Aixtron

AIXTRON, a German semiconductor machinery manufacturer, is committed to reducing its carbon emissions and has set ambitious climate targets.

In 2025, AIXTRON's total carbon emissions are projected to be about 461.9 million kg CO2e. This includes approximately 127,000 kg CO2e from Scope 1 emissions, 270,000 kg CO2e from market-based Scope 2 emissions, and about 461.5 million kg CO2e from Scope 3 emissions. A significant portion of its Scope 3 emissions in 2025 comes from the use of sold products, accounting for approximately 422.9 million kg CO2e.

Looking back, AIXTRON's reported total emissions were about 493.7 million kg CO2e in 2024 and approximately 426.3 million kg CO2e in 2023. In 2022, total emissions were around 380.3 million kg CO2e. The company reported a significant decrease in total emissions between 2019 and 2020, with a reduction of almost 52%, from approximately 4.2 million kg CO2e in 2019 to about 2.0 million kg CO2e in 2020 for Scope 1 and Scope 2 combined.

AIXTRON has set both near-term and long-term Science Based Targets initiative (SBTi) validated targets. For its near-term goals, AIXTRON commits to reducing absolute Scope 1 and 2 GHG emissions by 60.0% by 2034 from a 2023 base year. Additionally, it aims to reduce absolute Scope 3 GHG emissions by 40.0% within the same timeframe. These near-term targets are classified as consistent with a 1.5°C warming pathway.

For its long-term ambitions, AIXTRON is committed to achieving net-zero greenhouse gas emissions across its entire value chain by 2045. This includes a commitment to reduce absolute Scope 1 and 2 GHG emissions by 95.0% by 2045 from a 2023 base year, and to reduce absolute Scope 3 GHG emissions by 95.0% within the same long-term period. These long-term targets are also classified as consistent with a 1.5°C warming pathway. The company has submitted a Letter of Commitment to the Science Based Targets initiative (SBTi).

AIXTRON's transition plan to achieve its climate targets aligns with the Paris Agreement and focuses primarily on reducing Scope 3 emissions, particularly from the use of sold products through efficiency improvements. It also includes measures to further optimise Scope 1 and Scope 2 emissions, such as the use of Guarantees of Origin for renewable electricity and the implementation of waste heat recovery systems. The company also highlights its Clean Energy Project, aiming to largely replace CO2-intensive energy sources like district heating and natural gas at its production sites.
