Abstract: We prove the exactness of a descent sequence relating the algebraic cobordism groups of a scheme and its envelopes. Analogous sequences for Chow groups and K-theory were previously proved by Gillet. As an application, we prove that the $ K$-group of a scheme can be obtained from its cobordism group by extension of scalars.
