Shakespeare Cliff
Jardins du point du jour French Terminal
This is the fifth year that Eurotunnel has published its Environment Report.
Concern for the environment was a decisive factor in the French and British Governments
choosing the Eurotunnel scheme:
- the Channel Tunnel runs entirely underground and does not interfere in any way with
the marine environment
- overground, its maintenance and operations infrastructures are fully integrated into the
- the environmental advantages of the electric traction of trains and shuttles are
undisputed: minimum atmospheric pollution, virtually no greenhouse gas emissions.
In line with the spirit of this original choice, Eurotunnel has always shown concern for the
need to respect and enhance the environment.
In 2006, in addition to confirming the requirements associating with obtaining a
Prefectoral Order to consolidate its activities requiring a permit or declaration under the
French law on facilities registered for environmental protection purposes (ICPEs),
Eurotunnel has stepped up its commitment to environmental protection through:
- continuing its global business strategy of managing electricity and water consumption
- optimising its partnership with the French environment and energy efficiency agency
- introducing formal monitoring of its emissions of greenhouse gases and ozone-depleting
- continuing the search for products to replace Halon 1301 in anticipation of loss of
Critical User status
- carrying out a review of our carbon footprint using ADEME’s own method known as
Bilan Carbone®.
The text of the French Environment Charter was adopted by the
French Parliament on 28th February 2005 and promulgated by the
French President on 1st March 2005. Eurotunnel had participated in
the wide democratic debate launched by the Ministry of Ecology and
Sustainable Development.
2006 Environment report
d Pignon
Eurotunnel is a bi-national (Anglo-French) company which has a Concession to manage
and operate the Channel Tunnel until December 2086. As a rail transport operator,
Eurotunnel operates its own Shuttles: 9 Passenger Shuttles (cars and coaches) and 16
Truck Shuttles. As an infrastructure manager, Eurotunnel ensures the safe, efficient
passage of trains belonging to various operators: passenger trains (Eurostar) and goods
trains (SNCF, EWS).
In 2006, over 2 million cars and 67,000 coaches as well as 1.3 million trucks were
carried through the Channel Tunnel. The Group employs 2,263 directly (December 2006
payroll) and its activities also create many jobs for sub-contractors.
¾ Building with conservation in mind
Fond Pignon
In France, the Fond Pignon site, an earthfill
embankment formed from 5 million cubic metres of
earth extracted by the tunnel boring machines during
construction, has been replanted by Eurotunnel and is
now a nature reserve, fully integrated into the
landscape of Cap Blanc-Nez. The site is popular with
migratory birds and ecological management has been
entrusted to the French coastal conservation authority,
the Conservatoire du Littoral.
In England, Samphire Hoe, a tract of land formed
from 5 million cubic metres of chalk extracted during
the Tunnel’s construction and added to the British
landmass, has been turned into a nature reserve
extending over 30 hectares between Dover and
Folkestone. It provides a habitat for numerous species
of plants and animals.
Skakespeare Cliff
Every effort was made to integrate the transport system and associated activities into the
landscape and protect the local environment by limiting noise pollution as far as possible.
In the consultation process between Eurotunnel, the French Government and the local
authorities at the preliminary design stage, the social, economic, environmental and
cultural aspects of sustainable development were given thorough consideration:
- environment aspect: the project should contribute to enhancing the area’s landscape
while complying with the special legislation in force to protect the coastal area
- social aspect: the area’s inhabitants should have access to the sports and cultural
facilities created and the housing being build, accepting the principle of achieving social
mix by creating a proper community
- economic aspect: the project should have a real impact on local economic development.
2006 Environment report
In France, the law on facilities registered for environmental protection purposes (ICPEs)
classifies facilities according to environmental risk (Law of 19th July 1976). Various
activities on the Coquelles Terminal and Sangatte site therefore require a permit
(cooling, repair workshops, etc.) or a declaration (storage of flammable liquids, use of
abrasive materials, paint application, etc.). These regulations do not apply to the UK
Since 1994, declarations or permit applications have been successively lodged and
consents obtained for activities as they have started.
In 2001, in the light of the changes that have occurred with some of its activities affected
by French environmental protection regulations (closing down, expansion) and the
changes in the regulations affecting registered facilities, Eurotunnel applied to consolidate
its activities to facilitate administrative monitoring. Its case had the backing of the
DRIRE, the regional authority concerned with industry, research and the environment.
After three years of preparing the case and it being considered (consultation with CHSCT
Eurotunnel’s occupational health and safety committee, public enquiry, response to
comments registered, etc.), the consolidated ICPE Prefectoral Order was obtained in
January 2006.
¾ Organisation
Environment Committee (SSEC)
Eurotunnel has set up an organisation to
manage environmental issues effectively.
The SSEC comprises three board
members, the Operations Director,
Safety and Sustainable Development
Director, Shuttle Division Director,
Maintenance Division Direction and
representatives from their divisions.
This committee meets every three
months to discuss progress on actions
2006 Environment report
Creation of a Safety and Sustainable
Development Directorate
True to its commitment to the environment,
at the beginning of 2006 Eurotunnel set up a
Safety and Sustainable Development
Directorate. Safety represents an absolute
requirement for Eurotunnel. Combining it
with a strong sustainable development policy
shows to what extent these issues are
important for the Company.
The Safety and Sustainable Development
Directorate is responsible for environmental
policy implementation and monitoring and
reports to the Chief Operating Officer.
Eurotunnel’s Environmental Management
System (EMS) is based on the requirements
and recommendations of the ISO 14001
¾ Enhanced internal communication
All employees have a role to play in our environmental initiatives: regulatory watch,
environment report, environmental assessments, action plan, reference documents and
environmental topics are all available on multimedia tools (Intranet, e-gazette, etc.).
Specific articles on the following topics were communicated to staff in 2006:
- Tips on saving energy
- Ecology: maintaining the balance between wildlife and tunnel operations
- Equipping a Eurotunnel breakdown truck with a pump to handle fuel spillages
- The new sustainable development team takes off
- Sustainable development week
- Eurotunnel and WCCP receive the green flag for Samphire Hoe
- European mobility week
¾ External relations and partnerships
Ongoing efforts to enter into a Framework Agreement with ADEME:
The meetings between Eurotunnel and ADEME, first held in 2004, have continued with a
view to defining each party’s commitments within the framework of a partnership centred
on three main subjects:
- energy saving and combating global warming
- waste reduction and prevention
- raising staff and customer awareness on sustainable development issues.
Participation in Club ISO 14001
Eurotunnel is a member of this environment club run by the local chambers of commerce
in France which provides it with an opportunity to exchange views with other local
Participation in the first environmental performance award organised by the
Nord Pas-de-Calais region’s environmental task force (Mission Environnement)
With its confidence boosted by its results, Eurotunnel submitted seven entries on
different topics:
- voluntary publication of the environment
- environmental requirements in managing
- waste management
- preventing hydrocarbon pollution
- raising staff awareness about the
- introduction of meters to monitor electricity
- monitoring flora and fauna.

