At the dawn of Gravitational Wave Astronomy, new avenues have been opened to test and constrain cosmological models. By simulating standard sirens detected by the third generation ground-based gravitational wave detector, Einstein Telescope, we show how we one can discriminate among different cosmological models. In this work, we use 10-year projected data of Einstein Telescope to compare the standard cosmological model (the Lambda CDM) with models using different phenomenological parametrizations of the equation of state for the dark energy.
