aspects, and is the focus of a lot of work and investment. Improved operations, by implementing precision

aviation systems, changing routes in consensus with all of the parties involved in aviation activity, updating

the Web-Track application, which is accessible through the Aena website, in order to offer reliable and

of 25

transparent information on operations and associated noise levels, and actions to control and monitor routes,

are all essential to minimizing the effects of our activity on the environment.

Lastly, we note that this report is intended to make available to users, clients and employees the information

on the environmental performance of the Adolfo Suárez Madrid-Barajas Airport for the year 2016, so as to

complement the information that is published annually on its public website.

3. Integrated Quality and Environmental Management System

The Adolfo Suárez Madrid-Barajas Airport has had an ISO 14001:2004 certified Environmental Management

System since the year 2000. The environmental management has evolved at the corporate level, resulting in

its inclusion in the Integrated Management System (IMS), which also incorporates quality management, as

per the UNE-EN ISO 9001:2008 Standard.

In 2011, Aena adopted the environmental and energy principles that were ratified by the Aena Committee in

September of 2011. The most recent version of Aena’s policy was approved in November 2016 and is

presented below:

3.1. Aena’s Integrated Quality, Environmental and Energy Efficiency Management Policy

4. Environmental aspects

The Adolfo Suárez Madrid-Barajas Airport identifies and monitors the environmental aspects associated with

its activity so as to minimize their potential impact.

Below is a brief summary of the prevention and monitoring activities applied in each case and the results for

the 2016 calendar year.

4.1. Noise

The Environmental Department takes the following steps to ensure that the specified noise limits are

complied with:

Monitoring of operations to detect possible violations of established procedures.

Noise controls using a noise monitoring system that takes sound readings in affected municipalities

around the airport.

Reporting and engaging with the parties involved in aviation activities.

4.1.2. Measures to minimize noise pollution

A brief description of the measures implemented at the airport to minimize noise pollution is provided below:

of 25

1. Preferred runways and routes

Preferred runways and routes are used for noise abatement so as to separate the initial and final flight paths.

This includes the use of turns to move airplanes away from noise sensitive areas.

In the South configuration, the nighttime period is in effect from 11 pm to 9 am LT on Friday and Saturday

nights, whenever allowed by operating circumstances. Standard instrument departures (SID) for the daytime

period must be used for their assigned times.

2. Threshold displacement

The modification to the runway threshold is maintained, thus increasing the flyover altitude over towns near

the airport and reducing the noise levels in said towns, as required by the Aeronautical Information

Publication (AIP) and the Action Plan. Airport noise easements.

3. Noise abatement procedures during takeoff

Aircraft cannot leave a standard instrument departure before reaching a flight level of 10000 ft. The use of

flight paths is limited to certain aircraft whose noise levels are higher than the rest. Moreover, noise

abatement departure procedures (NADP) are also applied.

4. Noise abatement procedures during landing

In normal weather conditions, approach and landing operations are carried out at an angle equal to or

greater than that defined by the GP of the ILS or PAPI for each runway.

Landings on 18R must intercept the ILS in a minimum flaps and gear-up configuration until 5 DMEILS, as

long as operational safety can be maintained at all times.

5. Implementation of continuous descent approaches (CDA)

Continuous descent approaches (CDA) have been in use since 2010, replacing the stairstep approaches,

which have a higher acoustic impact due to the change in engine thrust.

6. APU usage restrictions

The prohibition on using the airplane’s Auxiliary Power Unit (APU) in certain parking stands is maintained,

requiring instead the use of 400-Hz electricity supplied through mobile units or permanent connections on

the jet bridge.

7. Restrictions on engine testing

Engines cannot be tested above idle thrust outside designated times and/or areas.

