The Green Building Council Australia (GBCA) – home of the Green Star building rating system – is seeking industry consensus on long-term action to reduce carbon emissions.

The GBCA has just released a discussion paper (PDF, 1.2MB) as a first step towards a new Carbon Positive Roadmap for the Built Environment.

Feedback on this paper is invited from any interested stakeholders, with submissions closing on April 28.

Carbon neutral goals

Specifically, GBCA has built on the targets outlined to meet Australia’s commitments to the Paris Agreement and to keep global warming to within 2.0 degrees Celsius.

The goals:

  • All new buildings must be net zero by 2030
  • All existing buildings must be net zero by 2050.

The Council proposes a three-step process to achieve these targets:

  1. Address the leaders in the market, such as those who use Green Star.
  2. Engage with professionals, the supply chain and occupants.
  3. Advocate long-term structural changes in the built environment.

Why the built environment matters

The GBCA notes that, despite the successes of its advocacy and the Green Star rating programme, across the wider industry carbon emissions continue to rise.

The built environment’s current share of the carbon emissions is significant – around a quarter (23%) of Australia’s greenhouse emissions. So the property and construction industry has a central role to play in meeting these targets.

Transport (17%), industrial energy use (23%), and waste (2%) are also areas that the building industry contributes to, and influences, through its supply chains, transport choices and resource efficiency choices.

Have your say

Throughout the discussion paper you will find questions and spaces for your responses. Make sure to send your submissions to greenstar@gbca.org.au by the April 28 deadline.
