${CO_2}$ is plentiful in Martian atmosphere. $H_2$ can be produced on Mars using sunlight and can be reacted with $CO_2$ to form $H_2O+C$, or $CH_4+H_2O$.
Is it a feasible chemical reaction?

$\begingroup$ One has to either bring H2 from Earth or extract it from underground water ice which is much more laborsome to find and dig up than to just pump CO2 from the atmosphere. $\endgroup$– LocalFluffAug 10, 2015 at 8:08

Is production of methane possible on Mars?
Yes, via the Sabatier process. This has been proposed multiple times as a type of in-situ resource utilization on Mars. All that's needed is energy (e.g., sunlight), CO2, and hydrogen. The first two are easily obtainable. Except near the poles, the last is a bit of a challenge.
