Abstract: In this note we prove that a polynomial mapping T in two real variables such that its jacobian is constant (the so called planar real Cremona maps) is a bijection between R2 and R2. Let (F,G) be the polynomial components of T. We give a complete global picture of the family of curves F = constant and G = constant.
