We believe in building a high performance business and are committed to delivering safe, high quality products and services

Our high standards of business ethics and governance have helped us to become a market-leading global engineering business delivering high quality products and services that touch people’s lives around the world.

We also believe in creating a culture of continuous improvement across GKN Aerospace, applying the Lean Enterprise model to everything that we do. While we want to win in business, we must do so fairly, and the GKN Aerospace Code requires honest and proper conduct from all GKN Aerospace employees. We also expect the same from our suppliers and other business partners.

Sustainable products

GKN Aerospace continues to invest a significant proportion of its R&D spend each year on enhancing fuel efficiency and reducing emissions within aircraft.


Wing of tomorrow

Airbus A350 1000 On Flying Display At Paris Airshow 2017

GKN Aerospace is a key partner in the Wing of Tomorrow composite spar project. The UK Aerospace Technology Institute funded programme led by Airbus UK aims to provide technologies for a sustainable Future Single Aisle Wing.

A composite wing is the most significant opportunity 
for the Single Aisle airframe to improve aerodynamic performance, reducing global CO2 emissions by many millions of tonnes every year.

The work is being undertaken in GKN Aerospace’s new Global Technology Centre in Bristol, UK, with the business investing more than £25 million in the programme over three years.


Reduction of aircraft fuel consumption

Our world-leading additive manufacturing capability has led to the introduction of lighter and more efficient Fan Case Mount Ring (FCMR), leading to a reduction of 20% in emissions and has accelerated the inaugural flight testing of lightweight, recycled thermoplastic components with Bell on the V-280 Valor helicopter. Read more.

Our fan blade housing structure allows significant reduction in source material use, energy consumption and product weight, with a view to reducing greenhouse gas emissions in both the manufacturing process and across the product life cycle.

Technological advancements were made in 2020 using unique Laser Metal Deposition (LMD-w) fabrication techniques, enabling us to secure our position as supplier of choice to Pratt & Whitney for the PW1500G engine, which will be used on the Airbus A220. The project is currently in its production start-up phase with first serial production expected in 2021.

GKN Aerospace’s new fabricated FMCR promotes resource efficiency by reducing the buy-to-fly ratio from 15 in the original design to five. This represents a 60% reduction in material waste, which will save over 90 tonnes of forged titanium annually.

Additionally, the FCMR reduces fuel burn by 20%, which translates to an estimated saving exceeding three million tonnes of CO2 on products manufactured to date.

This project illustrates how we are using our unique fabrication capabilities to reduce costs to our customers and provide broader societal benefits by accelerating the reduction of aircraft fuel consumption.



We are also leading the development of a ground-breaking liquid hydrogen propulsion system for aircraft. The c.£55 million collaborative H2GEAR programme will push hydrogen technology and accelerate aerospace decarbonisation with the goal of zero CO2 emissions hydrogen-powered sub-regional aircraft entering the skies as early as 2026.

The H2GEAR programme will create more than 3,100 jobs across the UK and reinforces the UK’s position at the forefront of aerospace technology research and development, as well as putting GKN Aerospace at the heart of the technology developments needed for the future of more sustainable aviation.

First electric commuter aircraft

Eviation and GKN Aerospace continue their quest to deliver the world’s first electric commuter aircraft (Alice).

In development since 2015, Alice will be capable of operating in the lower end of the regional market carrying nine passengers and two crew members on journeys up to 800km. Regional and domestic air travel account for a large part of aviation’s CO2 emissions, with CO2 produced per km per passenger for flights of less than 500km almost double that of flights over 1,000km.

Battery-powered aircraft are a key part of the journey towards zero-emission aviation. We are providing our expertise across the integration of large-scale components including the complete wing, the complete tail including empennage, and electrical wiring interconnection systems.

Design and manufacturing activities are already ongoing on-site at Eviation in Israel and in several of our engineering centres across Europe, and we are targeting an Entry into Service date of 2022.

Clean Aviation in Europe

In 2019, we signed the Joint Declaration of European Aviation Stakeholders related to Clean Aviation in Horizon Europe, committing to a European Partnership towards achieving goals of the Paris Agreement.

GKN Aerospace has committed to achieving net zero GHG emissions by 2050 and designing products that enable its customers to develop aircrafts that emit net zero GHG emissions throughout their life cycle by 2050.

To meet these longer term goals, we have set an interim target of reducing our Scope 1 and Scope 2 GHG emissions by 5% annually.


Sustainable Aviation Fuels

GKN Aerospace Sweden is leading in the testing of Sustainable Aviation Fuels. Ground-breaking development in the use of biofuels in aviation could lead to huge reductions in carbon emissions.

Test flights using the Gripen RM12 engine powered 100% by biofuel have so far shown excellent performance both in flight and on the ground.

The biofuel used is fully interchangeable with normal jet fuel and no engine changes or modifications are required.

Product Life Cycle Management

Additive Termisk Centre

We assess the impact of our products on the environment in terms of material usage, waste, energy usage and CO2 emissions throughout each product life cycle.

By incorporating circular economy principles in our design and manufacturing processes, we are reducing our environmental impact and deliver products to end markets with increased durability and longevity and reduced waste.

By way of example, our technologies ensure that only 20% of procured metal billets are removed in the production process, whereas the norm is up to 80%, therefore significantly reducing the ‘buy to fly’ ratio.


Responsible Sourcing

We are committed to ensuring that we source raw materials and manufacture products in a responsible, ethical, and sustainable manner. This applies to our global supply chains and is important in mitigating the risk of supply chain shocks.

We closely with suppliers to ensure they respect human rights and promote good working conditions across their supply bases. In practice, this means that suppliers are expected to treat their workers equally and with respect and dignity, for all workers to be of an appropriate age in compliance with the local legal minimum age for work, for all workers to be paid a fair wage that meets or exceeds the legal minimum standard or prevailing industry standard, to eliminate excessive working hours for all workers in compliance with local laws, and for all workers’ health and safety rights to be protected at work.

GKN Aerospace makes available a supplier code of conduct that applies globally to all our suppliers and is based on the ethos of ‘doing the right thing’.
