AIRBUS AN ECO-EFFICIENT ENTERPRISE
Airbus is set to contribute to sustainable growth - a growth compatible with the environment, and to
continue delivering solutions to a world that wants greater mobility… and a cleaner and quieter
future.
Airbus is totally committed to ensuring that air travel continues to be one of the safest, and most
eco-efficient means of transportation. Environmental, health and safety (EHS) considerations have
long been an integral part of its activities at all levels of the company, and are a key priority in the
development of all new techniques, products and processes. Today, it makes even stronger
business sense.
Despite the fact that the aviation’s contribution to overall CO2 man-made emissions is expected to
remain low compared to other sectors within the coming decade (ca. two per cent of man-made
CO2 emissions), no other sector makes such important relative investments and efforts to decouple
its growth from the associated environmental impacts.
As an aircraft manufacturer, Airbus is committed to ensuring that growth of our industry is Eco-
Efficient.
Eco-Efficiency is not about greenery.
Eco-Efficiency is a management practice, allowing being more environmentally responsible while
bringing more profitability and social benefits.
In brief, it is about creating more value with less environmental impact, enlarging the scope to the
full lifecycle and anticipating issues at the earliest possible stage. Eco-Efficiency aims at
maximizing the benefits delivered by our products and services to our customers and other
stakeholders while minimizing the Environmental impact throughout their lifecycle.
Becoming more Eco-Efficient makes good business sense. Building aircraft Eco-Efficiently on the
ground that will operate Eco-Efficiently in the air is the Company’s core business.
In January 2007, Airbus became the first company in the aerospace manufacturing sector to
receive the ISO 14001 environmental certification covering all its 15 European manufacturing
sites and all its product related activities throughout a full lifecycle approach.
This means that Airbus systematically uses a robust Environmental Management System
(EMS) to continually monitor and minimize the environmental impacts of Airbus processes and
products at each stage of the activity throughout the lifecycle.
Design
In the frame of its innovative EMS, based on recognised standards, Airbus has performed a
streamlined lifecycle analysis and set-up a methodology for mapping aircraft environmental
impacts throughout the entire product lifecycle. Performed on a long-range programme in a pilot
phase, this approach has enabled Airbus to identify the environmental issues that matter and to
address them appropriately.
Minimising environmental impacts at source is paramount as design exerts a major influence oncontinue delivering solutions to a world that wants greater mobility… and a cleaner and quieter
future.

each dimension of aircraft’s environmental performance. Environment is therefore part of toplevel
requirements for the design of any new product. That’s why 80 per cent of the company’s
€2 billion Research & Development (R&D) has environmental benefits for current and future
aircraft. Airbus’ Research & Technology (R&T) efforts are focused on investigating, testing,
validating and optimising the most advanced technologies, design features, configurations and
architectures that will lead to aircraft generating fewer emissions and less noise, while carrying
a maximum payload over the mission range.
Reducing engine emissions is a priority for Airbus. In addition to optimised propulsion systems
and overall aerodynamic efficiency, a major area of research is the continuous and progressive
introduction of advanced materials and new processes to reduce the basic weight of an aircraft
to minimise fuel consumption and corresponding engine emissions. The A380 is the first
commercial aircraft to incorporate as much as 25% composites. With a carbon-fibre-reinforced
plastic composite centre wing box, a weight saving of up to 1.5 tonnes has been achieved. With
less than three litres per passenger per 100 kilometres the A380 has a very low fuel burn. This
corresponds to less than 75 grammes of CO2 emissions per passenger per km.
Reducing noise at source is a similar priority. The company is not only working on low-noise
nacelle designs, acoustic treatments, and low engine noise technologies hand-in-hand with
engine manufacturers. One such innovative project is the 0-splice inlet technology for engine
nacelles to reduce fan noise. It also contributes to the remarkable noise performance of the
A380 that shows unprecedented certified noise levels with a 17-EPNdB cumulative margin to
the most stringent ICAO Chapter 4 standard, and satisfies the noise requirements of the most
restrictive international airports.
Airbus has also taken on board an ambitious Research and Technology Vision and signed on
13th October 2006 the Memorandum of Understanding to establish the Aeronautics Joint
Technology Initiative (JTI) “Clean Sky”. This JTI is a large seven-year industry-driven
technological research programme that will radically improve the impact of air transport on the
environment through technologies and solutions enabling step changes in the reduction of fuel
consumption, emissions and noise for future aircraft.
Supply chain
Aircraft are one of the most complex products, integrating hundreds of thousands of
components. Therefore, collaborating with the entire supply chain is key to ensuring reliability at
each subcomponent level, and delivering products on time and within budget that satisfy the
highest environmental and quality standards. Environmental requirements are included in the
selection of Airbus Suppliers and are introduced in contractual agreements. Airbus Suppliers
are expected to provide reliable environmental data on the products delivered and to develop
and implement an Environmental Management System.
Tracking and managing hazardous materials has also been for long time crucial to Airbus.
A proactive approach developed in close collaboration with main EU and US aerospace
companies should enable Airbus to best manage its compliance with environmental laws and