8. Prohibition to use reverse thrust

Reverse thrust cannot be used above idle thrust on certain runways at certain times, except for safety

reasons.

of 25

9. Noise fees and quotas

Penalties are applied to the landing fee for those aircraft that exceed the acoustic certification limits in place,

which are based on International Civil Aviation Organization Annex 16. Moreover, each airline has a total

noise quota assigned for carrying out its operations that is based on the effective perceived and certified

noise level.

10. Prohibition on training and test flights.

No training or testing flights may be conducted in any configuration. No aircraft that is not in radio contact

may enter the aerodrome.

11. General taxi, movement and parking procedure

Engines cannot be started up above idle thrust until the aircraft is lined up in the taxiway. Also, reverse thrust

cannot be used to leave a parking stand that normally requires pushback with a tractor.

12. Flight path tracking and compliance

The noise monitoring system (SIRMA) at the Madrid-Barajas Airport is used to check for compliance with the

noise abatement routes and procedures in place at the airport and to identify potential violations.

13. Reduced operations of ICAO Chapter II aircraft

Since 2002, all operations involving aircraft certified under Chapter 2 of Annex 16, Vol. 1, Part 2, of the

International Civil Aviation Organization have been prohibited.

14. Restrictions on marginally compliant aircraft

Operations involving aircraft that exceed the limit certification values in Vol. 1, Part 2, Chapter 3, Annex 16 of

the International Civil Aviation Organization by an aggregate margin of 5 EPNdB (effective perceived noise in

decibels) are prohibited.

15. Restriction of aircraft movements during nighttime period in parking stands on R-5, R-6 and the

South Dock.

Movements on R-5, R-6 and the South Dock are prohibited from 11 pm to 7 am LT.

4.2. Atmosphere

4.2.1. Carbon Footprint

For the fifth year in a row, the Adolfo Suárez Madrid-Barajas Airport prepared a greenhouse gas (GHG)

emissions report to determine the carbon footprint associated with its activity so as to maintain its

certification in ACI Europe’s Airport Carbon Accreditation Program. This is a voluntary program with 190

member airports, 116 of them in European countries (Illustration 1).

of 25

The requirements used to carry out and verify the inventory, as well as to write the associated reports, are

contained in ISO 14064 “Greenhouse Gases”. This standard details the principles and requirements for

organizations of all kinds to design, develop and manage GHG inventories.

Airport Carbon Accreditation Program

Illustration 1. Airports in the program Source: http://www.airportcarbonaccredited.org/

On 18 June 2008, via a resolution on climate change, ACI Europe (Airports Council International, European

Region) committed to helping airports evaluate and reduce their carbon footprints. To this end, this

organization, along with WSP Environmental, created “Airport Carbon Accreditation” (ACA), a voluntary

accreditation system for airports that promotes and allows for the implementation of management processes

to reduce emissions associated with airport operations.

In 2012, the Adolfo Suárez Madrid-Barajas Airport reached Level 2: “Reduction”, a level that recognizes the

airport’s efforts to manage and reduce its CO2 emissions by mapping and monitoring its carbon footprint and

establishing reduction measures (Illustration 12).

The airports of Adolfo Suárez Madrid-Barajas, Barcelona-El Prat and Palma de Mallorca are the only

Spanish airports that are accredited in the Airport Carbon Accreditation at this level.

The year 2016 saw a reduction in CO2 emissions with respect to 2015 due to the emission factor used for the

calculation and to the energy saving activities implemented.

Emission factor used: In 2016, the factor published by Red Eléctrica de España was 0.214

kgCO2/kWh, as compared to the one published for 2015: 0.266 kgCO2/kWh.

Energy saving initiatives carried out in 2016: installation of LED technology in HVAC rooms, P1

baggage sorting area, replacement of lights on runway 36L, P2 photovoltaic installation and

replacement of lights in hall 1 of T1.

This yielded a total savings of 13,344.20 TCO2, which is equivalent to a 12.41% reduction with respect to the

previous year.

As the table below shows, the emissions/passenger ratio fell considerably in 2016, remaining below the

average for the past three years.

