This dataset includes information on fossil fuel divestment commitments that took place as part of the fossil fuel divestment movement through Mar. 23, 2018. The dataset includes the following variables: name of organization, type of organization, home country of organization, type of divestment commitment, date of divestment commitment, and total assets under management of the organization committing to divest. Divestment commitment data was shared with the authors by 350.org. The authors verified and made corrections to two subsets of the data: organizations with assets under management of at least $1 billion which committed to fully divesting from all fossil fuels, and organizations with assets under management of at least $90 billion which committed to divesting from some, but not all, fossil fuels. 350.org granted permission for the data to be made public.
