Aotearoa is going carbon neutral by 2050.

We are too.

The architecture industry is at an hour of reckoning. When we talk about climate change, there can be no ignoring the fact that building construction is a major culprit – and that the industry as a whole is largely self-serving. We’re part of the problem, which makes it our problem.

But it’s also a challenge. A challenge that calls on the very stuff we hang our hats on: ingenuity, creativity, and a commitment to making an ultimately positive impact on Aotearoa’s built environment.

RTA Studio is already accredited by Toitu as a carbon neutral company. So, when we say our ambition is to match government targets, we’re talking about the real stuff – the buildings we design for our clients.

To be clear, there are two types of carbon we’re talking about here.

Operational carbon – the carbon associated with operating a building, such as electricity.
Embodied carbon – the carbon associated with the production of materials used to build a building, like steel or glass.

We’re tackling both.

We’ll kick things off by selecting a benchmark building – a 2020 project that reflects where we’re at right now. Then, to track our progress, we’ve set ourselves three milestones.

To reduce the carbon footprint of our projects by an average of:

  • One third by 2030
  • Two thirds by 2040
  • 100% by 2050
