The Green Expo, CORE's Annual Event, returns in 2026 at Aspen Meadows, bringing together sustainable businesses, products, and services from across the Roaring Fork Valley and beyond. This free, half-day event brings together industry professionals and community members to explore practical solutions to reduce carbon emissions.

We’re seeking exhibitors that are doing meaningful work in energy, electrification, and sustainable building for The Green Expo.

Interested? Contact Kate LaMair for details.

Calling all runners and Mt. Sopris enthusiasts! RFOV is partnering with the USFS, Wilderness Workshop and Alpine Performance Labs to host a day of trail improvements on the bottom portion of the Thomas Lakes Trail! Come join us on Carbondale's closest access trail to the Maroon Bells - Snowmass Wilderness! One grand prize will be raffled for all volunteers for free training sessions at Alpine Performance Labs!

Recently acquired by Pitkin County Open Space and Trails in 2024, Snowmass Falls Ranch is a 650-acre parcel that serves as a gateway to the Maroon Bells-Snowmass Wilderness. The area has over a century of ranching history as well as valuable wildlife habitat and stunning scenery. In its transition to public land, a key objective is the removal of biennial noxious weeds and the spreading of native seeds in order to restore the native plant community. Come help us restore this beautiful, wilderness-adjacent property for the third year in a row.

Join the Eagle River Coalition and Wilderness Workshop for a bilingual, hands-on exploration of the Homestake Valley, which is home to ancient fens. This rare ecosystem provides incredible biodiversity, native flora and fauna, is home to numerous threatened species, and functions as a critical carbon sink in a changing climate. Amid an ongoing drought and the threat of a potential transmountain diversion, inventorying and understanding the Homestake Valley allows us to better advocate for these places now and into the future. We’ll be using the iNaturalist app to photograph plant species and add to the ongoing bioblitz project.  Experts from Walking Mountains, Colorado Moutnain College, Roaring Fork Audobon, and Wright Water Engineers will be there to help you identify and document plant species and learn about this fascinating ecosystem in our backyard.

This annual celebration brings together this community to support the water, wildlife, and way of life that make this such a special place to call home. It's the best night of the year, gathering with you, and seeing what is possible with your partnership. Enjoy curated cocktails, a three-course dinner, and inspirational stories of conservation in your backyard.

We had such a great time at our 30th Anniversary project at the Maroon Bells, we thought we'd do it again in 2026! Come join RFOV, the USFS, and Wilderness Workshop for a day of trail improvements and targetted weed removal in the Iconic Maroon Bells Scenic Area!

Experience the sights and sounds during the time when day shifts to dusk in the cattail marsh, pond, and sedge meadow habitats of Rock Bottom Ranch. As red-winged blackbirds and song sparrows wind down their activities and wild turkeys fly up to safe roosts in the nearby cottonwoods, the snipes begin their winnowing display flights and Virginia rails start calling. We will experience this fascinating and brief window of time with the goal of learning about birds that are active at dusk and dawn. As daylight fades, our dominant sensory awareness will shift from visual to auditory and we will become immersed in a different and fascinating world.

While Colorado is excited to celebrate Bike Month every June, the highlight of the activities is Bike to Work Day on June 24, when employees leave their cars at home and enjoy bicycling to work. The annual free event draws tens of thousands of Colorado commuters who celebrate the day by swapping a ride in their cars for a ride on two wheels. Participating helps improve air quality, reduce greenhouse gas emissions, reduce traffic congestion. Plus, it’s fun! Studies have shown that people who commute by bike have the happiest commutes of all. Kick off your workday feeling energized, de-stressed and refreshed.

Join us select Thursdays at Rock Bottom Ranch to meet our colorful flock of laying hens, learn their breeds and role at Rock Bottom Ranch, and help collect our delicious multi-colored eggs.

What does it really mean to care for a landscape? It's a bigger question than we usually make room for and it's one worth sitting with. We talk a lot about showing up for the land. But what if the most important shift isn't in what we do but rather how we see the world around us?

Join us at the inspirational setting of Rock Bottom Ranch for an evening of birds and watercolor! The class will start off with a short birding outing with ACES Bird Guide Rebecca focusing on the Cedar Waxwing and other resident birds, their behavior, and how they interact with the environment. The students will then explore with Amy the various techniques, materials, and tools of watercolor to paint several perspectives of the Cedar Waxwing. One of the valley’s most beautiful birds, its silky plumage of browns, grays, and yellows is accented by its bold black mask and expressive crest. Let your creativity fly!

In the past decade and especially since 2021, state and local governments across the United States have announced billions of dollars’ worth of economic development incentives to attract and grow project-level investment in electricity infrastructure, clean fuels, and new energy technology manufacturing. Some of these projects are now online and have catalyzed local job growth. Others have been downsized or canceled entirely. Still others remain in the pipeline but with evolving timeframes. This uncertainty raises questions about whether and how state and local governments should design and disburse incentive packages, particularly for large projects.

Carshare programs offer convenient, flexible, and affordable options  for residents across the United States. EV carshares make it easier to refuel and reduce local air pollution.

These advantages are especially helpful for residents of multifamily housing, who may struggle with the high costs of vehicle ownership, barriers to convenient EV charging access, or both. By integrating EV carshare into multifamily properties, cities and partners can expand mobility options, reduce parking demand, and advance community sustainability goals, all while delivering tangible value to residents.

Carbondale Aquatics Center Opens May 23rd!

The high altitude sagebrush shrubland ecosystem abounds with wildlife activity at first light when the sun is still below the horizon. Early morning in this iconic landscape is a magical time to experience the dawn chorus of breeding songbirds, including the Brewer’s sparrow, whose distinctive, buzzy song carries amid the voices of other birds.

Affordable energy bills have never been a higher priority: as utility rates rapidly rise and become more volatile in many regions of the US, residents and businesses are clamoring for a lifeline. At the same time, national bodies that publish model energy codes and standards are stepping back from ambitious, cost-effective energy efficiency improvements, especially those that recognize the exceptional performance of electric heat pumps. In 2024, RMI and the Public Health Law Center published the Zero Fuel Bias Overlays, a set of template energy code amendments intended to address this gap.

Immerse yourself in the vibrant world of high-altitude pollinators at our interactive summer celebration at Rock Bottom Ranch. This family-friendly afternoon kicks off with a series of experiential stations where science meets creativity. You’ll have the rare opportunity to use professional microscopes and specimens with world-renowned entomologist Dr. David Lohman to see the intricate details of butterflies invisible to the naked eye. 

Join us for a grounded, forward-looking conversation on how real energy progress gets built, especially in moments of uncertainty.

This conversation features RMI’s CEO Jon Creyts and Co-Founder Amory Lovins, alongside program leaders Sarah Ladislaw, Debbie Gordon, and Vikram Singh. They’ll share practical, nonpartisan solutions that strengthen affordability, reliability, and energy security — drawn from RMI’s decades of work building and scaling real-world solutions.

Join us for the 17th annual Bonedale Bike Week! May 11th-17th 2026. In Bonedale, Colorado
