Toitū Net Carbonzero Certification 2026

Campbell Brown Planning is proud to have successfully achieved our seventh year of Toitū Net Carbon Zero certification, a science-based programme accredited to internationally recognised ISO standards.

As part of the certification process, our greenhouse gas emissions inventory was independently verified, with total emissions for the reporting period of 18.81 tCO₂e.

Recertification reflects our ongoing commitment to measuring, managing, and reducing our environmental impact. Sustainability remains one of our core values and is embedded in both our planning practice and day-to-day operations.

This latest recertification reinforces our commitment to transparency and accountability, providing a trusted and independently verified framework for reporting our environmental performance and supporting meaningful climate action.

To offset our remaining emissions, we have purchased verified carbon credits through approved projects that deliver environmental and community benefits.

A special thank you to Lisa Watson and Isobel Lee for coordinating the collection and reporting of the data required for this year’s audit, and to the wider team for their ongoing commitment to sustainable business practices.

We also thank Toitū Envirocare for their continued support and independent verification of our emissions reporting and reduction journey.
