143Sustainability guidelines

143 Sustainability guidelines (1) The Minister must make guidelines (the sustainability guidelines) for the sustainable use of materials for building. (2) A builder must not use a building material in contravention of the sustainability guidelines. 1 The sustainability guidelines may prohibit the use of rainforest timber for new buildings or repairs other than repairs to things that already consist mainly of rainforest timber. If the guidelines did this, a builder could use rainforest timber to repair window frames made of rainforest timber, but could not put in an extension containing rainforest timber. 2 The sustainability guidelines may allow the demolition of a building containing material from an unsustainable industry, eg rainforest timber. If the guidelines did this, a builder could demolish such a building without contravening the sustainability guidelines. (3) The sustainability guidelines are a disallowable instrument.
