As the action and drivers for climate urgency build, every job holds the potential to be a sustainability job – from the factory to the boardroom. Sustainability knowledge is in high demand, and it’s an exciting field to join. For many professionals, they are entering sustainability from wide-ranging sectors to find a community of passionate, intelligent collaborators who genuinely seek the common good over individual gain.
ISSP strives to be a global community of changemakers and collaborators from 94 countries in public, private, non-profit, and nature spheres. Leaving competition at the door, we work together to provide the networking, training, and tools needed to meet goals and create sustainable change. I am proud to share our progress in this mission of accelerating impact and manifesting sustainable change.
In 2023, we invested in our digital presence and collaboration spaces, launching online discussion forums for members and a new website – this was no easy feat and well executed. Launching nine new courses, we were able to provide training in topics ranging from sustainable procurement to career development.
We then made strides towards fostering diversity within our community, increasing our international membership to 36%. We also managed to increase our webinar registrants by 56% and our live and self-study course enrollment by 34%.
We marked our 15th anniversary, celebrating not only our past journey and the people who built this network, but also the promise of a more sustainable future. I attended Sustainable Brands in San Diego this year, and it was heartening for me to hear many people share how ISSP helped them and guided them on their sustainability journey. We at ISSP want to grow this experience by making sure we stay relevant with our credentials, courses, study materials, webinars, and communities of practice.
COP 28 was a reminder of the urgency of our mission with emphasis on (1) fast-tracking a just, orderly and equitable energy transition, (2) climate finance, and (3) a focus on people, lives, and livelihoods.
It was also my privilege to welcome Gary Tong, Nicole Cacal, and Desta Raines to the ISSP Governing Board, knowing that their expertise and global perspectives will guide us in meeting the evolving needs of this community. Thank you to my other Governing Board colleagues for their guidance and expertise as we transitioned into a post-COVID world. An exceptional thank you goes out to our ISSP team – Michelle, Alex, Sarah, and Aqsa for their dedication and inspiration. It has been a pleasure working with them.
As a professional body of sustainability practitioners, sustainability and regeneration is everyone's work and we can work together to solve our climate and humanitarian challenges. We at ISSP aspire to be at the center of every aspect of work.
Thank you to everyone who was involved in our community, both this year and over the last 15 years.

Expanding our community to organizational members
In 2023, we welcomed seven new organizational members from diverse industries and countries, such as Saudi Arabia, Uganda, and Canada. Our goal with this program is to develop a global network of organizations committed to a sustainable future. As members, their teams will gain foundational training across departments and a community to lean on as they learn. We also opened organizational membership to higher education institutions, slowly transitioning existing education partners to the organizational membership program. This provides their faculty and students the same access to membership benefits, while connecting them to the larger network.
Training for global goals
Accelerating impact
Through strategic programming initiatives, ISSP enhanced its outreach and impact in advancing sustainability professional development. We collaborated with leading organizations and experts for our technical webinar series, resulting in a 56% surge in registrants. The topics ranged from sustainability forecasting with NielsenIQ to gender dynamics in the workplace with Reimagine Gender, providing capacity-building opportunities across the UN Sustainable Development Goals (SDGs).
Our dedication to career growth is reflected in the rise in individuals using our growing library of 35 courses, nine of which were added this year. Additionally, we supported members in advancing their sustainability and career goals through curated thought leadership in the ISSPBlog, featuring international experts like John Elkington, Gwen Migita, MBA, and Bobuchi Ken-Opurum.