4.2.2. Air Quality in the Airport Complex

The air quality in and around the airport is monitored using a system that constantly measures the air

pollution. The system is called REDAIR (Air Quality Monitoring Network), and it is used to determine the

concentrations of the main pollutants produced as a result of the airport’s activity.

Particulate matter (PM10 and PM2.5).

Nitrogen dioxide / Nitrogen oxides

(NO2/NOx)

Ozone - (O3)

Sulfur dioxide – (SO2)

Total hydrocarbons (methane and non-

methane).

Lead (Pb).

Benzene (C6H6).

Carbon monoxide (CO).

The Air Quality Monitoring Network consists of three fixed stations and one mobile laboratory. The

purpose of these stations is to constantly and automatically monitor the air quality in areas affected by airport

operations (takeoff, landing and taxi) in order to determine the level of compliance with the limits specified in

the applicable law.

The locations of these stations, agreed to with the Ministry of the Environment and the Madrid regional

government, are shown in the map provided below. The locations of two REDAIR stations were modified this

past year:

of 25

Redair 3: Moved on 31 August 2016. It was relocated from the vicinity of the South Dock, across from

the R5-R6 apron, to its new location in the “T-4 Satellite Terminal Firefighting Service Building”.

SATELLITE FFS

Mobile Laboratory: Moved on 20 December 2016. Moved from its original location in the “T-4

Satellite Terminal Firefighting Service Building” (SATELLITE FFS), where it had been since 18 May

2010, to UTM X coordinates 453602.06 andUTM Y 4479007.88.

The data obtained in 2016 show that the main pollutants in the air quality monitoring network of the Madrid-

Barajas Airport were nitrogen dioxide (NO2), particulate matter (PM10) and ozone (O3).

Over the course of 2016, however, there was a slight to moderate downward trend for NO2 and PM10.

Reaching a general conclusion on the sources of the various pollutants analyzed is not simple, but the

concentrations of NO2 in the networks of both the region and city of Madrid exhibit the same trend as in the

REDAIR network, which may lead to the conclusion that the generalized presence of this pollutant is similar

throughout the region of Madrid.

Considering how one of the main emission sources for these two pollutants is road traffic, how the airport is

bounded by the A-2, M-14, M-11 and M-50 highways (see map Illustration 3) and how no relationship has

been found between pollution levels and the number of aircraft arrivals and departures, it may be concluded

that the levels of NO2and PM10 detected in the REDAIR stations of the Adolfo Suárez Madrid-Barajas Airport

are due primarily to road traffic.

It should be noted that REDAIR station 3 had been in the area that is most affected by nearby road traffic

until 31 August 2016.

As for ozone, no violations of the alert threshold were recorded at any of the REDAIR stations in 2016.

The map below shows the locations of the REDAIR stations.

4.3. Soil

4.3.1. Actions

The monitoring network defined by the airport’s Environmental Department in the “Action Plan for 1 July

2014 to 30 June 2018. Maintenance and Comprehensive Monitoring Service for Soil and Groundwater at the

Adolfo Suárez Madrid-Barajas Airport”, consists of

308 piezometers associated with the hydrocarbon (HC) plume monitoring activities and tracking of

piezometric levels of other systems to monitor soil quality.

The following activities were carried out in 2016:

Activities to intercept and extract hydrocarbons, associated with fuel storage and distribution actions.

Campaigns to monitor the quality of groundwater.

Campaigns to monitor the quality of interstitial air.

Start of work to expand the airport’s network of piezometers.

4.4. Water

4.4.1. Water quality

The quality of the water in the bodies of water that run through the airport, as well as of the water discharged

into them as a result of its activities, is monitored through annual samples (Water Control Program) that

collect water from surface, rain water, underground and wastewater sample points. All of the samples are

taken and tested under a water analysis and quality control service contract that is awarded to an accredited

partner agency of the water authority for the purposes of water quality monitoring and control. This agency is

duly accredited to take and test the required samples.

