ENERGY MANAGEMENT SYSTEM
The AMTC operates an energy management system in accordance with ISO 50001 to ensure sustainable operations right from the planning and procurement stages of machinery and equipment, through to their operation and maintenance. Opportunities for energy savings are continuously identified and implemented. We thrive to make a contribution to climate protection.
Therefore AMTC has set itself strategic targets, such as reducing the energy consumption required to produce a photomask by 50 % by 2025, compared with 2013. By 2025, we had achieved a reduction of more than 60 % in energy consumption compared with 2013. That means, today producing a photomask requires just under half the energy consumed by a three-person household in a year.
The technical equipment is continuously monitored to ensure optimal operation and to prevent malfunctions. This also enables us to save additional costs. For example, in 2025 we replaced our heat vessels, formerly operated with natural gas, with a large heat pump. This measure enabled us to make significant savings on natural gas in 2025, thereby improving our carbon footprint - by 2026, we have nearly eliminated our natural gas consumption.
CARBON FOOTPRINT
Reducing CO₂ emissions is one of the strategic objectives of our energy and environmental management. The best way for us to improve our carbon footprint in the long term is to purchase electricity from renewable energy sources. Total CO₂ emissions from the consumption of electricity and natural gas (which form part of Scope 1 and 2 GHG emissions) have thus been reduced by over 10,000 tons of CO₂ per year since 2013 – despite a triple increase in production volume!
In addition to emissions from energy consumption, we track other sources of emissions that are covered in Scope 1 and 2. AMTC’s current emissions balance is as follows:
In 2025, Scope 1 and 2 CO₂ equivalent emissions at the site totalled 463 tons.
To support European climate protection efforts, the AMTC has set itself the target of reducing Scope 1 and 2 CO₂ emissions to net zero by 2035. The key measures are the installation of a heat pump powered by renewable electricity in 2025 and in 2026 the replacement of three of the four abatements with technology powered by renewable electricity. Through these measures – primarily the phasing out of processes reliant on fossil fuels – we can succeed in moving our Scope 1 and 2 emissions towards net zero.
Furthermore, the AMTC regularly engages with various sustainability platforms and networks to continuously improve climate-related measures and to participate in the exchange of best practice.
Scope 3 emissions currently arise mainly from the procurement of materials and services, as well as new equipment. Because we are expanding, we are working together with our suppliers on sustainable products and services.
ENVIROMENTAL PROTECTION
To preserve our natural resources and reduce our operational impact on the environment, we have maintained a certified environmental management system in accordance with DIN EN ISO 14001 since 2006. Our focus is on continuous improvement, compliance with all legal requirements, and our employees themselves, who can help shape processes through their suggestions for improvement.
One example of our active work on environmental protection issues is our strategic water goal. The production of ultrapure water is not only energy-intensive but also generates wastewater due to the high purity requirements. We have once again set ourselves an ambitious goal and aim to reduce our water consumption by 15% by 2030, taking into account our production expansion.
By adjusting rinsing processes and reusing uncontaminated wastewater, we have already been able to gradually reduce our consumption by the end of 2024, which corresponds to an annual savings of more than 260,000 filled bathtubs. We are pleased to achieve such goals—for a healthy environment, including for future generations.
COMMITMENT
As a sign of our commitment to a climate-neutral future, we are actively involved in the Climate Neutrality Network as part of the Energy Efficiency and Climate Protection Networks initiative.
