  Recent calculations of EDMs of light nuclei in the framework of chiral
effective field theory are presented. We argue that they can be written in
terms of the leading six low-energy constants encoding CP-violating physics.
EDMs of the deuteron, triton, and helion are explicitly given in order to
corroborate our claim. An eventual non-zero measurement of these EDMs can be
used to disentangle the different sources and strengths of CP-violation.
