These certifications are regularly audited and updated, providing consumers with reliable benchmarks for ethical purchasing.
Eco-Bricks is PETA-approved, meaning it does not conduct or commission any animal testing for its products. The brand’s bamboo model kits are entirely vegan, containing no animal-derived components such as glues, dyes, or adhesives. All packaging is also vegan-friendly, using recycled paper and soy-based inks.
The brand has committed to using 100% biodegradable or recyclable packaging by 2025, and already sources all materials from FSC-certified bamboo plantations. Eco-Bricks offsets its remaining carbon emissions through verified projects, and its 1% for the Planet pledge ensures ongoing support for environmental causes.

Eco-Bricks sources its bamboo primarily from family-run farms in China, where it partners with Fair Trade-certified cooperatives to ensure fair wages and safe working conditions. The brand publishes annual social audits on its website, detailing worker hours, pay equity, and compliance with local labor laws. Independent third-party inspections verify that no child labor or forced labor is used in the supply chain. The bamboo is harvested using methods that prevent soil erosion and promote reforestation.
