The environment and conservation are a top focus of time-limited philanthropic institutions, a report from Rockefeller Philanthropy Advisers shows.

Time-limited, or spend-down organisations, aim to complete their philanthropic projects within a specific time-frame and they have grown rapidly: Nearly half of all organisations established since 2010 are time-limited and most of them want to spend their entire budget within 20 years.
