We feel it is important to consider the environment in all facets of our business and so measuring and monitoring our impact is the only way to understand how we can improve. Our measured carbon emissions will be offset, monitored and continually reduced through a variety of smarter business practices. Read more about our carboNZero manufacturing here.

All of our Mammoth polyester insulation products are Red List Free for both our thermal and acoustic insulation products.

The Living Building Challenge developed a Red List of prohibited materials under the Declare Programme to provide transparency around the building products. 

Declare is a ‘nutrition label’ for the international building industry and is a voluntary self-disclosure programme aiming for healthier and more ecological products in construction. Red List Free products are shown to be free from Declare’s red list of ingredients.

Eco Choice Aotearoa (formerly Environmental Choice New Zealand) is the official environmental labelling programme. This programme, which commenced in 1992, operates independently from the government but the label is government owned and endorsed. 

Since its commencement, the government has financially supported the scheme, both directly and indirectly. 

Most of our Mammoth insulation products are Eco Choice certified.

We are a member of the NZ Green Building Council demonstrating commitment to green building practices in NZ.
