In today's world, schools face an increasing challenge to adapt to changing environmental and societal needs. The European Commission stresses the importance of transforming the school environment on active learning spaces for sustainabilityThese initiatives go beyond regular teaching and strive for the comprehensive integration of sustainability principles into all aspects of school life, from buildings to community engagement.

Basic principles and approaches

The common denominator of successful sustainability initiatives is holistic school approach, which includes governance, institutional practices, pedagogy and community engagement. Key principles include: participatory design, where students, educators and local communities are involved in planning and implementation, leading to a sense of ownership and responsibility. Emphasis is also placed on environmental sustainability (e.g. energy efficiency, renewable materials), well-being and inclusion (accessible and adaptive environments) and quality of architecture.

Innovative spaces and pedagogy

Several European initiatives are transforming traditional school environments into dynamic centers of sustainable learning:

• School Building Masterplan (Flanders, Belgium): This nationwide program modernizes aging infrastructure with a priority on sustainability, inclusion, and local needs. It integrates elements such as near-zero energy standards, green roofs, permeable surfaces and rainwater harvesting systemsExamples include the BuBaO Sint-Gregorius school, which created a low-stimulus environment for children with special needs, and the Talent School in Turnhout, which uses outdoor classrooms to improve student engagement.
• Cours Oasis (Paris, France): Initiative transforms traditional schoolyards into multifunctional, sustainable spaces with an emphasis on combating urban heat islands and managing rainwater. Co-design with students, educators, and families is key, and the courtyards serve as outdoor classrooms with garden workshops and other experiential activities. These yards are often open to the public on weekends, thereby strengthening community ties.
• Schools + Sustainable (Barcelona, Spain): This initiative supports schools in integrating sustainability through holistic approach and inclusionThe program helps schools transform spaces, such as playgrounds, that have become biodiversity hotspotsHe emphasizes that true transformation goes beyond just infrastructure and also requires a change in pedagogical and organizational approaches.
• CS Lewis Bilingual High School (Bratislava, Slovakia): The school focuses on innovative, experiential and practical pedagogyIt uses recycled materials and has photovoltaic panels on the roof, which cover almost a quarter of the electricity consumption. Spaces such as the Gallery, the reading room, the café “The Eagle and Child” and the community space “BARAKA” are designed to support learning, relaxation and community building.
• Gantofta School (Gantofta, Sweden): The school applies the principles circularity in the renovation of the premises. The old sports hall was converted into a flexible classroom, the locker rooms into music and art rooms, and the garage into a kitchen. Students are actively involved in climate data monitoring (air quality, energy consumption, food waste) and into projects such as designing recycling machines.
• GRG7 Kandlgasse (Vienna, Austria): The school has several green spaces including green roof, school garden, external and internal green walls and green corridorThese elements help reduce the urban heat island effect and improve indoor air quality. Although their potential for direct teaching is not fully exploited, students enjoy using them for play and informal learning.
• Liceo Keplero Roma (Rome, Italy): This school is part of the "Green School" initiative and is the only school in Rome to have green roofOther sustainable spaces include Summer (geometric bamboo structure), Geodome (ecological structure made of clay) and vegetable gardenStudents are involved in hands-on learning, scientific experiments and environmental monitoring, such as tracking waste sorting.
• School Sector Technical Roadmap for Climate Action 2023-2030 (Ireland): This national initiative focuses on decarbonization and energy efficiency of the school sector. It supports renewable energy sources (heat pumps, photovoltaic panels) and sustainable transport to schools. Programs like “Safe Routes to School” promote safe cycling and walking routes.

Key impacts and challenges

The impacts of these initiatives are far-reaching:

• Environmental benefits: Reduced energy consumption and carbon emissions, improved air quality, increased biodiversity and more efficient water management.
• Student well-being and inclusion: Improved satisfaction, thermal comfort, reduced conflict, increased interaction between the sexes and accessibility, leading to a sense of belonging.
• Learning outcomes and competences in sustainability: Development of critical thinking, problem solving, environmental literacy, practical skills, and student initiative.

Despite the positive results, there are challenges such as administrative complexity, lack of funding, need for systematic maintenance and initial resistance from stakeholdersThe keys to long-term success are systemic support, flexible approaches and integration of sustainability into school curricula.

These case studies studies show that sustainability learning environments are key to shaping the next generation that is not only environmentally aware, but also prepared to act and lead change towards a more sustainable society. JRi
