The fonds primarily includes records that were produced and acquired by Greenpeace Canada, such as research and publications to support their campaigns and projects. Notably, this includes jointly produced documents with other environmental non-governmental organizations (ENGOs) to coordinate their efforts in Clayoquot Sound and the Great Bear Rainforest. The records of Greenpeace International within this fonds reflect their broader campaigns to inform people and shape public opinion to oppose the clearcutting of old growth forests in Canada and elsewhere in the World. Records by Greenpeace Canada primarily include their efforts to cooperate with environmental non-governmental organizations, First Nations, forestry companies, and governments to achieve greater protection for old growth forests. The primary types of records include reports, communications, legal advice, court cases, planning materials, photographs, maps, ephemera, and posters. Most of the records in this fonds produced by Greenpeace Canada is from their Vancouver office. The fonds is organized into the following series: Clayoquot Sound Campaign and Protests (1980-2017), Great Bear Rainforest Campaign and Protests (1980-2017), Forest Stewardship Council (1992-2017), Rainforest Solutions Project (1991-2017), Research and Resource Collection (1979-2017), Ephemera and Posters (1993-2016), Maps (1964-2015), and Multimedia (1988-2007).

The collection reflects the forestry operations and projects undertaken by Western Forest Products and their predecessors. The majority of the material dates to the 1980s, with some material dating to as early as the 1950s and as late as the early 2000s. Much of the contents relates to MacMillan Bloedel Limited, in particular their tree farm licenses (TFLs), silvicultural practices, and some corporate information.

Tree farm license records include: project reports, working and management plans, and maps. Silviculture records include: growth and yield reports, environmental reports, literature, and summaries of silvicultural projects. Corporate records include meeting agendas and minutes, publications, and microfiche.

There are three main types of material in the collection: textual records, maps, and microfiche. The initial acquisition also included aerial photographs which have subsequently been transferred to the UBC Geographic Information Centre.
