Abstract The purpose of this source book is to support skills planning entities to work with employers to identify and anticipate green skills needs and to build these needs into occupational descriptors and sector skills plans. Thus, the source book complements the existing Enabling Document (DEA, 2010b) and provides guidelines to support SETAs to embed environmental considerations, related occupations and green skills into their skills planning processes. Written by Presha Ramsarup and Mike Ward with contributions from Eureta Rosenberg, Nicola Jenkin and Heila Lotz-Sisitka. The Green Skills programme (2015-2018) helps key role players to plan for and develop green skills. It is a three-year programme funded by the Green Fund of the Department of Environmental Affairs (DEA) through the Development Bank of South Africa. The implementation partners include Rhodes University′s Environmental Learning Research Centre, the Centre for Researching Education and Labour (REAL) at Wits University, the University of Cape Town′s African Climate and Development Initiative (ACDI), the Further Education and Training Institute (FETI) at the University of the Western Cape, as well as several other environmental partners.
