RMM Renews Toitū Carbonreduce Certification with 24% Emissions Reduction

Jul 09, 2025
We are proud to announce that Rough Milne Mitchell Landscape Architects has successfully completed its second year of Toitū carbonreduce certification.
Following our latest annual audit, we have achieved a total emissions figure of 37.10 tCO₂e — representing a 24% reduction from the previous year’s total of 48.77 tCO₂e. This year’s result also reflects a 0.76 tCO₂e/$M decrease in emissions intensity, based on a two-year rolling average.
These results mark a meaningful step forward in our sustainability journey, and demonstrate our commitment to reducing our environmental impact across all areas of our practice. From reducing travel-related emissions to improving energy use and waste management, we’re proud to be part of a collective shift toward more responsible business.
Our Toitū carbonreduce certification is valid until September 2027, with continued annual surveillance audits and reviews ensuring we stay on track. This certification reflects not only our current performance, but our long-term dedication to climate-positive action.
We’d like to acknowledge the support of our team, clients, and collaborators for embracing sustainable approaches and helping embed environmental responsibility into our daily operations.
For those looking to take similar steps, we encourage you to visit the Toitū website and explore what’s possible. You can also follow the conversation using #ToituTogether across social media.
