The Mountain Towns 2030 Climate Summit is the premier annual gathering of leaders from mountain, resort and rural communities, working together to achieve carbon neutrality.

Since launching in 2019, the Summit has evolved into the pre-eminent networking and knowledge-building event for key local stakeholders committed to accelerating climate action in mountain, resort and rural communities throughout the US.

The 2026 Summit heads to Sun Valley, Idaho, with the iconic Sun Valley Lodge as our home base.

Built for action, this two-day gathering brings together the nation’s leading climate voices for inspiring keynotes, peer-driven breakouts, and meaningful connections—on and off the agenda.

Designed to spark collaboration and accelerate real-world solutions, the Summit connects leaders from mountain, resort, and rural communities of all sizes.

Join a community turning climate ambition into action.

“More so than most conferences, it was clear that everyone involved is driven by a deep and sincere love of place, of home. And with that love of place — along with all the limitations and restrictions that come with being a small place in a large landscape — comes a certain pragmatism and creativity that are, in our hyper-ideological times, incredibly refreshing.”

“If, like me, you’re doing climate work in rural America, in small towns, in communities that don’t make headlines—find your MT2030.

Find the conference where your actual challenges get airtime. 

Where the person next to you is solving the same problems you face Monday morning. Where peer learning isn’t a buzzword but the entire point. 

Climate action doesn’t just happen during Climate Week.  It happens in communities you’ve never heard of, led by people doing some of the hardest work with the fewest resources. That work deserves its own spotlight.”
