From 2025 all organisations in the EU of more than 250 employees have to develop and deliver Sustainability Reports manadatory by legislation. This huge endeavour needs preparation and networking by these public and not for profit organisations. The European Commission and governments will implement this directive this year. This yearly mandatory reporting will cover the whole value chain of your organisation: from transpartancy in your work force, affected communities, strategy, risk to different topics about the Green Sustainability of your organisation, covering climate change, pollution, water use, biodiversity, use of materials and circulairity. This is the focus of our project. We will establish a learning network with between public and not-for profit organisations and implement a sustainability office who is able to give advice to others.
