Hamburger Klimaschutzstiftung für Bildung und Nachhaltigkeit

What Hamburger Klimaschutzstiftung für Bildung und Nachhaltigkeit does

The Hamburger Klimaschutzstiftung für Bildung und Nachhaltigkeit is a charitable foundation (Stiftung bürgerlichen Rechts) founded in 2012 and headquartered at Gut Karlshöhe in Hamburg, Germany. It operates a 9-hectare environmental learning and experience center hosting approximately 1,000 events per year on climate, energy, biodiversity, and sustainable consumption. The foundation coordinates the Hamburger Masterplan BNE 2030 (Education for Sustainable Development) on behalf of the Hamburg government across six educational forums spanning early childhood, school, vocational, higher education, extracurricular, and district-level education. Core programs include Klimaschule PLUS (98 schools certified for 2025-2026), Energie4Bildung and Energieberatung für Klimaschulen (energy education and operational consulting), the #moinzukunft Hamburger Klimafonds (grant program for non-profit Hamburg climate initiatives, €1,000-€20,000 per project), a Weltklimakonferenz student simulation, venue rental with Hobenköök catering, a Freiwilliges Ökologisches Jahr (FÖJ) volunteer program with ANU, and donations/corporate engagement.

Revenue is structured around three streams: government grants from the Hamburg Authority for Environment, Climate, Energy and Agriculture (BUKEA) covering the Masterplan BNE 2030 (€262,000 in 2025), the Klimafonds (€200,000-€400,000 in prior rounds), and Klimaschule-related programs via the Hamburger Klimaplan; individual and corporate donations managed by a dedicated Fundraising Manager and processed via FundraisingBox; and venue rental income from nine rooms (38-354 sqm) at Gut Karlshöhe. School programs are free of charge for Hamburg schools, while venue pricing is quote-based and Klimafonds grants require a 10% co-funding contribution. With 18 employees led by Managing Director Andje Stamer, the foundation serves Hamburg schools, kindergartens, families, civil society initiatives, and corporate event clients, distributing services through direct in-school delivery (coordinated with LI and Schulbau Hamburg), the Gut Karlshöhe physical venue, and a self-serve Klimafonds application portal.

The foundation uses no proprietary technology platform. Its digital stack consists of Matomo for privacy-compliant web analytics, FundraisingBox (Wikando GmbH) for donation processing with SSL encryption, embedded YouTube videos, Google Maps, and the Bike Citizens bicycle route planner. Distribution relies on direct engagement at Gut Karlshöhe, in-school delivery by Klimaberater:innen, institutional coordination with BUKEA/LI/Schulbau Hamburg, and institutional email channels for the Masterplan BNE 2030 ([email protected]) and Klimafonds ([email protected]).