¾ Coquelles Terminal
Water sampling
A 30km network supplies the drinking water and industrial water required for
maintenance activities and fire-fighting throughout the entire infrastructure
(approximately 115 fire hydrants). This network can be backed up by an emergency
supply from a 500m3 reservoir, an 800m3 groundwater reservoir and storage lagoons.
This network is supplied by SMOC (Syndicat Mixte de l’Ouest du Calaisis).

Stormwater discharge
The ‘wateringues’ (from "water" and "rings") system is a local drainage system for
protecting the Calais / Dunkerque / Saint-Omer coastal plain, which is below sea level at
high tide, created in 1169 by Philippe of Alsace and perfected over the centuries.
Eurotunnel took this historical local feature into account in the design of the French
Terminal: wateringues (drainage ditches) and streams were created following an
hydraulic survey. Prefectoral consents were granted to the organisations involved in
these developments (SNCF, DDE, France-Manche). Two of these consents were granted
to Eurotunnel.
Storage lagoon and pumping system
2006 Environment report
In 2006, MISE (Mission Inter-Services de l’Eau du Pas-de-Calais) wanted to check the
discharge points in order to modify the Prefectoral discharge consents for Coquelles and
At the same time, Eurotunnel introduced a preventive maintenance initiative to check the
oil interceptors (35 interceptors located at various points throughout the French site) in
order to avoid any pollution risk that could arise if one of them were to malfunction and
to obtain a better quality discharge water.

