Create actual sustainable products that sell

The only training you need to take responsibility and improve your environmental impact

Calculate your product footprint step by step

The only training you need to take responsibility and improve your environmental impact in fashion’s supply chain.

We need sustainable solutions that everybody loves. Sustainable products and services should be of high quality, highly desirable, and convenient—all in one. Through clever innovation, you can add value and, at the same time, reduce the environmental burden. The key challenge here is the ratio of low environmental impact with a high value of the product.

In other words, we need a new norm for sustainability. Highly transparent, fact-checked, measured, compared, and calculated. Our industry can do much better. We need a radical change, and we are here to help you to make it happen.

Professionals who did this course

Juliana Marques

The Footprint masterclass enabled me to understand what a footprint is and how to measure the life cycle of products in an easy way. The course is really practical because of the exercises that support the theory and the tools. On a daily basis I develop new products, and to develop new products on basis of their environmental impact was an eye-opener to me. It helps me to communicate the sustainable benefits of a product, make more informed decisions, and chose more sustainable materials instead: because it's measurable now.

We didn’t know anything about LCA, but this course is a great experience and satisfied our needs for structured and easy-to-digest knowledge. There are great examples that explained the theory in real practice and information is explained step by step. Now we know the definition of an LCA, how to perform an LCA and how to judge the outcome. The training is both very professional and personal. Our eyes are opened after this amazing course and we are able to serve and inform our customers in a better way.
