In all fields, environmentally friendly and recyclable materials, such as wood, stone, and paperboard, were extensively used, and high environmental standards were set for all sponsors and suppliers.
Kõikidel aladel kasutati rohkesti keskkonnasõbralikke ja uuestikasutatavaid materjale, nagu puu, kivi, papp, ning kõigile sponsoritele ja varustajatele seati kõrged keskkonnakaitse nõuded.