4.4.2. Rain water

The airport has 16 units for treating rain water: 10 oil-water separators (OWS) and 6 desanders. One unit is

located at each of the 16 discharge points authorized by the Tajo Water Authority (CHT).

The quality of the rain water discharged to a public body of water is analyzed every six months. The results

of the physical/chemical analyses are compared to the limits imposed by the Tajo Water Authority in the

associated discharge permit.

In 2016, the analysis values for suspended solids (SS) and hydrocarbons (HC) were below those specified in

said Discharge Permit (Table 5).

4.4.3. Wastewater monitoring

The household, urban and industrial wastewater generated in the airport’s various buildings and facilities are

routed into the airport’s sewage system and sent to the municipal sewage network (Barajas Integrated

Sewage System).

The airport has nine points for discharging wastewater: Barajas, Airside Powerplant (CELA) - Control Tower

(TWR), T4 Satellite, T4 South, T4 North, End of line for terminals T1, T2&T3, Modular Cargo Zone, Iberia

MET-MASA Zone and Technology Systems Lot.

In order to comply with the legal requirements in terms of the maximum discharge parameter values

specified in Decree 57/2005 of the Region of Madrid, the airport monitors the activities of Aena as well as of

its concessionaires by taking readings at the nine wastewater discharge points:

Annual checks: “Technology Systems Lot” discharge point, which includes the wastewater from the

waste transfer plant, the cogeneration plant, the aircraft sewage treatment plant and the airport’s

number 1 powerplant.

Monthly checks: sampling at the Barajas, T4 Satellite, End of line for terminals T123, the modular

cargo zone, and the Barajas and Iberia MET MASA points.

of 25

Quarterly checks: sampling at the four discharge points in the airport expansion area: T4 South, T4

North, CELA-TWR.

The total nitrogen levels in the terminals were exceeded in 2016 due to the nature of the discharge

(bathroom water). Hydrocarbon and grease readings were also exceeded, mainly at the end of the line for

terminals T123. Actions are being taken to resolve this problem by improving the discharge conditions.

4.4.4. Surface water. Streams and lagoon.

A chemical/physical analysis of the water in the airport lagoon and upstream and downstream of the

Valdebebas, Zorreras and La Vega streams is done every six months. All of the sample points analyzed in

2016 satisfy the quality targets specified in the Tajo Water Plan for this segment of the Jarama River basin,

with the exception of the La Vega and Zorreras streams, which receive discharges from treatment stations,

meaning they enter the airport with a high pollutant load, primarily nitrogen. As a result, their status as they

flow through the airport is tracked to verify that the pollutant load decreases. This way it can be shown that

the airport does not contribute to polluting these streams.

4.5. Waste

The Adolfo Suárez Madrid-Barajas Airport generates a considerable amount of waste, both hazardous and

non-hazardous, due to the constant passenger traffic and to all of the activities that take place there.

The airport’s priorities in terms of handling the waste generated are: optimize, reduce, promote best

practices among employees, ensure the waste is properly sorted, stored and managed and track the waste

generated by the companies that operate at the airport through the Environmental Monitoring of Companies

Service (SERCOM).

In order to ensure that the waste is correctly handled and sorted, the airport has ten public waste collection

points, a waste transfer plant, a waste triage plant and twenty private collection points for companies that are

regarded as large waste producers.

4.5.1. Hazardous Waste

In 2016, the amount of hazardous waste (HW) generated at the airport fell considerably due to the spike in

2015 caused by the amount of fiber cement generated by cleaning activities in the area of La Cuña. The year

2016 saw a total of 176.10 tons of HW generated, versus the 270.05 generated in 2015 (Table 6).

Last year, 47.75 tons of lead batteries were processed due to the periodic removal of batteries from the

UPS’s, which accounted for over 25% of the HW generated in 2016.

