We're on a mission to maximize the impact of sustainability leaders.

TSC was founded with the shared belief that in order to accelerate the transformation of organizations worldwide, there needs to be a strong collective of highly skilled sustainability leaders who come together and help each other succeed. At TSC, they give each other support on their most critical decisions, elevate their leadership skills through tailored leadership programming, and make powerful lifelong relationships.

“The Sustainability Circle is a private club for sustainability leaders that has been specifically designed for their challenges and needs. ”

The image features a series of concentric circles in a lilac hue against a black background, creating a target-like design. Distributed evenly along these circles are multiple individual portraits, each encased in a white circle with a drop shadow, which adds a sense of dimension. The arrangement of the portraits along the circular paths suggests a network or interconnected community of individuals. The diversity in the appearance of the people reflects a range of genders, ethnicities, and ages, implying an inclusive and global group. The design is a metaphor for community engagement within a digital platform or service.
