The Green Party of BC promotes the principles of participatory democracy, sustainability, social justice, respect for diversity, ecological wisdom, and nonviolence.

During this period, its internal politics were dominated by a compromise faction led by electoral reform activist Steve Kisby.

However, this period of relative stability ended with the party's failure to make a breakthrough in the 1991 provincial election, despite increasing its province-wide vote share to 0.86% and fielding a slate of 42 candidates.

He managed to take the party to running close to a full slate in the 1996 election, but was only able to garner only 2% support province-wide, despite receiving the endorsement of prominent environmentalist David Suzuki.

Parker's first term (1993–96) was characterized by near-continuous touring of rural BC which had, up to that point, negligible or highly intermittent organization outside of the Okanagan and Comox Valleys.

This touring paid off in yielding on-going organization throughout the province, enabling the party to come just four candidates short of a full slate.

During Parker's second term as leader, the party rose to a peak of 11% in public opinion polls between 1996 and 1999, almost exclusively at the NDP's expense.

While remaining sharply critical of Glen Clark's NDP government, Parker spearheaded highly controversial negotiations to form municipal electoral alliances with NDP-affiliated parties in 1998 after vote-splitting all but wiped out leftist representation at the local level in Vancouver and Victoria in 1996.

With the high-profile changes at the top, the party was able to improve on its 9% poll standing at the beginning of 2000 and reached 12% of the popular vote in the May 2001 provincial election.

In spite of that significant support, it won no seats in the provincial legislature – a fact which has been cited as an argument against the first-past-the-post voting system used in BC elections.

Following the failure of her preferred Free Your Vote, Carr focused her energy on a lively province-wide campaign opposing the 2010 Winter Olympic Games bid.

Between 2003 and 2005, the party's presence was notably low key as Carr returned to the constant touring mode that had characterized Parker's first term.

In the federal election of 2004, former Social Credit Member of the Legislative Assembly (MLA) and media personality Rafe Mair confounded many by openly supporting the Green Party.

In 1991, the party's strongest showing was 4.4% in Rossland-Trail; in 1996, 11% in Nelson-Creston, in 2001 and 2005, in Carr's riding of Powell River-Sunshine Coast where she received 27% and 25% respectively, and in 2009 in West Vancouver-Sea-to-Sky with 22%.

The Green Party signed a confidence and supply agreement with the NDP in exchange for policy concessions on environmental and social issues.

The electoral district of West Vancouver-Sea to Sky was originally called for Green candidate Jeremy Valeriote; the winning margin was small enough to trigger an automatic judicial recount.
