Marc Hertz
Storytelling Manager, 1021 Creative

Marc has more than 20 years of writing and editing experience, and his passion is climate change, specifically informing others about the issue and, in doing so, helping move the collective needle toward action. In the lead-up to COP21 in 2015, he initiated and co-lead the Webby-awarded #OursToLose climate change campaign on YouTube's Spotlight channel. With the help of popular YouTube creators, the campaign targeted what we could lose because of climate change, and helped drive people to sign an Avaaz clean energy petition. In 2019, he launched, a site discussing the intersection of climate change and politics. He graduated with a broadcast journalism degree from the University of Colorado at Boulder.
