In 1988, Huston left the IUCN to become Director of Public Affairs for the International Planned Parenthood Federation. There she was charged with creating a new department to enhance the Federation's global visibility through publications, media, conference organization and coalition-building.
The IPPF and IUCN worked closely together on population and planetary environmental issues; Huston maintained her connection to the IUCN by serving as a member of the IUCN's Commission on Education and Training to establish a network among women educators, trainers and communicators. While a part of this commission she served on both the Womens' Involvement in Environmental Education and Communication subcommittees.
