The Cleantech Leaders Climate Forum expands our mission through a public-facing 501(c)(3) platform. It produces high-impact programming to elevate strategic dialogue, foster cross-sector collaboration, and educate broader audiences on the importance of advancing resilient infrastructure, energy innovation, and environmental stewardship.
“CTLR is a community of the innovators and thought leaders in the Cleantech industry. CTLR gives me the opportunity to foster relationships with investors, cutting edge CEOs and senior policy advocates which go beyond the normal course of business. These connections are simply unmatched by any other industry organization.”
Nancy Floyd
Investor, Board Member, and Clean Energy Pioneer
“CTLR epitomizes Margaret Mead's adage ‘Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has.’ CTLR brings together leaders who have not only have a common mission to save the world, they want to help each other succeed in doing it.”
Richard Kauffman
Chairman of NYSERDA and Generate Capital
“The group we founded to give cleantech a bigger voice has grown into a thriving community alongside the sector. Now my own green hydrogen start-up is co-hosting CTLR events at renewable energy conferences, to which we can invite potential clients and partners who share our vision. The ecosystem we're creating together is helping us all to collaborate with other leaders in the field and speed up the transition to a low-carbon economy.”
Jacob Sussman
SVP, Development of Electric Hydrogen and CLTR cofounder

What is the Cleantech Leaders Roundtable?
CTLR is a private, high-trust community for senior executives, investors, and innovators driving the clean energy transition. We bring together leaders across the cleantech and climate sectors to share insights, collaborate on strategies, and connect capital with innovation.
Who can join?
Membership is by application and invitation only. Our community is intentionally kept at the C-suite and senior leadership level — founders, CEOs, investors, and senior executives advancing energy independence.
What do members get?
Members gain access to curated events including strategy summits, dinners, and Cleantech Coffees - as well as a private Slack network, introductions across our national chapters, and opportunities for peer exchange, investment, and policy engagement.
How is CTLR different from other industry groups?
CTLR isn’t a trade association or lobbying organization. We focus on business collaboration, strategic connections, and candid dialogue, not public advocacy. Our events are off the record, high-trust, and designed to move ideas into action.
