United Internet's Carbon Emissions & Climate Commitments

In 2025, United Internet, a leading German Post and telecommunication services provider, reported total carbon emissions of approximately 992.5 million kg CO2e. This includes about 4.2 million kg CO2e from Scope 1 emissions, 2.8 million kg CO2e from Scope 2 market-based emissions (or 65.5 million kg CO2e location-based), and roughly 985.5 million kg CO2e from Scope 3 emissions. A significant portion of Scope 3 emissions stemmed from purchased goods and services, accounting for about 702.1 million kg CO2e.

Looking back, United Internet's total emissions were approximately 1.14 billion kg CO2e in 2024 and 1.13 billion kg CO2e in 2023.

United Internet has robust climate commitments, aiming for net-zero emissions by 2045, aligned with the Paris Agreement and the European Climate Act. This long-term goal is supported by interim Science Based Targets initiative (SBTi) aligned targets. Specifically, they plan to reduce their Scope 1 and Scope 2 emissions by 55% (approximately 5,141 tonnes CO2e) by the end of 2030, relative to a 2023 base year. The overall long-term target is to achieve a 90% reduction in Scope 1 and 2 emissions by 2045 compared to 2023 levels.

Additionally, United Internet's 1&1 IONOS Holding division has committed to climate-neutral data centre operations since 2019 for both Scope 1 and Scope 2 emissions, achieved by sourcing renewable energy and offsetting non-renewable electricity use. IONOS is also a certified VMware Zero Carbon Committed Partner, pledging to power its data centres with renewable energy by 2030. United Internet aims to reduce its Scope 1 and 2 emissions to near zero by the middle of this decade.