As well as lowering the amount of HW generated, the airport also managed to increase the amount of HW

that was recovered with respect to the previous year, going from 20.91% in 2015 to 39.11% in 2016 (Table 6

and Graph 2).

4.5.2. Non-hazardous waste

The amount of non-hazardous waste (NHW) generated at the airport has been on the rise since 2014. This

trend is directly related to the increase in the number of passengers handled in recent years. If we relate the

generation of NHW to the number of passengers, we see a drop in the ratio of kg NHW/passenger (Table 7

and Graph 3):

4.6.3. Electricity usage

The increase in electricity use is due to the rise in passenger traffic and operations at the airport (Table10

and Graph 6). As we can see, the kWh/passenger ratio shows a downward trend. These results are

indicative of the efforts made at the airport to reduce its electricity use and the emissions associated with it.

4.7. Biodiversity

4.7.1. Vegetation

According to the map of potential vegetation (Rivas Martínez, 1987), the potential vegetation in the study

area at the Adolfo Suárez Madrid-Barajas Airport is:

Oak groves with meso-Mediterranean dry and basophylous series of the Bupleurorigidi -

Quercetorotundifoliae holm oaks and supra-Mediterranean silicicole of the Juniperusoxycedri-

Quercetorotundifoliae holm oak.

of 25

Riverbank forests of Mediterranean and irrigation riparian geomegaseries.

The natural plant formations that can be found at the airport, then, are as follows:

Meadows. Consisting of formations that colonize already altered lands. At the airport they occupy

most of the areas of natural vegetation (Illustration 4).

Illustration 4: Examples of meadows at the Adolfo Suárez Madrid-Barajas Airport Source: Compiled internally.

There are two types of meadows:

- Nitrophilous meadows of thero-brometalia that formed over abandoned cropland. In them we

find legumes of the Medicago, Trifolium and Astragalus genera, and poaceae of the Aegilops,

Bromus and Dactylis genera.

In some areas of the airport, these nitrophilous meadows support a layer of scattered trees.

The main species to be found are the black poplar (Populusnigra) and elm (Ulmuspumila)

trees.

- There are also ruderal meadows formerly used for farming. Growing in them are species of the

Carthamus genus, cruciferae of the Sinapis genus, leguminosae of the Trifolium, Medicago,

Astragalus and Vicia genera and poaceae of the Avena, Bromus, Hordeumand Poa genera.

Shrubs. Formation consisting of flowering plants located primarily at the north side of the airport

complex. They are found as small formations of plants of the Genistoscorpii-Retametum grouping

in areas that have regenerated on land formerly used for crops. In addition to

Retamasphaerocarp, there are bramble bushes of the Rubusgenus and numerous herbaceous

species.

of 25

Repopulated pine groves.There are dense areas of stone pine (Pinuspinea) and Aleppo pine

(Pinushalepensis) that in some parts are mixed in with Arizona cypresses. They lack a woody

sublayer and grasses are very scarce (Illustration 5).

Illustration 5: Repopulated pine groves. Source: Compiled internally.

Riparian forests. Located near the La Vega and Zorreras streams and in the vicinity of the

Jarama River. There are fairly well defined ash groves in some sections of the Zorreras stream,

with ash (Fraxinusangustifolia) as the dominant species and elm (Ulmussp) as a typical tree

(Illustration 6). Along the Jarama River there are groves with willow (Salix sp) and black poplar

(Populusnigra) trees and other species like hawthorn (Crataegussp).

Illustration 6: Riparian forests. Source: Compiled internally.

Reeds. These are found along sections of the streams and in the seasonal lagoons. The main

species are cattail (Typha sp.) and common reed (Phragmites sp.).

4.7.2. Fauna

The presence of wildlife in the airport complex poses a problem to operational safety. Birds in particular pose

a potential threat to aircraft, and can cause anything from minor damage to serious accidents.

