The Laureates

Climate Curve's Keeling Curve Prize works to spotlight the most promising projects that are actively reducing, removing, or replacing greenhouse gas emissions or increasing carbon capture in our atmosphere. These incredible and groundbreaking Laureates have been selected by our team of climate experts as the most effective climate solution in their respective categories. Each category addresses a specific sector of climate innovation:
