  In this work we use cosmography to alleviate the degeneracy among
cosmological models, proposing a way to parameterize matter and dark energy in
terms of cosmokinematics quantities. The recipe of using cosmography allows to
expand observable quantities in Taylor series and to directly compare those
expansions with data. We adopt this strategy and we propose a fully
self-consistent parametrization of the total energy density driving the late
time universe speed up. Afterwards, we describe a feasible \emph{cosmographic
dark energy model}, in which matter is fixed whereas dark energy evolves by
means of the cosmographic series. Our technique provides robust constraints on
cosmokinematic parameters, permitting one to separately bound matter from dark
energy densities. Our cosmographic dark energy model turns out to be one
parameter only, but differently from the $\Lambda$CDM paradigm, it does not
contain ansatz on the dark energy form. In addition, we even determine the free
parameter of our model in suitable $1\sigma$ intervals through Monte Carlo
analyses based on the Metropolis algorithm. We compare our results with the
standard concordance model and we find that our treatment seems to indicate
that dark energy slightly evolves in time, reducing to a pure cosmological
constant only as $z\rightarrow0$.
