description A method and composition for reducing hydrogen sulfide generated or emitted from an asphalt composition are disclosed. In certain aspects, a method for reducing hydrogen sulfide emissions from an asphalt composition is provided wherein an additive is mixed with the asphalt composition and the additive is a copper-based complex. The asphalt composition can include asphalt and an asphalt modifying acid. The copper-based complex can comprise copper carboxylate. The copper carboxylate can be an oil-soluble metal organic.
