climate Performance Leadership Index, which ranks companies with best practices for reducing emissions and mitigating the effects of climate change. Ferrovial has achieved a score of 99 points out of 100 and maintains the maximum A category. The company has been present in these indices since 2009.

 In addition, Ferrovial has achieved a leading position in the first Supplier Climate Performance Leadership Index (SCPLI) prepared by the CDP. This index accredits the excellence of companies as suppliers of products and services that have business models low in carbon emissions.

CDP is the only global corporate environmental information system in the world. It is an international non-profit organization that offers a system for companies and cities to measure, disclose, manage and share relevant environmental information. It works with market agents, including 722 institutional investors managing assets of 87 trillion dollars, to motivate companies to publish their impact on the environment and natural resources and to take measures to reduce them.

The Dow Jones Sustainability Index and FTSE4Good Index have also recognized Ferrovial’s climate strategy and carbon footprint management.

Case study

Clima Project

The Spanish Climate Change Office (OECC) has selected the Climate Project “Plant for Processing Solid Urban Waste into bioliquid similar to Diesel C” presented by Ferrovial Servicios in the call for proposals for 2013. The OECC thus supports and promotes low-carbon activities through the acquisition of verified reductions in emissions generated.

The Clima Project selected consists of the installation of technology to recover 16,000 tons per year in biomass and plastic waste from the waste classification and composting plant of Mancomunidad Comsermancha. This processing plant uses processed waste, i.e. waste previously subjected to processes of characterization, selection, selective sorting, elimination of metals and contaminants and processes of grinding and refining, as raw material. The main product resulting is a bioliquid fuel similar to diesel “C”, thus minimizing the impact of human activity on ecosystems, and considerably reducing the carbon footprint as well as the environmental footprint of materials and waste. The SRF (solid recovered fuel) comes from:

  • Biomass from the organic part of urban waste. It accounts for 60% of the SRF to be used. This biomass is mainly made up of cardboard, wood and vegetable waste, remains of food, cellulose and other organic materials.
  • Mixture of plastics from urban waste. Makes up 40% of the SRF to be used. This mixture is made up of various packaging plastics used and other plastic materials from post-consumer objects.

The dumping of biomass included in SRF in a landfill would lead to its anaerobic fermentation and thus the emission of CO2, CH4 and N2O. At the same time, obtaining the bioliquid similar to diesel “C”, reduces the consumption of fossil fuels and the consequent emissions of these gases derived from the process of their production and combustion. To sum up, the development of this technology leads to numerous environmental objectives, among them the following:

  • Reduction of greenhouse gas emissions.
  • Saving in fossil fuels for future generations.
  • Recovery of energy in materials destined for the landfill.
  • Reduction in the volume of waste destined for the landfill and thus increase in the useful life of landfill containers.
  • Reduction of investment for establishing and managing new landfill containers.
  • Reduction of methane gas emissions derived from landfills.
  • Generation of a local industry with high technological value.
  • Reduction of energy costs and energy diversification in the country.

An annual average reduction of 7,277.92 t CO2 eq. has been calculated, of which 6,223 t CO2 eq. come from the replacement of diesel C and 1,236 t CO2 eq. from waste not dumped in landfills.

A total of 109,168.8 t CO2 eq. will be cut over the useful life of the plant.