Waste water treatment: purification plant
The urban biological purification plant built by Eurotunnel at Coquelles has a nominal
capacity equivalent to a population of 13,500. This plant treats the waste water from the
Eurotunnel Terminal as well as some of the waste water from Coquelles and the nearby
development area (Cité-Europe).

Urban purification plant
This year, wastewater discharge quality at the plant remained in compliance with the
regulations. Performance data is available from the Agence de l’Eau Artois–Picardie
website: www.eau-artois-picardie.fr
As far as operation of the purification plant is concerned, the installation of an automatic
filter for sludge treatment has cut the station’s water consumption by 95% (from
3,401m3 in 2005 to 155m3 in 2006).
Sludge spreading
This station produces residual sludge which has to be properly eliminated. A study was
carried out prior to spreading, focusing successively on six points:
- assessment of the quality and quantity of sludge to be spread
- delimitation of land for spreading
- survey of farms
- soil studies and environmental constraints
- definition of agronomic monitoring
- study of alternative solutions
MISE approved this study and confirmed where and how the spreading was to take place
on three farms on land in Coulogne, Sangatte and Peuplingues representing a total area
of 177 hectares. As an alternative solution to using limed sludge for agricultural
purposes, there are plans to spread liquid sludge on nineteen hectares of temporary
meadows on Eurotunnel’s land.

Down 38% on 2005:
- the 800 cubic metre fire-fighting water
reservoir is now supplied by groundwater
pumped out of the Beussingue cutting at
the Tunnel entrance (22,500m3). A new
system has been introduced to avoid
having to use the town supply system.
- The changes made in 2005 in the
method and frequency of use of the
pumps and tunnel cooling loops have
reduced the quantity of water used in
cooling in 2006 in Britain and France by
30% (3,000m3). This reduction may
fluctuate over time depending on
seasonal weather conditions (climate
change); the Tunnel requires more cooling in very hot periods.
Wastewater and rinse water from cooling circuit filters are discharged into the Sangatte
town purification plant.
In 2006, Eurotunnel signed an agreement for wastewater discharge into this purification
plant with Communauté d’Agglomération du Calaisis and studied possible substitutes to
replace the product currently added in the Tunnel cooling system with one that would be
more environmentally friendly.
2006 Environment report
¾ Folkestone Site
Drainage water
Although not required under UK law, a monthly drainage water quality check was
implementedin 2003 at the final discharge point upstream of the discharge to the sea.
The six parameters measured are: suspended solids, hydrocarbons, COD, BOD, pH and
The results of these checks confirm that the quality of discharges is satisfactory.
Full water
Wastewater is discharged directly into the Folkestone town purification plant.
¾ Shakespeare Cliff Site
The Shakespeare Cliff site is the equivalent of the Sangatte site on the French side
(cooling plant, ventilation plant, shaft, etc.).
Eurotunnel is authorised to discharge to sea the filter rinse water from the cooling
system and drainage water from the site and the tunnel. The results of the monthly
checks are satisfactory.

