Barry is the leading strong proponent of the Sutton to Sandycove coastal promenade (S2S) on DLRCoCo and has fought hard for gender and marriage equality; he is the only councillor to have drafted his own bye-laws to give effect to legal change on DLRCoCo. and is a strong advocate for change on the Council meetings.