In order to regulate the presence of wildlife in the airport and ensure the safety of airport operations, a series

of preventive measures is carried out in concert with the relevant authorities that vary depending on the time

of year and the species.

The airport has had a Wildlife Control Service (WCS) since 1970. Its main function is to deter the presence of

birds through various means, such as by recreating dangerous conditions for birds, neutralizing possible

factors that may appeal to birds and diverting movement patterns so as to keep the most dangerous species

away from the runways.

In addition to these activities on the runways, the WCS carries out other tasks intended to reduce the

population of dangerous wildlife in and around the airport complex. The actions taken are designed to

manage the existing habitats at the airport so as to keep them from providing shelter to various wildlife

species.

The following actions were taken in 2016:

Measures intended to manage habitats

Mowing of grassy areas to limit their height.

Control of the height of grasses around the runways by applying herbicides.

Cleaning landscaping waste.

Removal of the remains of small mammals, birds, etc.

Comprehensive monitoring and control of insects (wetlands, dry areas, forests).

Maintenance of vegetation cover.

Measures intended to drive away wildlife

Biological controls by way of birds of prey (falconry).

Use of pyrotechnics.

Other devices: warning calls, siren.

Measures intended to keep out wildlife

Checks of the perimeter enclosure and safety fence.

Placement of anti-nesting and anti-perching devices.

Removal of perches.

Measures for capturing wildlife

Capture in traps using birds of prey: snares, nets, cages.

Location and removal of nests outside breeding season.

of 25

Removal of chicks and eggs from nests (in concert with regional forest rangers).

Management of roosting places.

Control of pigeon populations.

Population control of prey species (lagomorphs) inside airport complex with shotguns, ferrets and

nets.

Population control of boar using traps/cages and sweeps.

Capture of mammals using snares, nets and cages.

Other measures

Tracking of wildlife populations.

Tracking of nests.

Identification of areas of interest to wildlife.

Identification of species involved in collisions.

Identification and control of nests.

Cooperation with neighboring hunting preserves.

Study to identify areas with a high number of rabbit holes.

Testing of new plant covers that are unappealing to wildlife.

Implementation and monitoring of the Program to Manage Risks Associated with Wildlife.

5. Aena Environmental Office

5.1. Complaints and information requests received and analyzed

Aena has an Environmental Office for handling environmental issues (available through its website at the

following link http://www.aena.es/es/corporativa/oficina-atencion-ambiental.html), as well as an office specific

to the Madrid-Barajas Airport (OFIMA), intended exclusively to process, record, handle and reply to queries

of an environmental nature.

In 2016, a total of 1,837 complaints and information requests were received from 205 individuals through the

various channels in place.

This was far lower than the number of complaints received the previous year. The trend with respect to 2015

and 2014 is shown in the graph below Graph 8.

6.2. World Environment Day

As it does every year, the Madrid-Barajas Airport observed World Environment Day, which is celebrated on 5

June every year in over 100 countries around the world.

On this occasion, the Environmental Department organized the following activities:

Presentation of corporate environmental competition awards

Public exhibit “The Airport cares for the Environment”

Presentation of awards in the “Adivina” (Guess) contest.

7. Environmental awards and distinctions

7.1. Ministry of the Environment’s Carbon Footprint Registry.

In 2016 the airport renewed its registration in the Spanish Ministry of the Environment’s Carbon Footprint,

Carbon Dioxide Offset and Absorption Registry. This is voluntary registry, governed by Royal Decree

163/2014, which was created to encourage Spanish organizations to calculate and reduce their carbon

footprint.

Through this registry, the Adolfo Suárez Madrid-Barajas Airport reaffirms its commitment to respecting and

preserving the environment.

The goal in coming years will be to further its reduction efforts and recognize the steps taken by the airport to

not only calculate its emissions, but to establish measures to reduce them.
