Today, there is a wide variety of methods to assess companies’ impacts on society, people, and nature. Our goal is to create a standardised method to ensure greater sustainability, transparency and comparability in business. We are developing this method in iterative steps. During the last year, we have created version 0.1 of the method and tested it in our member firms. The feedback of our members was published in our first pilot study in May 2021 and will be incorporated in version 0.2 of our impact valuation method. Version 0.1 of our papers comprises four papers: The General Method Paper, two papers on environmental and socio-economic impact, and the extended input-output modelling.
