About Evidensia

Evidensia's mission is to put evidence at the heart of sustainability actions and decisions.

Informing action for a sustainable future

With growing commitment by governments and businesses to tackle sustainability challenges, there is a need for understanding what approaches work where, why and how. Evidensia helps you access and interpret credible research on the sustainability impacts and effectiveness of supply chain initiatives and tools. It provides a portal to information and evidence and supports shared learning through its insights and analysis.


Evidensia was founded in 2019 by ISEAL Alliance, Rainforest Alliance and WWF with the support of the Global Environment Facility. These organisations form the Coordination Committee that oversees implementation of the site and all related activities. Our Advisory Committee is made up of distinguished researchers, policymakers and business and NGO leaders who provide strategic advice on the site’s approach and support with its uptake, complementarity to other platforms and sustainability.

The current composition of the Advisory Committee is:

  • Christine Carey, Head of Knowledge and Learning, Alliance for Water Stewardship (AWS)
  • Pascal Fabie, Senior Learning and Knowledge Advisor, UN Development Programme (UNDP)
  • Laura Jungmann, Manager Sustainability, Albert Heijn
  • Sarah Lake – Director of  Supply Chain and Finance Transparency, Climate Advisers
  • Dr Gillian Petrokofsky – Researcher, Department of Zoology, University of Oxford
  • Aditi Sen, Senior Policy Advisor, Climate, Oxfam America
  • Darrel Weber, CEO, Roundtable on Sustainable Palm Oil
  • Joseph Wozniak, Head, Trade for Sustainable Development, International Trade Centre (ITC)

In addition to the founding partners, our other partners work to strengthen Evidensia by contributing and sharing content, identifying and filling knowledge gaps, providing strategic advice, helping connect Evidensia to other technology tools and raising awareness of the site.

Approach and Methodology

Evidensia follows an open source principle to sourcing content that is relevant and meets basic research quality norms. All credible content selected or submitted to the site is then organised based on our evidence typology so you can find what you need. In our online library  you will see transparent information about what category of evidence a specific resource belongs to that is determined by what type of research it is based on and how the study was designed. Where available, you will also find additional contextual and operational information about how specific tools and approaches work and the contexts in which they operate. This information is to ensure users appreciate the differences among various types of evidence and interpret evidence correctly.
