A copolymer may include ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. Embodiments may also be directed to curable polymer compositions, expandable polymer compositions, articles, cured articles, and expanded articles formed from or including such copolymers of ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. A process for producing an ethylene vinyl acetate copolymer may include polymerizing ethylene at least partially obtained from a renewable source of carbon with vinyl acetate to produce the ethylene vinyl actate copolymer.
