Mott MacDonald signs global net-zero carbon commitment

28 August 2020


The global engineering, management, and development consulting firm is one of 100 businesses, organisations and governments from around the world to committed to net zero carbon buildings by 2030. 

Warner Brunton, Mott MacDonald’s Technical Director responsible for Sustainability and Building Services in New Zealand, writes about what this commitment means for the firm here in Aotearoa.

Signing up to the World Green Building Council's net-zero carbon commitment aligns with our commitment to deliver carbon neutral operations by the end of 2020. As with the rest of Mott MacDonald’s global business, in New Zealand we are already actively reducing our carbon footprint using digital technology, switching our transport modes and reducing travel, driving tenancy energy, water and waste reduction strategies and adopting sustainable services and consumables procurement policies.

Mott MacDonald's Auckland offices occupy level two of the 6 Green Star Mason Bros. building.

The purchase of renewable energy is a factor, but this has to be underpinned in the first instance by demand reduction. Occupying a high-performance tenancy and building is part of this approach. As a carbon offsetting strategy we are partnering in a native/indigenous vegetation afforestation project with Mana Whenua in Auckland which will have wider cultural, environmental, social and economic benefits. In addition, our landlord Precinct Properties recently received Toitū carbonzero certification across its property portfolio.

We are already embracing and advocating for low carbon design, delivery and operation with clients and on projects in each of the sectors we are working with including water, transport, buildings and through our advisory team. Our Moata digital twin platform is helping to deliver targeted and meaningful measurable carbon reduction opportunities across a range of public and private sector projects.

In the buildings sector we see fully integrated performance focussed and regenerative design, soft landings and continuous tuning as key to delivering operational carbon reduction. Ultimately, we believe that measurement and mandatory disclosure of operational performance in New Zealand, including using tools like NABERSNZ, will be a game changer on our path to net zero carbon. We watch with interest the building code review and consultation currently being carried out by MBIE and welcome discussion on mandatory carbon measurement and reporting.

Beyond all of this we continue to support our clients, work with industry and our peers to raise awareness and encourage action to deliver on net zero carbon. Committing to net-zero carbon buildings by 2030 is an important step, and one we urge everyone get on board with.
