The Green Care Performance Calculator, developed by Werner & Mertz Professional and promoted by Green Key, is a free tool designed to help businesses measure and certify their environmental impact from using sustainable cleaning products. It aims to support companies in quantifying their annual savings in CO₂ emissions, plastic, and crude oil, thereby promoting transparency and accountability in sustainability efforts. 

The tool is useful for businesses across various sectors such as hotels, industry, public facilities, and catering services. It provides a quick initial estimate and a detailed certified report, which includes a personalised certificate featuring the company’s logo. This certificate can be used for internal reporting or to strengthen bids in public tenders and green procurement.  

To receive a certificate, registration is required via the link provided on the left-hand side of the platform.
