The new project management systems adopted by IUCN in 2013 and last updated in 2016 is designed to ensure that IUCN (and institutions executing IUCN projects) will develop projects according to proper procedures and standards, will manage environmental and social impacts of projects in a rigorous manner, and will follow guidelines designed to promote performance (accountability, transparency) and improved outcomes. The project management system includes the Project Guidelines & Standards (PG&S) and the Environmental and Social Management System (ESMS). The key documents for the ESMS are: the Environmental and Social Management Framework (ESMF), the overarching governance and policy framework; four Environmental and Social (E&S) Standards and two E&S Guidelines; and the ESMS Manual describing ESMS procedures, tools and responsibilities.
