As designers and educators we find that without an ability to calculate the carbon footprint of our work in industry, it is extremely hard to know that we are making the right decisions in terms of design/sourcing/logistics etc. See http://www.kering.com/en/sustainability/methodology.
Currently there are no tools available either by open-source or by subscription, only methodologies. If we are really to prevent environmental disasters and make the right shifts across all levels, working together and sharing tools like this is critical.
* Impact assessment tools should be available within schools, also not just in fashion!
