I would like to also recommend Accoya, a modified Radiata Pine, as a high-performance and highly sustainable material cladding option. Accoya is a Cradle to Cradle Gold Certified, is food grade safe, and offers a 50 year warranty for above ground applications - 25 years with ground-contact. The Radiata Pine has an average seed to harvest cycle of 28 years, and once Acetylated, offers a 60 year expected lifespan.
LCA data can be found here. Happy to share more info if that could be helpful.
