Rosalyn has brought environmental education through her work in education for sustainable development around the world. Through the Education for Sustainable Development Toolkit and her numerous workshops and conferences abroad, she has engaged educators in reorienting curriculum to balance the three components of sustainability -- environment, society, and economics.

Many countries around the world educate for a better future, but that future is not necessarily mean more sustainable. Instead the focus is on education and innovation that supports the economy. Through her work Rosalyn has introduced balancing economic interests with education that addresses environmental concerns, social justice, and quality of life for all Earth’s inhabitants, both human and nonhuman.

Rosalyn's Education for Sustainable Development Toolkit (ESDTK) is an easy-to-use manual to create education for sustainable development (ESD programs. The ESDTK encourages communities to dovetail their efforts with those of education systems and organizations to create education programs that meet local sustainability goals. The ESDTK was fist published in 2000 and version 2 was published in 2002. The ESDTK has received over 115,000 hits on the Internet, where it is distributed free of charge.

Rosalyn has received requests for permission to translate into nearly 20 other languages. Chinese and Urdu translations were published for the launch of the United Nations Decade of ESD.

Rosalyn has responded to numerous requests for lectures, attendance at conferences, and consultations around the world during the last three years. In 2006 alone she made 11 international trips to eight countries including Canada, Thailand, Malaysia, Germany, Finland, Kenya, France and Japan.

 
In 2006, she also played an advisory role to three UN agencies around the UNDESD. Her work has inspired education professionals from dozens of countries around the world. She humorously reports that at conferences, the logo for the ESD Toolkit is more recognized than her name. She likes that the work of ESD is more popular and important than she is.
 
Rosalyn is also the author for the Guidelines and Recommendations for Reorienting Teacher Education to address Sustainability along with Charles Hopkins and the International Network of Teacher Education Institutions. The document is published in the six UN languages. The English version has been totally distributed in hard copy and is available off the Internet. This group of authors has brought environmental education to ministries of education, institutions of higher education, and other organizations through the vehicle of ESD. In some cases these are the same institutions that paid scant attention to EE during the international environmental education initiative in the 1970s and 80s.
 
In the mid-1990s Rosalyn was involved in efforts to establish environmental education in Russia. She helped organize the River-to-River a Russian-American summer exchange program for teachers. The four-year program involved about 60 teachers and touched the lives of hundreds of students who learned a lot of ecology and community investigation skills and that Russians and Americans are a lot alike.
 
Rosalyn has also been active in NAAEE. Her most recent volunteer position was a Chair of the Sustainability Education Commission (SEC). In establishing the SEC, she was able to involve an international audience that hail from countries that are more interested in ESD than a traditional EE approach to education.