¾ Carbon footprint
All manner of human activities directly or
indirectly generate greenhouse gas emissions.
It is therefore right that all companies,
authorities and groups take an interest in the
emissions that they generate. In order to act it
is necessary to calculate the carbon footprint.
Carbon footprinting is a method of calculating
emissions based on data obtained from the
The carbon footprint includes direct or induced
emissions: emissions associated with energy,
construction, operations, business travel, etc.
To strengthen its sustainable development initiative, Eurotunnel reviewed its carbon
footprint with the help of a specialist ADEME-accredited firm. In order to pinpoint the
actions that needed to be undertaken, three analysis sub-areas were identified: operations
activities, maintenance activity and business services. The results will be known in 2007
and an emissions reduction plan will be introduced.
The train represents one of the most ecologically sound means of transport and
Eurotunnel is the least polluting cross-Channel operator.
¾ Fire extinguishing system
The fire protection systems originally installed in the Tunnel, associated installations and
rolling stock use Halon. This gas is banned under the Montreal Protocol. Some users are
exempt because the equipment concerned is considered sufficiently critical (Eurotunnel,
Air Forces, etc. / European Regulation n°2037/2000). That exemption is reviewed
annually by the European Commission.
The exemption does not cover new installations which have to use inert gases that are
not harmful to the environment.
Halon storage
The exemption is associated with a number of conditions: total
control of stock, consumption and releases, investigating
alternative solutions and annual declaration to the French
relevant Ministry.
In 2006, studies were carried out to find a replacement. They
identified a substitute product which, when it is installed in the
equipment rooms, will reduce the total quantity installed by 21%
and hence the discharges.
This new extinguishing agent will meet environmental requirements:
- lowest possible ODP (Ozone Depletion Potential)
- lowest possible GWP (Global Warming Potential)
- shortest ALT (Atmosphere LifeTime).
2006 Environment report
¾ Cooling system
Refrigerants are used in the tunnel cooling system, rolling stock air conditioning units
and air conditioning in buildings. The refrigeration experts ensure compliance with the
French Decree 92-1271 of 07/12/92 (amended). Substitute products have already been
tested: R134a in the onboard air-conditioning systems and R409A in the air conditioning
systems in the Krupp locomotives on works trains.
¾ Improving works train exhaust emissions
About 30,000 litres of diesel a month are used to power the works trains. The 17
locomotives are fitted with CO catalytic converters and the 40 works train modules are
equipped with powertrains ranging from 5 to 300KW.
The Krupp locos run on diesel and are coupled with scrubber units which minimise
nitrogen oxide gas emissions.
A further study has been carried out this year with a view to replacing these scrubber
units with more efficient ones that will meet the new European standards for gas
emissions that come into force in 2009-2010.
KRUPP loco and scrubber units
¾ Acceptable noise levels
In Britain, Eurotunnel has installed double glazing in some dwellings in the vicinity of the
site to protect the occupants from any noise nuisance, to comply with the Noise
Insulation Regulations 1975.
In France, the noise levels measured at the property boundaries are below the
regulatory thresholds fixed in the ICPE Prefectoral Order relative to Eurotunnel.
Eurotunnel has stopped broadcasting customer information by loudspeaker at night on
both terminals in order to reduce noise nuisance.
Noise surveys designed to minimise noise pollution are carried out for each new project
or modification to existing facilities. For instance, the diesel power supply unit used for
rail handling is particularly quiet.
2006 Environment report
¾ Electricity consumption
Eurotunnel considers that energy management is a key part of its global business
strategy and is continuing to focus its efforts on reducing its electricity consumption.

Reduction in electricity consumption for auxiliaries:
The remote system for recording electricity consumption has been improved by
increasing the number of meters and developing metering layout software.
Energy consumption by the cooling system in the running tunnels has been optimised.
Further energy savings were made in 2006 by:
¾ optimising heating operation by carrying out the following work:
- modifying the automatic control
- regulating the heating when building entrance doors are open
- switching on the heating when there are personnel in the building
- improving insulation
¾ optimising lighting operation by carrying out the following work:
- installing twilight sensors
- modifying the automatic control
- switching on the lighting when there are personnel in the building
¾ optimising the management of lit areas in the service tunnel.
Reduction in electricity consumption for traction:
The reduction in electricity consumption for traction is primarily related to optimising the
speed of shuttles on non-maintenance nights since 2005.
A feasibility study to reduce aerodynamic resistance in the tunnel and hence the

