We believe in the power of togetherness to amplify change. We invite you to join us.

Warren and Mahoney has been a certified Toitū net carbonzero architectural practice since 2007. Over the past 10 years we have reduced the carbon intensity of our operations by more than 40%. Over the next 10 years, we are committed to maintaining our carbon-neutral status and reducing the carbon intensity of our operations by a further 50%.
By 2030, our goal – with our clients – is that all new projects designed by Warren and Mahoney will be net-zero carbon in operation, be 50% more energy efficient and have 40% less embodied carbon.
01 / Guiding Belief
Warren and Mahoney’s guiding belief is that every project has the potential to contribute positively to people’s lives, thriving communities and a flourishing natural environment. Our aim is to work together to bring this potential to life.
We support the World Green Building Council’s goal of all new buildings being carbon neutral in operation and have 40% less embodied energy by 2030.
We will use our influence and knowledge to advocate, educate and help improve the environmental performance of our industry.
02 / 2030 Vision
Climate Regenerative Design
By 2030, our goal – with our clients – is that all new projects designed by Warren and Mahoney will be net-zero carbon in operation, be 50% more energy efficient and have 40% less embodied carbon.
We will work with our consultant teams to model, measure and progressively improve the efficiency of our designs; offering our clients the opportunity to minimise their operational and embodied carbon emissions and meet their environmental aspirations.
We will support the development of sustainable design through reducing operational and embodied carbon emissions in line with the World Green Building Council’s Advancing Net Zero targets and the Bringing Embodied Carbon Upfront initiative. Warren and Mahoney actively endorses the NZGBC’s Net Zero Carbon Roadmap for Aotearoa’s buildings as well as supports the GBCA’s Carbon Positive Roadmap for Australia’s buildings.
Sustainable design, however, is more than just reducing carbon emissions. We have, therefore, also adopted ten sustainable design principles which allows us to work with our clients to set holistic, wide-reaching environmental goals for all of our projects.
Advocacy and Influence
We have been a certified Toitū net carbonzero business since 2007. Over the past 10 years we have reduced the carbon intensity of our operations by more than 40%. Over the next 10 years, we are committed to maintaining our carbon-neutral status and reducing the carbon intensity of our operations by a further 50%.
As designers of the built environment, the biggest positive impact we can make is through design. However, we also have a responsibility, as a business, to operate with lower emissions, support a sustainable supply chain and help staff and their families live less carbon intensive lives. We choose to offset our unavoidable emissions through regenerating native forests and by supporting developing countries to reduce their fossil fuel use.
We stand proudly as part of the Climate Leaders Coalition of New Zealand and as signatories of the Architects Declare Climate Emergency in both New Zealand and Australia.
