A method of sequestering at least one target species, including exposing a proppant for use in subterranean hydrocarbon recovery via hydraulic fracturing, which comprises a material adapted to sequester the at least one target species formed external to the subterranean formation and formed external to the proppant and the material, prior to injecting a fluid comprising the proppant into a subterranean fracture, or exposing the material of the proppant to the at least one target species prior to completing formation of the proppant, whereby the at least one target species is sequestered within the subterranean formation via sequestration of the target species within the injected proppant.