2006 Environment report
¾ Contribution to the development of renewable energies
The project to install a wind farm at the Coquelles Terminal which was initiated in 2003
resumed in May 2006 in partnership with the company InnoVent. Eurotunnel is looking to
install three 2 MW wind turbines by the end of 2008.
2006 Environment report
¾ Validation of hazardous substances
All hazardous substances are controlled from the time they are purchased until such time
as they are disposed of.
Authorisation to use any new substances is systematically validated by risk assessments
carried out by:
- the Safety Department
- the Maintenance Technical Departments
- the Occupational Health Department
- the Environment Department.
The process culminates in recommendations for using the substances.
¾ Continual improvement of storage areas
Eurotunnel has been exercised great care for
many years now with regard to conditions for
storing its hazardous substances in the UK and in
In 2006, to comply with the Control of Pollution
(Oil Storage) (England) Regulations 2001, an oil
storage area was constructed for the works train
and transport department: leakproof double skin
oil tanks were installed.
¾ Pollution prevention
In 2005, Eurotunnel adopted a new process to prevent any fuel spillages from freight
vehicles from running into the stormwater drainage system: a retention kit (hydrophobic
absorbent pillows and a peat blanket) to be positioned under the defective tank and the
leak to be quickly plugged as appropriate.
Equipped breakdown truck
2006 Environment report
In 2006, another faster, more efficient process
was introduced: a breakdown truck has been
equipped with an explosion-proof pump capable of
taking over 400 litres of fuel a minute; it has two
retention tanks with a total capacity of 980 litres
(equivalent to two lorry tanks).
This process will prevent hundreds of litres of
diesel from leaking onto the ground.
¾ Identifying explosive atmosphere risks (ATEX)
An explosive atmosphere (ATEX) is a mixture with air and flammable substances in the
form of gases, vapours, mists or dusts in which, after ignition has occurred, combustion
spreads to the entire unburned mixture. Protection from explosions is clearly of vital
importance to safety, but also to the environment.
In 2005, Eurotunnel mapped the risks on the French Terminal, classifying its premises
potentially at risk from explosive atmospheres into different areas (called ATEX).
Appropriate prevention and mitigation measures have been defined and implemented,
such as signing of ATEX areas, installations and equipment use.
In 2006, the same process was undertaken on the UK Terminal in accordance with the
Dangerous Substances and Explosive Atmospheres Regulations 2002.
2006 Environment report
Eurotunnel introduced the selective collection of special and
ordinary industrial waste at the two Terminals back in 2002.
Selective collection has necessitated an overhaul of all
equipment and facilities, the modification of waste flows and
the creation and fitting out of waste collection centres.

Advertising campaigns aimed at staff and
sub-contractors focused on the sorting and

posters, etc.)
Example of a poster campaign in late 2006 in
UK staff buildings ->
We need you to help us to
achieve our ultimate aim of
recycling over 50% of our waste.
¾ Waste management on the French Terminal
Improving selective waste sorting
Since September 2006, waste has been outsourced to a new waste collection and
treatment company (Opale Environnement, part of Groupe SECHE). The treatment
processes are now closer. Ordinary waste is transported to a sorting centre close to the
site, while hazardous industrial waste is taken to
a regional collection centre where material or
energy recycling are important priorities.
A new collection system called "Recyclosaure" is
also used, thus eliminating the need for a general
waste compactor (energy saving). Waste is taken
away by a huge household waste truck with on
onboard weighing system which collects waste
from various companies (reduction in transport).
Efficiency of waste sorting
In France, the results have been encouraging since selective collection was introduced.
The final disposal sites (CSDUs) apply their Prefectoral Order, taking a zero-tolerance
approach to the waste that they will accept from Eurotunnel.
Eurotunnel’s waste reject rate has been going down for a number of years now. It has
halved since 2003 and needs to reach the 0 reject target.
2006 Environment report
In 2006, only just a little more effort is needed on 2% of the quantity sent to landfill to
achieve optimum sorting.

requires special treatment: the recycling company
requires a pH between 5 and 7. Every three
months an external laboratory carries out a
bacteriological test for Legionnellosis.

2006 Environment report
dans le
When the construction period was over, Eurotunnel adopted a policy for managing the
green spaces on its land and set up a system to monitor the flora and fauna on the
Terminal, with the aim of:
- gaining a clearer insight into how the ecological balance of the
natural environment evolves
- understanding how both protected and unprotected animal and plant
species evolve in their natural environment.
¾ Monitoring fauna and flora
Groupe Ornithologique du Nord has been responsible for monitoring the site since 1993
and their work has demonstrated the great heritage value of the French site.
The greylag goose is still nesting on the site and the size of the lapwing population is now
of natural heritage interest in the region. The first inventories of invertebrates have
revealed the rare presence of dragonflies. While there is a trend towards more common
species, wetland species are still present.
¾ Maintaining green spaces
The 300 hectares of green areas on the French Terminal are regularly maintained.
The meadowlands are cut late to control the development of vegetation. This practice
retains the vegetation cover and preserves the species diversity of the vegetation,
leaving the natural environment to express itself.
In the wetland areas, Eurotunnel is very aware of the value of a high quality natural
environment and is supporting the reinstatement of wildlife habitats. The lake in the
Jardins Ordonnés offers considerable potential for the site to develop animal and plant
Controlling vegetation development in the wetlands is especially important in order to
maintain the ecological roles of the reed marsh and the open water surface. The cutting
that takes place outside nesting periods preserves the aesthetic elements and enhances
the environment by helping to diversify the fauna and control the vegetation.
¾ Need for pest control
Eurotunnel controls pests that could seriously damage or potentially disrupt our systems.
Pest control also stabilises populations generally over the 700 hectare site.
Controlling animals classed as pests is a property-owner’s right, but supervised by the
authorities. Trapping is done by a designated competent technician specially trained by
the Fédération Départementale des Chasseurs du Pas-de-Calais and approved by the
Prefect. The annual cull figures are transmitted by the special warden to the Préfecture
and Mairie each year. The special warden also compiles a report, receives complaints,
carries out inspections and makes recommendations for improvement.
In 2006, an increase in the bird population was noted (pigeons, crows, etc.), especially
around the overbridges, platforms, etc.

