He has advised clients on international treaty obligations applicable to the transboundary movement of mercury and other hazardous wastes, and has managed local counsel examining environmental laws in Central America and Europe applicable to the transboundary movement of such wastes.

Steve’s broad experience representing environmental clients led to his work on government law and policy matters.
