We're working to reduce emissions from buildings during their construction and operation, and also ensure New Zealand's buildings are resilient enough to withstand changing climate conditions.
The challenges we're facing
The building and construction sector is a significant contributor to greenhouse gas emissions which are emitted when building materials are produced, building are constructed and energy is used in buildings during their operation.
If New Zealand is to reach its climate change goals, including net zero carbon by 2050, the building and construction sector must play its part.

The Building for Climate Change Programme
In order to help lower greenhouse gas emissions across the building and construction sector, the Building for Climate Change has developed two emissions mitigation frameworks:
Whole-of-life embodied carbon reduction
This framework proposes to set mandatory reporting and measurement requirements for whole-of-life carbon emissions, including from the materials used in construction, the construction process, construction waste, and the disposal of a building at the end of its life.

Transforming operational efficiency
This framework proposes to set required levels of efficiency for energy use and water use and define minimum indoor environmental quality measures for buildings.

We have consulted with both the public and industry experts on these two frameworks, and the summary of submissions report from this has been released, and is available to read in full.

We're also currently working on an Adaptation Framework for the building and construction sector.
As a result of climate change, many areas in New Zealand are expected to be subject to more extreme weather events which have the potential to impact on buildings and their occupants. This framework will set out key actions to help ensure New Zealand’s building and construction sector is able to respond to the impacts of climate change. It will focus on two key principles: not building in areas where climate change hazards are likely (e.g. subject to flooding) and ensuring design standards take into account our future climate (e.g. wind pressures and rainfall intensity).
The Building for Climate Change team are contributing to the development of New Zealand’s National Adaptation Plan, which is due to be published in August 2022.

What this means for New Zealand
The changes we're planning will help make homes warmer, drier and better ventilated, and provide a healthier place for us all to work and live. Buildings will be designed and constructed to use as little energy and water as practical, meaning less greenhouse gas emissions.
Once the programme is in place, energy efficiency and carbon emissions will become core considerations when building - just as important as cost and design. Reusing buildings and recycling materials will also be an important part of the building process, and we'll be working with local suppliers so they'll be able to gear up and support these product streams.
Building owners will understand their options, and what to ask for to get an efficient building with a low climate impact.
Our building and construction workers will have the right skills to design and build for energy efficiency, low embodied carbon and climate resilience.
