Procurement

The public sector procures a wide range of products and services, including the construction and maintenance of roads and public buildings, vehicles, food for schools and canteens, workwear, IT equipment and much more. If federal, regional and local authorities consider sustainability aspects when purchasing goods and services, this has an impact on climate change mitigation, environmental quality, resource conservation and fair working conditions. These authorities also serve as a role model for purchasing departments in the private sector: as major consumers, their decisions to buy environmentally friendly products and services can point the way towards more sustainability.

The Oeko-Institut supports sustainable procurement at multiple levels: for example, it is involved in formulating a clear policy framework, developing strategic procurement strategies with targets and actions for reducing environmental footprints, and assessing how actions taken have contributed to climate change mitigation and resource conservation. Its researchers develop criteria and verification procedures for equitable, eco-friendly public procurement and work with public authorities and local experts in an international context on developing product-specific environmental criteria for green public procurement.

  • Infographic from Öko-Institut e.V. titled "What does socially just climate protection mean?" showing strategies for sustainable, socially acceptable climate protection. Central box labeled "Socially Just Climate Protection" connects to three approaches:  Income support (short-term):  Includes transfer payments, climate dividends, and energy payments.  Price adjustments (short-term):  Includes CO₂ levy, reduction of renewable energy levy, and modernization levy.  Reduction in energy consumption and emissions (long-term and lasting):  Split into two areas:  Energy efficiency / renewable energies: building renovation, heating system replacement, climate-friendly mobility.  Behaviour / use: energy-saving advice and sufficiency.  Silhouettes of diverse people are shown at the bottom, representing the inclusive impact of these measures.

    The twelve largest German chemical parks generated 23 million tonnes of CO2 (mt CO2) in 2022, which corresponds to three percent of German greenhouse gas emissions.
  • Coastal Ecosystems: Blue Carbon Storage

    Image05/29/2024
    Seagrass meadows, mangrove forests and salt marshes can absorb and store up to 216 million tons of carbon from the atmosphere worldwide every year. Over centuries to millennia, they form an enormous carbon store of up to 22,000 million tons of carbon in marine sediment. At the same time, they make an important contribution to the preservation of biodiversity in the oceans and on the coasts, help to protect against storm surges and coastal protection and thus contribute to the nutrition and safety of millions of people. This is shown in a research report by the Öko-Institut and the Leibniz Center for Tropical Marine Research commissioned by the German Environment Agency, which examines the importance of coastal ecosystems for global climate protection.
