Adtran

In 2025, Adtran reported a total of approximately 764.6 million kg CO2e in greenhouse gas emissions. This figure encompasses Scope 1, Scope 2 (market-based), and Scope 3 emissions. Scope 3 emissions constituted the largest portion, accounting for approximately 754.4 million kg CO2e. The use of sold products was the most significant contributor within Scope 3, at about 679.5 million kg CO2e, followed by purchased goods and services at approximately 33.8 million kg CO2e. Scope 1 emissions were around 552,000 kg CO2e, and Scope 2 emissions, calculated on a market-based approach, were approximately 5.66 million kg CO2e.

Adtran has set ambitious climate commitments, including a long-term goal to achieve net-zero greenhouse gas emissions across its value chain by 2048. To support this, the company has established several reduction targets:

• A commitment to reduce absolute Scope 1 and Scope 2 greenhouse gas emissions by 90% by 2034 from a 2016 base year.
• A commitment to reduce absolute Scope 3 greenhouse gas emissions from purchased goods and services by 95% by 2048 from a 2016 base year.
• A commitment to reduce absolute Scope 3 greenhouse gas emissions from the use of sold products by 95% by 2048 from a 2016 base year.
• Near-term targets include the reduction of absolute Scope 1 and 2 GHG emissions by 74.5% by 2032 from a 2016 base year, and a 40% reduction in absolute Scope 3 GHG emissions within the same timeframe.
• Additionally, Adtran aims to reduce its Scope 1 and Scope 2 emissions to near zero by 2025.

These commitments are aligned with a 1.5°C trajectory, indicating an effort to limit global warming.
