The Green Initiatives Database covers campaigns, projects, networks, research and training activities in which unions are or have been involved, proactively or reactively, directly or indirectly (but significantly), alone or as partners, across Europe and the USA. The information in the database was collected by Linda Clarke and Dimitris Stevis, in a process described in their 2017 presentation "Green Transitions in the US and Europe: Breadth, Depth and Worker Agency" (https://yorkspace.library.yorku.ca/xmlui/handle/10315/39299/). Their working papers also relate to this research, especially: - Stevis (2019), "Labour Unions and Green Transitions in the USA: Contestations and Explanations" (https://yorkspace.library.yorku.ca/xmlui/handle/10315/39419/) and - Clarke, Sahin-Dikmen and Gleeson (2018), "Green Transitions in the Built Environment: Europe" (https://yorkspace.library.yorku.ca/xmlui/handle/10315/38829/). This database was created in Wordpress, originally on the Adapting Canadian Work website, at https://adaptingcanadianwork.ca/green-initiatives-database/. We have exported the information and reformatted it into a PDF organized by initiative type.
