What Harvard Alumni for Climate and the Environment does

Harvard Alumni for Climate and the Environment (HACE) is an independent, volunteer-run nonprofit organization founded in April 2020 and incorporated in the Commonwealth of Massachusetts. It operates as an official Shared Interest Group (SIG) affiliated with the Harvard Alumni Association, serving a global community of more than 3,700 Harvard alumni, staff, fellows, and other affiliates who work to address the climate crisis. The organization is entirely volunteer-led with no paid staff, governed by a Management Committee comprising alumni from multiple Harvard schools (HBS, HLS, HGSE, HKS, SEAS, HSPH, College, HES, GSAS).

HACE's core product is a community platform offering interconnected programs: the HACE Book Club (entering its 5th year), a Mentorship Program, Learning Circles, and the Harvard Climate Entrepreneurs Circle (a nine-month incubation program launched in 2021 with Harvard Innovation Labs and the HBS Business and Environment Initiative). Additional offerings include a Climate and Health Programming Series, Climate Job Search Resources, and a comprehensive events program including Climate Week NYC and Harvard Climate Action Week participation. The organization utilizes entirely third-party technology platforms—Squarespace for its website, Slack for community, Zoom for events, LinkedIn for networking, Mailchimp/Sendgrid for communications, Airtable for CRM, and Zeffy for donations.

HACE's revenue model is donation-based. Membership is free and open to all Harvard affiliates with a Harvard email address; the organization has no paid products or services. Donations are accepted via credit card (through Zeffy), Zelle, and check, and the organization is pursuing 501(c)(3) tax-exempt status. Growth is community-led and event-driven, relying on word-of-mouth referrals, LinkedIn, Slack engagement, and member recruitment. The organization has regional leads in Boston, New York, Washington DC, Texas, London, Asia, and Africa, and partners with Harvard Innovation Labs, the Salata Institute for Climate and Sustainability, Harvard Career Center, and regional Harvard Clubs.

Others

Climate Reality Project: Global climate education and advocacy organization founded by Al Gore. Listed as a recommended partner on HACE's Beyond HACE directory.

Environmental Defense Fund: Major international environmental advocacy organization operating across climate, health, and ecosystem topics. Comparable in mobilizing climate-engaged professionals and advocating for climate solutions, but operates as a large established NGO rather than a volunteer-run alumni network.

Emerging players

Terra.do: Climate learning and career-transition community offering fellowship programs for climate professionals. Comparable in addressing climate career transitions, learning, and community-building needs that overlap with HACE's mentorship and learning circles offerings, though operates as an open platform.
Climatebase: Climate-focused professional community and job-matching platform serving climate-interested professionals across institutions. Comparable in addressing the climate-career networking and job-search use cases HACE targets, but operates as an open cross-institutional platform rather than an alumni-gated community.

Directly comparable as a peer-institution alumni climate organization with a similar volunteer-driven structure and a parallel focus on climate education, advocacy, and career support.
