Boston Climate Week 2026 is around the corner — and today, we’re sharing a big partnership announcement and a few important updates!

The inaugural Boston Climate Week (May 3 - 10) will bring together 5,000-plus attendees across over 100+ events to build community, accelerate climate action, and spotlight climate solutions.

Here’s what’s new:

  • Announcement: ClimaTech joins Climatebase as co-presenters of Boston Climate Week!

  • Event submissions are now open!

  • New ways to get involved as an attendee, organizer, volunteer, or venue host.

Boston Climate Week is proud to be part of the Climate Week Network, a growing alliance of city-based Climate Weeks around the world.

Boston Climate Week partners with CLIMATECH

Today, we’re excited to announce our partnership with ClimaTech — Boston’s premier climate innovation conference and now a co-presenter of Boston Climate Week alongside Climatebase.

Boston is one of the most important places in the world to host a Climate Week: a global center of research and innovation, home to world-class universities, a thriving climate and deep tech ecosystem, and a region on the frontlines of coastal and climate risk. It is a city where policy, science, business, and community sit close enough together to actually get things done.

For the past two years, ClimaTech has helped convene and grow Boston’s climate and sustainability ecosystem. Last year, its speakers included Massachusetts Governor Maura Healey, Boston Mayor Michelle Wu, MIT President Sally Kornbluth, and many more.

This year, ClimaTech 2026 returns to Boston on Monday, May 4 and Tuesday, May 5, with an exciting expansion to a new home at the Boston Center for the Arts campus, co-presenting Boston’s inaugural Climate Week with Climatebase.

Now in its third year, ClimaTech convenes leading voices from technology, business, policy, academia, and finance to accelerate real climate impact. The 2026 program will feature inspiring keynotes, engaging panels, interactive workshops, a vibrant international B2B expo, startup pitches, and meaningful networking across the climate ecosystem.

Across three core tracks—Scaling Innovation and Financing Growth, Enabling Systems & Market Transformation, and Climate Technology as a Business Opportunity—this year’s program for ClimaTech will explore how capital, infrastructure, and breakthrough technologies come together to scale climate solutions. Sessions will dive into FOAK financing, corporate pilots and market partnerships, energy for AI and grid optimization, and emerging technologies such as fusion, geothermal, long-duration storage, and critical minerals. The program will also spotlight workforce development, community resilience, and the real-world deployment of climate technologies across energy, buildings, and transportation.

Join fellow mission-driven builders, investors, and operators from around the world to deploy climate solutions and shape the next wave of climate innovation.
