Josh Garrett, CEO and co-founder of Redwood Climate Communications, is on a mission to help curb the climate crisis with storytelling, strategic communications, and collaboration. He has 18 years of experience in strategic communications and marketing, with 12 of those years devoted to clean energy and climate tech.

After getting his start in various marketing and communications roles, Josh discovered the inspiring world of clean energy technology in 2011. That discovery led Josh to pivot his career toward cleantech and environmental advocacy by earning a master’s degree in environmental science and policy from the Earth Institute at Columbia University. 

Following his graduate program, Josh’s turn to cleantech and sustainability comms led him to marketing and communications roles at environmental nonprofits The Nature Conservancy and Equitable Origin, where he led development of messaging and communications strategy around energy issues. Josh joined the agency world in 2016, when he joined  Antenna Group as an Account Director. Over five years at Antenna, he led teams working with climate tech giants including Google Nest, Stem, and Sunrun, and earned a promotion to vice president. As VP, Josh continued his client work and expanded into personnel management, business development, crisis communications, and business planning.

Josh co-founded Redwood with Dave Donohue and John O’Brien of SBS Comms in September 2021. Since founding Redwood, Josh has led growth of the company while maintaining its commitment to facilitating climate progress and continuing to work directly with all Redwood clients. Josh lives in New York’s Hudson Valley and enjoys the beautiful parks and trails of the region as a hiker, mountain biker, fly fisherman, and snowboarder. Whenever he can, Josh relishes the opportunity to explore the depths of the sea on SCUBA dives, with Shipwreck Point in Curaçao (photo) being his preferred destination.

Climate interests & expertise: Josh loves discovering new, “twofer” climate technologies (e.g. a machine that purifies drinking water and generates clean electricity) but is also jazzed about the reliability, versatility, and massive potential of energy storage in all its forms. He has extensive experience messaging and pursuing media relations related to the voluntary carbon market (VCM) and carbon offsets/carbon credits.

Favorite place of tranquility: The high-altitude lakes and streams of the Sierra Nevada mountains.
