Whether traveling or not, you are required to always have your Green Card in your possession.
Section 264(e) of the Immigration and Nationality Act:
Every alien, eighteen years of age and over, shall at all times carry with him and have in his personal possession any certificate of alien registration or alien registration receipt card issued to him pursuant to subsection (d). Any alien who fails to comply with the provisions of this subsection shall be guilty of a misdemeanor and shall upon conviction for each offense be fined not to exceed $100 or be imprisoned not more than thirty days, or both.
And from the DHS
U.S. Citizenship and Immigration Services website:
If you are a permanent resident age 18 or older, you are required to have a valid Green Card in your possession at all times.
