Reduction of energy consumption and GHG emissions
Adler Group emits greenhouse gases primarily through heating for tenants (Scope 3), office operations, fleet (Scope 2), and building material procurement (Scope 3). In 2022, a GHG reduction program was launched to address climate concerns and potential tax implications. Key areas of focus include upgrading heating technology, fleet, and using eco-friendly materials. Economic constraints led to portfolio consolidation, delaying some efforts. Post-transformation, a revision is planned. Initial goal: 50% GHG reduction by 2030 (based on 2020 levels), with measures postponed.
The property portfolio as of 31 December 2023 contains 25,043 units. At the end of 2023, the heating consumption was c.130 kWh/m2, which is lower than last year. The electricity consumption stood at 3.15 kWh/m2 and energy intensity was 142.15 kWh/m2. The GHG emission was 2.05 tonnes CO2/m2, volume of water used was 3.60 m3/m2 and volume of waste was 237,681 m³/year. Latest figures are available in the integrated annual report.
The GHG reduction strategy involves enhancing energy efficiency and lowering emissions intensity. Structural refurbishments and energy-related upgrades are key components. Adler Group's subsidiary, Adler Energy Services, manages energy procurement. Financial changes and portfolio restructuring delayed the plan's execution, but the 2030 targets remain intact. The plan will be revised based on reliable data and adjusted post-restructuring. Limited progress was made in 2022 and 2023 due to tenant behaviour changes influenced by rising energy prices.
Projects for environmental protection
Until 2021, Adler Group engaged in project development, focusing on sustainable practices and aiming for certification from agencies like DGNB, LEED, or BREEAM. In 2023, completed projects for third parties met customer specifications, closely aligning with Adler's sustainability standards. Initiatives like optimizing waste collection areas with solar-powered lighting were implemented, yielding positive results. In Berlin, a hydrogen-powered fuel cell is being tested for heating and hot water production, with results expected in 2024. A property in Berlin serves as a testbed for various energy-efficient technologies and measures to gauge their effectiveness and cost-efficiency for reducing GHG emissions.
Sustainability within the Company's organisation
Adler Group aims to continually reduce electricity, heat, and fuel consumption across its operations, guided by an ISO 50.001-certified energy management system. At office locations, focus lies on energy-efficient equipment and centralized offices in Berlin. Vehicle fleet management targets reduced fuel consumption and greenhouse gas emissions, with 396 vehicles in 2023. Measures include optimizing driving behavior and transitioning to hybrid and electric vehicles. Employees are encouraged to use company bicycles or cargo bikes where feasible.
Adler Group's Purchasing department guides goods and services procurement, emphasizing sustainability. Minimum sustainability requirements were enforced from 2023, with sustainability performance monitored. The purchasing catalog includes sustainable alternatives alongside conventional options, covering building materials, office supplies, vehicles, and services. Strategic partnerships are sought to develop sustainable products, aiming to innovate and drive sustainability in real estate procurement.