¾ An ongoing process of development
The decision in 1992 to have the French site officially classed as a ZAC was a deliberate
choice to ensure that the infrastructures directly or indirectly connected with the Channel
Tunnel were beyond reproach in terms of technical quality and their integration into the
environment around Boulogne and Calais. In-depth environmental impact studies
detailing the hydro-geological environment, vegetation and wildlife were carried out.
Sustainable development concerns were taken into account: the Habitat 62/59 offices are
an environmentally-sound building; the ACCOR hotels have solar heating.
Following demolition of the concrete floor of the former plant, building which was
requisitioned by the French Government for the Red Cross Centre between September
1999 and December 2001, a concrete crushing plant for the production of road
aggregates has been built. The site has been reinstated.
As far as new development projects are concerned (Sangatte leisure area), Eurotunnel is
supporting the Mayor of Sangatte/Blériot Plage in a scheme to develop the area. The
project covers an area of 110 hectares, 35 of which are owned by Eurotunnel, and
includes a golf complex and an environmentally sensitive housing development.
The proposed footprint of the golf course does not
encroach on the natural environment and is
surrounded by areas of regenerated land designed so
that the course blends in with the landscape and its
environment. The course has been designed in
accordance with AGREF guidance (Association
française des personnels d’entretien de terrains de
golf) and the ‘Commitment to green’ standard to
ensure that environmental principles are respected.
The housing development is a direct continuation of the existing urbanised and industrial
areas and is located on the site of the old segment casting plant.
A public concession procedure for the development is going to be launched by the
Sangatte/Blériot Plage Commune during the second half of 2007. Groupe Eurotunnel will
put itself forward for selection as the concessionaire. If successful, a 12-month project
impact study will be undertaken prior to finalising the DUP application in 2008.
2006 Environment report
The process of revising the master plan, which started in April 2006, involves preparing a
Territorial Coherence Plan (SCOT) for which Groupe Eurotunnel will provide basic
information on its project under the notification procedure initiated by the Direction
Départementale de l’Equipement.

¾ The Folkestone Downs
The Folkestone Downs, covering an area of some 48 hectares, are one of the largest
remaining areas of ancient chalk grassland in Kent and form part of the Kent Downs Area
of Outstanding Natural Beauty (AONB). They are also designated a Site of Special
Scientific Interest (SSSI) on account of the many rare species of plants and wildlife they
When Eurotunnel acquired the land it had not been
managed for some 30 years. Areas were becoming
invaded by scrub, and coarse tor grass (Brachypodium
pinnatum) was rampant, choking out the more delicate
species of flora. Fencing had become dilapidated and
flytipping and abandoned vehicles were becoming
commonplace. There were a number of public footpaths
that had become overgrown or unusable.
The 'on the ground' management is undertaken by the White Cliffs Countryside Project
(WCCP), which enlists the help of volunteers to keep the area in good order. WCCP also
organises guided walks, wildlife conservation activities and Green Gang events for
children. A number of new footpaths have been established to create circular walks and
the public is provided with information in the form of bilingual leaflets and site
interpretation panels to encourage the local community and visitors to Kent to become
Eurotunnel and WCCP have restored and maximised the diversity of habitats on the site
without detracting from its unique components. This was achieved mainly by the
introduction of grazing cattle that control the coarse grasses, allowing the more delicate
species to thrive.
Ongoing ecological monitoring confirms a constantly improving trend in the biodiversity
of the area.
These initiatives have led to an increase in the number of species of
plants on the chalk downs, and particularly wild orchids such as Ophrys
apifera (Bee Orchid), Dactylorhiza maculata (Spotted Orchid), Ophrys
fuciflora (Late Spider Orchid), and butterflies like
Lysandra bellargus (Adonis Blue) and Hesperia
comma (Silver-spotted skipper).
Thirty-one different species of butterfly can now be
seen on the Downs during the year, more than half the number of
species in the UK, making the Kent Downs one of the best places in
the country to observe meadow butterflies.
Against this backdrop of biodiversity, a giant white horse has
been carved out of the chalk downs behind Folkestone. This
artistic creation, visible from a great distance, does not disturb
the delicate ecological balance of the site because it is far
enough away from the place where the orchids grow.

