Sustainability at AIXTRON

Our csr responsibility as a company

Acting responsibly and prudently

We know that social, environmental and economic activities and performance 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 shaped by sustainability. This is reflected in our CSR policy which sets out guidelines for responsible and sustainable business activity.

Sustainability is much more than mere compliance with ordinances and regulations. It must be the expression of a constant and serious effort to permanently improve our economic, ecological and social aspects. We also want our employees to be motivated to work for a responsible company and develop products and technologies that can help change the world.

AIXTRON's deposition equipment - a global leader in the semiconductor industry - is used to manufacture high-performance devices for electronic and opto-electronic applications based on compound and organic semiconductor materials.

We can exert a particular influence through the design and development of our products. Through our forward-looking technologies, but also through the use of Industry 4.0 processes, we contribute to a significant reduction in the energy consumption of our customers' products and their customers. For example, power devices (III-V semiconductors) made of gallium nitride (GaN) with large bandgap, such as those manufactured on our equipment, require significantly less energy for the same or higher performance compared to conventional silicon-based power chips.

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


AIXTRON is committed to climate protection


Climate protection plays an important role for AIXTRON. We attach great importance to keeping the ecological footprint left by our business activities as small as possible and to minimizing the release of climate-damaging CO2 emissions.

AIXTRON stands for energy-efficient technologies worldwide: with our products and solutions, we contribute to greater energy efficiency in numerous key industries and thus take an active role in reducing avoidable greenhouse gas emissions. We have had an ISO 50001-certified energy management system in place since 2014, which forms the basis for implementing effective energy efficiency measures at AIXTRON.

From now on, we are taking climate protection one step further: In order to avoid impacting our climate as much as possible, AIXTRON has been sourcing its electricity entirely from renewable sources since 2019, thus making an important contribution to avoiding greenhouse gas emissions. As part of our company-wide climate efficiency strategy, we compensate for the remaining CO2 emissions caused by business travel, building heating, and commuting (Scope 1 and 2, as well as a portion of Scope 3 emissions), for example, through certified climate protection projects. AIXTRON thus achieves the status of a climate-neutral company.

The principle of CO2 compensation

The compensation of CO2 emissions is based on the principle of global climate balance: For the climate, it is irrelevant where in the world emissions are generated and where they are saved. Therefore, it is possible to offset unavoidable emissions that occur in one place on earth by additional climate protection measures in another place.

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.

Support for climate protection projects in South America and Africa

We support two certified climate protection projects in Peru and Uganda to offset the CO2 emissions. The project in Peru is a forest protection project in the Amazon region "Madre de Dios", the project in Uganda is an energy efficiency project to improve the living situation and environmental conditions.


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 security

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

"Trust and safety" was particularly important to us during project selection. We therefore ensured that both projects are certified in accordance with the "Verified Carbon Standard" and the "Gold Standard" respectively, and thus meet demanding and internationally recognised standards. The emission savings achieved are regularly verified and confirmed by independent experts. In addition to the avoided CO2 emissions, the projects bring further very tangible benefits for the local people and environment, for example by creating jobs and contributing to the protection of valuable ecosystems.
