Reduction of GGE

 Emissions avoided

  • Airports Energy consumption in permanent facilities at BAA airports is measured and objectives are established for reducing consumption with a view to increasing efficiency. Energy consumption forecasts are used to plan energy cost budgets in facilities. All efforts are focussed on reducing unnecessary energy costs and reducing waste generation although there are also examples of investments aimed at improving energy efficiency.

    In the airports, small-scale examples of renewable energy sources can be found, such as the use of photovoltaic panels for lighting car parks.

    In the new Terminal 5, indoor heating and air conditioning will use an energy efficient system. Use will be made of residual heat obtained by a cogeneration process to meet 85% of heating requirements. It is estimated that 1,100 tons of CO2 will be saved as a result of this measure.

    Furthermore, the air conditioning water is supplied from units that use ammonia and do not produce CO2 and the lights are adjusted depending on requirements. 70% of the water used by the terminal comes from rainwater or subsoil and not from ordinary water systems, with recycling of up to 85% of the rain that falls on the terminal perimeter.

  • Waste management. There has been a 23% reduction in emissions in Hazardous Waste treatment centres (excluding incineration plants) up to 193.08 Teq CO2. This reduction is due to the reduction in the entry of these substances to hazardous waste treatment plants. In incineration plants, emissions have increased slightly from 40,431 Teq CO2 to 42,419 Teq CO2 as a result of the increase in the number of tons incinerated. The emission of 328,099 Teq CO2 was avoided as a result of the sorting activity in the municipal waste management plants which was 36.58% more than in the previous year due to the opening of 7 new plants.

  • Toll roads In toll roads, all Spanish and Portuguese concession company emergency telephones now work with solar power obtained from panels.

  • Car parks In on-street parking areas, Cintra has continued with its policy of installing ticket meters powered with solar panels. In 2007 Cintra made a study of lighting systems in car parks which led to electricity consumption being minimised in this facilities.
