Are you passionate about driving a global understanding of sustainability in agriculture and food, especially in the poorest countries?

COSA began with a handful of volunteers committed to finding globally comparable metrics for understanding sustainability in agriculture. Today, as a nonprofit organization operating at the forefront of sustainability, COSA thrives on the gift of skilled volunteers to work together in the virtual space with us in creating a better world.

Michelle Herzberg contributed to COSA’s communication efforts and in the process, she tells us, learned more about economic and social sustainability, sustainable impact assessments, and got a deeper understanding of how sustainability efforts make lasting impacts throughout the agriculture supply chain. “I started volunteering with COSA to get more experience in the sustainability field since I am studying Environmental Science and Sustainability at the University of Pittsburgh, and hope to work in this area after graduating this year. I enjoyed this experience and know I will use the knowledge I’ve gained from volunteering with COSA later in my professional career.”

Thank you, Michelle!
