Committee on Sustainability Assessment

  • 83 people are interested

At the Committee on Sustainability Assessment, volunteering can offer insights and awareness of challenges to the sustainability of some of our core food systems: coffee, cocoa, tea, and more. Nearly one-seventh of the world’s population depends on farming for their livelihoods. They are among the most vulnerable workers or families anywhere; most are small farmers working small plots of land. We are looking for people who feel as passionate as we do about understanding global sustainability and want to help us grow public awareness of the issues:

  • Who will grow your coffee in the future?
  • What happens when a company discovers child or forced labor in its supply chain?
  • How can farmers build resilience?
By measuring on-the-ground realities in a neutral, unbiased way, we learn what is working and what is not in sustainable agriculture.

We are looking for communications support. If you are good at putting sometimes complex but cutting-edge subject matter into simple, easy-to-understand language, for short assignments, we would love to hear from you.

Mission Statement

COSA's mission is to advance systematic and science-based measurement tools for understanding, managing, and accelerating sustainability. We envision a world with a balanced and global understanding of the environmental, social, and economic dimensions to mutually advance sustainable agriculture.


The need for a coherent agreement on what sustainability means, and how to practically measure it, was the impetus for the genesis of COSA. In agriculture, major challenges include poverty, food security, water scarcity and pollution, basic human and labor rights, land degradation, loss of biodiversity and climate change. For many, the knowledge that two-thirds of the world’s poorest are actually farmers in developing countries represents one of the most profound failures of modern agricultural development. Today, COSA's stakeholders view us as a neutral authority on sustainability measurement because of the scientific rigor applied, and vetting by many of the world’s most influential institutions. We work in the public and private sectors for advancing a common global language around sustainability.
