Houston Climatetech Summit 2026

The annual Greentown Climatetech Summit is the premier gathering of entrepreneurs, investors, corporate leaders, policymakers, and philanthropists accelerating the climate, energy, and industrial transformation.

Once a year, we open the doors of our incubators to the people working hardest to move all of it forward. On Sept. 16 in Houston and Oct. 29 in Boston, step inside our labs to meet our 260+ climatetech startups, hear perspectives from industry leaders, and forge connections with changemakers across the ecosystem.

Attend your way. Climatetech Summit offers multiple ways to participate:

Full-Day Admission: Includes morning programming, lunch, the Startup Showcase & Open House, and the evening Pitch Competition & Happy Hour.

Afternoon Showcase Admission: Includes afternoon access to the Open House & Startup Showcase, and the evening Pitch Competition & Happy Hour.

Virtual Admission:  Livestream access to the morning programming only.

This isn't a conference confined to one room. Throughout the day, you'll move through Houston's dynamic Ion District, from thought-provoking conversations at The Ion to hands-on innovation inside Greentown Labs, ending with an evening celebration at the legendary Continental Club. Each stop offers new opportunities to discover groundbreaking technologies, meet industry leaders, and experience why Houston is where climate innovation comes to life.
