Green ban

A green ban is a form of strike action, usually taken by a trade union or other organised labour group, which is conducted for environmentalist or conservationist purposes.

Green bans were first conducted in Australia in the 1970s by the New South Wales Builders Labourers Federation (BLF). Green bans were never instigated unilaterally by the BLF, all green bans were at the request of, and in support of, residents' groups. The first green ban was put in place to protect Kelly's Bush, the last remaining undeveloped bushland in the Sydney suburb of Hunters Hill. A group of local women who had already appealed to the local council, mayor, and the Premier of New South Wales, approached the BLF for help. The BLF asked the women to call a public meeting, which was attended by 600 residents, and formally asked the BLF to prevent construction on the site. The developer, A V Jennings, announced that they would use non-union labour as strike-breakers. In response, BLF members on other A V Jennings construction projects stopped work. A V Jennings eventually abandoned all plans to develop Kelly's Bush.

The BLF was involved in many more green bans. Not only did the BLF represent all unionised builders' labourers in the construction industry; but the BLF also influenced the opinion of other unionised construction workers, and acted as a political leadership of the construction unions in the era. Forty-two bans were imposed between 1971 and 1974. Green bans helped to protect historic nineteenth century buildings in The Rocks from being demolished to make way for office towers, and prevented the Royal Botanic Gardens from being turned into a carpark for the Sydney Opera House. The BLF stopped conducting green bans in 1974 after the federal leadership under Norm Gallagher dismissed the leaders of the New South Wales branch.
