Sponsor the Michigan Climate Summit

Be the reason Michigan’s climate community gathers — and the name they carry forward

Climate Summit

Introducing Our New, Improved Sponsorship Experience:

We’ve heard your feedback. This year, instead of individual tables for organizations and paper programs, we’re moving toward a new, improved paperless summit experience powered by our first-ever summit mobile app. Your brand will still command the big screen in every room, but now it goes further. With 600+ attendees carrying the app throughout the day, your sponsorship reaches people right where they are — on their phones.

Our new digital program comes with exciting features built specifically for sponsors:

Ad sizing tailored to your sponsorship level
Full flexibility to update your ad anytime
Get your actions, donation pages, and information to all attendees without needing to spend time staffing a table

See the Summit app demo and sample ads

And your impact doesn’t end when the event does. Your brand will be permanently featured on our official 2026 climate sponsors webpage, keeping your visibility alive long after the closing remarks. For those who still prefer the analog experience, our network sessions and the physical bulletin board will be available for distributing flyers and meeting other attendees.

We have upgraded all sponsorship levels to include an ad! See below.
