Sustainability at AIXTRON

Our csr responsibility as a company

Act responsibly and prudently

We know that social, ecological and economic activities and services influence each other and have tangible interactions. As a supplier to a pioneering key industry, we conduct our business prudently, responsibly and with the interests of all stakeholders in mind. Our efforts are therefore aimed at a future for our company, our customers and society that is characterised by sustainability.

Sustainability is much more than simply fulfilling regulations and rules. It must be an expression of a constant and serious effort to improve our economic, ecological and social aspects on a lasting basis. We also want our employees to be motivated to work for a responsible company and to develop products that can help change the world.

The deposition equipment of AIXTRON - one of the world's leading suppliers to the semiconductor industry - is used to manufacture high-performance components for electronic and opto-electronic applications based on compound and organic semiconductor materials.

We can influence the design and development of our products to a particular extent. We contribute to a significant reduction in the energy consumption of our clients’ products and their customers by means of our forward-looking technologies, but also by applying industry 4.0 processes. For example, power components (III-V semiconductors) made of gallium nitride (GaN) with a large band spacing, such as those manufactured on our systems, require considerably less energy for the same or higher performance than conventional silicon-based power chips.

We are also continuously reducing the environmental impact in the manufacturing process and in our building technology by using energy and other natural resources consciously and responsibly.

AIXTRON commits to climate protection


Climate protection is important for AIXTRON. We attach great priority to making sure that the environmental footprint of our business activities is as small as possible and to minimizing the release of emissions of CO2 harmful to the climate.

AIXTRON is known worldwide for its energy-efficient technologies: Our products and solutions help to enhance energy efficiency in numerous key industries and thus play an active role in cutting avoidable greenhouse gas emissions. We have had an energy management system certified under ISO 50001 since 2014 already. This forms the basis for implementing effective energy efficiency measures at AIXTRON.

In our efforts to protect the climate, we will be going one step further from now on. To minimize the burden on our climate as far as possible, since 2019 AIXTRON has procured all of its electricity from renewable energies and is thus making a major contribution to avoiding greenhouse gas emissions. Within our companywide climate efficiency strategy, we will with immediate effect be offsetting remaining CO2 emissions, such as those caused by business travel, heating buildings, or journeys to and from work, by means of certified climate protection projects. This way, AIXTRON has become a climate-neutral company.

The principle of CO2 compensation

Compensation of CO2 emissions is based on the global climate balance principle: Where in the world the emissions arise and where they are saved makes little difference to the climate. That makes it possible to offset unavoidable emissions arising at one place in the world with additional climate protection measures somewhere else.

Within the Kyoto Protocol, the “clean development mechanism” created under the United Nations Framework Convention on Climate Change in 2007 provided a standardized process for CO2 compensation that is now universally recognized. By supplementing measures to reduce avoidable greenhouse gas emissions, compensation can make an important contribution to achieving the targets set in the Paris Agreement on climate protection.

Forest protection project in madre de dios (Peru)

In close cooperation with local residents, measures and initiatives are being implemented to use the forest on a sustainable basis and access alternative sources of income for the population. This way, the area is being protected aganins deforestation. As well as contributing to climate protection, the project is also helping to protect the lovelihoods of two indigenous communities in the region and to preserve the forest as a valuable ecosystem for flora and fauna.

Energy efficiency project in Kampala (UGANDA)

In the project in Uganda, we are supporting the distribution of energy-efficient cookers for households in the metropolitan region of Kampala, the country’s capital city. The enhanced cookers help families to save up to 50% of the fuel. Not only that, they reduce the concentration of harmful substances in the air in kitchens and living rooms. To date, more than 525,000 enhanced cookers have been produced and passed on within the project. Thanks to the lower volume of charcoal used, the project is making a sustainable contribution towards easing the strain on the climate.

Trust and safety

By using CO2-neutral green electricity, we are reducing our carbon footprint and by supporting these two projects, we are offsetting exactly the amount of CO2 that corresponds to the remaining emissions from our other business activities.

"Trust and safety" was particularly important to us when selecting the projects. We have therefore made sure that both projects are certified according to the "Verified Carbon Standard" and the "Gold Standard" and thus comply with ambitious internationally recognized standards. The emission savings achieved are regularly reviewed and confirmed by independent experts. In addition to the avoided CO2 emissions, the projects bring further concrete benefits for people and the local environment, for example by creating jobs and contributing to the protection of valuable ecosystems.
