Carr has been the BC Green Party leader on two separate occasions. She was the party's leader (although called a spokesperson because the Party did not have leaders at that time) in the 1983 provincial election, held shortly after the party's founding. Carr ran in the two member riding of Vancouver-Point Grey, and finished last in a field of eight candidates with 1549 votes. She also ran as a Green candidate for the Vancouver School Board in 1984, but after this, besides maintaining her membership, she had little further involvement with the provincial Green Party until the late 1990s. Although she and her husband Paul George returned briefly to active involvement in the late 1980s.