¾ Samphire Hoe
Samphire Hoe is a 30-hectare piece of land situated at the foot of the White Cliffs of
Dover. It was created from approximately 5 million m3 of chalk marl excavated during the
construction of the Channel Tunnel.
The challenge for Samphire Hoe was to transform this conspicuous legacy of the Tunnel’s
construction into a place of environmental interest and make it available to the public for
leisure activities such as walking, birdwatching and sea angling.
The day-to-day
management of the site is
the responsibility of
WCCP, assisted by many
local volunteers.
A flood warning system
has been introduced.
Bilingual interpretation panels explaining the history, wildlife and plantlife of the site were
also used, as well as leaflets. Special attention was paid to disabled access (ramps, good
quality surfaces to footpaths, etc.).
Over 120,000 visitors come to Samphire Hoe each year.
Guided walks and other events are organised and
refreshments and toilets are available. An artistic wooden
structure called Samphire Tower was opened to the public
here in 2004.
The site supports a rich biodiversity, including:
- about 200 plant species, the result of national colonisation of the 31 original
- 12,400 orchids, a rare species in the UK, compared with only 67 in 1998
- 190 bird species, two of which are listed in the Red Data Book
- 27 butterfly species
- about 175 species of moth, including 5 featured in the Biodiversity Action Plan
- 13 species of dragonflies and damselflies.
The mating season was very successful for birds at Samphire Hoe in 2006. The following
have been identified:
21 pairs of meadow pipits (Anthus pratensis)
4 pairs of stonechats (Saxicola torquata)
1 pair of black redstarts (Phoenicurus ochruros)
1 pair of grey partridges (Perdrix perdrix).
are all birds that very rarely breed in Kent.

¾ Environmental achievements
Eurotunnel and the White Cliffs Countryside Project (WCCP) work in partnership to
manage and develop Samphire Hoe and the Folkestone escarpment. This joint venture
has been recognised by a number of awards:
- Property Awards (Environment category) sponsored by Property Week
- Environmental Awards for Kent Business (Site Management and Nature Conservation
category) sponsored by Kent Country Council
- National RICS Award for Countryside & Coastal Regeneration sponsored by the Royal
Institute of Chartered Surveyors
- Site of Special Scientific Interest Award sponsored by English Nature.
In 2005, Samphire Hoe was recognised by the Kent Volunteer Awards (Environment
In 2006, Samphire Hoe was awarded the Green Flag for the second year running in
recognition of its high ecological quality. The Green Flag is awarded by an organisation
called the Civic Trust for a Green Flag Award which sets the national standard for parks
and green spaces in England and Wales.
This standard requires a site-specific management plan and for the site to be freely
accessible to the public.
There are eight key criteria:
a welcoming place
healthy and secure
clean and well maintained
conservation and heritage
community involvement
2006 Environment report
Eurotunnel has accorded the same paramount importance to Sustainable Development as
it has to Safety. It is looking forward to seeing several beacon projects that it has been
preparing for several years come to fruition in 2007:
- signature of its framework agreement with and the Nord/Pas-De-Calais Region for a
partnership-based approach aimed at raising awareness among its customers, subcontractors and suppliers on the major issues of global warming and protecting the
- installation of three wind turbines on its Coquelles site, further confirming the
company’s commitment to energy management
- signature of an agreement with the Conservatoire de Sites Naturels and the Groupe
Ornithologique du Nord with a view to introducing a multiyear species and spaces
management plan for its Coquelles Terminal and raising this site to the same ecological
standard as the Samphire Hoe site which is well known in Kent by ramblers and nature
lovers and a regular award-winner.
