Sustainability

Sustainability is a key part of the BVG – today and in the future.

Climate Protection & Climate Adaptation

An attractive public transport system is a vital component of the transition towards more sustainable mobility. We aim to encourage more people to use buses and trains while reducing our own greenhouse gas emissions in the long term. To achieve this, we are electrifying our operations, gradually converting our bus fleet to alternative drive systems, and strengthening the resilience of our infrastructure to the impacts of climate change.

  • 634,568 t CO₂e of greenhouse gas emissions across the entire value chain in 2025.
  • Around 80 % of emissions are generated along the value chain. This is why suppliers and procurement processes will play a greater role in our efforts in the future.
  • Around 280 electric buses were in operation in 2025. Compared with operating comparable diesel buses, this resulted in a calculated reduction of approximately 13,651 t CO₂e.
  • Expansion of charging infrastructure and the gradual conversion of the bus fleet to low-emission drive systems.
  • Climate risk analysis and measures to adapt to increasing heat, heavy rainfall, and other extreme weather events.

Energy

We continuously work to use energy efficiently and increase the share of renewable energy. Energy efficiency is an important lever for conserving resources, reducing operating costs, and contributing to climate protection.

  • Since 2014, our electricity consumption for transport operations and at our properties has, on a balance-sheet basis, been covered by electricity from renewable sources, as demonstrated by Guarantees of Origin (GoOs).
  • Continuous modernisation and energy-efficient refurbishment of operational buildings.
  • Gradual electrification of heating systems.
  • Assessment and expansion of our own photovoltaic systems and other renewable energy sources.
  • Energy efficiency measures in workshops, depots, and technical facilities.

Air Quality & Biodiversity

We take responsibility for creating a liveable city for tomorrow. When planning, constructing, and operating our infrastructure, we seek to improve air quality and contribute to the protection of nature and biodiversity.

  • Already 66 km of green track infrastructure supports biodiversity and, depending on the location, can retain rainwater, contribute to cooling and reduce noise by up to 3 dB.
  • To contribute to improved air quality in Berlin, we have reduced our nitrogen oxide and particulate matter emissions by 97% since 2015.
  • In 2025, 7 out of 9 major new-build projects (80 %) had documented ecological construction supervision.
  • Use of biodiversity-supporting standards and environmentally considerate lighting concepts.

Our Workforce

Our employees are at the heart of BVG. That is why we are committed to a safe, healthy, and respectful working environment and promote equal opportunities, diversity, participation, and personal and professional development.

  • In 2025, we welcomed 1,561 new colleagues to BVG.
  • berufundfamilie audit: successfully recertified in 2025.
  • Current share of women: 21.4 %.
  • Comprehensive occupational health and safety, prevention, and workplace health management programmes.
  • A wide range of training and professional development opportunities, as well as programmes to attract and retain skilled employees.

Workers in the Value Chain

We are committed to respecting human rights and complying with environmental due diligence obligations throughout our supply chain. Through sustainable procurement, we aim to improve working conditions and contribute to environmental protection. We maintain close dialogue with our suppliers and pursue a collaborative approach to achieving progress together.

  • 100 % integration of the Supplier Code of Conduct into procurement procedures.
  • Sustainability criteria are systematically incorporated into tenders. In prioritised procurement procedures, at least 10 % of the evaluation matrix has been allocated to sustainability criteria since 2025.
  • Supplier dialogue and internal training and awareness-raising activities to support sustainable procurement.
  • Risk management and complaints procedures established in accordance with the German Act on Corporate Due Diligence Obligations in Supply Chains (Supply Chain Due Diligence Act).
  • BVG Declaration of Principles on Human Rights (in German)

Our Passengers

By providing reliable, safe and, wherever possible, accessible mobility every day, we contribute to social participation in Berlin. Customer satisfaction, safety, and non-discriminatory access to public transport are at the heart of our approach.

  • Around 1.1 billion passenger journeys in 2025.
  • Approximately 95 % of Berlin's population live within 400 metres of a BVG stop or station.
  • Today, 86 % of underground stations are step-free, and the same proportion are equipped with tactile guidance systems for people who are blind or visually impaired. This is a key step and an incentive for us to continue expanding accessibility.
  • Investments in safety and cleanliness, as well as new safety concepts across the BVG network.
  • Measures to improve reliability, passenger information and service quality.

A more comprehensive picture of BVG's activities across the three dimensions of sustainability is provided in regular progress reports and as part of the German Sustainability Code (DNK).

As Germany’s largest public transport company, sustainability is a very important issue for the BVG. We take responsibility for the environment, for our own employees, for society and for our value chain. To this end, we have set up processes in accordance with the requirements of the German Supply Chain Sustainability Act (LkSG).

Our Human Rights Officer is responsible for monitoring and developing our human rights risk management system and reports regularly to the Executive Board. The Human Rights Officer is supported by specialists in the areas of occupational health and safety, environmental protection, purchasing and legal and compliance.

The procedure for managing LkSG-relevant complaints is described below. The requirements of the Whistleblower Act are followed throughout the process, especially regarding the independence and confidentiality of those processing complaints. Whistleblowers can also submit complaints anonymously under the LkSG. We aim to keep the processing time as short as possible and–if desired–to remain in contact with the whistleblower throughout the process and provide information in a clear and comprehensible manner. We comply with data protection legislation. The effectiveness of our complaints procedure is regularly reviewed.
