On 2025-05-13, the 'EUPHRESCO III Open Data Webinar' took place online.  Open data is considered the new oil. As oil can be used to produce fertilizers, lubricants, plastics and many other derivatives, so data is considered the commodity to use and re-use to create value.  Opening research data and publishing open access articles and documents have become a requirement for many publicly funded research projects. In line with the responsibilities of research funders and their networks, that have a pivotal role in promoting FAIR practices and in advancing open science, this webinar was organized to raise awareness about the benefit of open science, to provide an overview of the international framework, showcase the perspectives of public and private donors and present what has been done in the framework of Euphresco and EUPHRESCO III to support the plant health community.
