Core offering

The Alliance for Sustainable Schools is a non-profit membership organization that helps international K-12 schools address systems-level sustainability challenges across five areas: campuses, transport, food, uniforms, and education. Schools join by signing the eight-pledge Sustainable Schools Charter and gain access to a member network, sustainability resources, professional development, student internships, an endorsed supplier directory, and signature events such as the Sustainable Behaviour Change Hackathon and Sustainable School Food Summits.

Product overview

The Alliance for Sustainable Schools (TASS) is a non-profit organization operating as a community of practice for sustainability in schools. Rather than a traditional product company, TASS offers a membership-based network centered on the Sustainable Schools Charter—a framework of eight pledges covering campus sustainability, transport, food, uniforms, and education. The organization provides member schools with networking opportunities, a directory of endorsed suppliers, sustainability resources, professional development, and student internship placements. TASS also organizes signature events including the Sustainable Behaviour Change Hackathon and Sustainable School Food Summits. Through affiliate partners like Dress Green and Class Of Your Own, TASS connects member schools with specialized programs such as uniform recycling (UNI Green Program) and sustainable built environment education (Design Engineer Construct!).

Direct peers

• Jane Goodall Institute - Roots & Shoots: Direct peer - Roots & Shoots is a youth-led community action and environmental education program operating in K-12 schools globally. Like TASS, it combines a charter/framework with student-led projects and a school-based network model.
• Eco-Schools (Foundation for Environmental Education): Direct peer - Eco-Schools is the most established international sustainability education program for K-12 schools, awarding Green Flag certifications to participating schools. TASS member schools (e.g., Aiglon, Deira International) also pursue Eco-Schools, making it the closest comparable offering in the same niche.
• LEAF (Learning About Forests): Direct peer - LEAF is a school-based environmental education program operated under FEE, with similar charter/network structure for international K-12 schools focused on sustainability topics.
• Ashoka Green Schools: Direct peer - Ashoka's Green Schools program supports school communities in becoming agents of environmental change, with similar network-of-schools structure and sustainability framework focus.

Emerging players

• Green Schools National Network: Emerging player - US-focused K-12 sustainability network with member schools and practitioner community. Comparable peer in target customer (K-12 schools) and theme (sustainability) but geographically narrower than TASS's Asia-Pacific/Middle East footprint.
• Carbon Literacy Project: Emerging player - Provides Carbon Literate Organisation certifications to schools (e.g., CIS Bronze level cited by TASS member). Overlapping audience and complementary offering, but product (training/certification) rather than full sustainability charter.
• Micro Schools Network: Emerging player - TASS affiliate partner serving 320+ member micro schools globally. Operates a similar membership directory/community model for a related (smaller-school) niche, providing a partial overlap in customer base and GTM.

Broad incumbents

• LEED for Schools (U.S. Green Building Council): Broad incumbent - USGBC's LEED certification program covers school buildings and overlaps with TASS's "sustainable built environment" pillar. Operates at much larger scale but addresses one of TASS's five focus areas rather than the full charter.
• Sodexo School Services: Broad incumbent - Sodexo is a global school food caterer that TASS has engaged as a partner on sustainable menus. Comparable customer base (K-12 schools) and adjacent sustainability agenda, but operates as a service provider rather than a sustainability framework.

Others

• Class Of Your Own (COYO): Others - COYO is a UK social enterprise that develops and delivers the DEC sustainability curriculum that TASS distributes to member schools. Comparable audience and complementary offering, with COYO providing curriculum while TASS provides the school network.
