GreenCircle Product and Factory Certifications

GreenCircle is a leading, third-party certifier of sustainability claims. Through a rigorous evaluation process, GreenCircle provides validation and transparency that a manufacturer's product claims are authentic. Three series of Norton power operators and the Monroe, NC, facility have earned GreenCircle certifications.

The Norton power operators were verified to offer valuable energy savings as compared to similar products.

Operator Energy Savings
6000 Series 24%
5800 Series ADAEZ (plug-in) 91%
5800 Series ADAEZ (wireless) 100%


GreenCircle performed an audit of sustainable manufacturing practices at the Monroe, NC facility as compared to benchmark data from 2011. The Monroe facility was verified to have achieved the following improvements:

• 5% Carbon Footprint Reductions
• 17% Reduced Energy Usage
• 51% Reduced Water Usage
• 22% Reduced Waste to Landfill
• 83% Waste Diversion from Landfill

GreenCircle certifications are becoming increasingly desired by architects and end users alike, because they verify that the products contribute to facilities' sustainability objectives and LEED ratings.

These certifications join the Environmental Product Declarations (EPDs), Health Product Declarations (HPDs), ISO Certifications and Declare Labels that provide valuable sustainability information for the large majority of Norton door closers and operators. Certifications such as these help to validate and measure the effort ASSA ABLOY puts forth to reduce our environmental impact through more efficient production operations, while working to create more energy-efficient product innovations.
