David Macek

David Macek is the executive director of EcoChallenge.org, a sustainability organization that provides innovative social and digital tools as a launchpad for people to experience “a-ha” moments that lead to extraordinary environmental and social change.

One of EcoChallenge.org's signature offerings on their digital platform is Drawdown EcoChallenge—where schools, businesses, and communities come together to activate climate solutions.

In the first two challenges, more than 21,000 people from 79 countries took more than 200,000 actions during the three-week events.
