New Zealand is set to introduce mandatory carbon counting for the construction industry starting in 2025, marking a significant shift in the country’s approach to reducing the carbon footprint of new buildings.
This initiative is part of the government’s broader strategy to combat climate change, focusing on both embodied and operational carbon emissions associated with building materials.
From 2025, obtaining building consent will require a detailed report on the embodied and operational carbon of the project.
The government will collect and review these reports during the initial year to establish specific carbon caps that will apply from 2026 to 2030.
This proactive measure underscores the urgency of managing carbon emissions in the construction sector, which currently accounts for about 20 per cent of New Zealand’s emissions.
The new regulations will have significant implications for architects and builders, who will need to integrate carbon accounting into their project planning.
This includes using environmental product declarations (EPDs) to accurately report the carbon content of materials used.
Products with verified EPDs are likely to become more prevalent, as those without may pose compliance risks or incur higher costs due to additional verification processes.
To comply with these regulations, industry professionals can adopt several strategies:
- Integrate environmental assessments early in the design process
- Choose materials with lower embodied carbon and certified EPDs
- Implement innovative design approaches, such as designing for deconstruction and longer life spans
Technology will play a crucial role in adapting to these changes.
Building Information Modelling (BIM) and Life Cycle Assessment (LCA) software will become essential tools for predicting and optimising the carbon footprint of buildings before construction begins.
These technologies will enable professionals to perform comprehensive analyses of environmental impacts associated with building materials over their entire life span.
The mandatory carbon counting initiative is expected to transform the construction industry in New Zealand, encouraging more sustainable practices and innovations.
As the industry adapts to these changes, continuous learning and adaptation will be key to success.
For those in the construction and design sectors, embracing these changes will be essential as they navigate the challenges and opportunities presented by the new mandate.
This regulatory shift aligns New Zealand with global efforts to mitigate climate change impacts and positions the country as a leader in sustainable construction practices.
