Toitū carbonreduce Product Certification - Sustainably Leading the Industry


We're committed to reducing our carbon emissions and environmental impact for a sustainable future, by actively working towards reducing our carbon footprint.

What is the Toitū Certification? 

Established in 2001 as a government-owned Crown Research Institute, Toitū provides independent advice to help businesses measure, manage and reduce their carbon footprint and operate more sustainably. With certifications grounded in science and aligned with international standards like ISO14067:2018, giving you the confidence that these certifications are recognised locally and in most international markets. 

Toitū carbonreduce: Making a Difference

Our journey towards sustainability started with measuring our emissions in 2016, followed by strategic planning for decarbonisation.

Our commitment to reducing our environmental impact is evident in our product footprint. While the global average carbon footprint for aluminium extrusion is 11.5kg of CO2e per kg, OMEGA® has achieved an impressively low 1.29kg of CO2e per kg on a Scope 1 and 2 basis, with a full lifecycle of just 7.73 CO2e per kg verified through Toitū's carbonreduce certification.

Continuous Improvement Through Certification

Toitū enviromark diamond certification demonstrates our self-sustaining environmental management system, ensuring ongoing compliance with environmental regulations and a commitment to reducing negative impacts on the environment.

With our Toitū certifications, OMEGA® Windows and Doors ensures that our sustainability efforts are credible, consistent and compliant with international standards.

Scope 1 & 2 Emissions

As part of our commitment to produce low carbon aluminium products, we measure all our scope 1 & 2 emissions, and make every effort to keep these emissions to a minimum in our day to day operations.  

Scope 1 emissions

Emissions that come directly from the company, including emissions from transport to do with the businesses operations, as well as manufacturing and processing emissions. For example fuel combustion in boilers, furnaces and vehicles.

Scope 2 emissions

Scope 2 emissions are indirect emissions from purchasing power to run business operations. This could be from electricity, steam and greenhouse gas emissions related to heating and cooling of facilities.
