Yale Blue Green (YBG), a shared interest group of the Yale Alumni Association (YAA), is led and supported by Yale alumni and serves as a hub for thought leadership, collaborative action, lifelong learning, and social impact on a range of topics relating to the environment and sustainability. We represent a robust community of leaders, volunteers and members drawn from the entire Yale alumni population. All alumni are welcome to join us.

We are building a network of local chapters, and we also create digital community through online programming, webinars, monthly calls, and social media.

Yale Blue Green’s alumni members are located across the United States and internationally. Our chapters are an opportunity for alums living in major cities to connect with fellow alums where they live and work, and to engage with environmental and sustainability issues that are unique to their area. We currently have chapters led by local co-chairs in:

• New York City
• Boston
• Washington D.C.
• Chicago
• San Francisco
• London

How does YBG work?

YBG operates with the goal of facilitating three levels of connection and community-building:

Alumni-to-Alumni: We create community by connecting and engaging Yalies interested in environment and sustainability issues through events and programming in our chapter network. We organize and participate in sustainability-related civic projects, lectures, social events, outdoor excursions, advocacy efforts, and Yale Day of Service projects.

Alumni-to-University: We support the Yale Office of Sustainability and University sustainability efforts, including the ‘greening’ of alumni events such as the Yale College Reunions and Assembly.

Alumni-to-the -World: We support alums working on the frontlines who are building new organizations and institutions, and pioneering innovative approaches to public engagement and climate action.
